A Few Passing Showers Through the Day; Rain Returns for the Latter Half of the Work Week

| March 10, 2019 @ 7:01 am

I hope that you remembered to set your clock ahead when you went to bed last night. If not, your alarm might have been off by an hour when it awakened you this morning, and you might be late! Daylight Saving Time began a 2 a.m. local time this morning, for better or for worse.

DODGED ANOTHER BULLET: Well, we dodged another bullet severe weather wise across Alabama last night, with no significant issues. While shear values were very high, instability and moisture levels were borderline and low-level lapse rates were just too weak. Our next issues come on Thursday of this week, with another marginal severe threat, but more in the way of a heavy rain threat. Let’s dig into the details.

COOL FRONT PUSHING SOUTH: The frontal system slowed overnight as it became parallel to the upper-level flow. A few showers are lingering this morning across the area. They will gradually end north of I-20 by noon but could linger in places like Demopolis, Clanton, and Roanoke through the afternoon. In fact, they could increase by late afternoon and into the early evening as a passing upper-level disturbance slides by to the north. Highs this afternoon will be generally in the upper 60s to lower 70s. Lows tonight will be in the 40s north of US-278, with 50s elsewhere.

NEW WORK WEEK: Tomorrow will be slightly cooler, but still very close to average readings for this time in March. Expect a few showers over the south as a passing short wave disturbance stirs things up a bit. Highs will be in the middle and upper 60s. Lows will be in the 40s. Tuesday will feature partly sunny skies and highs in the upper 60s. It will be dry, but a strong southerly flow ahead of our next storm system will start bringing warm, moist air northward.

MIDWEEK MOISTURE: Those moistures will skyrocket by Wednesday. As strong warm air advection continues during the day, a few showers will show up by late afternoon and heavy rain and thunder will increase overnight. Wednesday highs will be in the 70s.
THURSDAY: Rain and storms will become likely on Thursday. Precipitable water values will rise to near 2 inches, which is 200-250% above normal. There will be some instability, with CAPE values between 600-1,000 joules/kg2. Dewpoints will rise to near 65F. This will set the stage for heavy rain. The rain will continue through the night but will start slowly easing southeastward on Friday. Thursday highs will be in the 70s, but will fall back into the upper 60s by Friday.

WEEKEND: The weekend will feature a change to colder behind a cold front. Lows Saturday morning will be in the 30s and 40s. Highs on Saturday will be in the 40s over North Alabama with 50s over the rest of the area. Sunday will be sunny and cool, with morning lows in the 30s and after readings in the 50s.

RAINFALL TOTALS: The GFS is predicting over 2 inches of rain for all areas along and north of I-59. Over 5 inches will fall over northwestern Alabama.

GULF COAST WEATHER: A nice week overall along the beautiful beaches of Alabama and Northwest Florida, especially in the temperature department. Highs will be I the 70s each day through Saturday. Lows will be in the 60s. Rain will be a part of the forecast through Monday, with a brief respite on Tuesday before more rain and storms arrive at midweek. The best chance for rain will be on Friday into Saturday morning.

ON THIS DATE IN 1996: Destructive cold temperatures occurred across Alabama and Georgia. The cold affected fruit crops and most vegetables. Low temperatures over these regions were in the single digits in the north, low teens across central portions and mid to upper teens in the south. These temperatures were cold enough to wipe out any fruit crops that had reached the blooming stage. At 20 degrees even Peaches at the first pink stage of development will have 50% percent losses while at 15 degrees, as much as 90% losses are likely. Most of the Alabama peach crop was destroyed that year by the freeze. Follow my weather history tweets on Twitter. I am @wxhistorian at Twitter.com.
