342 PM CDT SAT JUL 18 2015 BROAD UPPER LEVEL RIDGE REMAINS ANCHORED ACROSS THE SOUTHERN PLAINS AND SOUTHEASTERN CONUS. A TROUGH IS PUSHING ACROSS SOUTH CENTRAL CANADA. WITH A SUBTLE TROUGH OVER THE PACIFIC NORTHWEST. THIS WILL CONTINUE TO ROTATE AROUND THE RIDGE INTO SW NEB THIS EVENING AND OVERNIGHT. IN THE MID TERM SOLUTIONS MODELS IN FAIRLY GOOD AGREEMENT WITH FLATTENED SOUTHERN PLAINS RIDGE AND CUTOFF LOW OFF THE CALIFORNIA COAST. ENERGY CONTINUES TO BE EJECTED OUT OF THE TROUGH TO THE WEST.
MEANWHILE, AN UPPER LEVEL JET STREAMING NORTHEAST OUT OF THE TROUGH AXIS ACROSS THE GREAT BASIN WILL INTENSIFY OFF TO OUR NORTHWEST AS IT LIFTS INTO THE NORTHERN PLAINS. ALTHOUGH THE BULK OF THE FAVORABLE SUPPORT ALOFT WILL REMAIN OFF TO THE NORTH, ENOUGH INSTABILITY WILL REMAIN PRESENT WITH MUCAPE VALUES UPWARD OF 3000 J/KG TO SUPPORT THUNDERSTORM DEVELOPMENT IN THE VICINITY OF THE COLD FRONT AS IT SLOWLY MOVES SOUTHWARD INTO WESTERN KANSAS. BASED ON THE HIGH CAPE VALUES AND FAIRLY FAVORABLE VERTICAL SHEAR PROFILES, THE POTENTIAL FOR STORMS BECOMING SEVERE WILL BE HEIGHTENED. TEMPERATURES WILL BE HOT ONCE AGAIN TODAY AS A PREVAILING SOUTHERLY FLOW REINFORCES THE MUCH WARMER AIR MASS IN PLACE ACROSS CENTRAL AND SOUTHWEST KANSAS. LOWS ARE EXPECTED DOWN INTO THE 60S(F) ACROSS WEST CENTRAL KANSAS TO THE LOWER 70S(F) IN SOUTH CENTRAL KANSAS TONIGHT.

641 PM EDT SAT JUL 18 2015 A COLD FRONT WILL MOVE ACROSS THE REGION ON SUNDAY.
WEAK HIGH PRESSURE WILL BUILD INTO THE REGION LATE TONIGHT AND WILL CAUSE PARTLY TO MOSTLY SUNNY SKIES ON SUNDAY WITH LESS HUMID CONDITIONS. A COLD FRONT WILL MOVE INTO NORTHERN MINNESOTA SUNDAY EVENING.
231 PM EDT SAT JUL 18 2015 A SURFACE PRESSURE TROUGH WILL BE IN THE FORECAST AREA THROUGH SUNDAY. HIGH PRESSURE WILL EXTEND INTO THE AREA FROM THE SOUTHERN PLAINS. A LEE-SIDE TROUGH IN THE FORECAST AREA WILL CONTINUE THROUGH SUNDAY NIGHT. STRONG HEATING WITH CONVERGENCE INTO THIS FEATURE MAY SUPPORT THUNDERSTORMS BUT UPPER RIDGING EXTENDING INTO THE AREA FROM THE WEST SHOULD LIMIT COVERAGE.
WARM FRONT WELL TO THE NORTH OVER MN AND WI PUTS THE CWFA SOLIDLY IN THE WARM SECTOR WITH DEW POINTS AND TEMPERATURES HOLDING IN THE UPPER 70S THIS MORNING. ZONAL FLOW ALOFT WITH A STRONG WAVE AND ASSOCIATED COLD FRONT CROSSING THE DAKOTAS. GREATEST RISK FOR SEVERE STORMS WILL BE THIS AFTERNOON AND EARLY EVENING AS THE COLD FRONT APPROACHES. GIVEN THE LOW-LEVEL INSTABILITY ALREADY IN PLACE. A COOLER DAY IS EXPECTED SUNDAY. AS THE COLD FRONT ENHANCED BY CONVECTIVE OUTFLOW.
THE CONSENSUS OF THE 00Z MODEL CYCLE IS THAT THE UPPER-LEVEL RIDGE WILL HOLD STRONG ACROSS THE REGION THROUGH THE WEEKEND.
