1146 PM CDT WED MAR 23 2016 SHOWERS AND THUNDERSTORMS WERE DEVELOPING ALONG A COLD FRONT THAT WAS MOVING THROUGH THE CENTRAL PART OF THE STATE AT 0430Z. TWEAKED THE TIMING OF THE FRONTAL PASSAGE AFTER COMPARING THE CURRENT RADAR WITH THE HIGH RESOLUTION MODELS. DEEP LOW PRESSURE WAS LOCATED OVER NE KANSAS. A DEEP UPPER LOW WAS SPINNING OVER THE KANSAS/NEBRASKA WITH A 90-100 KT JET TO THE E-SE OF THE LOW. THE SPEED MAX ON THE EAST SIDE OF LOW WILL MOVE NE TONIGHT AND SE TX WILL LIE IN A RIGHT REAR QUAD BETWEEN 06-12Z WHICH IS THE SAME TIME THE COLD FRONT WILL BE CROSSING THE AREA. CONDITIONS SHOULD DRY OUT QUICKLY ON THURSDAY IN THE WAKE OF THE FRONT WITH SLIGHTLY COOLER TEMPS.
Between 05Z-07Z, a cold front will drop south through the terminals, resulting in a northerly wind shift, and gusts up to around 30KT possible. /issued 215 PM CDT WED MAR 23 2016/ Upper pattern has a strong upper level closed low swinging across the Rockies today and onto the plains.
CLOUD COVER OUT OF THE SW HAS ALSO MANAGED TO SPREAD OVER MUCH OF THE AREA AS AN UPPER LOW/TROUGH AXIS OVER THE MID PLAINS TAKES AIM AT THE MIDWEST/OH VALLEY STATES. WITH READINGS PREDOM IN THE LOWER/MID 60S. WELL ADVERTISED COLD FRONT ASSOCIATED WITH THE UPPER TROUGH PATTERN OUT W WILL BEGIN TO GRADUALLY TRANSLATE EWD AS THE LATE MORNING HRS THU PROGRESS.
THE LATE EVENING LOCAL SOUNDING HAS SHOWN A MARKED INCREASE IN MOISTURE IN THE LOWEST LAYERS OF THE TROPOSPHERE OVER THE PAST 12 HOURS. THE HIGH TEMPERATURE IN KEY WEST WAS 62 DEGREES.

COUNTIES THAT REMAIN UNDER THE HIGH WIND WARNING ARE RUSSELL. OTHERWISE COOLER BELOW NORMAL TEMPERATURES WILL SPREAD ACROSS KANSAS ON THURSDAY IN THE WAKE OF THE DEPARTING UPPER LEVEL SYSTEM.
WINDY CONDITIONS CONTINUE ACROSS THE AREA TODAY AS THE SURFACE PRESSURE GRADIENT REMAINS STRONG AHEAD OF THE APPROACHING TROUGH AND COLD FRONT. DID NOT ISSUE A WIND ADVISORY JUST YET AS THE WINDOW FOR STRONGER WINDS LOOKS TO BE MID MORNING TO MID AFTERNOON AHEAD OF THE COLD FRONT. THE NAM HAS A PUSH OF PRECIP IN THE WARM SECTOR EARLY IN THE DAY AND A SECONDARY RUN OF PRECIP WHEN THE COLD FRONT MOVES THROUGH.
CURRENTLY A COLD FRONT IS POSITIONED OVER CDS AND PVW AND WILL QUICKLY PUSH THROUGH TURNING WINDS TO THE NORTH AROUND 25 KNOTS. THE COLD FRONT WAS MOVING THROUGH THE SOUTHERN TEXAS PANHANDLE.

LIMITING THUNDER TO KVCT AREA (VCTS AT KLRD) AND JUST GOING WITH SHOWERS AT KALI AND KCRP (THINK CAP WILL BE TOO STRONG ONCE THE CONVECTION GETS FAR ENOUGH SOUTH AND HITS THE CAP AND THE WARMER AIR ALOFT. THE WINDS CONTINUE TO REMAIN ON THE BREEZY SIDE LATE THIS EVENING HOWEVER THEY SHOULD GRADUALLY DECREASE AHEAD OF THE ENSUING COLD FRONT. HOWEVER SOME JET STREAK INFLUENCE MAY OCCUR LATE TONIGHT IN TANDEM WITH THE COLD FRONT PASSAGE HELPING TO PRODUCE NUMEROUS SHOWERS AND EMBEDDED THUNDER.
947 PM EDT WED MAR 23 2016 HIGH PRESSURE WILL REMAIN OVER THE WESTERN ATLANTIC THROUGH THURSDAY.
The cold front will then begin to overtake the dry line later this evening and will tend to enhance low-level convergence. Changing gears, we have gone ahead and cancelled the High Wind Warning, Wind Advisory, and Red Flag products. We will still have to watch winds for later this evening and the early overnight period behind that dry line and cold front as good pressure rises kick in and we see better mixing develop. Due to thin nature of the lower tropospheric moisture, mixed layer capes will be mitigated to 400 j/kg or less. We expanded the Wind Advisory eastward into the Highway 65 corridor. Tonight's frontal passage will bring a colder airmass to the Ozarks, as temperatures fall into the lower 40s tonight.
EXPECT REMAINING CLOUDS TO DIMINISH OVERNIGHT AS THE UPPER LEVEL RIDGE OVER NEVADA EXPANDS NORTHWARD INTO THE REGION.
