Big changes in temperatures and humidity on the way.

Forecast Synopsis KAVU 11-05-22

 

Tonight: Clear to partly cloudy. Low: 57

Winds: Light and variable.

Sunday: AM-Clouds, PM-Sun, 20% chance of rain. High: 84 Low: 71

Winds:  SE 10 mph.

Extended forecast: Monday through Saturday: Onshore flow will quickly return to the Crossroads increasing temperatures and humidity Sunday afternoon.  A warm front will bring a slight chance of rain and isolated thunderstorms beginning Sunday evening through early Monday morning.  Winds will shift from north/northeast to southeast primarily, at 10-15 mph for most of the week.  Mid-level high pressure builds in midweek giving us rain-free, warm and muggy conditions through Friday.  The next front could arrive Friday, however model guidance is presently not in agreement as to the timing or intensity.  High temperatures will be in the mid to upper 80s through Thursday.  Lows will be in the mid to upper 60s with possibly lower temperatures by Friday depending on the timing of the next cold front.

Synopsis: Isolated showers and thunderstorms will be possible Sunday night into Monday morning courtesy of a weak boundary moves onshore and increasing moisture. While a mid-level high will build into the area and the associated subsidence will limit precipitation chances for most locations, isolated showers and storms will also be possible Tuesday afternoon for the Gulf waters and portions of the Coastal Bend moisture values remain relatively high.

Onshore flow will continue to filter in warm moist air, leading to muggy and generally rain free conditions Wednesday and Thursday.  Highs will generally be in the mid to upper 80s through Thursday, with nighttime lows in the 60s to 70s.

Cooler temperatures are forecast to return Friday as another cold front pushes through South Texas. Given that it is later in the forecast period, have kept with slight rain chances. Current model guidance differs on the timing and intensity of the front.
