Area Forecast Discussion National Weather Service Houston/Galveston TX 1037 PM CST Fri Mar 5 2021

SHORT TERM. Cold front pushing off the coast near Matagorda and near Freeport and Pearland. Some low clouds/fog right ahead of the front. Drier air pushes through shortly and will end the fog threat but cloudy skies will remain overnight. Spotty showers near the low in the vicinity of Houston/Galveston/Sugarland area for a few more hours.

AVIATION [06Z TAF Issuance]. VLIFR/LIFR in the vicinity of HOU/SGR/LBX/GLS ahead of the frontal boundary but as the front pushes through will see winds increase out of the NNW or N and may get gusty in the 12-19kt range for a few hours in the wake of it. MVFR decks should prevail through mid early morning then VFR clearING from the northeast throughout the late morning/early afternoon.

PREV DISCUSSION /Issued 321 PM CST Fri Mar 5 2021/.

LONG TERM [Sunday through Saturday].

A broad ridge aloft over the western CONUS begins to migrate eastward into the Plains Saturday. This pattern will bring a prolonged stretch of mostly dry, warm and humid weather. Saturday and Sunday look pleasant with northwest winds, mostly sunny skies and highs reaching the mid to upper 60s.

An upper-level shortwave will track through southeast TX Sunday into Monday, but little, if any impact is expected due to strong subsidence and dry-air aloft.

Pattern at the surface will be dominated by persistent southerly winds and ridge aloft. This will result in mostly cloudy skies and warm and humid conditions. Isolated/spotty showers cannot be rule out throughout the week, given moisture advection and some weak mid- upper level disturbances.

The main weather concern will be temperatures, mainly after Tuesday where 850 hPa temperatures begin to increase into the 10-16C range. Latest NBM guidance continues to struggle with temperatures, suggesting a cold bias. In collaboration with surrounding offices, have increased temperatures a few degrees to produce highs in the upper 70s to low/mid 80s. Breezy south winds will also be ushering a moist Gulf airmass, leading to an increase in dewpoints after Wednesday.

As the ridge weakens towards the end of the week, an upper-level trough over the Pacific northwest will begin to track eastward into the Rockies, dragging a cold front over central/eastern TX by Thu- Fri timeframe. Have included rain chances through this period. 05

MARINE.

Isolated to scattered showers are expected this afternoon and evening as a cold front moves through. Although conditions look marginal, a few thunderstorms may develop this evening. Behind the front, gusty north winds are expected along with elevated seas up to 7 ft. Have issued a Small Craft Advisory for all Gulf waters from midnight Saturday through Saturday afternoon. Moderate onshore flow quickly develops by Sunday as the surface high moves eastward. This pattern will prevail through much of the week. Given persistent east to southeast flow, seas will range in the 4 to 6 ft at times. Caution flags and/or advisories will be possible at times. 05
