Area Forecast Discussion National Weather Service Houston/Galveston TX 400 PM CST Sat Dec 7 2019

Short Term (Through Tomorrow). The short term will be relatively quiet with light winds, near normal temperatures, and no chance of precipitation. The flow does become more easterly then southeasterly through the evening and over night. This will bring in some increased low level moisture developing into some patchy fog during the overnight hours. Guidance is currently picking up on the patchy fog developing mainly south of Houston shortly after midnight, then up in Polk and San Jacinto counties by sunrise. Any fog that does form should dissipate shortly after sunrise. The southerly wind on Sunday will result in high temperatures becoming a few degrees warmer than today, but the skies will be more partly cloudy. Fowler

Long Term (Tomorrow night through Saturday). This period beginning the new work week will provide change in the weather. The next impetus to early work week precipitation will be the emergence and development/evolution of a positively-tilted Central U.S. upper trough out of the Rockies into the Plains states early Monday. The trough axis is forecast to deepen through the day Monday as it progressively digs southeast across the Lone Star. At the surface, the low (pressure) reflection will begin to get its act together over the Panhandle/western Texas counties Monday afternoon and travel along the lower level cold front moving across the escarpment around sunset. This front is timed to reach our northern counties late Monday night and be off the coastline by sunrise Tuesday. A shallow cool air mass sliding in under a warmer mid-layer southwesterly flow will create enough isentropic lift to produce just periods of light rain (drizzle) or rain showers through the day Tuesday. Decent upper level support coupled with robust frontogenesis suggest that inland storms could get rooted aloft with more surface-based storms occurring far offshore Tuesday afternoon into evening. As of now, the warm nose looks to be too stout to mention any surface-based storm activity. Showery weather will produce low QPF; average areawide quarter to a half of an inch.

Pleasant post-frontal mid to late week weather as the upper air pattern becomes more zonal. Light north winds on Wednesday will become northeast Thursday before a reinforcing cool front (mainly dry inland with slight offshore -shra chances) keeps winds north Friday going into the weekend. A pristine start to next weekend under clearing skies under variable winds . morning 40s warm up into the very comfortable 60s with afternoon humidities falling to under 50%. 31

MARINE. Light onshore flow begins this evening and continue through Sunday, then strengthening on Monday ahead of an approaching cold front. This front should pass through the region Tuesday morning bringing increased rain chances as it passes through. The frontal passage will usher in moderate to strong offshore flow Tuesday night through Wednesday approaching advisory criteria with 5 to 7 foot seas. Fowler

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
