We'll see the rain exit somewhat quickly within a couple hours as the upper low progresses towards eastern Tennessee and pushes dry air back into the area. We'll see temperatures falling again with Saturday morning lows in the lower 30s northwest to mid 30s southeast.
High pressure centered across the Northern Rockies and Montana will maintain mostly clear, dry and mild conditions across the region through the weekend.
High pressure will remain over the Interior West through the weekend.
THIS DUE TO THE WARM TEMPERATURES ACROSS THIS REGION ALONG WITH AVAILABLE GULF MOISTURE BY THE SOUTHERLY LOW LEVEL FLOW AROUND THE FRONT SIDE OF AN INVERTED TROUGH OF LOW PRESSURE FROM SOUTH CENTRAL TEXAS ACROSS EAST AND NORTHEAST TEXAS AND PARTS OF SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS. ALSO A SMALL SCALE SHORT WAVE EMBEDDED IN THE FLOW AROUND THE TOP OF A FLAT RIDGE OF HIGH PRESSURE ALOFT OVER MEXICO AND SOUTH TEXAS. AND INTO THE BACK SIDE OF A RIDGE OF HIGH PRESSURE ALOFT FROM THE NORTHERN GULF INTO THE GREAT LAKES AREA. BUT INCREASED LATE AS A SHORT WAVE TROUGH ROUNDING THE BASE OF A LARGE UPPER LOW SPINNING OVER THE ROCKIES SHIFTS ACROSS OKLAHOMA AND NORTH TEXAS.
THIS ADJUSTEMENT OCCURRING IN RESPONSE TO THE MAIN UPPER TROUGH OVER NRN NM SHOWING EWD MOVEMENT PER WATER VAPOR IMAGERY THE LAST COUPLE HOURS. TROUGH AXIS SHOULD SHIFT TO THE EAST OF THE FCST AREA AROUND 06Z WITH HIGH CHANCE TO LIKELY POPS ERN HALF OF THE FCST AREA APPROPRIATE UNTIL THEN. NOT MUCH UPPER SUPPORT EVIDENT WITH A SHORT WAVE TROUGH PROGGED TO SEWD THROUGH THE MEAN FLOW FROM SRN COLORADO TWD THE PANHANDLE. A SECONDARY COLD FRONT WILL PUSH THROUGH TOMORROW NIGHT AS A SHORT WAVE ROTATES AROUND THE BACKSIDE OF THE MUCH LARGER UPPER LEVEL LOW ACROSS THE MIDWEST.
LARGE UPPER LEVEL CLOSED LOW CONTINUES TO MIGRATE EASTWARD THROUGH THE CENTRAL PLAINS WITH THE FORECAST AREA NOW MAINLY UNDER THE INFLUENCE OF QUAZI-ZONAL FLOW ALOFT.

414 PM CDT TUE APR 19 2016 THE SYNOPTIC SETUP FEATURES A CUTOFF UPPER LOW THAT HAS BEEN IN THE REGION FOR THE LAST SEVERAL DAYS.
347 PM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE SOUTH INTO THE AREA TODAY.
UPPER LOW SEEN SPINNING ON WATER VAPOR MOVIE LOOPS WELL TO OUR WEST OVER COLORADO. HOWEVER BETTER CHANCES STILL EXPECTED FURTHER EAST WITH IN VICINITY OF THE TROUGH AXIS. RH FIELDS NOTING LOW STRATUS TO BE IN PLACE ACROSS THE CWA THROUGH MUCH OF THE MORNING AND COULD START TO SEE SOME BREAKS IN THE STRATUS THIS AFTERNOON ACROSS THE WESTERN CWA WITH SOME SUBSIDENCE AND THE WARMER APRIL SUN HELPING TO ERODE IT AS WELL. OVERALL TEMPERATURES TO STILL REMAIN A LITTLE COOLER IN THE MID 60S TO AROUND 70 FOR HIGHS DUE TO THE LINGERING CLOUD COVER.
357 PM CDT TUE APR 19 2016 THE LARGE SCALE WEATHER PATTERN HAS A LARGE LOW PRESSURE CENTER OVER THE WRN US. THIS LOW HAS BEEN ROTATING VORTICITY MAXIMA INTO THE UPPER MIDWEST.
