..SYNOPSIS
A LOW-LATITUDE MIDLEVEL TROUGH WILL CROSS THE SOUTHERN ROCKIES AND
ADJACENT HIGH PLAINS DURING THE DAY. WITHIN THE BASE OF THE TROUGH,
MODERATE-STRONG DEEP-LAYER WESTERLY FLOW WILL OVERSPREAD A DEEPLY
MIXED POST-DRYLINE AIR MASS ACROSS SOUTHEAST NM INTO THE
TRANS-PECOS. SUSTAINED WESTERLY SURFACE WINDS AROUND 20 MPH COUPLED
WITH 10 PERCENT RH WILL FAVOR ELEVATED TO LOCALLY CRITICAL
FIRE-WEATHER CONDITIONS.
FARTHER EAST, BREEZY EASTERLY SURFACE WINDS (AROUND 10-15 MPH) WILL
DEVELOP AMID 30 PERCENT RH ACROSS PARTS OF SOUTHERN AND CENTRAL FL
DURING THE AFTERNOON -- ALONG THE SOUTHWESTERN PERIPHERY OF THE
BERMUDA HIGH. GIVEN DRY/RECEPTIVE FUELS, ELEVATED FIRE-WEATHER
CONDITIONS ARE EXPECTED.
DRY/OFFSHORE FLOW IS EXPECTED ACROSS PARTS OF THE NORTHEAST AND
MID-ATLANTIC STATES TODAY, WHICH MAY PROMOTE LOCALLY ELEVATED
FIRE-WEATHER CONDITIONS. HOWEVER, A MODEST PRESSURE GRADIENT AND
MARGINAL SURFACE WINDS (AROUND 10-15 MPH) SHOULD GENERALLY LIMIT THE
FIRE-WEATHER RISK.
