(today and tonight)
An upper level high pressure ridge will begin building across the
Southern Plains today. As a result, expect hot and dry weather
across the area. Also, a heat advisory is in effect this afternoon
and early evening for the western 2/3 of the Big Country and much of
the Concho Valley. Highs will be mainly 100 to 105. Overnight lows
will be in the 70s.
(monday through saturday)
..record high temperatures likely on Monday...
Latest data still indicates that record high temperatures are
likely on Monday afternoon, with the thermal ridge expanding
eastward into the area. Temperatures in the 105-110 are possible
across much of the Big Country and Concho Valley, with a few
locations exceeding 110.
Upper level ridge begins to break down by Tuesday afternoon, with
thickness values decreasing. Highs will be a little cooler,
although well above the 100 degree mark in many locations. A weak
cold front will sag into the Big Country Tuesday night, with
scattered convection developing. Hard to tell how far south any
convection might go, but with northerly and northwesterly flow
aloft, will give it the benefit of the doubt and carry a slight
chance of thunderstorms into the Concho Valley and Heartland.
This northerly flow aloft will continue through the rest of the
week. Mostly dry conditions will prevail until the weekend, with
models suggesting another cold front moving into the area.
Increase in cloud cover and another chance of a few showers and
storms across the area, with highs dropping closer to seasonal
