901 PM EDT WED MAY 4 2016 A SIGNIFICANTLY DRIER AIRMASS OVER SE GA CONTINUE TO EVER SO SLOWLY PUSH SOUTH INTO NORTHERN FLORIDA BUT THE COLD FRONT STILL RESIDES OVER OUR SOUTHERN ZONES WHERE DEWPOINTS REMAIN IN THE UPPER 60S. GIVING THE COLD FRONT A GOOD SHOVE TO OUR SOUTH ONCE AND FOR ALL WITH MUCH COOLER AND NOTICEABLY DRIER AIR ADVECTING SOUTH ACROSS OUR ENTIRE REGION OVERNIGHT. THE COLD AIR ADVECTION WILL ULTIMATELY RESULT IN TEMPS FALLING INTO THE LOW TO MID 50S OVER INLAND AREAS LATE TONIGHT/EARLY IN THE MORNING. THE WINDS WILL MAKE IT FEEL EVEN COOLER. COLD FRONT WILL FINALLY PUSH SOUTH OF THE WATERS BY AROUND MIDNIGHT.
LOW FREEZING LEVELS AND SOME APPRECIABLE INSTABILITY HAS HELPED TO PRODUCE INSTANCES OF SMALL HAIL AND SOME MINOR WIND DMG ACROSS THE AREA. THE UPPER LOW IS CURRENTLY LOCATED OVER IN AND IS MOVING SOUTH SOUTHEASTWARD.
1056 PM EDT WED MAY 4 2016 AFTER A WEAK DISTURBANCE BRINGS SCATTERED SHOWERS TO THE REGION THIS EVENING, THE TREND WILL BE TOWARDS DRIER AND WARMER CONDITIONS THROUGH THE END OF THE WEEK AS DEEP UPPER LEVEL LOW PRESSURE DROPS SOUTH OF THE NORTH COUNTRY.
1052 PM EDT WED MAY 4 2016 CHANGES TO FORECAST -- ADJUSTMENTS HAVE BEEN MADE TO ALL ELEMENTS FOR THE OVERNIGHT TRANSITION/TROUGH PASSAGE. A NEW BAND OF LESS INTENSE SHOWERS AND ISOLATED STORMS HAS DEVELOPED AHEAD OF THE TROUGH/WIND SHIFT LINE OVER THE SOUTHEASTERN GULF OF MEXICO. AND DEWPOINT TEMPERATURES ARE STILL IN THE LOWER 70S. WINDS WILL SHIFT NORTHWEST AND DIMINISH SOME OVERNIGHT AS A TROUGH MOVES THROUGH THE FLORIDA KEYS AND ADJACENT COASTAL WATERS. A COLD FRONT WILL SWEEP THROUGH THE AREA BY EARLY THURSDAY. A HIGH PRESSURE AREA WILL MIGRATE EASTWARD.
724 PM EDT WED MAY 4 2016 COLD FRONT CONTINUES DEPARTING THE REGION ALLOWING A COOLER AND DRIER AIRMASS TO OVERSPREAD THE AREA.
1130 PM CDT WED MAY 4 2016 Deep upper-level ridge over the Rockies will be the dominant weather feature for the next 2-3 days as it gradually shifts eastward into the Plains.
1233 AM EDT THU MAY 5 2016 LOW PRESSURE OVER SOUTHEAST MICHIGAN WILL MOVE SOUTHEAST ACROSS THE AREA THIS EVENING AND THEN GRADUALLY BECOME ABSORBED IN A LOW PRESSURE SYSTEM ALONG THE EAST COAST TONIGHT AND THURSDAY.
/ISSUED 341 PM CDT WED MAY 4 2016/ AN OMEGA BLOCKING PATTERN WILL PREVAIL OVER CONTIGUOUS U.
The cold air mass associated with the upper low will provide for below normal temperatures in the low 40s across central IL. Upper level low center seen in IR imagery over southwest MI will drop slowly to the south overnight, with weak upper wave rotating around it. The closed 500 mb upper low will be located over northern Kentucky by tomorrow morning with our area still under some decent low and mid level cyclonic flow, at least through early afternoon.
