AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
3 PM CDT TUE APR 10 2001

SEVERE THUNDERSTORM POTENTIAL TONIGHT AND EARLY WEDNESDAY...THEN
TEMPERATURES AND WIND ARE MAIN FORECAST CONCERNS.

SFC ANALYSIS SHOWING LOW OVER WESTCENTRAL KANSAS WITH WARM FRONT
EAST FROM THE LOW NOW LIFTING NORTHEAST ACROSS NORTHEAST KANSAS.
SHORTWAVE OVER NORTHERN OK LIFTING NORTHEAST IS HELPING COMPLEX OF
THUNDERSTORMS OVER THE AREA. WOULD EXPECT THUNDERSTORMS NOW OVER THE
AREA TO LIFT OFF TO THE NORTHEAST WITH A BREAK IN THE THUNDERSTORMS
EXPECTED BEFORE MORE THUNDERSTORMS DEVELOP OFF TO THE WEST ALONG
DRYLINE THEN SWING RAPIDLY NORTHEAST ACROSS THE CWA THROUGH THE
NIGHT.

INCREASING LOW LEVEL JET AND SHEAR WITH DYNAMIC FORCING AHEAD OF THE
UPPER SYSTEM STILL SUPPORTS MORE SEVERE WEATHER POSSIBLE
TONIGHT...SO WILL CONTINUE TO MENTION POSSIBLE SEVERE IN THE ZONES
TONIGHT. ALTHOUGH THUNDERSTORMS MOVING INTO THE AREA OVERNIGHT MAY
STILL PRODUCE MORE HEAVY RAINFALL...EXPECT IT TO BE BRIEF AND FAST
MOVING. MODELS ALSO INDICATING THE HEAVIER RAINFALL TONIGHT TO THE
BE SOUTH AND EAST OF THE CWA. THEREFORE, WILL NOT GO WITH FLASH
FLOOD WATCH AT THIS TIME...BUT STILL MENTION HEAVY RAINFALL IN THE
ZONES.

DRY SLOT COMES INTO THE WESTERN PORTIONS OF THE CWA IN THE MORNING
AND PROGRESSES EASTWARD ACROSS THE CWA THROUGH MIDDAY. ALTHOUGH SOME
WRAPAROUND STILL POSSIBLE IN THE NORTHCENTRAL...EXPECT MOST PRECIP
TO OCCUR PRIOR TO THE SLOT SLOT IN THE MORNING HOURS WITH MOST OF
THE AFTERNOON CONVECTION EXPECTED TO THE EAST OF THE CWA. WILL
CONTINUE WITH POPS FOR TUESDAY WORDED AS MAINLY IN THE MORNING. WILL
GO WELL ABOVE MOS GUIDANCE AND EVEN FAN WITH HIGHS GENERALLY 70 TO
75. WILL GO WITH WINDS BECOMING SOUTHWEST 20 TO 30 WITH HIGHER
GUSTS...ALTHOUGH MID SHIFT WILL HAVE TO CONSIDER POSSIBLE WIND
ADVISORIES WED INTO WED NIGHT. WILL CONTINUE TREND OF HIGHS COOLING
INTO THE 60S THURSDAY WITH LOWS IN THE LOWER TO MIDDLE 40S.
