Hot, Humid. And Mostly Dry.

| 3:36 pm July 22, 2012

Radars are unfortunately quiet across Alabama at this hour.

Temperatures have risen into the lower 90s with a good supply of sunshine.

Heavy showers over Fayette and Walker Counties have dissipated.  Once small shower is trying to get its act together just northeast of Gorgas in southern Walker County. Others are trying to develop south of this down into northeastern Tuscaloosa County.

Elsewhere, there are a few showers over the Tennessee Valley and in Southwest Alabama, but they are of little consequence.

Eye on the Tropics

| 12:19 pm July 22, 2012

Lots of showers and thunderstorms extend from the Bahamas across Cuba. They are associated with a strong tropical wave that is moving northwestward.

The National Hurricane Center says that conditions are not favorable for additional development, but the system is already pretty strong. It will bring strong gusty winds and very heavy rain to Southeast Florida over the next couple of days.

As it moves northwestward into the Gulf early next week, I think it will have to be watched. Wind shear over the system may not be favorable now, but it looks like it will become more favorable over the Gulf.

The position of the Bermuda high would steer the system northwestward toward the Central Gulf Coast. It could arrive there late Tuesday or early Wednesday.

So far, the GFS isn’t picking up on any sort of low-pressure development. The European isn’t hinting at it either, yet. In any case, it could have an impact on the weather for the Gulf Coast and could affect our weather as well, in the form of increased shower and storm chances by midweek if the moisture works northward.

Returning to Daily Summertime Showers

| 6:55 am July 22, 2012

The latest edition of the ABC 33/40 Weather Xtreme Video is available in the player below. You can subscribe to the Weather Xtreme Video on iTunes by clicking here.

The pesky upper low feature once again produced some showers primarily in East Central Mississippi, but some of those showers resulted in an early morning flash flood warning for Sumter County. That upper feature continues to move ever so slowly westward while also weakening. The upper ridge is expected to build into the Southeast US somewhat stronger over the next several days as the Bermuda High and the upper ridge over the western US connect for several days. An upper low moving across southern Canada during the early part of the week will finally result in nudging the upper ridge westward from us allowing another trough to become established over the eastern US by next weekend. This should help to bring temperatures back closer to the 90 degree mark and increase our shower chances and coverage a bit.

So for now, it looks like the heat builds back with highs in the middle 90s for much of the upcoming week. Today will be another temperature forecast challenge thanks to that early morning round of storms. Remember, we are not a one number place so look for most places to get close to 90 while a few spots that remain cloudy stay in the middle or upper 80s. As you might have noted yesterday as seen in the observations from Tuscaloosa, it doesn’t take much sunshine to push the temperature up quickly as their high hit 92 after only an hour or so of sun.

Rainfall amounts will continue to be spotty due to the character of showers and isolated thunderstorms. Severe weather threat is fairly minimal with no widespread severe weather anticipated. Isolated thunderstorms may produce some damaging wind but the threat is more southwest of us in Louisiana with the upper low.

Tropics continue to be quiet in spite of the active start we saw in early June.

The pattern of the trough along the East Coast remains with us in week two keeping us out of extreme heat and in somewhat of an unsettled pattern. While showers don’t hit all spots, they do help to keep drought conditions from worsening significantly.

Don’t forget to listen to our weekly netcast anytime on the web or on iTunes. This is the show all about weather featuring many familiar voices including our meteorologists here at ABC 33/40. You can even listen here on the blog; look for the player on the top left.
