Area forecast discussion, Jul 9, 10:18 AM MST, 4 hours 24 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 1118 AM MDT WED JUL 9 2014 .SHORT TERM...(TODAY THROUGH FRIDAY NIGHT) ISSUED AT 440 AM MDT WED JUL 9 2014 PRETTY QUIET NIGHT WITH JUST SOME SCT MIDLVL CLOUDS PASSING ACROSS THE REGION. THE MONSOONAL RIDGE IS LOCATED NEAR THE FOUR CORNERS REGION WITH THE BEST SUBTROPICAL MOISTURE ACROSS ARIZONA AND NEVADA. STORM CHANCES THIS AFTN WILL BE BETTER THAN YESTERDAY BUT NOT AS GOOD AS THE FOLLOWING DAYS (THURS AND FRI). SFC WINDS WILL BE SOUTH-TO-SOUTHEAST THIS AFTN ACROSS THE PLAINS WITH GOOD LLVL MOISTURE...ESPECIALLY OVER THE NEBRASKA PANHANDLE WHERE DEWPOINTS WILL BE IN THE 55-60F RANGE. THIS RESULTS IN LI VALUES AROUND -5C ACROSS THE PANHANDLE. A WEAK SHORTWAVE MOVING OVER THE NORTHERN PLAINS DURING THE AFTN WILL SERVE TO STRENGTHEN THE FLOW ALOFT SUCH THAT BULK SHEAR WILL BE 40-45 KTS. WITH THESE CONVECTIVE PARAMETERS...A BIT CONCERNED ABOUT A STRONG TO SVR STORM IN THE PANHANDLE. SPC HAS THE DAY1 SLIGHT RISK GRAZING CHEYENNE COUNTY BUT MAINLY TO THE SOUTHEAST OF THE CWA. THINKING THAT COVERAGE OF STORMS WILL BE ISOLATED DUE TO RISING HEIGHTS ALOFT OVER THE COURSE OF THE DAY. MIDLVL RIDGE SHIFTS EASTWARD INTO NEW MEXICO ON THURS. THIS MOVEMENT CAUSES THE MIDLVL FLOW TO HAVE A MORE WEST TO SOUTHWEST COMPONENT WITH INCREASING SUBTROPICAL MOISTURE. IT IS THE MOISTURE PLUME CURRENTLY OVER NEVADA THAT PUSHES ACROSS THE CWA ON THURS AFTN. THE GFS SHOWS PW VALUES RISING TO AROUND 1 INCH EVEN FOR AREAS TO THE WEST OF THE LARAMIE RANGE...SO HAVE MORE OF A SCT COVERAGE OF STORMS. MIDLVL FLOW IS WEAKER ON THURS AND COMBINED WITH LESS SFC INSTABILITY...THE SVR RISK IS QUITE SMALL. THE MODELS CONTINUE TO INDICATE THAT FRI SHOULD SEE THE GREATEST COVERAGE OF STORMS. PW VALUES RISE FURTHER WITH MOST LOCATIONS AT 1-1.3 INCHES. IN ADDITION...A WEAK COOL FRONT/SFC BOUNDARY WILL MOVE OVER THE PLAINS IN THE MORNING WITH LLVL WINDS BECOMING INCREASING EASTERLY AND UPSLOPE. HEAVY RAIN WILL PROBABLY BE THE PRIMARY THREAT WITH THE STORMS ON FRI...ALTHOUGH SMALL HAIL WILL BE POSSIBLE ALSO. .LONG TERM...