Low pressure was sliding it’s way northeast and away from northern Minnesota during the middle of last week. There was even the suggestion that a snowflake could fall near Duluth early on Thursday morning, with some chilly raindrops a sure bet. Indeed, there was a drop or two of rain but it never cooled enough for snow at Duluth. Temperatures did plummet on Friday morning, diping to the mid 20s, but then, they recovered all the way to the low 60s on Friday afternoon. The Weather Channel and Victoria-Weather ended up locked horns for the tie in Duluth. Actuals: Thursday – .09 inche of rain, High 52, Low 37 Friday – High 63, Low 26
One persistent problem that hasn’t gone away, even with improvements to forecasting and technology is the reception of a weather forecast, in particular during alert or warning periods. NPR recently released an article that highlights the number one issue with weather forecast reception among the public.
I reached out to some meteorologists and social scientists in the process of writing my book, (which comes out next month!) and more than any discussion on a particular type of weather phenomenon, the dissemination of alerts and warnings stood out as the most problematic issue with regards to operational meteorology. While meteorologists can continue to refine our communication of the severity and immediacy of a weather situation, it’s hard to tell someone to be vigilant of the weather in their area, if they don’t even know where their area is.
The NPR Facebook post for this article had many commenters claiming that James Spann’s methods for testing this out were flawed. How can anyone figure out where they are if you are given a map with only county and state lines? If you are given a state, I would posit, you should be able to know, roughly, what part of the state you are in. This should take only a couple of glances at the map to get yourself a rough idea. Failing that, warnings are given on a county basis. Learn county names, and you are a step ahead of the game.
Admittedly, I grew up as a kid who loved looking at maps and knowing where I was. I’m visiting relatives as I write this, and I know exactly where I am on a map of South Dakota, just as much for my own interest as for the benefit of receiving weather information (we did get thunderstorms overnight, though they were not severe). Also, I’ve been looking at maps for my entire professional career, so that is surely a benefit to me. That said, I don’t think it’s unreasonable to address one’s physical location in schools across the country at an early age. If it’s too late for some older people, perhaps we can inform young students and THEY can help their parents along the way.
For it’s small size, the state of Massachusetts is a compelling weather state. From the exposed Cape Cod to the mountains of the western Berkshires, there are a lot of different scenarios at work. It’s a difficult place to get a handle on for meteorologists, and not just because Massachusetts is hard to spell.
At 3:53PM, ET, Springfield was reporting a temperature of 67 degrees with overcast skies and a brisk south wind. Low pressure over western Pennsylvania was becoming quite occluded, with warm air surging up the east coast and pushing the occluded/cold front offshore. An inverted trough was brining general rain showers to the eastern Great Lakes, and would be drifting through New England through today. The upper level trough will be overridden by a more laminar flow through eastern Canada. The surface low pressure is going to continue to weaken and lose momentum as it slides into New England. Still, a little bit of shower activity will sneak in tomorrow, and the system will revitalize over the ocean and increase the chance for rain and thunder through the day on Monday. Tomorrow – Scattered showers, High 70, Low 54 Monday – Mor overcast with a better chance for rain, High 67, Low 48
TWC: Tomorrow – Cloudy. Slight chance of a rain shower. High – 67, Low 54 Monday – A mix of clouds and sun in the morning followed by cloudy skies during the afternoon. Slight chance of a rain shower. High 68, Low 48
AW: Tomorrow – Times of clouds and sun High 67, Low 52 Monday – Periods of rain High 66, Low 47
NWS: Tomorrow – A chance of showers, mainly before 9am. Mostly cloudy, High 66, Low 52 Monday – Showers likely, mainly after 2pm. Mostly cloudy, High 66, Low 48
WB: Tomorrow – Mostly cloudy. A chance of showers in the morning, High 65, Low 54 Monday – Showers likely, High 65, Low 46
WN: Tomorrow – Cloudy with heavy showers, High 66, Low 55 Monday – Nostly cloudy with light showers likely High 66, Low 48
FIO: Tomorrow – Mostly cloudy throughout the day. High 68, Low 54 Monday – Mostly cloudy throughout the day. High 68, Low 48
Showers earlier today encircled the region, but looked ominous south of Long Island.
