Friday, December 14
The High Pressure Ridge (HPR) over the Eastern half of the nation continues to slide east, this morning. SW Flow is developing in advance of a trough that is moving toward the SE U.S. This front is associated with a Low Pressure System that is continuing to move through the CPlains and into the Midwest. A spin-off low will be developing over the ArkLaTex area during the next day or so.
With SE winds continuing to gradually increase over the coastal waters and into SE TX/SE LA, more moisture and humidity will be pumped into the area (ahead of an approaching cold front and in lieu of a HPR that is departing to the East). High and mid level clouds are already invading the region from the west and models are not agreeing at all with the timing of this system (in Louisiana).
Warmer and more humid conditions return into the forecast today, along with increasing clouds throughout the day. Surface wind speeds will develop and swing around to the SE, as well.
For the rest of the day and this weekend,
Highs are expected to reach the mid 60-s with mostly cloudy skies overnight. There will be little change in temps overnight as the clouds will act like a blanket and limit the heat content lost throughout the overnight hours. Some locations will see a temperature difference of as little as 10 degrees.
Today we will see increasing clouds an overnight (will bring with it) rising rain chances as a cold front slowly approaches the area. This front will stall out over Central Louisiana and allow for a god chance for rain, tonight and tomorrow morning. A secondary system and separate cold front will move through the area and help kick the stalled front through the area Sunday and Sunday night.
For the rest of the 7day planner
Rain chances will end by early Monday, with slightly cooler and drier weather returning for Monday afternoon and Tuesday. Morning lows will be normal Tuesday morning with slightly above average highs Monday and Tuesday. Nevertheless, expect Plenty of sunshine and a gradual warming trend through mid week with a secondary round for rain Next Thursday.
This system will NOT drop temperatures very much and the beginning of the work week will bring with it, chilly morning lows in the 40's.
TODAY...Increasing clouds with seasonably warm temps. Highs in the 60s. S/SE wind 2-12 mph. There will be a chance (30%) for light rain beginning in the evening.
FRIDAY NIGHT...Mostly cloudy and much warmer with off/on
sprinkles, becoming scattered (30%) rain. Lows in the 50s. S/SE wind 4-10 mph.