(SATURDAY THROUGH WEDNESDAY) ISSUED AT 440 AM MDT WED JUL 9 2014 AN INCREASINGLY ACTIVE PERIOD TAKING SHAPE FOR THE UPCOMING WEEKEND AND INTO EARLY NEXT WEEK. THE SRN PLAINS HIGH PRESSURE WILL RETROGRADE WEST TOWARDS THE FOUR CORNERS/GREAT BASIN BY EARLY NEXT WEEK. A SERIES OF SHORTWAVES WILL ROTATE AROUND ITS PERIPHERY AND INTERACT WITH A FAIRLY PERSISTENT INSTABILITY AXIS THAT WILL EXIST ALONG THE FRONT RANGE. MEDIUM RANGE GUIDANCE ARE CONSISTENT IN MOVING THE FIRST SHORTWAVE AND ASSOCIATED WK FRONT THRU THE REGION ON SATURDAY. NORTHEASTERLY UPSLOPE FLOW WILL FOLLOW IN THE LLVLS AIDING CONVECTIVE COVERAGE. MODELS ALSO SHOW THE RRQ OF A H3 JET STREAK SAGGING SOUTH LATE IN THE DAY...WHICH WILL ELEVATE DEEP LAYER SHEAR TO AROUND 40 KNOTS. WOULD SUSPECT AT A MINIMUM A FEW STRONG STORMS ON SATURDAY...WHICH PERHAPS SOME MARGINALLY SEVERE ACTIVITY. CONVECTION WILL LIKELY BECOME ELEVATED AND LINGER SATURDAY NIGHT AND SUNDAY MORNING AS WELL. CONVECTIVE COVERAGE LOOKS A BIT LESS ON SUNDAY...BUT STILL CANT RULE IT OUT GIVEN ACTIVE NORTHWEST FLOW. HIGH PRESSURE CENTER WILL RE-ESTABLISH ITSELF NR THE FOUR CORNERS/ GREAT BASIN MON-TUE. NORTHWEST FLOW WILL BE THE RESULT...ALLOWING FOR A STRONGER FROPA SOMETIME ON MONDAY. THE ECMWF IS THE QUICKEST IN DRIVING IT THRU DURING THE DAYTIME HOURS...WHILE THE GFS HOLDS IT BACK UNTIL MONDAY NIGHT. IN EITHER CASE...CONVECTIVE CHANCES WILL INCREASE AGAIN FOR BOTH MONDAY/TUESDAY. SHOWER/THUNDERSTORM COVERAGE AND ORGANIZATION WILL AGAIN BE AIDED BY THE RRQ OF A H3 JET STREAK DIVING INTO THE CENTER OF THE COUNTRY. HAVE COOLED TEMPERATURES SOME FOR TUE AND WED...BUT STILL LIKELY NOT ENOUGH IF THE STRONGER FROPA IS REALIZED. WEDNESDAY LOOKS TO TURN A BIT DRIER...BUT STEERED THE FORECAST TOWARD CLIMATOLOGY GIVEN TIMING UNCERTAINTIES AT THE FAR RANGES OF THE PERIOD. && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY MORNING) ISSUED AT 1118 AM MDT WED JUL 9 2014 VFR EXPECTED OVERALL THROUGH THE PERIOD WITH WNW FLOW ALOFT OVER THE REGION. A FEW SHOWERS OR TSTMS MAY DEVELOP THIS AFTERNOON THEN END THIS EVENING. && .FIRE WEATHER... ISSUED AT 440 AM MDT WED JUL 9 2014 MINIMAL FIRE WEATHER CONCERNS THROUGH FRIDAY. HUMIDITY VALUES THIS AFTERNOON WILL BE IN THE 15-20 PERCENT RANGE FOR AREAS TO THE WEST OF THE LARAMIE RANGE...HOWEVER WIND GUSTS WILL GENERALLY BE BELOW 20 MPH. ISOLATED THUNDERSTORMS WILL BE POSSIBLE DURING THE AFTERNOON AND EVENING. MOISTURE WILL INCREASE ON THURSDAY AND FRIDAY AND MINIMUM HUMIDITY VALUES WILL RISE TO ABOVE 25 PERCENT. THE INCREASE IN MOISTURE WILL RESULT IN A MORE WIDESPREAD COVERAGE OF SHOWERS AND THUNDERSTORMS ON THESE DAYS. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...NONE.