1222 PM CDT TUE APR 19 2016 Large closed low slowly drifting into the High Plains remains the main weather story for the next few days, as this system will continue to push several more rounds of rain into the region. For today, a weak cold front is becoming quasi-stationary near the southern and eastern borders of our forecast area, and this feature will be the primary focus for any rainfall through most of the afternoon. This will keep the higher precipitation chances focused across the Clinton/Sedalia areas and then up the US-63 corridor.
Weak cold front will sag south into the Big Country overnight, and there is some indication that a band of convection could precede the front and affect at least part of the Big Country. A weak cold front will also move into/dissipate over the region after midnight and may provide a low level boundary for additional development. Despite stronger instability in southern sections, most of the models do indicate a better chance of storms over northern sections, along and north of a Sterling City to San Angelo to San Saba line, in the presence of stronger upper divergence and weak surface cold front.
341 PM CDT TUE APR 19 2016 OLD PESKY UPPER LOW WILL CONTINUE TO SLOWLY SHEAR ACROSS THE CENTRAL PLAINS THROUGH THE NEXT COUPLE DAYS. FOR LATER WEDNESDAY ANOTHER BAND OF RAIN SETS UP MAINLY JUST SOUTH OF THE CWA AS A WAVE ROTATES AROUND THAT DEPARTING UPPER LOW.
A WEAK SYSTEM OFFSHORE OF SAN FRANCISCO WILL PUSH INLAND OVER THE NORTHERN COAST TONIGHT AND BRING A COOLER AIR MASS TO THE REGION.
PRECIPITATION CHANCES INCREASE FOR SECOND HALF OF THE WEEK WITH AN UPPER LEVEL LOW/COLD FRONT. HIGH PRESSURE FOR THE WEEKEND.
135 PM EDT TUE APR 19 2016 COLD FRONT LOCATED FROM NORTHEAST PA TO CENTRAL OHIO WILL CONTINUE TO MOVE SOUTHWARD THROUGH THE DAY. HIGH PRESSURE WILL BUILD INTO THE REGION INT HE WAKE OF THE FRONT. THE HIGH WILL TRACK DRIFT SOUTHEASTWARD ACROSS NY STATE ON WEDNESDAY. A WARM FRONT WILL LIFT NORTHEASTWARD ACROSS THE AREA WEDNESDAY NIGHT.
LOW PRESSURE WILL THEN APPROACH SOUTHERN WISCONSIN DURING THE DAY WEDNESDAY. TEMPS/DEWPOINTS WILL INCREASE AHEAD OF THE LOW. EXCEPT FOR COOLER TEMPS NEAR LAKE MICHIGAN UNDER ONSHORE WINDS.
300 PM CDT TUE APR 19 2016 THE SHORT TERM PERIODS WILL FEATURE CLOUDY CONDITIONS WITH PERIODS OF RAIN UNDER THE INFLUENCE OF AN UPPER CYCLONE WHICH ENCOMPASSES MUCH OF THE INTERIOR CONUS. THE CENTER OF THE UPPER LOW WAS LOCATED IN EAST CENTRAL COLORADO EARLY THIS AFTN WITH A LEAD WAVE LIFTING OUT OF THE SYSTEM ACROSS KS INTO NEB. TEMPS WILL BE MILDER WHERE DRIER CONDITIONS AND A FEW BREAKS IN CLOUD SHLD ALLOW READINGS TO REACH THE LOW/MID 60S. THE UPPER LEVEL LOW THAT HAS BEEN AFFECTING THE AREA FOR THE PAST FEW DAYS WILL BE EAST OF THE AREA WEDNESDAY NIGHT. MODELS HAVE SOME DIFFERENCES IN THE LOCATION OF THE UPPER LOW AND HOW MUCH PRECIPITATION MOVES IN FROM THE NORTH DURING THE NIGHT.
High pressure continues to dominate the weather over western Montana and central Idaho. It is an odd shaped ridge due to a cut off low pressure system over Wyoming and Colorado causing easterly flow over much of the region. Farther west, the ridge is stronger and has recently caused record high temperatures along the west coast, with temperatures today in these areas as much as 25 degrees above average. Over the next few days this strong ridge will move east, though it will be weaker due to a short wave moving through the ridge.
