AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 1020 PM CDT SUN APR 15 2007 .UPDATED AVIATION DISCUSSION... .DISCUSSION... SHORT TERM (TONIGHT-TUESDAY)... UPPER RIDGING HAS AMPLIFIED IN THE WAKE OF A POWERFUL EAST COAST STORM TODAY...AND WILL KEEP THINGS QUIET AND NOTICEABLY WARMER THROUGH THE NEXT 36 HOURS. SURFACE HIGH PRESSURE WILL MIGRATE EAST THE REGION TOMORROW...ALLOWING FOR ABUNDANT SUNSHINE AND MILD 70 DEGREE PLUS WEATHER AS SOUTHERLY RETURN FLOW INCREASES. MEANWHILE...A MOISTURE-STARVED STORM SYSTEM OVER THE SOUTHWEST WILL BEGIN TO MOVE EASTWARD DURING THE PERIOD AS A STRONGER WAVE CRASHES INTO THE NORTHERN PACIFIC COAST MONDAY NIGHT. THE LEAD SYSTEM IS EXPECTED TO CONTINUE AN EASTWARD TRACK OVER THE SOUTHERN PLAINS...PROVIDING LITTLE IN THE WAY OF DIRECT IMPACT. HOWEVER...A WEAKNESS BETWEEN THIS SYSTEM...AND THE RE-ENERGIZED CUT-OFF OVER THE GREAT LAKES WILL PROMOTE HEIGHT FALLS AND WEAK SURFACE FRONTOGENESIS OVER THE AREA TUESDAY AFTERNOON. FORECAST SOUNDINGS DO SHOW SUFFICIENT (500 J/KG) LOW LEVEL CAPE ACROSS NORTHERN MISSOURI DURING THE LATE AFTERNOON AND EARLY EVENING HOURS...ALTHOUGH THIS WILL BE SOMEWHAT DEPENDENT ON THE AMOUNT OF MOISTURE RETURN...LOW LEVEL CONVERGENCE AND ANTECEDENT CLOUD COVER DURING THE DAY. NAM SOLUTION IS NOT UNREASONABLY IN DEPICTING A BAND OF SCATTERED FRONTAL CONVECTION DEVELOPING ACROSS NRN MO TUESDAY AFTERNOON AND MOVING SLOWLY SOUTHWARD DURING THE EVENING HOURS. WILL KEEP POPS IN THE 25-30 PERCENT RANGE FOR NOW GIVEN THE CONDITIONAL FACTORS...BUT A STRONGER LOW LEVEL JET TOMORROW NIGHT AND GREATER SURFACE HEATING BETWEEN THE TWO TROUGHS ON TUESDAY COULD PROVIDE THE NECESSARY INGREDIENTS FOR SHOWERS AND A FEW STORMS. BOOKBINDER LONG TERM (WEDNESDAY-SUNDAY)... THE EXTENDED PERIOD WILL START OUT WITH NEAR NORMAL TEMPERATURES WEDNESDAY AS UPPER RIDGING BUILDS BACK INTO THE AREA BEHIND THE DEPARTING UPPER LEVEL SYSTEM ACROSS THE LOWER MISSISSIPPI VALLEY. SEVERAL DAYS OF SOUTHERLY SURFACE WINDS WILL ALLOW FOR A SIGNIFICANT WARMING TREND WITH INCREASING MOISTURE BY LATE IN THE WEEK. IN GENERAL...FOLLOWED THE WARMER ECMWF SOLUTION AND HEDGED TEMPERATURES ABOVE MEX GUIDANCE. BY FRIDAY...HIGHS WILL LIKELY BE IN THE 70S ACROSS THE ENTIRE FORECAST AREA. SATURDAY WILL BE EVEN WARMER WITH A FEW SPOTS APPROACHING THE 80 DEGREE MARK ACROSS EAST-CENTRAL KANSAS AND WEST-CENTRAL MISSOURI. KEPT SOME SLIGHT TO LOW CHANCE POPS IN FOR NORTHERN SECTIONS OF THE FORECAST AREA THURSDAY NIGHT INTO FRIDAY AS A FEW SHOWERS AND THUNDERSTORMS MAY BE TRIGGERED ON THE LEADING EDGE OF LOW LEVEL MOISTURE RETURN. EXPANSIVE HIGH PRESSURE ACROSS THE EASTERN U.S. WILL MAKE IT DIFFICULT FOR ANY FRONTAL PASSAGES UNTIL THE LATTER HALF OF THE WEEKEND. FOR NOW...WILL GO WITH AROUND 30 POPS SATURDAY NIGHT INTO SUNDAY. WITH INCREASED MOISTURE...THERE SHOULD BE DECENT COVERAGE OF STORMS WITH THE APPROACH OF THE FRONT. POPS WILL LIKELY NEED TO BE INCREASED BY LATER SHIFTS...BUT I KEPT THEM A BIT LOW DUE TO THE UNCERTAINTIES REGARDING THE TIMING OF THE FRONT. SAW && .AVIATION... HIGH PRESSURE AT THE SURFACE WILL CONTINUE TO PRODUCE VFR CONDITIONS THROUGH MONDAY. DB && .EAX WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. WFO EAX
