Johnson City, Tennessee

We’re headed into the Smokey Mountains and the eastern tip of Tennessee.

At 555PM, ET, Johnson City was reporting clear skies with a temperature of 68 degrees. Weak pressure gradient across the east belied the massive system developing over the High Plains, triggering the first real severe storm outbreak of the season. A warm front is extending into Tennessee is associated with this boundary, but is not developing much by way of precipitation. Even so, the presence of the boundary in Tennessee lends to power of the system in the Plains.
The cause of the system is a cut off upper level low over the western US. The subtropical jet over Mexico will lift north to intercept the low and transport it towards the Tennessee Valley. When the low pushes west it will tap into the Gulf and it’s moisture. The resulting rain and thunderstorms, which will arrive in Johnson City late Friday into Saturday will bring about torrential rains, with 1-2 inches of rain possible to begin the weekend.
Tomorrow – Late rain, High 74, High 51
Saturday – Torrential rain expected in the evening, with thunderstorms possible, High 75, Low 56

TWC: Tomorrow – Showers early then scattered thunderstorms developing later in the day. High 74, Low 50
Saturday – Thundershowers. High 75, Low 55

AW: Tomorrow – Variable cloudiness with a shower High 71, Low 47
Saturday – Mostly cloudy with a shower or thunderstorm around High 74, Low 53

NWS: Tomorrow – A 40 percent chance of showers and thunderstorms. Mostly cloudy High 74, Low 48
Saturday – Showers and thunderstorms likely, mainly after 2pm. Mostly cloudy High 74, Low 55

WB: Tomorrow – Mostly cloudy with scattered showers and thunderstorms High 74, Low 48
Saturday – Cloudy. Scattered showers and thunderstorms in the morning…then showers and thunderstorms likely in the afternoon. Some storms may be severe in the afternoon. Locally heavy rainfall possible in the afternoon. High 75, Low 55

So that’s it. Doom and gloom coming Saturday. Here you can keep an eye on it as it approaches off to the west.

Sunny south Florida

Our forecast for Naples called for some typically active Floridian weather. Fortunately for them, all the thunderstorms that Florida saw the past two days went up inland, away from Naples and then continued to drift off towards Orlando and Lake Okeechobee. Florida thunderstorms are always tough to pinpoint, but it’s never a good idea to beat against them, regardless of what today’s verification suggests. The top forecast went to Weatherbug.
Actuals: Tuesday – High 79, Low 64
Wednesday – High 78, Low 69

Oklahoma City, Oklahoma

A late night forecast for OKC, and we are in the midst of tornado season. How fun!

At 1052PM, CT, Oklahoma City was reporting cloudy skies and a temperature of 55 degrees. A perturbed jet over the Gulf and northern Mexico as generated several somewhat weak disturbances that have swung from the high plains to the Gulf and into the Atlantic. Currently, the next wave is developing over the Oklahoma Panhandle and is generating thunderstorms over northern Texas.
The southerly jet is expected to shift off east, taking support from the thunderstorms over the southern Plains, however this will be motivated by a developing closed upper low over the Rockies. A stationary to warm front will develop through Kansas, indicative of the warm, moist air moving into the Oklahoma City area over the next two days. Showers will not be widespread, but they will be possible in the afternoon each day, with stronger thunderstorms becoming a concern late on Thursday.
Tomorrow – Partly to mostly cloudy, with passing showers and thunderstorm, High 71, Low 51
Thursday – Partly to mostly cloudy, with isolated severe storms before midnight, High 76, Low 59

TWC: Tomorrow – A few showers in the morning with scattered thunderstorms arriving in the afternoon. High 71, Low 54
Thursday – Partly cloudy with a stray thunderstorm. High 76, Low 60

AW: Tomorrow – Mostly cloudy with a shower or thunderstorm around High 74, low 53
Thursday – Mostly cloudy and breezy; an afternoon shower or thunderstorm High 78, Low 60

Naples, Florida

At 12:53pm EDT, the temperature in Naples, Florida was 75 degrees under mostly cloudy skies. A lingering cold/stationary front that’s been found over the Florida Peninsula and along the Gulf Coast has slowly been weakening the last couple of days, but there will still be a decent amount of instability over the region. An ill-defined disturbance over the Lower MS Valley will slowly trek eastward through the Deep South over the next couple of days, enhancing some of the thunderstorm activity farther north over Florida. Tuesday should see a fair amount of activity over the northern 2/3rds of the state especially when the sea breezes converge over the interior part of the state, but Naples could see a few scattered showers still make it down their way. Wednesday sees that aforementioned area of low pressure become a bit better defined towards the Carolinas, giving them a good chance of some stronger thunderstorms during the day. A weak area of high pressure looks to build back over Florida and into the Central Gulf behind this system and keep southern Florida mostly on the dry side, but there will still be a few scattered showers popping up during the afternoon. Overall it should be a good couple of days for beach goers, but Tuesday will definitely be the day to keep an eye on the sky for more scattered activity.

Tuesday: 50% chance of scattered showers/thunderstorm. High 80, Low 62.
Wednesday. 20% chance of a scattered shower, maybe an isolated thunderstorm. High 79, Low 65.

TWC: Tuesday: Mostly sunny. High 80, Low 64.
Wednesday: 30% chance of isolated thunderstorms. High 77, Low 66.

AW: Tuesday: Scattered thunderstorms. High 80, Low 61.
Wednesday: Isolated shower/thundershower possible. High 78, Low 65.

NWS: Tuesday: 20% chance of showers. High 79, Low 64.
Wednesday: 20% chance of showers. High 79, Low 65.