424 PM EDT TUE APR 19 2016 HIGH PRESSURE REMAINS ANCHORED ACROSS THE SOUTHEAST AND THE FLORIDA PENINSULA WITH PARTLY CLOUDY SKIES OBSERVED ACROSS THE REGION.
133 PM EDT TUE APR 19 2016 HYDRO COOLER AIR HAS MOVED INTO SOUTHWEST MICHIGAN AN WILL REMAIN OVER THE AREA INTO THE WEEKEND.
A TROPICAL MOISTURE TAP FROM THE PACIFIC CONTINUED STREAMING OVERHEAD A WEAK NORTH-TO-SOUTH SURFACE BOUNDARY THAT WAS LOCATED NEAR THE INTERSTATE 45 CORRIDOR AT 2 PM /SURFACE DEWPOINTS TO THE EAST OF THE BOUNDARY WERE IN THE LOWER 70S. THE HIGH RESOLUTION MODELS FORECAST THE ACTIVITY TO DIMINISH LATER TODAY BETWEEN MID EVENING AND MIDNIGHT.
445 PM EDT TUE APR 19 2016 UPPER RIDGE THAT HAS BEEN DOMINATING OUR WARM AND SUNNY WEATHER WILL FINALLY START TO BREAK DOWN THIS EVENING AS THE MAIN UPPER LEVEL LOW STARTS ITS SLOW PROGRESSION EASTWARD. THE BREAKDOWN OF THE RIDGE WILL ALLOW FOR MID AND HIGH LEVEL CLOUDS TO MOVE INTO THE AREA THIS EVENING AND OVERNIGHT. TEMPERATURES TOMORROW WILL BE SLIGHTLY COOLER BUT STILL APPROACH THE 80 DEGREE MARK.
247 PM EDT TUE APR 19 2016 HIGH PRESSURE IS MOVING INTO THE REGION WITH DRIER AND COOLER AIR TAKING OVER.
544 PM EDT TUE APR 19 2016 HIGH PRESSURE MOVES ACROSS THE REGION TONIGHT AND WEDNESDAY.
348 PM CDT TUE APR 19 2016 THE LARGE SCALE WEATHER PATTERN HAS A LARGE LOW PRESSURE CENTER OVER THE WRN US. THIS LOW HAS BEEN ROTATING VORTICITY MAXIMA INTO THE UPPER MIDWEST.
321 PM MDT TUE APR 19 2016 DRAWINGS ON THE H5 RAOB CHART INDICATE THE UPPER LOW CIRCULATION HAS FINALLY CROSSED THE GREAT DIVIDE. PATTERN REMAINS STALLED ACROSS THE LOWER 48 AND THIS LOW IS BASICALLY GOING TO MAKE LITTLE PROGRESS OVERNIGHT. CONDITIONS SHOULD BE CLEARING SUBSTANTIALLY AS HIGH PRESSURE BUILDS ACROSS THE SOUTHWEST.
150 PM PST Mon Mar 6 2017 High pressure will gradually build in from the west this week.
919 AM PST Mon Mar 6 2017 High pressure will gradually build in from the west this week.
There is a surface cold front sliding south in Montana tonight that may well boost the winds again around midnight.
This will help set the stage a severe weather late this afternoon and into tonight across much of eastern Oklahoma and western Arkansas as a cold front is slated to move through the area tonight. The majority of the thunderstorm activity is expected to take place in the vicinity of the cold front as it moves through the area after 02z. Isolated thunderstorms will be possible in advance of this cold front late this afternoon and evening.
The drying and clearing trend will persist into the evening ahead of deepening low pressure system over the northern plains with trailing cold front that stretched south and southwest through the Plains states into west Texas.
Around 1 to 2 inches of additional snow fall is expected across the highest mountain elevations by the end of the day. The cold front that moved south over North Central Montana yesterday will also retreat north to near a Cut Bank to Lewistown line today, which should help warm the plains back into the upper 20s to lower 30s as breezy west-northwest winds mix down to the surface. This pattern of mainly mountain snow, breezy westerly winds, cooler than normal temperatures, patchy blowing snow, and possible afternoon snow showers over the plains will continue through Tuesday, as lows mostly fall back into the teens overnight.
Water vapor loop indicate upper level low over the NE panhandle. Upper level trough will move over LS by morning. Upper level system with another upper low over southern SASK by morning.
