After a muggy night with lows near 70, tomorrow will be hot & humid with 88-93 & heat indices 96-102. The winds run WSW 5-10 mph turning to the NW at 8-14 mph.
Clouds should bubble up tomorrow, especially ahead of & along the weak surface cold front that will slide through.
Isolated storms are possible, mainly in the afternoon hours (25% coverage).
Some less humid air will move north to south (slowly) tomorrow afternoon-evening behind the front.
Here is the bit less humid air coming in, which will be with us through Wednesday & even into Thursday (through Thursday will turn quite a bit hotter):
Oppressive dew points will overspread area end of the week & through the weekend. Highs will run 91-95 with heat indices as high as 110. It is likely that Heat Advisories & Excessive Heat Warnings will be issued.
Such high dew point will be supported by areas that have had 3X their normal rainfall over the past 30 days. Texas & Louisiana is also getting heavy rainfall, giving an already-healthy start.
Complexes/clusters of storms will feed on the very high dew points near 80. Such high dew points promote torrential, heavy rainfall rates that produce sudden flash flooding. Multiple complexes of storms may pass through the area Saturday night-Monday.
A couple branches of stronger flow aloft still look like to move through the area. This, in combination with the surface cold front & highly unstable environment points to some severe weather risk (wind).
After the intense heat, notice how the reds, purples & pinks are supressed to our south & southwest, not matter how hard they try to move back northward.
This signals that change toward a cooler trend following mid July to early August. 70s & 80s will be common with lows in the 50s & 60s, it appears.
Notice how we go from the intense heat to cooler than normal (overall) mid-July to early August.
After dry weather, a period of wetter weather (tied to the complexes of storms riding through area Sunday-Monday) will occur. However, it looks drier than normal afterward.
