10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

Area Forecast Discussion National Weather Service Houston/Galveston TX 609 AM CST Tue Dec 10 2019
AVIATION. Expecting to see the MVFR ceilings near the coast to spread inland this morning and maybe become IFR, and also expecting to see expanding areas of mainly -SHRA/-RA (some -TSRA cannot be ruled out, but not confident enough to include in area TAFs). N winds behind the early morning cold front will be around 15 to 25 knots inland and 25 to 30 knots near the coast, with higher gusts areawide. Rains will come to an end from west to east late this afternoon through early this evening, but ceilings might take a little longer to lift and clear out with MVFR conditions possibly persisting until late tonight or early tomorrow morning. VFR tomorrow. 42
PREV DISCUSSION. /ISSUED 355 AM CST Tue Dec 10 2019/
DISCUSSION .
A very strong cold front is pushing through Southeast Texas tonight with a broken line of showers. In its wake, look for gusty north winds and temperatures to stay steady or fall through the day today. This means most locations have seen their high temperature for the day already. Additionally, expect widespread, generally light showers to fall across Southeast Texas today, gradually ending from northwest (late this afternoon) to southeast (this evening).
After today, look for generally quiet weather for the next several days with temperatures with cool temperatures slowly rising into early next week, when another cold front will bring our next chance for rain and colder conditions.
SHORT TERM [Through Wednesday] .
The cold front is moving off the coast early this morning. At 3 AM, temperatures have fallen into the lower 50s north and remain in the low to mid 70s at the coast just ahead of the front. These readings will continue to fall as the day progresses and will be accompanied with areas of rain and embedded showers (and maybe an isolated thunderstorm too). Gusty north winds are expected with breezy conditions inland and windy conditions closer to the coast (where wind advisories will be in effect). The rainy conditions will come to an end from west to east beginning later this after- noon or early this evening, and anticipate all activity to be off to our east tonight. Mostly clear skies and much lighter winds will help to set the stage for a cold night tonight with near freezing temperatures possible across parts of our far northern counties. Closer to the coast, low to mid 40s are anticipated. Wednesday will be cool and dry with mostly sunny skies.
LONG TERM [Wednesday Night Through Tuesday] .
By Wednesday evening, the potent upper trough fueling continued showers in the short term will have moved to our east, with northwest flow aloft and northeast winds at low levels providing us with something close to a Wednesday repeat on Thursday. Under a clear sky, expect overnight lows to remain cold into the morning, but should allow for slightly warmer highs.
Very weak reinforcing fronts look to slide into the area both on Thursday night and on Saturday as high pressure tries to build over the region. They should largely be ineffective, but could allow for some showers over the Gulf and possibly the immediate coastal areas Thursday night. Despite these fronts, look for the sustained warming trend to continue through the weekend with offshore or variable winds.
Early next week, another upper trough will move in from the west, and look for a line of showers and some thunderstorms to drive down from North Texas on Monday. Keep an eye on temperatures behind this front, as there's generally good guidance in an arctic airmass advecting in. For now, there's also good consensus for the coldest air to slide east of us before making it to our latitude, so the temperatures in the forecast are cold, but not very abnormally so. But, should that coldest air take a slightly different trajectory, we may have to dial those temps down.
MARINE .
Cold front is moving across Matagorda Bay at 3 AM and will continue to work its way off the coast and through the coastal waters this morning. Areas of rain with embedded heavier showers can be expected for much of the day today. North winds will significantly strengthen and become gusty behind the front. Advisory flags for the Bays and Gale Warnings for the coastal waters will be in effect today and on into this evening, and they might need to be extended into the late night through early morning hours tomorrow. As the day progresses tomorrow, the north to northeast winds and the rough seas will begin to come down, and this trend will continue on into Thursday. A more southwest to south to southeast wind direction can be expected at the end of the week and on into the weekend. Look for another cold front to move off the coast and through the waters next Monday.
CLIMATE .
Several warm records were set yesterday as heat spiked ahead of this strong cold front. Here is a summary of the records reached:
High Temperature: City of Houston (IAH) - 84 degrees (82, 2007) Hobby Airport - 84 degrees (82, 2007) City of Galveston (GLS) - 78 degrees (tied, 2007)
High Minimum Temperature: City of Galveston (GLS) - 69 degrees (68, 2007)
Additionally, the 84 degree temperature came one degree short of the monthly high temperature record for both the City of Houston and Hobby Airport. The record at both remains remains 85 degrees, which was set on December 3, 1995 at IAH and December 3, 1933 at Hobby Airport.
