Frost Likely Early Thursday

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

THIS AFTERNOON: Our weather doesn’t get much better. A cloudless sky, low humidity, and temperatures in the 70s. A delightful spring day in Alabama.

Tomorrow we stay dry, but high clouds will show up due to showers that will be as close as Mississippi, Louisiana, and Arkansas. We will call it partly sunny with a high in the upper 70s.

COOL CHANGE: The weather turns much cooler Wednesday as a long wave upper trough forms over the eastern U.S. We probably won’t make it out of the 60s Wednesday with a cool breeze, and the stage is set for a frost threat for much of North and Central Alabama at daybreak Thursday.

Looks like lows early Thursday will be generally between 32 and 39. The colder valleys of Northeast Alabama will have the chance of a light freeze, with frost potential elsewhere, especially in the low spots and protected areas. The ridges will most likely escape frost up in the inversion layer, generally about 500 feet and higher.

It is likely that a frost advisory will be issued for late Wednesday night and early Thursday, and growers will need to protect anything that might be harmed by frost. This will be our last frost threat until sometime this fall, probably in late October or early November.

FRIDAY AND THE WEEKEND: Friday promises to be a beautiful day with ample sunshine and a high well into the 70s, maybe around 80 over West Alabama as we warm up quickly.

Over the weekend, we will be in a battle zone between a warm, dry upper ridge to the east, and a stalled surface front to the west. I think Saturday will be warm and dry with a partly sunny sky and a high near 80 degrees, but we just might have to mention some risk of a shower Sunday and Monday, mainly over the western third of the state. We stay warm with a high around 80 degrees both days.

LONG RANGE: The 12Z GFS shows some thunderstorm risk here around April 19, but this feature comes and goes, and generally speaking we don’t see any major severe weather threat here for the next two weeks. See the Weather Xtreme video for more long range ideas and details.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute 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. We will record this week’s episode tonight at 8:30 p.m. CDT… you can listen live via uStream here.
