Mild & Sunny – More Wet Weather

Posted on: 9:02 am, February 24, 2013, by

High pressure moved into the Tennessee Valley overnight and is centered over the Ohio River Valley this morning.  Cooler and drier air filtered in overnight as well, allowing for a mainly clear sky, with temperatures cooling low to mid 30s.  There were some patches of dense fog that developed in Northeast Alabama and south towards Birmingham earlier this morning, with freezing fog reported in Scottsboro.  Thankfully most of the fog has lifted and any lingering fog will clear within the hour. There was also some frost on rooftops, grass and cars this morning as well.

A mostly sunny sky will prevail all day and will aid in warming temperatures into the upper 50s, with a few locations possible reaching into the low 60s this afternoon.  Despite the nice warm up, a northerly breeze will make it feel like it’s in the the low to mid 50s for the majority of the day. Tonight will not be as cold as this morning, with the wind picking up overnight and becoming easterly, along with increasing clouds ahead of an approaching storm system to our west. Overnight temperatures will cool into the upper 30s and low 40s.

Monday/Tuesday:.
Showers may move into North Alabama as early as Monday morning, spreading from south to north throughout the day as a warm front lifts north of the area.  It will be breezy on Monday with a sustained wind out of the east-southeast between 10-20 mph, with higher gusts possible. Rain chances will remain in the forecast throughout the day Monday, before a cold front moves through Monday night, with heavier showers and storms possible. A narrow tongue of moisture will try to make its way into northwest Alabama ahead of the cold front, which could enhance the threat for a stronger storm, but the best moisture will stay south of the Tennessee Valley and that is where the strongest storms will stay (mainly along the Gulf Coast). Can’t rule out an isolated strong wind gust, but the threat for severe weather will be across south Alabama.

As rain departs and colder air moves in, as an upper level low pressure system tracks northeast from Tennessee into Kentucky and the Ohio River Valley, it could produce a few snow flurries or sleet, especially in southern middle Tennessee.  Little to no accumulation is expected at this time.  Farther north, around and north of Nashville, will have the greatest chance for light accumulation and possible travel impacts.  Precipitation totals through Tuesday morning will range between 0.5-1.0″, with isolated higher amounts possible.  The highest totals will remain to the south of the Tennessee Valley, closer to the moisture source of the Gulf of Mexico. Below is the Hydrometeorological Prediction Center’s Day 1-2 Quantitative Precipitation Forecast.

Wednesday – Saturday:
The disturbed/active weather pattern will stick around for the entire week, with waves of energy keeping precipitation chances in the forecast along with temperatures below average for late February, early March.  Rain will be the likely type of precipitation, but some light wintry precipitation may also mix in, though no major winter storms are in the forecast. Timing remains unclear at this time and no major issues are expected, though this is something we will continue to monitor over the coming days.

Enjoy the beautiful day today as the unsettled weather pattern continues through the work week!
