A COLD FRONTAL PASSAGE HAS LED TO NORTH WIND SPEEDS OF 15-20. /ISSUED 422 AM CST SUN FEB 7 2016/ AN UPPER LEVEL STORM SYSTEM DIGGING ACROSS THE MIDWEST WILL DELIVER ANOTHER COLD FRONT FOR WEST TEXAS TODAY. THE WINDS WILL GRADUALLY EASE TONIGHT AS SURFACE RIDGING BUILDS INTO THE SOUTHERN HIGH PLAINS AND THE PRESSURE GRADIENT RELAXES. GUIDANCE IS IN RELATIVELY STRONG AGREEMENT THROUGH THE END OF THE WORK WEEK AS A PACIFIC RIDGE AXIS PLODS EASTWARD TOWARD THE INTERMOUNTAIN WEST OVER THE NEXT FIVE DAYS. MONDAY WILL REMAIN IN THE 50S TO LOW 60S AS WINDS MAINTAIN THEIR NORTHERN COMPONENT BEHIND THE COLD FRONT PASSAGE THE DAY BEFORE.
Those areas where the south winds kept temperatures up last night will be much cooler tonight, while the usual cold air drainage locations that dropped into the teens and 20s this morning will actually be a little warmer. Cooler tomorrow for most areas with gusty north and northwest winds. An amplified early week upper level flow pattern will be in place across the CONUS, with an upper ridge over the western states, and an upper level low over the lower Great Lakes with a deep trough over the eastern and southeastern part of the country.
SURFFACE HIGH PRESSURE WILL MOVE INTO THE CENTRAL PLAINS TONIGHT AND MONDAY. WITH LITTLE MOVEMENT FROM THE RIDGE OVER THE GREAT BASIN UNTIL THE END OF THE WEEK. THE ONLY CHANGE HAS BEEN TO DELAY THE PASSAGE OF THE SHORT WAVE TROUGH THIS COMING WEEKEND ONE MORE DAY.

126 PM PST SUN FEB 7 2016 HIGH PRESSURE WILL CONTINUE TO BRING DRY WEATHER TO THE CENTRAL CALIFORNIA INTERIOR FOR THE NEXT SEVERAL DAYS WITH PATCHY NIGHT AND MORNING FOG IN THE SAN JOAQUIN VALLEY. HIGH PRESSURE WILL CONTINUE TO BRING MAINLY CLEAR SKIES TO THE REGION THE NEXT FEW DAYS. FORECAST MODELS MOVE THE HIGH PRESSURE CENTER NORTHEAST INTO SOUTHERN OREGON TONIGHT AND MONDAY AND THEN SLOWLY MOVE THE CENTER OF HIGH PRESSURE TO THE EAST.
100+ KNOT 300 MB WINDS EXTENDED FROM NORTHEAST BRITISH COLUMBIA DOWN INTO WYOMING AT 12Z ON THE BACKSIDE OF A DIGGING MID TROPOSPHERIC TROUGH. SURFACE ANALYSIS AT 19Z HAD A LOW PRESSURE CENTER OVER THE FAR NORTHEAST TIP OF MINNESOTA AND STRONG NORTHWEST FLOW FROM THE DAKOTAS DOWN INTO NEBRASKA. WINDS WILL SLOWLY DECREASE WITH SNOW CHANCES DROPPING THROUGH THE DAY MONDAY AS WELL AS LOW PRESSURE MOVES SOUTHEAST AND OUR PRESSURE GRADIENT DECREASES.
THIS PATTERN DRIFTS EAST DURING THE WEEK AND LEAVES US UNDER THE INFLUENCE OF WARMER WEATHER AND AN UPPER RIDGE WHICH IS EXPECTED TO BUILD TO THE WEST THE SECOND HALF OF THE WEEK.
STRONG HIGH PRESSURE ALOFT AND AT THE SURFACE WILL MEAN SANTA ANA CONDITIONS ACROSS THE REGION THROUGH MIDWEEK.