AS EVIDENCED BY A FEW SHRA FORMING AND QUICKLY COLLAPSING IN THE NORTHEAST RIDGES. IT WILL BE ANOTHER MUGGY NIGHT WITH LOW TEMPS IN THE LOWER 70S FOR MANY. MORE FAVORABLE CONDITIONS FOR CONVECTION WILL BE SEEN SUNDAY AS MOISTURE GETS SWEPT INTO THE CWA AHEAD OF THE NEXT COLD FRONT. ANY STORMS THAT FIRE WILL BE MORE THEN CAPABLE OF PRODUCING HEAVY DOWNPOURS DUE TO THE HIGH SURFACE DEWPOINTS AND PWATS OF 1. PRECIP PROBABILITIES WILL INCREASE WITH THE APPROACH OF A COLD FRONT ON SUNDAY NIGHT.
657 PM CDT Mon May 2 2022 For the 00Z TAFs, gusty north winds in the wake of the latest cold frontal passage will continue at the terminal sites until mid to late this evening, diminishing thereafter and becoming southeast by Tuesday afternoon. The main cold front is still located in east central Colorado and west central Kansas with some cold air in its wake; with snow reported this morning in portions of northern Colorado and southern Wyoming. Although no snow in our forecast, the main cold front will move south through the OK Panhandle around sunset and the Texas Panhandle just before midnight. Behind the passing cold front, decent CAA will fill into the Panhandles. High temperatures tomorrow compared to today will be a bit cooler, but near average for early May with highs in the 70s with mostly clear skies.
The passage of a cold front tonight will usher in cooler temperatures Tuesday. North breezes will be strongest in the lower Colorado River Valley, while the rest of the region gets a break from the wind as high pressure builds in.
Strong winds are also forecast for portions of southeast Baker County and surrounding area, with gusts to 50 mph possible in the higher terrain as cool air is drawn south and east into a departing low pressure system. Surface winds: W-NW 15-25 kt with gusts 35-45 kt in the Magic Valley and the Lower Snake River Plain, elsewhere W-NW 5-15 kt with wind gusts 20-30 kt.
The axis of the surface Atlantic ridge is forecast to drop into North FL tomorrow, though still maintaining an ESE wind regime across Central FL.
937 PM EDT Mon May 2 2022 High pressure will remain off the Southeast coast for the next few days temperatures remaining above normal.
A warm front will continue to lift northward tonight, with a few upper level impulses coming into play within the warmer sector. a cold front will approach late in the day, so afternoon convection will again be possible.
Warmer temperatures and slightly drier air aloft decreased convective instability with result being less areal coverage of afternoon showers and thunderstorms.
606 PM CDT Mon May 2 2022 A rainy night is on tap for central Illinois, as low pressure arrives in central Illinois by late Tuesday morning.
842 PM EDT Mon May 2 2022 A summer-like air mass and upper-level ridging will dominate the weather during the work week.
Cooler Tuesday as well with highs in the 50s to mid 60s with some 40s for northern Elko county expected.
256 PM PDT Mon May 2 2022 Widespread gusty winds will prevail into this evening before winds subside and shift northerly behind a passing cold front.
702 PM EDT Mon May 2 2022 Seasonable temperatures are expected over the course of the week; thunderstorm chances increase tomorrow with crossing low pressure. Dry conditions and seasonable temperatures will continue the overnight as high pressure builds over the region. Moisture and warm advection will ramp up early Tuesday ahead of low pressure approaching from the west. Showers and elevated storms should develop by late morning/early afternoon with a warm front. for storms ahead and/or along the cold front.
/issued 241 PM CDT Mon May 2 2022/ Dry and warm gusty west winds were occurring across the area early this afternoon as a well-formed upper level low pressure system was steering east through the central plains. A cold front will soon follow, however, pushing south out of the Panhandle early this evening and crossing most of the Texas South Plains Region by midnight. Much cooler air will spread in by daybreak Tuesday, and low temperatures appear cold enough to require a Frost Advisory early Tuesday morning across the extreme southwest Texas Panhandle and northwestern South Plains. Northeast breezes Tuesday morning will quickly turn southeast in advance of yet another potent upper low crossing the Great Basin.
High pressure centered over the Western Atlantic will cause moderate to occasionally fresh breezes through Tuesday.
