Summertime rages on

This summer has been incredibly warm for most of the country. The West Coast doesn’t know it, but 5/6ths of the country is steeped in uncomfortably warm conditions. This is a result of a jet that has stayed fairly well defined and north of the Canadian border. Southerly flow and no infusions of cooler air from an occasional trough have allowed the country to bake. But at least there is the southerly flow which is introducing a great deal of humidity which, while making things stuffy, is preventing temperatures from climbing any further for the Mississippi Valley or points to the southeast. Of course, where the humidity doesn’t climb, in the Plains and in the deserts, temperatures ARE pinging in at triple digits. Pretty tough on the air conditioning bill.

Perfect weather

Well, it is for me at least. It may have been a little too hot and humid for most in Louisville for the past few days with highs in the 90s and dew points high enough for it to be muggy. I like that, I can understand if you might not. Anyways, the top forecasts, good ones at that, went to V-W and The Weather Channel

Greenville, South Carolina to Tallahassee, Florida

Our Monday afternoon drive will be fairly enjoyable. It’s only about 7 hours from Greenville to Tallahassee, covering 414 miles. That puts us on a pace of 59.7mph, thanks in large part to some country roads and a trip through the heart of Atlanta.

For a drive through the southeast in the dead of summer, this will be a fairly easy trip. A low off the Florida coast will pass over the Peninsula and draw almost all focus for thunderstorms south of our route. It’s going to be so blasted hot and humid for the drive that there is that outside chance of a storm, but that likely won’t come until after we have been on the road for a while. I would say we will be dry until we reach Macon, after which we will fend off some isolated showers until we hit the Florida border. No rain is expected in Tallahassee, but it will be incredibly warm.

Tallahassee, Florida

We’re forecasting for the capital of Florida. Fun fact, it’s actually warmer here in Minneapolis than it is in Tallahassee.

At 653PM, ET, Tallahassee was reporting a temperature of 91 degrees with clear skies. A mostly stationary boundary has existed along a line from southern Arkansas towards Tampa for most of the day, and is continuing to touch of thunderstorms off the coast south of Tallahassee and to the west, generally west of Panama City.
An area of low pressure east of the Florida Peninsula will traverse the Peninsula into the Gulf of Mexico over the next couple 18 hours or so and will lie south of Tallahassee by tomorrow. Fortunately, this will put Tallahassee in a perfect position, with flow becoming off shore, deadening the threat for showers and storms. The system, which does have a slight chance of becoming a tropical storm, will stay well south of Tallahassee as it passes through the Gulf, which will allow the Floridian capital a rare 48 hours of dry air.

I’m a little cooler than the rest. Humidity and noth winds should keep temperatures from climbing too terribly high. The radar shows thunderstorms off to the west.

Greenville, South Carolina

Up into the Piedmont to end out week today.

At 1153AM, ET, Greenville was reporting a temperature of 84 degrees with clear skies. A persistent boundary, borne both of a weak surface low just off the coast and the moisture of the Gulf of Mexico sat just south of the Greenville-Spartanburg area and was generating some clouds along the Georgia border and keeping dew points a little bit lower than sites touth of the boundary.
The weak system will actually do enough to keep moisture south of Greenville for today. The effect of Tropical Storm Colin in the western Atlantic will actually assist in shifting the boundary south, further away from Greenville, but the absence of an east-westboundary will allow for a weak north-south wave to ripple into the Piedmont and bring the threat for an isolated thunderstorm Monday afternoon.

Wow, not often Weatherbug and the Weather Service have different precipitation forecast. Here is the latest satellite.

A lucky few degrees

It’s a dangerous thing, trusting the models unquestioningly. In mountainous locations, I wouldn’t dare try to divine the temperatures out west without the raw numbers given by models, but I noticed that in Wenatchee, the models had been trending cooler for the past several days, so I reflected that in my forecast. Sure enough, Victoria-Weather had the best forecast. It was only better by a degree or two every day, but that eventually added up to an easy win.

Feature Forecast: Jon Slater, Fox 25 News, Oklahoma City, Oklahoma

Surprise! We have a very special guest, Jon Slater from Oklahoma City, weather capital of the world who has been kind enough to give us a hand with a two day forecast for his home city. Without further ado, here is Mr. Slater!

I’m Jon Slater the meteorologist for FOX 25 News @9 and 10pm in Oklahoma City. I’m a weather fanatic and have been my entire life! Growing up near New York City I developed a passion for the weather at a very early age. I spent most of my childhood watching the weather out my bedroom window. My parents thought I was crazy! By the time I was a freshman in High School I new I wanted to study the weather and become a meteorologist. Went to the University of Oklahoma to get my degree in meteorology because the school is located smack dab in the middle of Tornado Alley. After graduation in 1987 I decided to try TV weather and 23 years later I’m still doing this stuff.

Here’s the forecast for OKC….

After 5 days in a row of 100 or hotter weather a weak Summer cold front is moving in tonight. Expect a few scattered t’storms with a low near 77 and winds becoming light and variable.

On Thursday a very small break in the high heat. Partly cloudy with a 30% chance of t’storms highs near 95 with a north wind at 10 mph. Yes, 95 is a cool down for us!

Then the extreme heat comes right back for Friday with sunny skies and highs near 98.

Over the weekend look for sizzlin sunshine with highs near 101 both Saturday and Sunday. The heat wave continues all next week too!

Stay cool, Jon

Thanks Jon! It’s always interesting to hear the perspective of another meteorologist. I wonder how hard it would have been to get a hold of him during May?

(Thursday’s scheduled forecast for Louisville will be moved to Friday)

Wenatchee, Washington

I had to look up Wenatchee when doing this forecast too. It’s nestled into the eastern slope of the Cascades, if you are ever told you need to go to Wenatchee.

At 955AM, PT, Wenatchee was reporting a temperature of 73 degrees with clear skies. Warm temperatures and a rash of thunderstorms in the Cascades has led to flash flood was being issued for the area. There is a weak upper level trough in the area, though with no jet support it appeared as though it would not be able to develop anything at the surface. Expect mostly sunny conditions for Wenatchee each of the next two days.
Tomorrow – Sunny, High 94, Low 62
Friday – Sunny, High 91, Low 65

TWC: Tomorrow Sunny, along with a few afternoon clouds. Hot. High 95, Low 67
Friday – Sunshine. High 92, Low 66

AW: Tomorrow – Partly sunny and hot High 93, Low 65
Friday – Sunny High 91, Low 65

NWS: Tomorrow – A 20 percent chance of showers and thunderstorms. Mostly sunny and hot, High 96, Low 65
Friday – Mostly sunny High 93, Low 65

WB: Tomorrow – Partly sunny, a slight chance of showers and thunderstorms in the morning, then a chance of rain showers and slight chance of thunderstorms in the afternoon, High 97, Low 64
Friday – Mostly Sunny, High 93, Low 64

Weatherbug sure had a lot to say there, didn’t they? A look at the satellite shows some puffs over the Cascades that are likely producing a bit of rain.

The definition of isolated

For Monday, everyone had the threat for thunderstorms in their forecast for Bismarck. I had even mentioned that they would be isolated in my forecast. On Monday evening, one cell popped up northwest of Bismarck, taking with it a tornado warning and rolled right through North Dakota’s capital. There were 40mph winds at the airport, and the city received a quick quarter inch of rain. The forecasts were tightly clustered, but The Weather Channel nosed the rest of us.
Actuals: Monday – .25 inches of rain in a heavy thunderstorm, High 86, Low 65
Tuesday – High 83, Low 62
