DISCUSSION

KEY MESSAGE 1: Increased fire weather concerns through mid week.

Dry high pressure will continue to settle into the region early this week with RH values in the 20 to 30 percent range each day through Wednesday. On Tuesday night and Wednesday a dry, cold front will move through the Southeast leading to wind gusts of 20 to 30 mph. This combination of dry fuels, a dry air mass, and gusty winds heightens concern for critical fire weather conditions on Wednesday. By Thursday, moisture advection is expected to result in an increase in minimum RH values each day, helping to alleviate most of the fire weather concerns.

Otherwise, no impactful weather expected through the period with rain chances below slight and temperatures within the normal range for the season.

AVIATION /00Z TUESDAY THROUGH SATURDAY/

VFR conditions expected through the forecast period.

High pressure will remain in place across the region through the TAF period with an associated high probability of VFR conditions. A deck of high clouds will persist overnight before shifting offshore by Tuesday afternoon and evening. Winds will pick back up around 14Z as daytime mixing breaks the inversion. Northeast to east-northeast winds are expected to increase to around 10 knots, with gusts up to 20 knots possible through the day on Tuesday.

EXTENDED AVIATION OUTLOOK...The chance of restrictions is low through at least mid-week.
