THIS IS ALL ADVANCING INTO CENTRAL PA BUT ENCOUNTERING RELATIVELY DRIER AIR EAST NORTHEAST OF H5 RIDGE AXIS. COLD AIR DAMMING WILL BECOME MORE PRONOUNCED AND STRENGTHEN OVERNIGHT AS HIGH PRESSURE CHANNELS TO THE EAST OF THE APPALACHIANS. 00 INCHES ACROSS THE SOUTH-CENTRAL RIDGES INTO THE LWR SUSQ. WITH LOW PRESSURE DEVELOPMENT OFF THE MID ATLANTIC COAST BY TUESDAY MORNING. LOW PRESSURE SHOULD BE PULLING EAST OF THE AREA EARLY TUESDAY. BOTH THE GEFS/ECMWF DEVELOP A REX BLOCK BY WED WITH THE UPPER-LEVEL LOW OVER THE NRN PLAINS/WRN GLAKES AND THE HIGH JUST SOUTH OF HUDSONS BAY. THERE IS PRETTY GOOD OVERALL AGREEMENT IN A COOLER END OF THE WEEK. A SE TO EAST FLOW OF COOL AIR FROM HIGH PRESSURE OVER EASTERN CANADA WILL PREVAIL INTO TUESDAY MORNING. AS HIGH PRESSURE BUILDS OVER NEW ENGLAND.
601 AM EDT MON MAR 14 2016 HIGH PRESSURE WILL MOVE EAST ACROSS THE MARITIMES TODAY.
MULTIPLE COLD FRONTS AND VARIOUS CHANCES OF RAIN. WHICH SHOULD SEND A COLD FRONT SOUTH THROUGH NORTH AND CENTRAL TEXAS ALSO ON TUESDAY. TEMPERATURES WILL ONLY FALL SLIGHTLY AS THE WEAK COLD FRONT MOVES THROUGH THE AREA TUESDAY.
310 AM EDT MON MAR 14 2016 WEAK LOW PRESSURE WILL DRAG A WARM FRONT NORTHEAST ACROSS THE AREA EARLY TODAY.
AS A LARGE RIDGE OF HIGH PRESSURE BUILDS ACROSS THE SOUTHERN AND SOUTHEASTERN CONUS AND WINDS SHIFT BACK TO A SOUTHERLY DIRECTION.

GUSTY WINDS WILL PERSIST THROUGH THE FAVORED PASSES AND CANYONS THROUGH THIS EVENING AS THE LOW PRESSURE SYSTEM EXITS THE REGION. A RIDGE OF HIGH PRESSURE WILL BUILD AND BRING DRY AND WARMER WEATHER. AS THE LOW PRESSURE SYSTEM EXITS THE AREA TODAY. HIGH PRESSURE WILL RETURN TO THE REGION AND GRADUALLY BUILD FOR THE REST OF THE WEEK. EXPECT GENERALLY PLEASANT WEATHER WITH HIGHS MAINLY IN THE 70S AND LOWS MAINLY IN THE 40S IN THE LOWER ELEVATIONS DURING TUESDAY THROUGH AT LEAST THE END OF THE WEEK.
239 AM MDT MON MAR 14 2016 LATEST UPPER AIR DATA SHOW A CLOSED LOW OVER OKLAHOMA WITH A LARGER SCALE TROUGH OVER THE PACIFIC NORTHWEST. AT THE SURFACE A TROUGH WAS MOVING THROUGH THE TRI-STATE AREA. BEHIND THE TROUGH NORTHWEST WINDS WERE GUSTING 30-40 MPH. LOWS WILL NOT BE AS WARM AS LAST NIGHT DUE TO THE LOWER DEW POINTS. MONDAY WINDS WILL TURN TO THE SOUTHWEST AHEAD OF A COLD FRONT THAT WILL MOVE THROUGH DURING THE EVENING. THE LOW DEW POINTS OVER THE WEST TODAY WILL STILL BE THERE MONDAY.

237 AM CDT MON MAR 14 2016 Water Vapor loops depict the upper Low rotating over Northern Arkansas. Isolated thunderstorms/heavy rain are possible, but the mdt risk of rainfall exceeding FFG remains to the south of the Low track, i. This should be followed by dry wx, despite the SPC issued day 2 marginal risk, as the moisture associated with the next low pressure system looks to stay just to our north (in the slgt risk zone).
130 AM EDT MON MAR 14 2016 WARM TEMPERATURES WITH PERIODIC SHOWER CHANCES ARE EXPECTED FOR MUCH OF THE WEEK WITH A SERIES OF CROSSING LOW PRESSURE AREAS. RESULTING IN UPPER RIDGING INCREASING OVER OUR AREA. WHILE THE UPPER LOW WILL REMAIN LARGE PARKED OVER THE UPPER MIDWEST THROUGH MID-WEEK.
A STRONG TROUGH WILL MOVE THROUGH TODAY. THIS HELPED PRODUCE PLENTY OF PRECIPITATION YDAY AND PUSHED A COLD FRONT THROUGH OVERNIGHT. TEMPS WILL BE COOLER TODAY AND TOMORROW. WITH THE TROUGH AXIS PASSING THROUGH THE CWA TODAY. WINDS WILL SLACKEN OFF TONIGHT AS RIDGING BEGINS TO BUILD IN ALOFT.
337 AM CDT MON MAR 14 2016 Flat ridge with zonal flow in the upper levels will give way to a broad upper trough over the center of the country Tuesday. Additional lobes of the trough will rotate down keeping the area in a fairly consistent pattern aloft through the rest of the week. By this weekend a ridge will strengthen over the western US with the region on the east edge of it. Have continued the High Wind Warning this afternoon for the Guadalupe Mountains with a Wind Advisory for the surrounding plains.

Showers and isoalted thunderstorms will move into the High Plains today, reaching far southwest Kansas late in the afternoon. As far as temperatures go, highs will be well above average with highs into the lower 90s along and east of highway 283. A deepening leeside trough at the surface will yield somewhat strong afternoon winds of 15 to 25 mph, especially along/west of Highway 83. That will likely exit late in the afternoon, but there will likely still be some surface convergence along the quasi-stationary lee trough along the southeastern CO/southwestern KS border.