GENERALLY CLOUDY CONDITIONS PERSIST AS MOISTURE STREAMS NWD AHEAD OF UPPER LOW DROPPING INTO THE SRN GREAT LAKES REGION. THE UPPER LOW LOOKS TO ENSURE UNSETTLED AND SHOWERY CONDITIONS THROUGH THE END OF THE WEEK. THE MODELS CONTINUE TO SHOW THE GREATEST PCPN RISK FOCUSED ALONG INVERTED TROUGH/DEFORMATION AXIS PIVOTING NWD INTO CENTRAL PA. LARGE TROUGH WITH CLOSED H5 LOW REACHING ITS FURTHEST SOUTHERN EXTEND THU NIGHT OVER NC WILL THEN LIFT BACK INTO THE COASTAL MID ATLANTIC REGION FRI INTO SAT.
(Tonight and Thursday) A deep trough continues to move slowly east across the Great Lakes this afternoon, with another deep cyclone inching slowly toward the CA coast. A sharp upper-level ridge has built between these troughs, extending from the Southern Rockies, north into the Prairie Provinces. Dry northwesterly flow aloft downstream of this ridge will continue over the Southern Plains through the next 24 hours, maintaining mostly clear skies and tranquil weather conditions across West Central TX. With dewpoints in the 40s and clear skies overhead, temperatures should have no problem falling into the lower 50s across much of the area overnight.
759 PM EDT WED MAY 4 2016 AFTER A WEAK DISTURBANCE BRINGS SCATTERED SHOWERS TO THE REGION THE REST OF THIS AFTERNOON AND EVENING, THE TREND WILL BE TOWARDS DRIER AND WARMER CONDITIONS THROUGH THE END OF THE WORK WEEK AS DEEP UPPER LEVEL LOW PRESSURE DROPS SOUTH OF THE NORTH COUNTRY.
Latest surface analysis showed the broad area of high pressure from the Rockies into the the Central Plains. Pressure gradient will gradually weaken this evening as the high pressure moves slowly eastward. Lows temps tonight will fall into the lower 40s.
NORTHWESTERLY WINDS BEHIND THE BOUNDARY ARE STARTING TO USHER IN THE COOLER DRIER AIR. BY 06Z MOST OF THE LOW CEILINGS SHOULD HAVE MOVED OUT OF THE REGION WITH VFR CONDITIONS EXPECTED TO PREVAIL THROUGH THURSDAY.
UPPER LEVEL LOW CONTINUES TO CHURN OFF OF THE CENTRAL CALIFORNIA COAST.
with north winds dropping off as a ridge of high pressure builds into the area.
804 PM EDT WED MAY 4 2016 AFTER A WEAK DISTURBANCE BRINGS SCATTERED SHOWERS TO THE REGION THIS EVENING, THE TREND WILL BE TOWARDS DRIER AND WARMER CONDITIONS THROUGH THE END OF THE WEEK AS DEEP UPPER LEVEL LOW PRESSURE DROPS SOUTH OF THE NORTH COUNTRY.
1055 PM MDT WED MAY 4 2016 THE AXIS OF A RIDGE OF HIGH PRESSURE HAS MOVED OVERHEAD TODAY FOR WARM TEMPERATURES AND SUNNY SKIES. A FEW FLAT CUMULUS HAVE BEGUN TO DEVELOP OVER THE HIGHER TERRAIN THIS AFTERNOON. THE RIDGE WILL BEGIN TO SHIFT EAST AS THE NEXT PACIFIC LOW PRESSURE SYSTEM DROPS SOUTHWARD ALONG THE CA COAST. OVERNIGHT LOWS WILL BE WARMER THAN TONIGHT'S DUE TO THE WARM DAYTIME HIGHS. THE CHANCE FOR SHOWERS AND LATE DAY THUNDERSTORMS WILL INCREASE DURING THE WEEKEND AS THE LOW PRESSURE SYSTEM APPROACHES AND THEN PASSES OVER THE AREA.
WHERE HIGHS TODAY WERE WARMER AND THE SLIGHT DOWNSLOPE WIND TRAJECTORY THAT AIDED TEMPERATURES TODAY MAY ALSO HOLD THEM UP TONIGHT. AN UPPER LEVEL RIDGE WILL BE CENTERED OVER NORTH DAKOTA THURSDAY.