WB: Tuesday: Mostly cloudy. High 79, Low 64.
Wednesday: Partly cloudy. High 79, Low 66.

Some moderate showers are found well off to the north of Naples and off over the Gulf. Some more of these might draw closer tomorrow.

Like day and night

The temperature in Jefferson City fell off a little bit form Wednesday to Thursday. After a balmy 84 degree day on Wednesday, a cold front and it’s associated clouds arrived on Thursday, preventing temperatures from even reaching 70. The Weather Channel and Weatherbug most accurately foresaw this dramatic turn for the worst (if you like hot weather), and ended up with the top forecasts.
Actuals: Wednesday – High 84, Low 54
Thursday – .05 inches of rain, High 68, Low 53

Deja Vu

For the second time this week, we’re going to be verifying a forecast in Bridgeport. Popular place for us this week. I’m just happy we could oblige with a forecast that busted, due to somewhat nicer weather. Clouds were present overnight in Bridgeport which kept lows warmer than expected. On top of that, the showers some called for on Tuesday stayed south of the city. The Weather Channel tied Accuweather atop the leaderboard in this typically Springtime forecast.
Actuals: Tuesday, High 58, Low 46
Wednesday – High 63, Low 41

Jefferson City, Missouri

Our forecast takes us to the capital of Missouri, and a city enjoying some 80 degree weather right now.

At 1153AM, Jefferson City was reporting sunny skies with a temperature of 80 degrees. Positioned squarely in the warm sector of a system moving into the Northern Plains, the area is seeing increased humidity and gusty southerly winds. The Gulf of Mexico is cool so far this Spring, so even though humidity is increased, it isn’t yet oppressive.
The cold front associated with the the area of low pressure over the Northern Plains is well defined, running from western Minnesota to western Kansas, though it isn’t particularly active, with only light showers being seen thus far. The system is rapidly occluding, and an area of high pressure is building over the southeast, cutting off most of the energy in Jefferson City before it can really arrive. As the pattern progresses east, the Gulf will reopen Friday evening with the high pressure shifting out to sea. The boundary will finally sag into Missouri and interact with the new found moisture, with showers and thunderstorms expected Friday evening.
Tomorrow – Mostly sunny and warm, High 78, Low 58
Friday – Afternoon showers and thunderstorms, High 70, Low 55 (non standard)

TWC: Tomorrow – Sunshine and some clouds (PM TStorms). Very warm. High 85, Low 55
Friday – Thundershowers. High 71, Low 59

AW: Tomorrow – Pleasant with intervals of clouds and sunshine High 79, Low 56
Friday – Mainly cloudy with a shower or thunderstorm High 72, Low 55

NWS: Tomorrow – Sunny (PM rain) High 82, Low 56
Friday – A 50 percent chance of showers and thunderstorms. Mostly cloudy High 68, Low 55

WB: Tomorrow – Mostly sunny (PM Rain) High 82, Low 56
Friday – Cooler. Mostly cloudy with a 50 percent chance of showers and thunderstorms High 69, Low 56

Here is a look at the satellite, showing that cold front very well over the Northern Plains.

Protected by mountains

Anchorage looked to be in line for a rather nasty couple of days, however the elevation around the Cook Inlet kept all that nasty weather out of the city. In the end, they ended up with only a bit of rain overnight from Monday to Tuesday, and cloudy skies all around. Victoria-Weather ended up with the top forecast, and I couldn’t be prouder.
Actuals: Monday – Rain observed, but not measured, High 45, low 39
Tuesday – Rain observed but not measured, High 44, Low 36

Bridgeport, Connecticut

Back to Bridgeport on this fine Monday evening. Let’s rock and roll!

At 1152PM, ET, Bridgeport was reporting a temperature of 53 degrees with clear skies. A long boundary ranged from the central Rockies and tailed off as it swept into the Mid Atlantic. Later tonight, showers should develop along this boundary as an area of low pressure over the Rockies shifts into the high plains.
Models have been universally poor for the past week or so, however the basics are still valid. The extended stationary front south of the area will dissipate over the coming days, with a Canadian ridge shifting into New England. Some showers are a remote possibility Tuesday morning, though clearing is expected to move in by midweek.
Tomorrow – Scattered showers in the morning, then clearing. High 59, Low 41
Wednesday – Partly cloudy, High 64, Low 43

TWC: Tomorrow – Cloudy skies. High 58, Low 40
Wednesday – Mainly sunny. High 62, Low 39

AW: Tomorrow – Times of clouds and sun High 56, Low 42
Wednesday – Mostly sunny High 61, Low 42

NWS: Tomorrow – A chance of sprinkles after 1pm. Mostly cloudy High 57, Low 38
Wednesday – Sunny, High 65, Low 39

WB: Tomorrow – Mostly cloudy with a chance of sprinkles High 57, Low 38
Wednesday – Sunny. High 65, Low 39

A look at the satellite shows that long stream of clouds headed towards Bridgeport. Good times to be had by all.

Way too dry

I had mentioned that Youngstown was going to see an area of high pressure stanch the flow of moisture from the Gulf of Mexico north to their neck of the woods. As it so happens, this had a greater influence on the forecast than I had originally prognosticated. The low temperatures, unchecked by moisture on Saturday, plummeted to the upper 20s, and the cold front passed through yesterday completely dry. In the end, there was a three way tie at the top, between Accuweather, the Weather Service and Weather Bug.
Actuals: Saturday – High 63, Low 28
Sunday – High 66, Low 42
