Another Chantal to forget

Tropical Storm names recycle every 6 years, unless they are retired. The powers that be update their lists every once in a great while, but Chantal has been a part of the lists since 1983, a solid 36 years, and six total cycles. Once, in 1989, a Chantal emerged in the Gulf and began dissipating as she hit the Texas Coast. That was the last time we have seen a Chantal of any significance.

2003’s Chantal was as close as we’ve come to remembering any Chantals, with $5mm of damage to the coastline of Belize. All told, given the scope of damage a hurricane can introduce, that’s pretty much coming away Scot free.

But it’s still more than most Chantals can say, including the one that just formed in the way north Atlantic over the last 48 hours. Check out the current satellite imagery of the storm.

Not only is Chantal disorganized, but the closest island is Newfoundland. This Chantal is going to be just as uneventful as previous iterations.

After a busy couple of years, not only is Chantal harmlessly out to sea, she is also the first storm in months. Granted, we are approaching the peak of the season, but there isn’t any development looming quite yet. With any luck, this entire hurricane season is one big Chantal.

Providence, Rhode Island to San Antonio, Texas

We are going to head right into the heat here in the dog days of summer. There will be a point where we have to pass through some storms to get from moderately more tranquil weather in New England to the steamy south, but where will it happen along our 2013 mile journey? And when, over the 4 day trek? As you might be able to establish, we will cover a bit more than 500 miles a day (519, actually) while traveling at a pace just shy of 65mph, which is somewhat slow, thanks to the tangled web of the east coast, and not a fear of impending thunderstorms.

Providence, Rhode Island

DAY ONE (Tuesday)
Naturally, the feature first expected to impact our journey will be a weak shortwave trough moving out of the Great Lakes. Why is this great? Because I’m being sarcastic, and this will be difficult to forecast around. There is consensus that we will be dry through the New York City area, but then it becomes a little dodgier. I think the model that brings a lot of rain to Pennsylvania is doing so because of poor resolution. I think it’s going to generally be mostly cloudy with some isolated spots of rain, but maybe not enough to even turn the wipers on. These dots will be possible for the rest of the journey, though becoming less likely as we pass into Virginia. The day will end in New Market, Virginia, in the northern part of the state.

DAY TWO (Wednesday)
Another wave moving into the Great Lakes is going to carry with it a bit more weight. Inflow towards the low might lead to some fog and haze in the Appalachians and Smokey Mountains, but the potential for heavy thunderstorms will arise in Tennessee. Not widespread, destructive thunderstorms, mind you, but isolated, pop up showers and storms of questionable coverage. The strongest storms will stay west of the Appalachians, and coverage will begin to wane as a strong batch of storms erupts over northern Missouri late in the afternoon. We’ll make it to Reece City, Alabama, northeast of Gadsden.

DAY THREE (Thursday)
I’m not in the market for going out on an island to predict tropical storms, but I will say, there looks like a week area of low pressure developing over the western Gulf through the middle of the week. Alabama will stay dry on Thursday morning, but some scattered showers will pop up fairly early in Mississippi, and we should be soaked through southern Louisiana. Thunderstorms are likely, but I would be surprised if any of this activity is severe. We’ll stop just west of Lafayette, in Scott, Louisiana.

DAY FOUR (Friday)
That at times steady rain, with a few embedded thunderstorms, will continue through western Louisiana, and may even remain a concern as deep into Texas as Houston, but after we reach the western suburbs, I think we are in the clear. Just in time for more oppressive heat! At least there will be a few clouds every here and there, but not enough to make things feel significantly diffeent in San Antonio than they did in Providence.

San Antonio, Texas

San Antonio, Texas

Let’s take a look at the southern part of Texas, where it’s going to be extra hot and extra sticky.

At 751PM, San Antonio was reporting a temperature of 94 with a dew point of 70. Clear skies covered eastern and downstate Texas, though the dry line was active on satellite in the western part of the state. Excessive heat advisories continue through the southern Plains, as high pressure has settled into the area.
The anticyclonic flow is going to dissipate over the next 48 hours, with a return flow setting up along the Sabine River but not any further to the west. San Antonio looks to remain dry if uncomfortably warm to begin the workweek.
Tomorrow – Mostly sunny, High 99, Low 78
Tuesday – Still hot, High 99, Low 79

TWC: Tomorrow – Partly cloudy skies High 99, Low 78
Tuesday – A few clouds from time to time. Continued very hot. High 99, Low 78

AW: Tomorrow – Mostly sunny; very warm High 100, Low 79
Tuesday – Mostly sunny; very warm High 101, Low 78

NWS: Tomorrow – Mostly sunny and hot, High 100, Low 79
Tuesday – Mostly sunny and hot, High 100, Low 78

WB: Tomorrow – Mostly cloudy in the morning, then clearing. High 98, Low 79
Tuesday – Partly cloudy. High 97, Low 78

WN: Tomorrow – Partly cloudy, High 100, Low 79
Tuesday – Partly cloudy, High 100, Low 78

FIO: Tomorrow – Humid and partly cloudy throughout the day. High 98, Low 79
Tuesday – Humid and partly cloudy throughout the day. High 99, Low 78

Here is the satellite, with some puffs developing in west Texas.