SPARKED FROM AN APPROACHING SHORT WAVE TROUGH. HOWEVER LIGHTNING IS SHOWING UP WITH SOME OF THE STORMS FURTHER WEST NEAR AND ALONG THE APPROACHING COLD FRONT. THE COLD FRONT WILL MOVE MOVE ACROSS THE AREA TONIGHT WHILE THE UPPER LOW MOVES SOUTHEAST FROM LAKE MI INTO KY. THERE IS GOOD MODEL AGREEMENT WITH THE UPPER LOW MOVING SE OF KY ON THURSDAY. WITH THE COLD MID AND UPPER LEVEL TEMPERATURES ASSOCIATED WITH THE UPPER LOW MORE SHOWERS WILL BE POSSIBLE ON THURSDAY INTO THURSDAY NIGHT.
VERY MILD CONDITIONS AS HIGH PRESSURE MOVES SOUTHEAST THROUGH THE AREA. THE LOW LEVEL THERMAL FIELD WILL BE ON THE RISE AS WELL SUPPORTING MUCH WARMER HIGHS.
718 PM EDT WED MAY 4 2016 LOW PRESSURE OVER SOUTHEAST MICHIGAN WILL MOVE SOUTHEAST ACROSS THE AREA THIS EVENING AND THEN GRADUALLY BECOME ABSORBED IN A LOW PRESSURE SYSTEM ALONG THE EAST COAST TONIGHT AND THURSDAY.
623 PM CDT WED MAY 4 2016 Deep upper-level ridge over the Rockies will be the dominant weather feature for the next 2-3 days as it gradually shifts eastward into the Plains.
625 PM CDT WED MAY 4 2016 FORECAST CONCERNS IN THE SHORT TERM ARE MINIMAL AS AN UPPER LEVEL RIDGE OF HIGH PRESSURE BUILDS EAST ACROSS THE HIGH PLAINS. WITH HIGHS TAPPING INTO THE LOWER 80S FOR MOST LOCATIONS ON THURSDAY.
UPPER TROUGH SHARPENING OVER THE MID WEST THIS AFTERNOON WITH RATHER VIGOROUS SHORT WAVE WORKING DOWN BACKSIDE AND WILL MOVE THROUGH MIDDLE TENNESSEE DURING THE AFTERNOON AND DEVELOP A CLOSED LOW ACROSS OUR AREA BY TONIGHT. CLOSED LOW WILL MOVE EAST OF MID STATE ON THURSDAY BUT STILL COULD SEE SCATTERED SHOWERS ON BACKSIDE OVER THE EAST HALF OF THE MID STATE DURING THE DAY ESPECIALLY ALONG THE PLATEAU.
TEMPERATURES ARE SLIGHTLY WARMER AT UPDATE TIME THAN ANTICIPATED.
AN UPPER LEVEL TROUGH ACROSS THE EASTERN HALF OF THE CONUS WILL BE THE PRIMARY WEATHER FEATURE THROUGH AT LEAST THE END OF THE WORK WEEK. MEDIUM/LONG RANGE MODELS DEPICT A FLAT RIDGE BECOMING ESTABLISHED ACROSS THE SOUTHEAST STATES BY THE END OF THE WEEKEND. IT APPEARS THAT AN UPPER LEVEL LOW EJECTING OUT OF THE SOUTHWESTERN STATES WILL START TO PROVIDE SOME LIFT TO BRING US OUR NEXT CHANCES OF RAIN/THUNDERSTORMS.
540 PM MDT WED MAY 4 2016 QUIET WEATHER ACROSS THE CWA THIS AFTERNOON WILL CONTINUE THROUGH THURSDAY AS AN UPPER RIDGE DRIFTS VERY SLOWLY EAST ACROSS THE AREA. GENERALLY CLEAR SKIES ACROSS THE REGION TONIGHT AND THURSDAY THEN A FEW SHOWERS MAY POP UP OVER THE HIGHER MOUNTAINS THURSDAY AFTERNOON AS MOISTURE BEGINS TO INCREASE A BIT THERE DURING THE DAY.
A low pressure system across east central Arizona will bring a slight chance of showers mainly east of Safford to Douglas line today into this evening. This system will still bring strong gusty winds today along with cooler temperatures.
1005 AM EDT Tue Mar 28 2017 A series of troughs moving through the area today will trigger some showers and possibly a few thunderstorms. A cold front will move through the area tonight.
Low clouds blanketed the CWA this morning, and with this advancing low pressure, expect little to no scattering of this cloud cover today. With this mid-level flow in place, the southerly flow ahead of the low across the Southern Plains will support increased moisture advection northward into the area. Upper low will be moving out of the Rockies early Wednesday and into the Southern Plains. Lobes of energy will rotate northward ahead of the main upper low across eastern Kansas.