951 PM CDT Mon May 2 2022 As of 9:45 PM CDT, the warm frontal boundary remains to the north of our county warning area along the Ouachita Mountains, with a line of severe thunderstorms over southern and central Oklahoma that will continue southward overnight.
Mosaic 88D was showing precip activity was gradually exiting eastward with migration of associated upper level low. Meanwhile, a closed low was situated over the central Great Basin. At the surface, strong low pressure was situated over western MO with cool high pressure building in from the north. An upper ridge build in from the west today will aid with dry but cool conditions over the region.
Despite the low cloud cover guidance is producing low temperatures ranging from the middle to upper 20s in far eastern Colorado to the upper 20s to lower 30s along and east of the CO/KS border. our attention turns to another closed upper level low which is expected to reach northeast Utah by the end of the day, then over the Colorado/Wyoming Continental Divide area overnight.
500 AM EDT Tue May 3 2022 A low level ridge remains situated across across the western Atlantic and continues to maintain an east to southeast wind across the Florida Keys. Thus far, the Lower Keys have remained mainly dry. Dew points in the lower 70s are keeping conditions quite muggy. Prior to this occurring as the ridge slides east, our steering flow just above the boundary layer will shift from the south.
Will make a few tweaks to the low PoPs and remove thunder overnight. Otherwise, scattered convection will likely be approaching the TN valley after 00z ahead of an incoming cold front. CD Chattanooga Airport, TN 86 65 84 61 87 / 20 40 50 10 30 Knoxville McGhee Tyson Airport, TN 86 64 80 58 85 / 20 50 40 0 40 Oak Ridge, TN 86 62 80 57 84 / 20 60 40 10 40 Tri Cities Airport, TN 84 62 77 55 82 / 50 60 50 0 30.
As the low exits Ohio to the northeast, a cold front will cross the region and any showers lingering over the south will come to a quick end this evening.
335 AM EDT Tue May 3 2022 Overall pattern across the region has a weak trough moving through the region with a closed low over Nebraska that's tracking slowly east-northeast. The weak trough, aided by light upslope flow and ample low level moisture, has supported some light drizzle/rain across the region. Additionally, with the low strata deck across the UP, temps have largely bottomed out in the high 30s away from the lakeshores and near 40 by the water. Medium range deterministic models are in agreement with a low pressure system quickly tracking through the Lower Midwest today and the trailing upper low over southern Wisconsin by this afternoon. But, forecast soundings indicate much drier air in the lower levels already by this afternoon as subsidence overspreads the area in a switch to an Omega block pattern.
235 AM MDT Tue May 3 2022 Current surface map places high pressure into the central Dakotas with low over the central Rockies. Compact upper low tracks across the central Rockies today then into the plains tonight.
This will allow for the east coast sea breeze to develop and push westward during the afternoon with the highest coverage over the interior and southwest Florida.
Progressive pattern will have an upper ridge with cool high pressure at the surface move across the region today.
The aforementioned high pressure will dominate the weather over the forecast area with mostly clear to partly cloudy skies, normal temperatures for this time of the year (upper 50s to low 60s) and dry weather.
308 AM CDT Tue May 3 2022 06z data has the main low in western Missouri with a warm front running east across southern Illinois. Tonight quiet, dry but chilly conditions will be seen as high pressure quickly moves into the Midwest and clouds break up.
/Issued 657 PM CDT Mon May 2 2022/ For the 00Z TAFs, gusty north winds in the wake of the latest cold frontal passage will continue at the terminal sites until mid to late this evening, diminishing thereafter and becoming southeast by Tuesday afternoon. The main cold front is still located in east central Colorado and west central Kansas with some cold air in its wake; with snow reported this morning in portions of northern Colorado and southern Wyoming. Although no snow in our forecast, the main cold front will move south through the OK Panhandle around sunset and the Texas Panhandle just before midnight. Behind the passing cold front, decent CAA will fill into the Panhandles. High temperatures tomorrow compared to today will be a bit cooler, but near average for early May with highs in the 70s with mostly clear skies.
This activity was along and east of a cold front that will approach our CWA tomorrow. Otherwise, another warmer than normal night is expected.
454 AM EDT Tue May 3 2022 Severe thunderstorms are expected to develop later today as a low pressure system tracks through the Ohio River Valley. With prevailing easterly flow in the boundary layer, due to high pressure over New England, a flux of low-level moisture will likely be delayed until the passage of the warm front early this afternoon.
