DISCUSSION

KEY MESSAGE 1...The heat and humidity continues for the next several days.

KEY MESSAGE 1 DESCRIPTION...Though slightly flattening in amplitude mid level ridging will be in place across the Gulf States though Monday with some slight amplification and retrogression thereafter. A healthy piedmont trough develops Monday and Tuesday bolstering the warmth. Depending on phasing of dewpoints and temperatures Monday, apparent temperatures in excess of 105 degrees and perhaps 110 degrees look possible. A potential fly in the ointment is the mixing down of lower dewpoints with heating as mixing depths look fairly deep. For now, have held off on an advisory to give later shifts time to get better clarity on this. Either way, Monday will be hot. This uncertainty will repeat itself on Tuesday.

AVIATION /18Z SUNDAY THROUGH FRIDAY/

Mainly VFR conditions expected though there is potential for restrictions in isolated to scattered showers and storms. Maintained PROB30 groups for showers/storms roughly 18Z-24Z , as a lingering front and sea breeze spark convection. Cig/vsby restrictions will be possible again tonight but potential at individual sites too low for inclusion in the forecast attm.

Extended Forecast...VFR conditions are expected much of the week outside of any convection. Afternoon to early evening storms could result in brief restrictions at times.

MARINE

Tonight through Thursday... Overall expect light winds through the period, though there could be some enhancement in the afternoon in sea breeze areas in south to southwest flow Monday afternoon. Overall, winds and seas should be relatively benign outside convection through Thursday.
