Area forecast discussion, Oct 17, 2:50 AM CDT, 2 hours 20 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 250 AM CDT SAT OCT 17 1998 TEMPERATURES WILL BE THE MAIN CONCERN WITH THIS PACKAGE. THE NGM AND ETA WERE ONCE AGAIN SIMILAR...SO I WILL CONTINUE TO FOLLOW THE NGM SOLUTION PER PREVIOUS FORECASTS. LOW PRESSURE IN SW NEBRASKA WILL RAPIDLY MOVE NORTHEAST INTO THE GREAT LAKES REGION TODAY DRAGGING A COLD FRONT ACROSS THE CWA. ESTIMATED TIME OF PASSAGE WILL BE AROUND NOON AT RSL...20Z AT SLN... 23Z AT ICT AND 04Z AT CNU. COPIUS AMOUNTS OF MOISTURE AND SOME WEAK ISENTROPIC LIFT WILL COMBINE WITH THE DYNAMICAL FORCING OF THE FRONT TO PRODUCE RW/TRW AGAIN ACROSS THE CWA. THE BETTER CHANCES WILL LIE TO THE EAST OF I-135 IN THE DEEPER MOISTURE. THEREFORE...THE POP CHANCES WILL BE GRADUATED AS SUCH. HIGH TEMPERATURES WILL BE DIFFICULT SINCE THE NGM IS GIVING ME PROJECTED HIGHS LOWER THAN THE CURRENT DEWPOINTS AT RSL AND SLN. SO...I WILL TEND TO GO SLIGHTLY HIGHER IN THOSE LOCATIONS...HOWEVER...STEADY READINGS MAY BE THE CALL WITH FALLING TEMPS IN THE AFTERNOON WITH FRONTAL PASSAGE. FURTHER EAST AND SOUTH OF THE FRONT...THE TEMPS SHOULD REBOUND A BIT TODAY...MORESO IN THE SE SECTIONS THOUGH. THE PRECIPITATION WILL CONTINUE AHEAD OF THE FRONT TONIGHT IN THE SE SECTIONS...ALL OTHER SECTIONS SHOULD START TO SEE SOME DRIER AIR FILTERING INTO THE CWA WITH SUBSIDENCE AND DOWNGLIDE ON A 300K SURFACE. BEHIND THE FRONT...THE NGM SEEMS A BIT TOO MOIST SO I AM GOING TO BE A BIT LOWER ON THE OVERNIGHT LOWS...ESPECIALLY IN THE CENTRAL SECTIONS. HIGH PRESSURE WILL DOMINTE SUNDAY...SO MOSTLY CLEAR SKIES WILL BE THE RULE. THE FWC NUMBERS LOOK REASONABLE AS THE H8 TEMPS WILL BE AROUND 8C. EXTENDED... WILL LEAVE THE EXTENDED ALONE EVEN THOUGH THE MRF CONTINUES TO HINT AT SOME FORM OF PRECIPITATION ON TUESDAY. THE DAY SHIFT MAY HAVE TO LOOK INTO THIS SCENARIO A BIT MORE.
