..SYNOPSIS
MID-LEVEL RIDGING OVER THE WESTERN US IS FORECAST TO MOVE EASTWARD
AS THE OVERALL UPPER-AIR PATTERN BECOMES MORE AMPLIFIED. HIGH
PRESSURE OVER THE GREAT BASIN WILL MOVE INTO THE ROCKIES AS A COLD
FRONT MOVES SOUTH OVER THE CENTRAL US. ASIDE FROM SOME RESIDUAL
OFFSHORE FLOW OVER PARTS OF SOUTHERN CA, WIDESPREAD FIRE-WEATHER
CONCERNS ARE NOT EXPECTED.
..SOUTHERN CA
OFFSHORE PRESSURE GRADIENTS AND THE RESULTING SURFACE WINDS ARE
EXPECTED TO GRADUALLY WEAKEN EARLY THIS MORNING AS HIGH PRESSURE
SHIFTS EASTWARD OVER THE ROCKIES AND GREAT BASIN. WHILE WINDS SHOULD
GENERALLY WEAKEN, SOME LINGERING, LOCALLY ELEVATED FIRE-WEATHER
CONDITIONS MAY CONTINUE IN THE FOOTHILLS OF LOS ANGELES AND VENTURA
COUNTIES THROUGH THE FIRST HALF OF THE AFTERNOON. LIMITED IN SPATIAL
COVERAGE AND DURATION, FIRE-WEATHER CONCERNS ARE NOT EXPECTED TO BE
WIDESPREAD. FIRE-WEATHER CONCERNS WILL END AS ONSHORE FLOW RETURNS
THIS EVENING.
..CENTRAL PLAINS
A MODERATELY STRONG DOWNSLOPE WIND EVENT BEHIND THE DEEPENING
SHORTWAVE TROUGH WILL ALLOW FOR STRONG GUSTS OF 30-40 MPH ACROSS
PARTS OF EASTERN CO AND WESTERN NE/KS THIS AFTERNOON. HOWEVER, THESE
WINDS ARE ONLY EXPECTED TO OVERLAP WITH COOLER SURFACE TEMPERATURES
AND MODERATELY LOW RH FOR A FEW HOURS. WHILE SOME LOCALLY ELEVATED
FIRE-WEATHER CONDITIONS ARE POSSIBLE, THE LACK OF DRIER FUELS AND
THE LIMITED OVERLAP OF DRY/WINDY CONDITIONS SHOULD NEGATE MORE
WIDESPREAD FIRE-WEATHER POTENTIAL.
