James Spann: Rain moves in late tonight, Tuesday

James Spann has the Alabama forecast for the beginning of the work week from Alabama NewsCenter on Vimeo.

ACTIVE PATTERN: A warm front is now north of Alabama, and the day should be warmer, with most communities enjoying a high in the 60s this afternoon. Colder air over east Alabama thanks to the cold air damming (CAD) effect will be scoured out later in the day. The sky will be mostly cloudy, and showers during the day should be few and far between.

Rain moves into the state late tonight, mainly after midnight, and will continue through Tuesday morning ahead of a surface cold front. Some thunder is possible, but the Storm Prediction Center has removed the marginal risk of severe storms because of the lack of instability. The main window for rain is from roughly 2 a.m. until 2 p.m., and rain amounts of around one-half inch are likely. We start the day Tuesday with temperatures in the 60s, then falling into the 50s during the afternoon.

WEDNESDAY/THURSDAY: Wednesday will be nice day with a good supply of sunshine; we start the day between 30 and 35 degrees, followed by a high between 57 and 60. Thursday will be dry as well; morning sunshine will give way to increasing cloud cover by afternoon. The high Thursday will be in the mid 60s.

MORE RAIN: Rain returns to the state Thursday night into Friday morning; at this point it looks like the main window for rain comes from about midnight Thursday to noon Friday. Thunder is possible, but no severe storms are expected. Rain amounts of around one-half inch are likely. Temperatures will fall back into the 50s Friday afternoon.

THE ALABAMA WEEKEND: Saturday will be dry with a good supply of sunshine; the low early Saturday morning will be close to freezing, but we then rise into the mid 50s by afternoon. Clouds increase Sunday, and a few showers could return by afternoon; Sunday’s high will be in the mid 50s as well.

NEXT WEEK: The active pattern continues; we will have a risk of showers at the beginning of the week, and more rain is likely a few days later. There’s no sign of any excessively cold air for the next seven to 10 days.

ON THIS DATE IN 1983: A major snowstorm impacted the Mid-Atlantic region and southern New England. Snowfall up to 25 inches fell at Allentown, Pennsylvania. Snow amounts of 35 inches occurred in parts of the Blue Ridge Mountains of West Virginia at Glen Cary. Windsor Locks, Connecticut, recorded a record 19 inches in 12 hours. A ship sank off the Virginia/Maryland coast, killing 33.
