12Z Taf issuance.
Cold front approaching Acadiana early this morning and can be seen by a few very light returns on local radar. Satellite imagery depicting widespread post-frontal stratus over the remainder of the area with moisture locked in at 850 hPa and below. Moisture and resultant cloud will remain in place and simply phase into our next system arriving later Thursday. Weak Cold Air Advection and cloud cover will limit any significant warmup through the day, but still expected to top out near 60 area-wide from early morning lows near 50. Lows in the mid 40s on tap for tonight and highs reach the upper 50s to 60 for Thursday. Rain chances return Thursday night.
Southern stream shortwave approaches the area Thursday night into Friday bringing another shot of moisture and showers to the area. Feature then advances east of the area with a dry westerly flow aloft initially following, becoming north as a second shortwave drops southeast through the lower and mid Mississippi valleys. Column will be dry through the weekend with PWATs (Precipitable Waters) dropping to 0.25 inches or below. Expecting clear and cool nights, sunny and mild days. Pattern will remain progressive with the next system arriving Monday into early Tuesday. Feature showing some good kinematics and sufficient thermodynamics at this time to at least suggest a potential severe weather threat. System will watched closely over the coming days.
A brief period of moderate to strong northerlies can be expected today in the wake of another frontal passage. An extended period of offshore flow will continue through the remainder of the week. Rain chances will return Thursday afternoon and continue through Friday as another disturbance aloft approaches the area.
