THE BAROCLINIC ZONE WILL REMAIN IN PLACE TONIGHT AS ANOTHER DISTURBANCE RIDES THE RIDGE ON THE HEELS OF THIS MORNINGS ONE. BUT THIS WILL BE A CLASSIC INVERSION IN WHICH SURFACE TEMPERATURES LIKELY REMAIN BELOW FREEZING.
531 AM CST Fri Feb 6 2015 Rising temperatures are the main story today and Saturday with a broad upper ridge building into the area. Models have really struggled to adequately resolve mixing heights in similar ridging patterns this season, and thus believe model guidance continues to be several degrees too cool with surface temperatures. An even warmer surge of 925 hPa temps on Saturday should allow temperatures to rise about 10 degrees warmer than Friday's readings with upper 60s/near 70 south of the Missouri River and mid/lower 50s to the north. Southerly winds gliding over the snow and dewpoints rising above freezing will likely favor areas of advection fog both nights.
HIGH PRESSURE WAS IN PLACE ACROSS THE REGION THIS MORNING AND WILL REMAIN ACROSS THE REGION THROUGH THE DAY. THE RIDGE AXIS WILL EXTEND BACK INTO THE I-59 CORRIDOR AND ALLOW FOR THE BEST RAD COOLING CONDITIONS. THIS WILL SUPPORT NEAR OR JUST BELOW FREEZING TEMPS FOR THE EASTERN CWA.

DETERMINISTIC MODELS SHOW THE UPPER LEVEL RIDGE FLATTENING SOME AND SWLY WINDS ALOFT BECOMING NEARLY ZONAL BY THE AFTERNOON. AFTERNOON TEMPS SHOULD HAVE LITTLE PROBLEM REACHING THE LOW/MID-70S ON THE PLAINS AND UPPER 40S- 50S IN THE HIGH COUNTRY. RESULTING IN GUSTIER W-SWLY WINDS ON THE MTN RIDGES AND HIGHER FRONT RANGE FOOTHILLS.
634 AM EDT SUN APR 5 2015 HIGH PRESSURE WILL SLIDE EAST TO THE MID ATLANTIC COAST BY THIS EVENING BUT IT WILL STILL BE STRONG ENOUGH TO PROVIDE MOSTLY CLEAR SKIES AND DRY CONDITIONS FOR OUR AREA. HIGH TEMPERATURES TODAY WILL BE IN THE LOW TO MID 60S. 05Z RAP WAS AROUND 3 TO 4 DEGREES WARMER THAN THE REST OF THE GUIDANCE.
CLOSED LOW AND THE DEPARTING RIDGE WILL BRING A SMALL CHANCE OF SHOWERS INTO THE WESTERN COUNTIES IN SOUTHEAST MISSOURI TOWARD SUNSET ON SUNDAY. THE WARM ADVECTION SCENARIO WILL CONTINUE IN THE WARM SECTOR THROUGH MONDAY NIGHT IN ADVANCE OF THE NEXT COLD FRONT LATER IN THE WEEK.

QUASI-ZONAL UPPER PATTERN OVER THE CONUS TODAY WITH AN UPPER TROUGH ENTERING THE WEST COAST MONDAY (GFS DETERMINISTIC) CONSISTENT WITH ONSHORE FLOW OVER THE CWA/MSA DRG THE PERIOD. DISSIPATING WARM FRONT/MSTR MAY CONTRIBUTE TO ISOLD/SCT CONVECTION TODAY.
THESE SHOWERS WERE LIKELY IN THE EARLY STAGES OF DEVELOPMENT ALONG A WARM FRONT. MODELS STILL SHOW THAT THE HIGHEST QPF WILL OCCUR NORTH OF A BURNS-BOISE-FAIRFIELD LINE. SNOW LEVELS BETWEEN 3000 AND 4000 FEET THIS MORNING IN THESE AREAS WILL RESULT IN A DUSTING TO AN INCH OF SNOW IN THE LOWER ELEVATIONS FROM BURNS TO BAKER CITY. THE SHOWERS OVERNIGHT WILL BE SUPPORTED BY A SHORT WAVE WHICH MOVES THROUGH THE PACNW AS IT PEELS AWAY FROM THE PARENT COASTAL UPPER LOW. SHOWERS WILL LINGER ACROSS THE NORTH ON MONDAY WHILE DRIER AIR ASSOCIATED WITH WEAK UPPER RIDGING MOVES IN AHEAD OF THE MAIN UPPER LOW AS IT HANGS JUST OFF THE WEST COAST.