The low level east to southeast flow will shift to onshore with the bay/sea breezes this afternoon and with limited moisture mostly below about 800 mb we will not see much more than some scattered to broken stratocumulus/altocumulus this afternoon and evening. Temperatures will warm into the lower to mid 80s, except near the coast where the sea breeze should hold readings in the mid to upper 70s. However, did tweak high temperatures up a degree or two as the mid/upper level ridge will be building over us and we should see high temperatures similar to yesterday if not a little warmer away from the coast.
Otherwise, weakening high pressure ridge settling over central Florida will produce light winds and the dry air mass will result in mostly sunny skies. High temps will reach the lower 80s along the coast and mid 80s inland. High pressure ridge over the area will provide VFR through tonight. Good boating conditions with light/variable winds due to weak high pressure over the area.
Not much change for Wed except that upper ridge gets even a little stronger in response to digging trough well to the west. This will allow for temps just about areawide to reach the low to mid 80s. Ridge should also preclude any significant precip development but will keep a sliver of 20 pops across Central GA for now where moisture and instability is enhanced.
1050 AM EDT Tue Mar 28 2017 A cold front will cross the area tonight.
High pressure aloft will expand across the Great Basin tonight through Wednesday. The axis of the upper trough along the Utah/Colorado border will continue east today. A increasingly dry/stable air mass will follow the exiting trough as the upper ridge currently along the west coast expands east across the Great Basin tonight through Wednesday.
A weaker upper level trough dips into the region through the weekend potentially generating some showers across northern SD.
/Issued 405 AM CDT Tue Mar 28 2017/ A quiet overnight period with high pressure over the region.
07z sfc analysis shows a low pressure moving through the Ohio Valley. Now the bulk of these initial showers and storms have moved off to the east while a few lighter ones trail back toward the system's cold front now pressing through western Kentucky. They all depict a trough passing through Kentucky this morning as it moves off to the East Coast by evening. This will be followed by rising heights and broad ridging through the mid part of the country tonight into Wednesday. Meanwhile, the next in a series of deep troughs will be moving through the Four Corners region.
Couple of troughs extended from lows into southeast MT and south central SD. Water vapour has upper low spinning over central AZ, which is a bit further south than previous guidance showed. Northern branch of upper trough moving across MT. Today and tonight, upper low moves into the TX panhandle by 12z Wednesday which is a bit slower and further south than previous guidance. Inverted trough feature extending north into the CWA will be focus for precipitation today and tonight given modest synoptic scale lift and low level frontogenesis. Boundary layer temperature forecast shows wet bulbs 1-2C warmer than yesterday and thus, snowfall looks to be limited to the very highest elevations.
731 AM EDT Tue Mar 28 2017 Aviation One area of low pressure will track up the Ohio Valley today. An area of high pressure in the upper plains will track east tonight and Wednesday scattering the clouds out.
Fairly deep saturation is expected on Wednesday as deep trough churns across the central plains.
As the cyclone wraps up over west Texas, several rounds of thunderstorms are expected across Oklahoma and north Texas. Elevated warm-air advection in advance of the trough will likely set off a few showers and thunderstorms this morning over western Oklahoma and adjacent parts of Texas.
Seems like it may stick a bit longer than anticipated, and this would also impact temperatures this afternoon -- keeping things a bit cooler than originally forecast.

Low stratus was in place over the Ozarks this morning as an upper level ridge moves over the Ozarks. The ridge will bring a dry day to the area with temperatures rising into the middle 60s for most of the region with near 70 degrees in extreme southwestern parts of the area. Despite the ridge over the area, cloud cover will be stubborn with only a few peeks of sun expected. The ridge will begin to shift east this evening and overnight as a strong storms system moves out of the four corners region and takes a similar track as this past weekends system.
702 AM CDT Tue Mar 28 2017 As the low pressure area that brought rain to the CWA yesterday moves off to the east, a brief period of dry weather is expected as a high pressure ridge slides across the area today through tonight. Temperatures through the period will average a little warmer than normal, with the warmest readings expected ahead of each system to impact the area. Quiet conditions will persist into early Wednesday as upper/surface ridging slowly drift east of the area. Then, increasing WAA/isentropic ascent ahead of a slow moving upper low/trof (currently pushing into the Four Corners region) will return the threat of showers to the area.
