Slow moving

As Anthony mentioned in yesterday’s forecast for Cheyenne, there is a huge, hot are of low pressure holding up traffic on the east coast. It’s making things get extremely warm for the the East Coast, and hung things up over the Upper Midwest as well. A boundary that threatened to move through Fargo Saturday night took until early Sunday to expend it’s moisture. The warm air built quickly behind it as a secondary cold front still hasn’t quite made it’s way through Fargo, and things were rather toasty in the city. Accuweather came through with the top forecast, when you realize I transcribed a 69 when I should have put in 59 for their Monday low.
Actuals: Sunday – .24 inches of rain, High 84, Low 63

Cheyenne, Wyoming

Off we go to the capital of the least populous state in the US. For some reason, it’s totally opposite of what Wyoming is best-known for, Yellowstone Park. Perhaps they just like the nightlife in Denver better.

At 7:53PM MDT, the temperature at Cheyenne was 70 degrees under mostly cloudy skies. Most of these clouds were fairly high-based and will dissipate as the evening wears on. An upper-level trough has been very slowly pushing its’ way eastward over the last few days, mainly due to the overpowering ridge that’s parked itself over the eastern US with triple-digit highs. This trough will continue to slowly shift its way through the Northern Plains over the next couple of days as the mega-ridge breaks down somewhere. At the surface, a stationary front has set up shop from ND through northern WY back into ID. This front, however, will turn into a slow-moving cold front as it reluctantly travels towards the southeast. As the front approaches the Central Dakotas down into southeast WY, the base of the trough will be swinging through the Cowboy State as well. This influx of energy could set off some strong to severe thunderstorms around the capital late in the day into the overnight hours. A few lingering showers could last into early Wednesday, with much cooler weather expected as a cooler airmass settles in overhead. While there will still be a chance of some scattered showers/isolated thunderstorms on Wednesday, it’ll be significantly cooler. Gotta love these crazy summer months!

Tuesday: Increasing clouds, possible severe storms in evening/late night. High 78, Low 51.
Wednesday: Scattered showers early, slight chance of a passing shower/storm in afternoon. High 63, Low 49.

TWC: Tuesday: Scattered thunderstorms. High 74, Low 49.
Wednesday: Isolated thunderstorms. High 60, Low 46.

AW: Tuesday: 40% chances of thunderstorms. High 76, Low 51.
Wednesday: Cooler with clouds and sun. High 67, Low 48.

NWS: Tuesday: Severe thunderstorms possible. High 78, Low 52.
Wednesday: Slight chance of showers/storms. High 63, Low 48.

WB: Tuesday: 40% chance of thunderstorms. High 76, Low 52.
Wednesday: Mostly cloudy. High 66, Low 48.

Here we see a deck of clouds off to the north dropping some showers and isolated thunderstorms. These will be dropping southward tomorrow and affect Cheyenne by evening.

Gorgeous Weekend

Given that the 4th of July was on a Sunday this year, this meant lots of people would be out and about hoping to score some nice weather with their holiday weekend. Luckily, for the people of San Jose anyways, Mother Nature pulled through. Mostly clear skies and some breezy afternoon winds pushed temperatures into the mid to upper 80’s. Whatever was perplexing VW and others about the cooler Independence Day came to fruition, as the NWS nabbed the top spot with their cooler 4th of July. Hope everybody had a safe and happy weekend!

Saturday: High 88, Low 56.
Sunday: High 85, Low 56.

Wichita, Kansas

The winner of the 4th of July lottery is Wichita. Everyone in Wichita, stop enjoying the holiday and come read about the weather! Of course, the way thins look, you may be inside already.

At 1207PM, CT, Wichita was reporting heavy rain and a temperature of 75 degrees. Most of their holiday looks to be a washout, as the remnants of Hurricane Alex are continuing to wring themselves out over the central Plains. A cold front associated with low pressure in the Canada was aiding in the continuing onslaught, but will eventually help things dry off. Presently, the last heavy round of rain was just entering Wichita, though most of the activity was training south to north, and the back side is still around Pratt, about 75 miles west. There was a wind shift between Great Bend and Russell that was probably the cold front.
Behind the elongated boundary and the remnants of Alex, an upper level trough and a surface short wave will begin to translate into Kansas. The short wave will induce some surface circulation and trigger even more wet weather Monday. The surface wave will deteriorate by the time it reaches Wichita, and the moisture will be left to wait for the strong upper trough to swing through the region and clear out the unsettled weather, and that won’t happen until late on Tuesday. It will be clearer, however, on Tuesday, so expect a warming trend.

