...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
THE CENTRAL PLAINS AND SOUTHEAST FLORIDA...
..SUMMARY
A FEW STRONG TO SEVERE STORMS ARE POSSIBLE ACROSS PORTIONS OF THE
CENTRAL PLAINS AND ACROSS SOUTHEAST FLORIDA.
..SYNOPSIS
MID-LEVEL RIDGING WILL SHIFT EAST FROM THE ROCKIES TO THE CENTRAL
PLAINS ON FRIDAY. AT THE SURFACE, A LEE CYCLONE WILL DEVELOP IN THE
SOUTHEAST COLORADO VICINITY. A WARM FRONT WILL EXPAND EAST FROM THIS
SURFACE LOW WITH A DRYLINE SOUTH ACROSS THE HIGH PLAINS.
..CENTRAL PLAINS
MID TO UPPER 60S DEWPOINTS ARE FORECAST EAST OF THE DRYLINE ON
FRIDAY AFTERNOON. AS TEMPERATURES WARM, MODERATE INSTABILITY WILL
DEVELOP ACROSS OKLAHOMA AND NORTH TEXAS. DIURNAL CONVECTION ALONG
THE DRYLINE REMAINS QUESTIONABLE DUE TO RISING HEIGHTS ALOFT AND
SIGNIFICANT INHIBITION. HOWEVER, ONCE THE NOCTURNAL LOW-LEVEL JET
STRENGTHENS, SCATTERED CONVECTION IS LIKELY NORTH OF THE WARM FRONT
ACROSS THE CENTRAL PLAINS. MODERATE ELEVATED INSTABILITY AND
MODERATE TO STRONG EFFECTIVE SHEAR WILL SUPPORT SOME POTENTIAL FOR
LARGE HAIL FROM THIS ACTIVITY.
..SOUTHEAST FLORIDA
COOL TEMPERATURES ALOFT (-10C AT 500MB) AND MODERATE INSTABILITY ARE
FORECAST ACROSS THE FLORIDA PENINSULA ON FRIDAY. THUNDERSTORMS ARE
LIKELY ALONG THE SEA BREEZE BY EARLY AFTERNOON. MODERATE DEEP-LAYER
SHEAR WILL SUPPORT THE POTENTIAL FOR SOME STORM ORGANIZATION,
INCLUDING SOME ROTATING UPDRAFTS. LARGE HAIL AND DAMAGING WIND GUSTS
WILL BE POSSIBLE FRIDAY AFTERNOON ACROSS SOUTHEAST FLORIDA.