Not unlike today, there were strong thunderstorms over the lower Mississippi Valley. When we looked at the weather in Texarkana, many outlets sounded the alarm, prospecting for severe weather in the region. In fact, when storms really got going, Texarkana was entrenched in heavy rain and wasn’t destabilized enough for severe storms. Temperatures couldn’t even climb out of the 60s, but in better news, it remained cool because the system was almost out of the area already, and Sunday was a much quieter day. Forecast.io had nearly perfect numbers Actuals: Saturday – 1.26″ of rain, High 59, Low 55 Sunday – High 65, Low 45
Google recommends two routes between Ogden and Duluth. One of them only has Fargo as the largest town between the two destinations. We’re going to take a more southerly route, in which we will pass through the Twin Cities. It’s a little less lonely. The drive will take 2 1/2 days and cover 1381 miles. Our pace will be 67.1mph, which means that the first two days will intend to conclude after 536.7 miles. Hope you like country music, because I bet there isn’t much else on the radio.
DAY ONE (Friday) The worst place to get stuck in the weather is the mountains. Slick roads plus climbs and drops and it can get a little dicey. Well, we are in Utah, and they don’t like dice. There will be high pressure in the northern Rockies tomorrow, holding a developing area of low pressure up in Canada while it warms up along our route. We will get to the sleepy eastern Wyoming town of Mule Creek, which is north of Lusk.
DAY TWO (Saturday) Another advantage to the southern route, aside from seeing actual human beings, is that the area of low pressure moving through Canada won’t carry enough cold air or momentum to intercept us as we pass through South Dakota or southwest Minnesota. We’ll make it to Mountain Lake, Minnesota with dark clouds with no rain on the northwestern horizon as we end the day.
DAY THREE (Sunday) If there is any precipitation with the passage of this cold front, it will be overnight as we recline in Mountain Lake. The cold front will be through southern Minnesota, so cool conditions will return as we head towards Duluth. Duluth is a very nice town, and because of Lake Superior it is always a little cool. Bring a jacket!
It’s the middle of April, and, disgusting though it may sound, we can’t officially exclude snow from the forecast. Not without a thorough examination, anyway.
At 416PM, CT, Duluth was reporting a temperature of 41 degrees with drizzle and a brisk northwest wind. The temperature across the border in Superior, where wind was more directly coming off the Lake of the same name, was only in the mid 30s. No snow is presently being reported in northwest Wisconsin, but it is certainly not out of the question as cold air continues to filter in. Low pressure will track from southeast Minnesota, through central Wisconsin and into northern Michigan, which will be near enough to Duluth that cold air won’t really sneak in until late in the game. There will be a little bit of leftover moisture overnight when the temperature profile is most likely to permit snow in the early morning hours tomorrow. There will be a quiet period Thursday afternoon, followed by a very pleasant day on Friday. An area of low pressure moving through northern Saskatchewan will drag warmer air north by Friday evening. Tomorrow – Cloudy with drizzle in the morning, then sunny, High 51, Low 37 Friday – Sunny and warmer, High 60, Low 36
TWC: Tomorrow – Cloudy with light rain early. Snow may mix in High 51, Low 36 Friday – Sunny skies High 56, Low 31
AW: Tomorrow – Mostly cloudy, a brief shower or two, High 49, Low 36 Friday – Mostly sunny; not as cool High 56, Low 33
NWS: Tomorrow – Rain likely before 7am, then showers likely, mainly between 7am and 2pm. Mostly cloudy, High 49, Low 37 Friday – Sunny, High 57, Low 32
WB: Tomorrow – Mostly cloudy. ain showers likely in the morning then a chance of rain showers in the afternoon, High 51, Low 38 Friday – Sunny, high 57, Low 33
WN: Tomorrow – Mostly cloudy with light showers likely, High 48, Low 37 Friday – Sunny, High 57, Low 32
FIO: Tomorrow – Mostly cloudy throughout the day. High 54, Low 40 Friday – Partly cloudy overnight. High 63, Low 36
Forecast.io went way warmer than the rest of the group, suggesting faith in model guidance. Makes sense since it is a computer algorithm. I captured the radar much later than I started the forecast, but there is still a bit of light rain in the Arrowhead of Minnesota.
Generally speaking, Tornado Alley is at its most active during the late spring and early summer. The most treacherous tornadoes in Oklahoma’s history have all seem to come in the first week in May, for example. Here in 2019, however, we have been reminded that the so called “Dixie Alley” sees its busiest time in the early part of spring.
We’ve already seen the deadliest tornadoes in 6 years on March 3rd, as a twister in Beauregard, Alabama killed 23 people there alone. Earlier this week, destructive tornadoes rumbled from Franklin and Alto, Texas to Vicksburg, Mississippi.
