Showers But Seasonal

Clouds increased overnight with showers expected to affect our area later this morning and into the afternoon. Not everyone will see rain, and even if you are lucky enough to get a shower, rainfall amounts are not likely to be that great. Most spots will see less than a quarter of an inch. Showers diminish tonight with the weather improving on Sunday as the upper trough axis goes by during the day. This will pave the way for an upper ridge to move into the Southeast US while another strong closed low moves into Texas out of the Southwest US by Wednesday.

This next system certainly shows some potential for both a significant rain producer as well as severe weather. The Storm Prediction Center is not specifying a particular area for severe weather for a number of reasons. One of the biggest reasons concerns the huge model differences we’re seeing that far out. However, it seems that with the 06Z GFS model run and the 00Z European model run that the two models are converging on a similar solution. There are still some fairly substantial differences in the two models, however, they do present a closer look than what we’ve been seeing for the last couple of days.

The GFS is suggesting that 65-degree dew points will surge northward to the Birmingham area. CAPE values off the GFS are also into the 300 to 500 range which are more than sufficient for severe storms. So we’ll have to watch how this next system develops as we get closer to the event.

Once that system zip by us on Friday, we come back under a ridge with a continuation of a southwesterly flow pattern aloft. This again will keep us in a rather mild pattern with highs climbing into the 60s for the end of the week and the weekend.

Yet another deep trough comes out of the Southwest US on Sunday according to the GFS which poses another round of wet weather for us. Looking further into voodoo country, another wet system comes along around the 17th with a very cold look to the pattern on the 19th with a deep long wave trough over the eastern half of the country. We’ll see!!