Colorado sees it’s largest hailstone ever

Last night, massive supercells cropped up in the eastern plains of Colorado. A few tornadoes were reported, though there isn’t much population to really see much of a threat. The hail was more widespread, however, and it was gigantic.

Take a look at the tweeted imge of Colorado’s new largest recorded ahi slone.

The crazy part is that pattern didn’t change much, if at all. Tennis balls fell on the same location the very next night!

Hail stones are caused by strong updrafts, which cause droplets to accrete more and more ice and causes it to become heavier and heavier. The hail stone falls to earth when its weight causes the downward gravitational force to exceed the updraft force. Storms in eastern Colorado have had such intense updrafts so as a half a pound of ice could be suspended. These storms were fueled by the clash of dry air from the west intersecting the heat and humidity in the High Plains.

You can read more about the hail at the Denver Post.

Some good news this summer

After several consecutive years of drier than normal conditions, and severe drought and water shortages across California, a robust winter and a long spring have nearly reversed the trend, save for a slightly dry patch over the San Diego area.

Additionally, it doesn’t appear as though the drought will return even late this summer. A break is just what all concerned parties need this summer. Hopefully, it will persist next year as well.

PDS Severe Thunderstorm watch issued for northern Kansas

A watch is issued when a dangerous situation is possible, but a PDS, or “particularly dangerous situation” watch indicates a level of certainty for high end severe weather that should give residents within the bounds of a watch pause. The SPC has issued a PDS Severe thunderstorm watch for Northern Kansas and parts of southern Nebraska, including Lincoln.

Usually, PDS watches are for tornadoes, when supercells are expected to produce large, long lived tornadoes. In the case of this severe watch, that massive line bearing down on Hill City, and ultimately posing a threat for Concordia before dawn, the ongoing threat will be extremely violent straight line winds.

The text of the watch includes a threat for winds of 85mph or greater, while there have already been reports of gusts to 80mph as the squall exited Colorado. This storm is going to rage overnight, which means it will likely take many people off guard. Unlike tornadoes which usually bring sirens, but ultimately pick and choose their way across the countryside, this storm will not trigger warning sirens in every county, despite the risks, and will likely impact more residents. The PDS attribution should make all emergency personnel in the area take notice and be ready to respond as necessary.

It’s going to be a noisy night.

Tropical season is underway in the Pacific

At the time of the GIF The Weather Channel tweeted out, Super Typhoon Lekima was a category 4 storm, doing a quick two-step around Tarama Island southwest of Okinawa. Lekima was one of two typhoons spinning in the region at the time, but fortunately, Lekima was ultimately the only one that made its way to the mainland, striking south of Shanghai.

Krosa ultimately flamed out, but Lekima did lead to 30 deaths, most of which came in a landslide in the populous and hilly Chinese coastal regions. The remnants of the storm are still moving up the coast, and though it no longer maintains the same levels of intensity, the heavy rains are going to continue to bring problems to many communities.

While Lekima was fierce and scarier still when in tandem with Krosa looming on the horizon, we are in a surprisingly calm period, given the time of the year. The Pacific is generally faster to start tropical season than the Atlantic (which remains remarkably dormant) but aside from Lekima and Krosa, there are no other named storms on the planet.

The Eastern Pacific looks next to give rise to another storm, as models seem to hint at something popping up in the next 10 days, but the Eastern Pacific is usually one of the safer places for tropical development, interception with land is rather difficult.

It’s still a month from the peak of the Atlantic season, and the Pacific Season can often come in waves, but through the middle of August, we look to be n a welcome pause this tropical season, especially in eastern China, where recovery is needed.

Coming soon…

We are getting into the late part of summer, and we start to forget about severe weather (major outbreaks, anyways) and start really focusing on the Tropics. With a light forecasting load, we’ll really be able to dig into the potential storm activity around the world, should it arise.

July Forecaster of the Month

Summer time in the forecasting world can be fairly sporadic, and won and lost on the margins, especially if you don’t take into account the tropical season, which has been, this year, fairly dormant. Those margins, though, can be pretty important, particularly in the energy sector, where temperature forecasting becomes crucial, and every degree matters. It may not seem as important to the lay person, but this win for Accuweather, is just as important as any other month.
