..SYNOPSIS
AS AN UPPER LOW SLOWLY MEANDERS INTO THE NORTHERN ROCKIES ON DAY
2/FRIDAY, HIGH PRESSURE IN THE SOUTHEAST WILL RETROGRADE WESTWARD
AND CENTER OVER THE ARKLATEX REGION. AS A RESULT, ABOVE NORMAL
TEMPERATURES WILL CONTINUE FOR MUCH OF THE SOUTHERN PLAINS AND DEEP
SOUTH WHERE RAINFALL NEGLECTED FUELS HAVE BECOME INCREASINGLY
RECEPTIVE.
..SOUTHERN PLAINS
A SURFACE TROUGH AHEAD OF AN ADVANCING COLD FRONT ACROSS THE CENTRAL
PLAINS WILL PROMOTE SLIGHTLY HIGHER SOUTH-SOUTHWEST WINDS TO
PORTIONS OF THE SOUTHERN PLAINS ON DAY 2/FRIDAY. WHILE GUIDANCE
DEPICTS RH VALUES TO BE AT OR ABOVE 25-30%, OBSERVED VALUES WILL
LIKELY BE MUCH LOWER AS A RESULT OF AN INCREASING VAPOR PRESSURE
DEFICIT (90TH PERCENTILE OR GREATER FOR THE LAST 15-30 DAYS) AMID AN
EXHIBITED DECREASE IN EVAPOTRANSPIRATION DUE TO LONG TERM DROUGHT
AND STRESSED FUELS. SUSTAINED WIND SPEEDS OF 10-15 MPH ARE EXPECTED
ATOP VERY DRY AND RECENTLY RECEPTIVE FUELS, NECESSITATING AN
INTRODUCTION OF ELEVATED HIGHLIGHTS ACROSS SOUTHWESTERN OKLAHOMA AND
NORTHERN TEXAS.
