(TODAY THROUGH FRIDAY) ISSUED AT 245 AM CDT WED OCT 22 2014 MAIN CONCERN WILL BE THE TIMING OF SURFACE COLD FRONT AND ASSOCIATED PRECIP ACROSS THE AREA TODAY AND TONIGHT. SURFACE TROUGH WAS LOCATED OVER THE WESTERN PANHANDLE OF NEBRASKA AT 07Z WITH RADAR SHOWING A BAND OF PRECIP ON THE BACK SIDE OF THE TROUGH IN ADVANCE OF A COLD FRONT FROM WESTERN SOUTH DAKOTA INTO NORTHEAST WYOMING. SHORT RANGE MODELS TRACK THE SYSTEM INTO CENTRAL NEBRASKA BY 18Z EASTERN NEBRASKA BY 00Z. SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED TO SPREAD EAST TODAY IN ADVANCE OF THE FRONT WITH POPS INCREASING ACROSS EASTERN NEBRASKA BETWEEN 18Z-00Z. MODELS CONTINUE TO SHOW A STEADY TRACK OF THE SYSTEM TO THE EAST TONIGHT WITH RAIN ENDING OVER EASTERN PARTS OF THE FORECAST AREA BY 12Z THURSDAY WITH CLEARING FOLLOWING BEHIND THE FRONT. FAIR AND MILD CONDITIONS EXPECTED THURSDAY INTO FRIDAY AS UPPER RIDGE BUILDS INTO THE CENTRAL PLAINS. .LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY) ISSUED AT 245 AM CDT WED OCT 22 2014 DRY AND MILD CONDITIONS CONTINUE INTO THE FIRST PART OF THE EXTENDED PERIOD THROUGH THE WEEKEND. MODELS THEN MOVE ANOTHER COLD FRONT INTO THE REGION SUNDAY NIGHT WITH THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS INTO MONDAY DEPENDING ON LOCATION AND TIMING OF THE FRONT AND UPPER TROUGH. GFS GIVES THE AREA HIGHER POPS AS IT STALLS FRONT OVER THE AREA ON MONDAY WHILE EURO MORE PROGRESSIVE IN TAKING THE FRONT FURTHER SOUTH AND EAST OF THE AREA WITH LOWER POPS DURING THIS TIME. CONTINUED TO STAY GUIDANCE AT THIS POINT AND MAINTAIN LOW POPS ON MONDAY INTO MONDAY NIGHT. TEMPERATURES TURN COOLER BEHIND THE FRONT MONDAY AND TUESDAY.
