APRIL COLD SNAP: This is why we have been cautioning people not to get out in the garden for planting just yet. We almost always have a late season cold snap here in Alabama, and the time has come.

Cold air advection is the story today; clouds, strong north winds, and temperatures holding in the 40s much of the day. There could be a little drizzle at times over the northern third of the state as energy rotates through the long wave upper trough over the eastern U.S.; you might even hear of a few snow flurries over the Tennessee Valley tonight or tomorrow. But, the cold is the big story.

HOW LOW? Tomorrow morning will feature a low very close to 30 degrees, and that should be pretty uniform thanks to clouds and wind. Tomorrow morning, the ridges will be colder. But, just the opposite on Wednesday morning as the sky will be clear and the wind light. We figure most places will be in the 27 to 30 degree range early Wednesday, but the spread will probably be from 20 in the coldest valleys to 35 on the ridge tops. The bottom line is that growers will need to prepare for two mornings with the potential for a freeze statewide; the coldest morning for many places, most likely, will be Wednesday morning.

LATER IN THE WEEK: A warming trend begins Wednesday afternoon as we rise into the 60s, and 70s are likely Thursday. Our next chance of showers and storms will come late Thursday night and Friday; for now the severe weather risk looks fairly marginal, but we always have to watch any storm system that blows through here this time of the year.

WEEKEND PEEK: For now the weekend looks nice, with a sunny sky Saturday and Sunday along with highs in the 70s. Showers and storms will return Monday of next week.