923 AM MST SUN FEB 7 2016 MORNING VALLEY FOG ACROSS THE LOWER TREASURE VALLEY THROUGH PORTIONS OF THE MAGIC VALLEY ALONG WITH THE BAKER VALLEY SHOULD BEGIN TO BURN OFF LATER THIS MORNING. MODELS STILL SHOWING THE UPPER RIDGE TO AMPLIFY TONIGHT THROUGH MIDWEEK WHICH WOULD KEEP A STRONG INVERSION LOCKED IN PLACE NEXT SEVERAL DAYS. OUTSIDE OF THE LOWER VALLEYS. ALREADY UPDATED THE FORECAST FOR THE FOG THROUGH THE LOWER VALLEYS THIS MORNING. HIGH PRESSURE ALOFT CURRENTLY BUILDING ALONG THE COAST. AS THE UPPER HIGH SHIFTS EAST INVERSION CONDITIONS WILL INTENSIFY IN THE IDAHO VALLEYS WITH AREAS OF FOG AND STRATUS DURING THE NIGHTS AND MORNINGS.
359 PM CST SUN FEB 7 2016 A cold front is moving across the area late this afternoon and evening, and will bring colder temperatures Monday, along with strong and gusty northwest winds. Meanwhile, an upper ridge over the western U.
DRY AND MUCH WARMER THIS WEEK WITH NEAR RECORD AFTERNOON HIGHS. OUR WEATHER WILL CONTINUE TO BE DOMINATED BY A STRONG RIDGE PHASING IN FROM THE WEST. QUITE DRY OTHER THAN SHEAVES OF CIRRUS LEVEL MOISTURE SPREADING NORTHWARD FROM A WEAK LOW DIRTYING UP THE BASE OF THE RIDGE. HIGH PRESSURE WILL BRING DRY CONDITIONS WITH ABOVE AND ABOVE AVERAGE TEMPERATURES THIS WEEK.
HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE ACROSS THE REGION THROUGH THE UPCOMING WEEK. A STRONG UPPER RIDGE REMAINS CENTERED OVER THE WEST COAST THIS MORNING WITH A NORTHWESTERLY FLOW ALOFT OVER THE CWA. THE STRONG NWLY FLOW ALOFT IS TOUCHING THE HIGHEST PEAKS ACROSS THE NRN MTNS WITH GUSTS OVER 60 MPH NOTED. EXPECT A STRONG RADIATIVE NIGHT TONIGHT UNDER CLEAR SKIES WITH THE RIDGE SHIFTING SLOWLY INLAND AND THE FLOW ALOFT DIMINISHING.
A DRY COLD FRONT WILL SWEEP DOWN ACROSS OUR REGION OVERNIGHT.
BRISK NW FLOW ALOFT IN PLACE ACROSS THE STATE AS AN UPPER RIDGE STRENGTHENS OVER THE WESTERN US. THIS BRISK FLOW IS PROVIDING FOR STRONGER WINDS OVER THE HIGHER TERRAIN. WESTERN UPPER RIDGE CONTINUES TO BUILD. MODELS CONTINUE TO SHOW A WEAK COLD FRONT DROPPING DOWN THE E PLAINS AND BACKING TOWARDS THE SOUTHERN FRONT RANGE TODAY. MOORE NORTHWEST FLOW ALOFT WILL GIVE WAY TO RIDGING ALOFT BY MID TO LATE WEEK AS WESTERN U. UPPER RIDGE SHIFTS EASTWARD THROUGH THE PERIOD. THIS SHOULD YIELD TEMPS BACK IN THE 50S TO MID 60S FOR THE LOWER ELEVATIONS. NEXT TROF WILL EITHER GLANCE BY TO THE NORTH ACCORDING TO THE GFS. EITHER WAY SUGGESTS COOLER TEMPERATURES FOR SUNDAY OR MONDAY DEPENDING ON THE TIMING/TRACK OF THE SYSTEM.