1032 AM MST Mon Mar 6 2017 Snow wrapping around the west side of the upper low has been creating areas of difficult travel conditions over northeastern Wyoming this morning as the gusty northwest winds create areas of significantly reduced visibility in falling and blowing snow, and areas of slippery road conditions develop. 09z surface analysis had low near K2WX with prefrontal trough into southwest WY. Cold front developing from low into northwest WY. Water vapour loop had upper trough from southwest Canada into the southern Rockies. Cold front races through CWA this morning behind low. Winds will die down some tonight, but it is now looking like another potential high wind event Tuesday as a secondary wiggle drops into the Dakotas around stacked cyclone.
An upper trough moving through CO this afternoon will slowly shift eastward overnight tonight. Models are relatively consistent with the cold front entering our NW counties around or just after midnight. Front slows down a little during the day tomorrow as the upper trough lifts northward, so we may have some lingering rain in our SE counties through the early afternoon.
424 PM EST Mon Mar 6 2017 High pressure will cross the region tonight. A warm front will cross the region Tuesday.
143 PM EST Mon Mar 6 2017 High pressure will push off the east coast today. A cold front will sweep southeast across the region late Tuesday.
A cold Pacific trough will continue to cross the region today. Upper cold pool coincident with the trough encompassing much of the western CONUS resides over the northern third of the state attm. As the upper trough pulls east late today and tonight, will see a transition to low level warm advection overnight, which coupled with ample moisture will likely result in another round of snowfall for areas generally north of I-80, although increasing stability as the mid level cold pool shifts east and 500mb temps rapidly warm will likely limit snow totals.
131 PM EST Mon Mar 6 2017 Aviation A deepening low pressure system located in the Upper Plains will track into the Canadian Prairies tonight. Later tonight and Tuesday morning a cold front will track eastward through the area triggering showers and even a few thunderstorms.
907 AM MST Mon Mar 6 2017 Cooler has filtered into the region behind a cold front with slightly colder than average temperatures. A dry cold front is currently moving across our CWA and is associated with a broad upper level trough which is clearly seen on satellite IR and water vapor imagery. The best dynamics with this trough are well to our north in Utah which is currently seeing light showers in the area. This trough will continue to march eastward while surface pressure gradients continue to weaken. Cooler air has filtered into our region which will lead to high temperatures 5-7 degrees below normal. However, the cooler weather won't last for long. By Monday evening, models are in excellent agreement that H5 heights will begin rising as a result of a ridge building over our area.
Cooler air has filtered into the region behind a cold front with slightly colder than average temperatures. The dry cold front that moved across our CWA is associated with a broad upper level trough that will be delivering severe weather well to the east of our area in the Central Plains. Nearly clear skies are dominating the desert Southwest with just a few clouds sprinkled across the higher terrain north and east of Phoenix. Cooler air has filtered into our region behind the aforementioned cold front leading to high temperatures 5 degrees or so below normal. However, that changes tomorrow and throughout the week as temperatures in the lower deserts will flirt with, and in some cases, exceed 90 degrees. Both the GFS and ECMWF are indicating ridging over the southwest U.
Furt- her north, we will be seeing development along/just ahead of the cold front moving down from the Southern Plains. A brief break in the weather expected behind this front for most of Weds as a flat upper ridge builds in from the west. The next cold front is currently on track for a Sat night FROPA across SE TX. Expecting south southeast winds out ahead of the next cold front that is passing through SE Texas Tuesday afternoon.
341 PM EST Mon Mar 6 2017 High pressure will slide to the New England coast today and offshore tonight into mid-week allowing much milder air to stream into the region. Widespread rain showers will continue through the overnight hours as a cold front swings through the North Country Tuesday night. The warm air advection through the early evening hours should make sure that all locations see just convective rain through around midnight and then as the cold air advection starts to push into the north country we will see a transition from rain to a rain/snow mix in the higher terrain at elevations above 2500 feet.
Between 06z and 12z, expect scattered showers to develop over western parts of the Mid-State, as a cold front moves in from the west. Conditions are expected to remain VFR until late Monday night, when MVFR ceilings are expected to develop ahead of the approaching cold front.
