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

Jefferson City, Missouri

And we’re off to central Missouri for the forecast on this beautiful Wednesday.

At 1053AM, CT, Jefferson City was reporting a temperature of 75 degrees with clear skies. Hurricane Alex and a cold front were interacting to keep showers and thunderstorms south of at least Memphis. High pressure over the northern US was able to build south into the area.
That high pressure will dominate for the next two days. The city will be at the back edge of the ridge, which will mean a southerly flow and warming temperatures through the end of the week.
Tomorrow – Sunny, High 84, Low 59

Beautiful weather for the capitol city to end the week and to kick off the holiday weekend.

Cuba

Today’s trip around the world takes us to our nation’s nearest maritime neighbor, Cuba, which of course lies less than 100 miles south of the Florida Keys. Like many nations in the tropics, Cuba sees a seasonal variation in their thunderstorm activity based on the flow of the ITCZ. This is their rainy season, which also happens to correlate with hurricane season. Ah, the hurricanes. Cuba’s position at the mouth of the Gulf of Mexico and at the end of the Atlantic Basin path that most hurricanes take when they develop off the coast of Africa means that the island is frequently ravaged by tropical storms. It’s actually rare that the residents of Cuba don’t get hit by a hurricane at least once a summer. When they aren’t fending off hurricanes, the easterly trades of summer make Cuba an active island for thunderstorms, thanks again to it’s elongated position, perfectly oriented to intercept those winds, and have the elevation and required moisture to make every afternoon an adventure in thunderstorm dodging, particularly in the middle of the main island.
The Cubans have been scorned by much of the western world because of their dictator Fidel Castro and his communist state, however in an effort to get back in the good graces of the rest of the world and perhaps show his effective leadership (or something) Castro has sunk a lot of money into the sciences, most notably medical training and research. It should be no surprise, then, that the Instituto de Meteorologia appears to be relatively well funded. Most nations don’t have their own satellites or models from which to grab data, and the often pull from the United State’s ample resources, so given the current frosty relations between our nations, I was curious to see where they got their satellite data from. Sure enough, NASA, The University of Wisconsin and Intellicast, of all things. Under the Pronostico tab, the “para hoy” you will find today’s forecast. An interesting feature is that they show the picture of their forecasters which provides a little accountability, I suppose. Speaking of accountability, the entire roster of the Cuban Meteorology Service lists their e-mail address. Usually, I would e-mail the weather service to find out more about them, or at least inform them of the post. That said, I have personal experience forecasting for Cuba so I know I am mostly accurate on the details, and I don’t care to get flagged permanently by the FBI, so if you want to know more about the Cubans, by all means, e-mail away.

We have a hurricane (almost)

Tropical Storm Alex is churning in the Bay of Campeche and now appears destined to make landfall south of the Rio Grande, but near enough to the US that it will certainly cause some consternation. This system has been incredibly difficult to get a bead on. Early in it’s life cycle, it appeared as though the system would split the gap between the western tip of Cuba and the northern reach of the Yucatan, which would have allowed the storm to intensify rapidly before making a land fall somewhere in the eastern Gulf Coast.
Next, after model guidance had a better handle on it’s directionality, there were questions about how the storm would hold together as it crossed the Yucatan. It appeared that he would be able to maintain enough circulation that he wouldn’t send too much thunderstorm activity north into the central Gulf Coast. Well, Alex tracked over Belize and the southern, wider part of the Yucatan and was almost pulled apart. Now weakened, it appeared Alex would trudge slowly across the southern Bay of Campeche and make landfall as a weak hurricane at most, if it was able to get organized.
Well, now it has taken a northerly turn and is taking its time across the Gulf, getting stronger and better organized as he goes. Right now, it seems as though he will make his landfall late Wednesday night or tomorrow morning. The way it’s gone so far, however, I wouldn’t be surprised to see his track shift a little bit further north and into Brownsville. Here is the official track at this time.

Too many storms

I suspected that Cleveland may be in good shape over the forecast period, avoiding any real severe weather due to the timing of the thunderstorms. Well, instead the storms came through in the middle of the day on Sunday and left a swath of damage in the Cleveland metro. There was a small tornado up in Ashtabula, but most of the damage was the result of straight line winds. The airport in Cleveland reported winds of over 40mph in the early evening. The Weather Channel, as seems to be usual lately, had the top forecast.
Actuals: Sunday – .21 inches of rain in thunderstorms, High 93, Low 73
Monday – .02 inches of rain, High 82, Low 73

Morristown, Tennessee to Sioux City, Iowa

Remember how much fun we had yesterday with the day long road trip? Well, let’s try to double the fun with a two day trip from Tennessee to Iowa. It’s going to cover 1034 of the flattest miles you may ever see. All that travel will be done at a pace of 62.8mph, and we will get to shy of half way after the first day, covering a mere 502 miles. I’m ready. Are you?

DAY ONE

The day may start a little slow for a variety of reasons. First, it will take an hour or so to get from Morristown to the interstate in Corbin, Kentucky were we can really start to drive. Second, the back side of a system moving through tonight may leave some memories in the form of some early morning showers for the Smokeys. By the time we are on the interstate, however, we will be able to drive quickly free of lingering showers and restrictive speed limits. We will end the day in Mansfield, Illinois, between Urbana and Bloomington.

DAY TWO
Day two, Wednesday, will be a very easy drive. The interstates are good, the roads curve every once in a while to keep you engaged. Other than that do, it’s a good day for a road trip, with sunny skies and warming temperatures. Roll the window down and enjoy the open road on our way into beautiful Sioux City.

Sioux City, Iowa

Sioux City has been getting raked over the coals the past few days, but finally it appears they are clearing out, ready to enjoy some much better weather.

At 152PM, CT, Sioux City was reporting a temperature of 82 degrees with clear skies. A long, low amplitude ridge was shifting into the center of the country. It wasn’t inhibiting much because of it’s strength, but there was little at the surface to kick up showers or storms.
The presence of Tropical Storm Alex in the Bay of Campeche will also aid in capping any thunderstorm development for the next several days by redirecting Gulf moisture away from the typical corridor up the Mississippi. A weak trough will begin to move in late on Wednesday, however it will only serve to knock down temperatures by a couple degrees and kick up some winds as there will be no moisture to work with.

It’s certainly going to be a relief for residents of Siouxland not to have to deal with another torrential downpour tonight. A look at the satellite tells that, in fact, it is quiet in Sioux City.
