Area forecast discussion, Apr 23, 3:49 PM MDT, 22 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 349 PM MDT THU APR 23 2015 .SHORT TERM...(THIS EVENING THROUGH FRIDAY) ISSUED AT 340 PM MDT THU APR 23 2015 ...STILL SOME SEVERE POTENTIAL OVER THE FAR EASTERN PLAINS THIS EVENING... ATMOSPHERE IS STILL RIPE OUT EAST FOR STRONG TO SEVERE STORMS. THERE IS SUFFICIENT SHEAR AND PLENTY OF ELEVATED CAPE. INHIBITING FACTORS SO FAR...I THINK...INCLUDE RELATIVELY COOL SURFACE TEMPERATURES AND NOW AN EXPANDING HIGH CLOUD SHIELD FROM ELEVATED CONVECTION THAT INITIATED ALONG AND NEAR THE MOUNTAINS EARLIER. BUT...CERTAINLY NOT OUT OF THE WOODS YET. AS HIGHER LEVEL CONVECTION WORKS EAST...IT WILL WORK INTO A PROGRESSIVELY MORE MOIST AND MORE SHEARED ENVIRONMENT...AND ALSO AN ENVIRONMENT WITH CONVECTIVE OUTFLOW BOUNDARIES AVAILABLE. THESE COULD STILL BE ENOUGH TO TRIGGER SOME SUBSTANTIAL CONVECTION A LITTLE LATER THIS AFTERNOON THROUGH THE EVENING. HI RES MODELS STILL DEPICT THIS...EVEN THROUGH MID EVENING. PRIMARY THREATS WILL INCLUDE 1 INCH HAIL AND 60 MPH WINDS WITH A TORNADO NOT OUT OF THE QUESTION. SPC IS CURRENTLY AT A 40 PERCENT CHANCE OF A SEVERE THUNDERSTORM WATCH FOR THE FAR EASTERN COLORADO COUNTIES AND HOLDING. THERE HAS BEEN NO CHANGE IN THIS STATUS FOR A FEW HOURS NOW. ELSEWHERE... ISOLATED TO SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WITH PRIMARY THREATS OF LIGHTNING AND GUSTY WINDS TO AROUND 50 MPH. ELEVATIONS ABOVE 10000 FEET COULD SEE LOCAL SNOW ACCUMULATIONS OF AN INCH OR 2. ON FRIDAY...ANOTHER SHORTWAVE WILL MOVE EAST ACROSS THE FORECAST AREA...TRIGGERING ANOTHER ROUND OF AFTERNOON AND EVENING CONVECTION. CONVECTION WITH THIS NEXT WAVE IS ACTUALLY LOOKING A BIT MORE WIDESPREAD THAN IT IS TODAY. HOWEVER...THE SEVERE THREAT LOOKS DECREASED AS CONSIDERABLY LESS SHEAR AND LOW LEVEL MOISTURE LOOKS AVAILABLE. PRIMARY THREATS LOOK TO BE LIGHTNING AND WIND GUSTS TO AROUND 50 MPH. .LONG TERM...(FRIDAY NIGHT THROUGH NEXT THURSDAY) ISSUED AT 340 PM MDT THU APR 23 2015 RELATIVELY ACTIVE METEOROLOGICAL PATTERN EXPECTED TO CONTINUE OVER THE FORECAST DISTRICT INTO EARLY NEXT WEEK WITH PRIMARY METEOROLOGICAL ISSUES BEING POPS(INCLUDING THE POTENTIAL FOR LOCALLY HEAVY PRIMARILY HIGHER TERRAIN SNOW AND PRECIPITATION AMOUNTS) AS WELL AS TEMPERATURES. RECENT FORECAST MODEL SOUNDINGS...COMPUTER SIMULATIONS ...METEOROLOGICAL PARAMETERS AND PV ANALYSIS SUGGEST THAT INITIAL UPPER SYSTEM CENTERED OVER NORTHWESTERN KANSAS AT 00Z SATURDAY SHIFTS INTO IOWA BY 12Z SATURDAY. THEN BRIEF TRANSITORY UPPER RIDGING MOVES OVER CWFA SATURDAY IN ADVANCE OF VIGOROUS UPPER SYSTEM THAT IS PROJECTED TO BE CLOSING OFF OVER NORTHERN ARIZONA BY 15Z SUNDAY BEFORE SHIFTING ACROSS NORTHERN NEW MEXICO FROM LATER SUNDAY INTO SUNDAY NIGHT AND THEN MOVING INTO THE TEXAS PANHANDLE REGION BY 18Z MONDAY BEFORE MOVING INTO SOUTHEASTERN OKLAHOMA BY TUESDAY MORNING. THE PROJECTED SUNDAY INTO MONDAY STORM SYSTEM HAS THE POTENTIAL OF PRODUCING SIGNIFICANT PRECIPITATION(INCLUDING SIGNIFICANT ACCUMULATING HIGHER ELEVATION SNOW). WFO PUEBLO WILL CONTINUE TO MONITOR THE DEVELOPMENT...STRENGTH AND TRACK OF THIS POTENTIALLY VIGOROUS STORM SYSTEM CLOSELY. THEN...DEVELOPING UPPER RIDGING SHOULD ALLOW FOR DRIER AND WARMER CONDITIONS OVER THE FORECAST DISTRICT FROM TUESDAY INTO NEXT THURSDAY. AT THIS TIME...IT APPEARS THAT THE COOLEST TEMPERATURES DURING THE LONGER TERM SHOULD BE NOTED FROM SUNDAY INTO TUESDAY MORNING...WITH WARMEST CONDITIONS ANTICIPATED FROM WEDNESDAY INTO NEXT THURSDAY. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z FRIDAY EVENING) ISSUED AT 340 PM MDT THU APR 23 2015 UPPER LEVEL DISTURBANCES WILL TRIGGER MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THROUGH THE EVENING AND AGAIN FRIDAY AFTERNOON AND EVENING. PRIMARY CONCERNS THIS EVENING WILL BE LIGHTNING AND WIND GUSTS TO AROUND 50 MPH. HOWEVER...STORMS OVER THE FAR EASTERN PLAINS COULD CONTAIN 1 INCH DIAMETER HAIL AND DAMAGING WINDS IN EXCESS OF 60 MPH. ON FRIDAY...PRIMARY THREATS ALL AREAS WOULD APPEAR TO BE LIGHTNING AND WIND GUSTS TO AROUND 50 MPH. GENERALLY VFR FLIGHT CONDITIONS ARE EXPECTED TO PREVAIL OVER THE NEXT 24 HOURS...EXCEPT IN AREAS OF SHOWERS AND THUNDERSTORMS WHERE CONDITIONS WILL LOWER TO MVFR/IFR/LIFR. SHOWERS AND THUNDERSTORMS COULD TRACK ACROSS ANY OF THE TAF SITES THIS EVENING...SO WILL CARRY VCTS UNTIL 02Z ALL 3 SITES. THE SAME SCENARIO IS IN STORE FOR FRIDAY SO VCTS WILL LIKELY BE ADDED TO ALL 3 SITES FOR TOMORROW AFTERNOON WITH THE NEXT TAF ISSUANCE. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. &&