This pattern is expected to continue in the next couple of days. There is a chance for strong thunderstorms today in the southern Plains, a bit further west than what we have seen so far, but tomorrow poses a risk for a return of severe storms, with an emphasis on tornadoes in Dixie Alley. There is an enhanced risk for severe storms from Louisiana to Georgia and the Panhandle of Florida.
The jet stream hasn’t quite retreated to Canada yet this early in the season, so surface moisture doesn’t build all the way back to the Plains. Cold air is more dense and has more momentum than warm air, so it has no problem intruding on the southeastern US, touching off the strong storms of early spring.
It will get a little bit further away, that cold air, as the summer approaches and finally arrives. The severe threat in the southeast will lessen, but the oppressive heat and humidity will certainly arrive.
We’ll touch upon the storms that have swept through the south, in particular east Texas and the Lower Mississippi Valley soon, but in a less important note, gosh darn it it rained in Hattiesburg on Tuesday morning. It wasn’t much. Nobody noticed it because it was so brief and pre-dawn, but forever on the record it will say it rained on Tuesday April 9th, 2019, and nobody will remember it or acknowledge it, because it was a trace of rain in a week that saw the area get pummeled by more concerted rounds of stormy conditions. on Monday and then again over the weekend. All of these complaints are to say that Victoria-Weather didn’t do greater with the forecast. The National Weather Service and WeatherNation did, however, winning the day. Actual: Tuesday -Trace of rain, High 81, Low 62 Wednesday – High 82, Low 56
Well, we finished this week off with a pretty nasty system in the south central US, and the next few days don’t look any less active. Where will we dispatch from in the next several days?
Duluth, Minnesota Road Trip from Ogden, Utah to Duluth
Texarkana was named after three states it is near. It straddles the Texas-Arkansas border, and isn’t far from Louisiana. Sure, it’s closer to Oklahoma, but Texarklahomana is unwieldy.
At 953PM, CT, Texarkana was reporting a temperature of 59 degrees with clear skies. An oscillating boundary over the region is beginning to pivot back north as an area of low pressure develops over the Big Bend area of Texas. The front had pushed south, associated with a strong system now north of the Great Lakes, but the base of the parent trough is over Texas, and fostering development at the tail of the original front. Texarkana looks to be directly in the line of fire for some strong weather tomorrow. Heavy rain with strong thunderstorms will be possible throughout the day, with the best chance coming in the late morning. Because the activity is expected to arrive so early, Texarkana may avoid a particularly tough fate, which is more likely to the southeast, where a “Moderate Risk” of severe weather is being forecast. The dynamics of the system, particularly the inherent vorticity and widespread instability suggest that this storm could result in a large tornado outbreak. Overcast skies and the chance for light rain will continue through the early morning on Sunday, but clearing skies will arrive by lunch time and continue for the remainder of the weekend. Tomorrow – Rain with strong thunderstorms, High 64, Low 56 Sunday – Scattered showers early, then clearing, High 62, Low 45
TWC: Tomorrow – Variable clouds and becoming windy with strong thunderstorms. Damaging winds, large hail and possibly a tornado with some storms. High 59, Low 56 Sunday – Cloudy skies early, then partly cloudy in the afternoon. High 64, Low 45
AW: Tomorrow – Rain and severe thunderstorms; storms can bring flooding, hail, damaging winds and even a tornado High 64, Low 56 Sunday – Some clouds, then sunshine; breezy and cool High 61, Low 45
NWS: Tomorrow – Showers and thunderstorms. Some storms could be severe, with large hail and damaging winds High 65, Low 56 Sunday – A 20 percent chance of showers before 1pm. Cloudy, then gradually becoming mostly sunny High 62, Low 47
WB: Tomorrow – Showers and thunderstoms. Some thunderstorms may be severe with damaging winds, large hail and tornadoes in the afternoon. High 59, Low 57 Sunday – Mostly cloudy with a 20 percent chance of showers in the morning then partly cloudy in the afternoon, High 61, Low 47
WN: Tomorrow – Cloudy with heavy thunderstorms, High 65, Low 56 Sunday – Partly cloudy with isolated showers, High 62, Low 47
FIO: Tomorrow – Rain starting overnight and windy starting in the morning, continuing until afternoon. High 59, Low 55 Sunday – Mostly cloudy until evening. High 64, Low 45
Here is a look at radar imagery of banded showers across the Ark-La-Tex. Below is a Facebook live event from Todd Warren, a meteorologist out of of NBC in Texarkan/Shreveport looking at the severe threat for tomorrow.
