Regional Weather: Thursday,
December 19 TX/OK/AR:
Conditions across the region will warm today across the south as severe weather continues to move to the east and
eventually dissipate tomorrow. Clouds with showers will occur to the north in Oklahoma and Arkansas today with clearing
in the afternoon and conditions improving overnight and into tomorrow. In Texas, temperatures will warm, with highs
in the upper 60s today but 5 degrees cooler tomorrow.
A north to northwestern flow across the region will bring moderate winds
to the region along with the cooler air. Tomorrow a west to southwest flow is established as conditions sunny skies and an
overall warming begins. Overnight tonight temperatures will be cool in the 20s and 30s in the west to the low 40s
along the southeastern edge of the Edwards Plateau.
To the north cloudy conditions will prevail this morning with a chance
of scattered showers. Skies
will clear this afternoon and sunny, clear conditions prevail after that. Temperatures will be in the mid 50s today
and tomorrow cooling to near freezing in most localities tonight.
Winds throughout the region will remain moderate from the north to northwest
today switching to westerlies overnight and into tomorrow.
Trajectory weather: The air mass trajectories from the Arbuckle Mountains move towards the southeast on north to northwest winds. The pathways show movement into Louisiana before being turned to the north, or in the case of the upper elevation winds move out over the Gulf of Mexico. The trajectories show characteristics of movement at ground level as the cooler, heavier air moves through the region with little lift therefore any entrained particle should not travel very far. Cloudy skies will prevail this morning but clearing will occur this afternoon and conditions will improve into tomorrow. Temperatures will be in the upper 50s both days with drying conditions and moderate winds.
OUTLOOK: ***Low Threat today***mixed conditions for pollen release today. Conditions
in the
Trajectory Start (s) (shown by black star on map): Sulfur, OK.