Look for a mix of rain, snow and sleet in the lower valleys with the stronger showers producing dusting of sleet and snow. The West Central and Boise Mountains could see 3 to 6 inches of snow in the mountain valleys and up to a foot of snow in the higher peaks tonight through Tuesday. A significantly moist warm pattern will begin Tuesday with passage of a warm front.
Late morning temperatures have warmed into the low/mid 60s with southerly winds of 10-20 mph, and some higher gusts (especially in the higher more exposed terrain). Even with way more clouds than sun, kept high temperatures on the warmer side of guidance (upper 60s to around 70). A distinct warm conveyor belt will shift into the lower MS valley this evening, associated with the low level jet of 50-65kt. This will produce mostly light precipitation initially in advance of the cold front in MO, AR, and TX. The cold front will drop southeast and approach northwest AL before midday. This will be when the highest chance of thunderstorms will occur. Precipitation will exit quickly Tuesday evening as the cold front continues to progress to the southeast.
Temperatures will start the week just a bit cooler than normal then quickly warm through the week to much warmer than normal levels for the first half of March. Cooler day across the area with highs at or several degrees below normal. With cooler air mass in place, the lows Tuesday morning will be quite cold in the eastern valleys were the usual cold spots will see low temperatures in the 28-32 degree range.
314 PM EST Mon Mar 6 2017 High pressure will continue to shift off to the Northeast tonight and through the early part of this week.
Stronger winds will be expected post-dryline this afternoon across the western third or so of Oklahoma with the highest gusts across northwest parts of Oklahoma. As far as convection goes later today, models continue to support idea of convective develop during the evening and overnight period as cold front catches up with dryline and helps with lower level convergence. Winds should diminish around sunset but a cold front will move through during the evening bringing a switch in direction to northwesterly.
Strong and gusty southerly winds will continue through the afternoon between high pressure ridging across the southeast CONUS and strong low pressure set up through the plains. This low level south flow will continue to advect gulf moisture over the area sufficient to produce scattered showers through the afternoon as well as a few thunderstorms.
Stratus will move north into the area late this evening and early Tuesday morning, ahead of an approaching cold front. The cold front will approach the northern Big Country around midnight, central portions of the forecast area around 3 AM and then across the Interstate 10 corridor around 6 AM.
Winds should diminish around sunset but a cold front will move through during the evening bringing a switch in direction to northwesterly.
310 PM EST Mon Mar 6 2017 A warm front will approach tonight and Tuesday, bringing some light rain and some fog Tuesday and Tuesday night. The rain may start as a little light freezing rain and sleet across NH and interior western ME late tonight and Tuesday morning.
110 PM EST Mon Mar 6 2017 High pressure will slide to the New England coast today and offshore tonight into mid-week allowing much milder air to stream into the region. Cold front will push across our forecast area Tuesday night.
228 PM EST Mon Mar 6 2017 Cold front passes late Tuesday evening.
A low light shower chance will continue near the east coast as the low level flow veers overnight. Southeast low level flow around the Atlantic ridge will make for warmer day especially for the interior with highs near 80 to the lower 80s well inland and upper 70s near the east coast. Some drying in the mid levels will limit shower chances but will still keep a low shower chance near the east coast with a slight chance for some light showers working around the low level ridge axis. High pressure pulls farther east from the mid Atlantic coast with local winds veering toward the southeast and decreasing. Overnight mins range from upper 50s cooler interior to lower 60s rest of the area.
Temperatures will start the week just a bit cooler than normal then quickly warm through the week to much warmer than normal levels for the first half of March. Pleasant cooler than normal March day across southeast Arizona. With cooler air mass in place, the lows Tuesday morning will be quite cold in the eastern valleys were the usual cold spots will see low temperatures in the 28-32 degree range.
1247 PM EST Mon Mar 6 2017 An approaching cold front will cause strong southerly winds, unseasonably warm temperatures, and showers especially over southeast portions of the area this afternoon and early tonight. A few more days of warmer weather will be in store for the region, but at a cost. Focus shifts to cold front which will sweep through late tonight into Tuesday. Pops will subsequently increase as the front approaches but some concern how much shower activity will occur well ahead of the main front and associated upper level trough.
309 PM EST Mon Mar 6 2017 High pressure centered just east of the Atlantic coastline near the Delmarva Peninsula is moving east, conceding real estate to the cyclone moving northeast through the Central Plains.
