.KEY MESSAGES...
- Cool and comfortable mornings Tuesday and Wednesday.
- Mostly dry and seasonable forecast through the weekend.
&&
.SHORT TERM (THROUGH WEDNESDAY)... Cool crisp mornings and warm afternoons are expected both today and Wednesday. Light north to northeasterly flow through the column has allowed drier air to work into the region, resulting in a couple cooler mornings today and tomorrow. Temperatures will dip as low as the lower 60s over the Hill Country with mid to upper 60s elsewhere. Highs will remain warm, in the upper 80s to middle 90s Tuesday and Wednesday. Weak ridging approaches on Wednesday, resulting in increased high temperatures.
&&
.LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)... Mid-level ridging will take hold over western and central Texas Wednesday through late week. This will result in mainly dry days outside of some seabreeze showers or storms over the Coastal Plains. Beyond any seabreeze activity, it will be a mainly dry and warm week with highs in the mid to upper 90s and mornings in the upper 60s to lower 70s.
&&
.AVIATION (12Z TUESDAY THROUGH WEDNESDAY)... VFR flying conditions prevail today through Wednesday morning. Moisture profiles indicate thin MVFR/IFR clouds overnight into Wednesday morning.
