Updated national weather service austin san antonio tx 533 pm cst Sun feb 17 2019 Update Please see the 00z aviation forecast discussion below. Aviation Vfr conditions are in store at area TAF sites through the current forecast period. Only high clouds are expected through tomorrow as winds along the i-35 corridor remain from the northeast. Similar conditions out west at drt with winds transitioning to a more southeasterly direction by mid-morning Monday. Prev discussion issued 251 pm cst Sun feb 17 2019 short term (tonight through Monday night)... the current upper air pattern is characterized by broad troughing across the western CONUS and ridging across the eastern CONUS with southwesterly flow aloft across south central texas. Drier air has filtered in behind the cold frontal passage this morning. Low rh values and some gusty winds have yielded some slightly elevated fire weather conditions this afternoon. The rest of today should be quite pleasant with temperatures tonight dropping into the upper 30s to low 40s across the majority of the region. Unfortunately, the brief period of mostly clear skies will be squelched with the arrival of more cloud cover as we progress through Monday afternoon due to the approach of another upper level trough from the northwest. High temperatures tomorrow will be below seasonal normals, ranging from the mid 50s to low 60s. Weak isentropic ascent will lead to slight chances for showers and drizzle overnight Monday into Tuesday morning. Long term (Tuesday through Saturday)... rain chances will increase throughout the day on Tuesday as the |
trough axis approaches, with the williamson and lee county areas being most favored for shower activity. Accumulated rainfall should remain below a quarter of an inch. Temperatures on Tuesday will be much cooler than seasonal normals. Wednesday should generally remain dry as the upper level trough lifts to the northeast, with only 20% pops across the coastal plains. There should be some breaks in the clouds, allowing for partly sunny conditions. Highs will be in the low to mid 60s. Generally unsettled weather returns for Thursday through Saturday due to the approach of another upper level trough from the northwest, bringing mostly cloudy skies and chances for rain. The GFS is more bullish in terms of rain coverage and accumulated rainfall than the ecmwf. For now, have mostly used a model blend for pops and qpf. Even the more bullish GFS yields less than an inch of total accumulated rainfall for all areas except for the northeastern counties of the cwa. High temperatures during this time period will gradually warm, with highs around 60 for Thursday and warming up to the upper 60s to lower 70s by Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