The Weather Channel is going perplexingly chilly. They must be looking for a lot of rain. Speaking of a lot of rain

Fargo, North Dakota

It’s going to be stormy today in Fargo, but what will the next two days bring to North Dakota’s largest city?

At 953AM, CT, Fargo was reporting 86 degrees with mostly sunny skies. A cold front associated with low pressure in Canada was sweeping through the Dakotas and would dictate today’s weather along the Red River. The front was clearly demarcated already at this early hour, with temperatures along the Minnesota border already in the mid 80s, however to the west in Devils Lake and Bismarck, temperatures were only in the 70s with dew points that were also about 10 degrees cooler. Across the river in Moorhead, Minnesota, dew points were in the 70s.
Nothing had been triggered as yet in this juicy, dynamic atmosphere, and the visible satellite gave no hints that anything would happen in the next few hours either. The system has languished in the Pacific Northwest for days, but is now moving much more quickly, and the wet weather should be at it’s in by day break tomorrow. Another trough sweeping through Canada may bring the threat for a sprinkle late on Monday, but attempts at fireworks tomorrow night will be dry and successful.
Tomorrow – Early AM showers, otherwise cooler and pleasant. High 80, Low 64
Monday – Pleasant for most of the day, with a very light bit of drizzle, High 81, Low 59

TWC: Tomorrow – Partly to mostly cloudy (early AM T-Storms). High 84. Low 67

Monday – Mostly sunny, High 82, Low 57

WB: Tomorrow – Partly sunny. A 20 percent chance of showers and thunderstorms in the morning High 81, Low 63
Monday – Partly sunny High 82, Low 57

A look at the visible satellite shows that not much is ready to blow up over eastern North Dakota…. yet.

Surprising chill

That’s a tough title to wrap your head around when, in fact, Jefferson City was in the mid 80s for highs for the past two days. When everyone forecasts highs a few degrees warmer, thanks to the clear skies and southerly flow, it is a little surprising that temperatures don’t get up to the neighborhood we were expecting. Victoria Weather still managed the top forecast.
Actuals: Thursday – High 82, Low 64
Friday – High 86, Low 62

Grade: C

The Week Ahead: 7/4/10-7/10/10

We’ll start on Independence day, then kep on moving through the rest of the week on what promises to be a fairly busy stretch.

Sunday – Wichita, Kansas
Monday – Cheyenne, Wyoming
Wednesday – Winchester, Virginia
Friday – Road Trip from Greenville, North Carolina to Nashville, Tennessee

San Jose, California

Off to the West Coast and the Bay Area for today’s forecast. People don’t know it, but this is one of the three biggest cities in California.

At 853AM, PT, San Jose was reporting a temperature of 62 degrees with a few low clouds. The marine layer was still keeping things murky on the northern and central areas of the Bay, but the southern Bay was already clearing out and will warm up nicely this afternoon.
A trough over the northern Rockies continues to move extremely slowly, and a boundary has moved incrementally over the past several days. It has only been problematic in Montana, where the system is centered, but the flow associated with the low has meant a northwesterly flow off the Pacific. The ridge in the east is rather enormous, and it is not expected to allow the western trough to advance rapidly, and the northerly flow will continue. Expect foggy, cloudy mornings and a sunnier, warmer afternoon.
Tomorrow – Dreary in the morning, then sunny, High 83, Low 56
Sunday – A carbon copy of Saturday, with morning haze and sunny skies later, 87, Low 58

TWC: Tomorrow – High Mainly sunny. High 84, Low 57
Sunday – Sunshine High 88, Low 57

AW: Tomorrow – A full day of sunshine High 83, Low 56
Sunday – Bright and sunny High 88, Low 57

NWS: Tomorrow – Sunny High 88, Low 57
Sunday – Sunny High 85, Low 59

WB: Tomorrow – Sunny. High 86, Low 57
Sunday – Sunny High 84, Low 59

I’m confused as to why the NWS and Weatherbug are going cooler on Sunday. That doesn’t seem right. And of course, Sunday is Independence Day, so it looks like it will be good in San Jose!

June Forecaster of the Month

There was really no competition this month. Well, there was some last minute jockeying for position for numbers 2 through 5, but The Weather Channel simply ran away with things this month. It’s turning into a strong year for our friends in Atlanta.

A breath of fresh air

Sioux City successfully made it through the end of June without any more problems, seeing temperatures in the lower 80s with not a drop of rain to be had. Not a bad way to close out the month, especially the way it had been going. Weatherbug had the top forecast for the city.
Actuals: Tuesday – High 82, Low 53
Wednesday – High 84, Low 56
