Area Forecast Discussion|
National Weather Service Houston/Galveston TX
1012pm CST Monday Nov 11 2019
Forecast continues on track. Surface cold front is currently moving across the local waters with the 850 MB front trailing behind it, which will result in a few areas of showers with possible isolated thunderstorms during the next several hours south of I-10. Chance of isolated thunderstorms was added to the Wx grids for the coastal regions as well as the local waters through 6am CST Tuesday. Across the northern half of the CWA, light to moderate rainfall continues with temperatures now in the mid to upper 30s. Thus, the chance of rain with light sleet is expected to prevail across the northern counties through at least 6am CST Tuesday. The model blend has been slightly warmer than observed, thus, another adjustment was made to the temperature forecast for overnight. As of 10pm CST tonight, temperatures over the northernmost counties are nearing freezing...and they are expected to continue to decrease during the next few hours. Will need to continue to closely monitor the temperatures over these regions tonight...a winter weather advisory could be issued for the possibility of freezing rain and sleet. 24
Some interesting temperature data to delve into. The forecast low temperatures for Wednesday morning will be unseasonably cold for this time of year. The forecast lows for Houston, College Station and Galveston are 29, 24 and 38 degrees respectively. Checked the temperatures to see how often the temperature reached these values on or before Nov 13th and the results were startling. For Houston, there has only been one day with a temperature below 29 degrees by the 13th and that was a 28 degree value on November 4 1991. For College Station, there have only been 2 days with a temperature below the forecast value of 24 degrees (20 on Nov 5 1901 and 22 on Nov 4 1901.
Some record low maximum temperatures could be in jeopardy tomorrow as well with high temperatures remaining generally in the 40's. 43
AVIATION... Cold front is off the coast and winds have increased significantly. A mix of IFR/MVFR (Marginal Visual Flight Rules) ceilings will transition to MVFR (Marginal Visual Flight Rules) overnight and to VFR ceilings by mid morning Tuesday. Skies will clear Tuesday afternoon and winds will gradually diminish. As for precipitation tonight, forecast soundings would suggest patchy light rain and drizzle this evening with some potential for some sleet to mix with the rain before the 850 front pushes remaining precipitation toward the coast. 43