WILL KEEP THE HIGH WIND WARNING GOING FOR NOW SINCE RAPID CITY IS CURRENTLY EXPERIENCING GUSTS OVER 60 MPH AND SKIES HAVE CLEAR ACROSS DAWES AND NRN SIOUX COUNTIES. WIND SPEEDS SLOWLY DECREASING ACROSS OUR SOUTHERN LARAMIE RANGE AS GRADIENTS RELAX SOMEWHAT AND THUS WILL LIKELY BE ABLE TO CANCEL THE HIGH WIND WARNING THERE. EXPECT SURFACE WINDS TO DECREASE AS THE LOW LEVELS OF THE ATMOSPHERE DECOUPLE.
WITH HIGH PRESSURE IN CONTROL, THERE IS LITTLE OF MAJOR CONCERN THIS MORNING.
THIS COULD CHANGE AS TEMPERATURES WILL BE NEAR FREEZING AND JUST A FEW DEGREES CAN MEAN THE DIFFERENCE BETWEEN RAIN AND SNOW.
334 PM EST SUN FEB 7 2016 CURRENTLY - COOL CONDITIONS PREVAIL ACROSS THE ISLAND CHAIN IN WAKE OF THIS MORNINGS COLD FRONT. TEMPERATURES ARE IN THE LOW TO MID 60S WITH DEW POINTS NEAR 50.

SOMEWHAT WARMER CONDITIONS CAN BE EXPECTED TOMORROW.
228 PM CST SUN FEB 7 2016 LATEST SURFACE OBSERVATIONS SHOW NORTHERLY WINDS UP TO AROUND 15 TO 20 MPH BEHIND A WEAK COLD FRONT AND SLIGHTLY COOLER TEMPERATURES THAN 24 HOURS PRIOR. ON THE SYNOPTIC SCALE A BROADENING/DEEPENING TROUGH EXTENDED FROM THE UPPER MIDWEST INTO THE CENTRAL PLAINS AND WAS PROGRESSING SOUTHEASTWARD. AS THE TROUGH CONTINUES EASTWARD THROUGH MID WEEK MID LEVEL HEIGHT RISES WILL OCCUR.

104 PM EST SUN FEB 7 2016 CLEARING SKIES THIS AFTERNOON AS THE LOW PRESSURE SYSTEM OFF THE COAST MOVES TO THE NE. A COLD FRONT WILL PASS THROUGH LATE MONDAY.
TEMPERATURES WERE RUNNING COOLER THAN EXPECTED UNTIL MID MORNING. LATEST SATELLITE IMAGERY SHOWED AN UPPER TROUGH EXITING EAST OF THE CWA. THIS HAD TAKEN THE HIGH CLOUDS EAST OF THE CWA AS SHORT WAVE RIDGING BUILDS ACROSS THE ARKLAMISS. A CLOSED UPPER LOW WILL SWING TOWARD THE GREAT LAKES AND DEVELOP A STRONG DEEP UPPER TROF OVER THE EASTERN CONUS. THE UPPER TROUGH WILL QUICKLY PUSH A COLD FRONT THROUGH THE REGION BY EARLY MONDAY. EXPECT SOME COLD STRATOCU TO PUSH DOWN INTO THE NORTHEAST PORT OF CWA FROM AROUND THE LARGE CLOSED LOW. HIGHS ON MONDAY WILL RANGE FROM THE MIDDLE 40S TO THE LOWER 50S.
High pressure will dominate over western Montana and central Idaho for much of this week. Locations that do see fog or stratus develop will likely see cooler daytime temperatures than currently reflected in the forecast.
THE MAIN SHORT TERM ISSUE WILL BE A COLD FRONT PASSING THROUGH THE CWA OVERNIGHT.
