Welcome to DST!

"DST" being daylight saving time, which I loathe, as it means my workday is an hour longer (no the computer models do not run an hour earlier to compensate for the time change). But alas, I won't rant too much about that minor inconvenience here!


Although there isn't much in the way of extreme weather to talk about in the near term, with the exception of the possible blizzard in the northern Plains in the next couple of days, we do still have some things to watch for. First is the chance for isolated severe weather in the Midwest the next couple of days, but it doesn't look like a big event, so I won't talk much about that. I will turn more toward severe weather though as larger threats come down the road, so stay tuned for that. I showed in my last post the big temperature contrast from the warm side of this week's front to the cold side, and it does still look like quite a reversal later this week, starting in the Plains / Midwest and spreading east. I also said I was watching a southern stream feature in case it can produce any wintry mischief (or fun, depending on your perspective) this weekend, and this is still on the table. Sure, it is a long shot, but somewhere from the Apps of the Virginias into the Northeast could see something out of it given the cold in place, if the feature can come far enough north. Most recent GFS run says to at least keep an eye out.

Yes, the GFS 6.5 days from now is not the most reliable, but hey, I said it's a long shot, and it is (though not impossible), but at this point is all we have to really watch in the eastern U.S.

Turning to my own backyard, I'm torn on this weekend. I have outdoor plans for the first time in awhile, and wouldn't you know it, it looks rainy, which hardly ever happens down here anymore. To make matters worse, it looks quite chilly for this time of year too. Some of the cold air coming out of Canada gets down here later this week, and at the same time, the southern stream feature in the Southwest (same one to watch in the east toward the weekend) comes out, and moisture "overruns" the cooler air at the surface. Typically, a southwesterly flow bring in warmer air, but in this case clouds and rain effectively trap cooler air in the low levels. Below is the GFS model's idea for Saturday afternoon. Yes that is 40s shown for most of Texas even in the afternoon, with the chilly rain to go with it. Yuck. This model may be overdoing the cool air, but right now I tend to think much of Saturday is spent no warmer than low / mid 50s down here. Good news is we need the rain badly, though I'd like it to wait a couple of days longer.
