ISOLATED SHOWERS HAVE DEVELOPED ACROSS CNTRL INTO NERN PNHDL. && .DISCUSSION... LATE AFTN AND TONIGHT...LATE AFTN PSBL TSTMS FOR AREAS WEST OF HWY 61 AND NORTH OF I80. WILL ALSO MONITOR SWRN AREAS AS WARM FRONT INTO EXTREME SWRN NEBR COULD ACT AS A WEAK FOCUS. A LEAD DISTURBANCE WITH THE NOSE OF H3 JET WILL MOVE IN AS SURFACE FRONT ACTS AS MAIN FOCUS. SHEAR WILL BE STRONG NEAR 60 KTS. THIS ACTIVITY SHOULD WANE THIS EVENING AWAITING BETTER FRONTOGENESIS AFT MIDNIGHT ACROSS THE NORTHWEST. SERN AREAS LOOK DRY DUE TO LACK OF FOCUS AND STORM MOTION NORTHEAST AT 20 MPH. COLD FRONT SHOULD PUSH ACROSS ALL BUT FAR ERN FORECAST AREA TONIGHT. WILL KEEP 20 TO 30 POPS FOR SHOWERS AND THUNDERSTORMS ACROSS NWRN HALF OVERNIGHT. MOISTURE WILL BE LIMITED. SHEAR WILL BE STRONG (60 KTS ACROSS NW).

TIMING OF FRONT BY LATE AFTN FCST TO REACH NEAR FALLS CITY NEBR THROUGH DODGE CITY KS. ACROSS WRN NEBR...WEAK FRONTOGENESIS ALOFT ALONG WITH MODESTLY STEEP LAPSE RATES OF 7-7.5C/KM SHOULD GENERATE ISOLATED TO WIDELY SCT SHOWERS AND TSTMS. UNFAVORABLE LEFT ENTRANCE REGION OF H3 JET SUGGESTS STRONG CONVECTION UNLIKELY. LOW CHC POPS EAST OF HWY 83 WITH ONLY SLIGHT CHC WEST THURSDAY NIGHT. HIGHS THURSDAY CLOSE TO WARMER MAV GUIDANCE FROM THE MID 60S FAR SERN AREAS TO THE MID/UPPER 50S NORTHWEST HALF.

ON FRIDAY AND INTO THE WEEKEND...THE LARGE UPPER LOW WILL ROTATE ACROSS NRN NORTH DAKOTA/SRN MANITOBA FRIDAY...THEN WILL ACCELERATE NORTHEAST ACROSS ONTARIO CANADA OVER THE WEEKEND. A BROAD TROUGH WILL PERSIST ACROSS THE INTERMOUNTAIN WEST AND NRN/CNTRL PLAINS HOWEVER AS DISTURBANCES DROP THROUGH THE NRN ROCKIES. THIS WILL KEEP HIGHS ABOUT 10 DEGREES BELOW NORMAL FRIDAY THROUGH SUNDAY WITH A SLIGHT CHC FOR SHOWERS THROUGH THE PERIOD. MOST OF THIS PERIOD SHOULD BE DRY HOWEVER WITH MOST ACTIVITY DIURNALLY DRIVEN TOWARDS AFTN AND EVENING SHOWERS. FOR MONDAY THROUGH WEDNESDAY...MEDIUM RANGE MODELS DIFFER WITH THE ECMWF DROPPING AN UPPER TROUGH INTO THE PAC NW MONDAY WHILE THE GFS SHOWS A TRANSITORY RIDGE EXTENDING FROM THE PAC NW NORTH THROUGH BRITISH COLUMBIA. WHILE SHOWER CHCS AND COOLER TEMPS NEAR 60 LOOK IN AGREEMENT MONDAY...THE ECMWF INDICATES A MUCH WARMER SOLUTION WITH HIGHS INTO THE 70S TO LOWER 80S TUESDAY WHILE THE GFS COOLER WITH UPPER 50S/LOWER 60S TUESDAY AND MID/UPPER 60S WEDNESDAY. USING HPC GUIDANCE CONTINUES TO WORK WELL...WHICH LOOKS TO BE A BLEND OF THE TWO SOLUTIONS....ALTHOUGH WEIGHTED TOWARD THE COOLER GFS. ALSO WENT DRY FOR TUESDAY/WED. && .AVIATION... VISUAL FLIGHT RULES ARE EXPECTED THROUGH 00Z AT TERMINALS KLBF AND KVTN THIS EVENING. AROUND 00Z THE COLD FRONT WILL PUSH EAST WITH MODELS GENERATING A SPREAD IN AVAILABLE MOISTURE IN THE BOUNDARY LAYER. NAM INCREASING MODEL RH WITH THE PASSAGE OF THE FRONT BUT MAY BE OVERDOING IT AS DEWPOINTS REMAIN AOB 40 FURTHER WEST OF THE PANHANDLE. BY 06Z MODEL SOUNDINGS AND TIME HEIGHTS PROJECT CEILINGS DEVELOPING AOB 5KFT. TAFS CURRENTLY HOLDING TO VISUAL FLIGHT RULES BUT WILL BE REACCESSED AS COLD FRONT MOVES EAST AND AVAILABLE MOISTURE BECOMES BETTER DEFINED WHILE ISOLATED HIGH BASED THUNDERSTORMS DEVELOP THIS EVENING. IF MODELS ARE ON TRACK THERE COULD BE A 6 HOUR PERIOD WHERE CEILINGS COULD DROP AOB MARGINAL VISUAL FLIGHT RULES FROM 06Z TO 12Z AT BOTH TERMINALS...THEN VISUAL FLIGHT RULES BEYOND ON THURSDAY. && .LBF WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS/DISCUSSION...ROBERG AVIATION...KECK