Upper level ridging will maintain dry weather today through tonight.
619 AM CDT Tue Mar 28 2017 A brief return of mid-level ridging over the Central Plains will maintain dry conditions despite persistent low level moisture beneath 850 hPa. Values will range from the mid 50s north of the I-70 corridor to the lower 60s for points south, where weak WAA will persist.
956 AM CDT Tue Mar 28 2017 Surface analysis this morning shows a weak cold front pushing into far NW AL at the moment.
Latest model runs bring the southwest trough into the southern Rockies by tonight with strong moisture advection moving into eastern Kansas in advance of the system.
VAD wind profile from the KHGX 88D only shows 15-25 knots in the lowest levels, but those winds should increase during the day.
A strong upper level low is currently digging southeast into southeastern AZ. This low and associated upper level lift will move into central New Mexico today, then nearly stall overnight near the Texas/New Mexico border in northeastern New Mexico. At the surface, we are already seeing changing conditions as pressure falls ahead of the upper low increase south to southeasterly flow and moisture across our area. Moisture and instability will continue to increase through the afternoon hours today as the upper low approaches. Moving into the evening/overnight hours, as the low moves into northeastern NM, the main upper level energy will move across our region. A Pacific cold front will move into the area during the evening hours, which is expected to trigger a line of thunderstorms developing near our western border, then moving east across our CWA during the overnight hours.
759 AM EDT Tue Mar 28 2017 High pressure over the region will keep VFR in the forecast for all TAF sites through the TAF period.
Another warm and muggy night tonight with winds remaining elevated, especially along the coast and over the WRN zones as a 30-40KT LLJ begins to overspread the area with the approach of the upstream trof. This is expected to begin changing by afternoon, however, as more favorable lapse rates begin to overspread the area along with falling heights and a split jet structure as the upper trof enters the TX panhandle. Dry weather is expected in the wake of the frontal passage FRI and SAT, with rain chances returning SAT night with the approach of another upper level trof.
Global models are showing an upper ridge pattern quickly building over the SE region on Wed, and then translating ewd Wed night into Thu. The ridge axis should help overall temps remain unseasonably warm, with highs reaching the upper 70s/lower 80s Wed afternoon, while overnight lows trend well into the 50s both tonight and again Wed night.
Surface winds shift to northeast or east as boundary pushes south as a cold front. The upper low which will bring this moisture is moving across western New Mexico this morning. This low will help to spark showers across the western portions of the Panhandles as early as 6 AM. These storms are anticipated to move northeastward across the Panhandles as the upper low moves closer to the Panhandles over the course of the day. recent model runs have shown the track of the upper low to be slightly further south than previously indicated. This, as well as morning convection, will help to keep the warm front further south that previous thought.
Drier air will continue to work into the area today as high pressure centered north across Manitoba/Ontario noses southeastward into the Upper Midwest. The main question today will be how quickly the low stratus/fog persists. However, by tonight mid and high clouds will be on the increase ahead of another southern stream upper low coming out of the Desert Southwest. As low-level warm advection increases, gradual moistening of the low-levels should occur, with showers increasing, especially west of the Mississippi during the day.
A low pressure center will shift east into New Mexico by this afternoon with decreasing shower and thunderstorm activity.
A ridge of high pressure will build into our region and provide warmer weather the next couple of days.
The low clouds run from Grove to Tulsa to Chandler, as well as some stratus down near Hugo. Upper low is now into southern New Mexico with widespread elevated storms ongoing across the TX panhandle and western Oklahoma. Surface warm front extends from near Lubbock east across north central Texas this morning and will lift north to the Red River by late afternoon.
/issued 404 AM CDT Tue Mar 28 2017/ Dense fog developed quickly early this morning across Northeast Arkansas, the Missouri Bootheel, and West Tennessee as some clearing took place behind the cold front. The cold front will stall out this morning over Central Mississippi. The front will begin lifting back northward as a warm front tonight. On Wednesday, winds will turn around to the south behind the warm front. As the storms push into Eastern Arkansas Wednesday evening, the low-level jet is expected to strengthen helping maintain strength of the storms.
Winds will increase throughout the day as the low that is expected to bring showers and thunderstorms tomorrow deepens and pushes east out of western Texas. Another warm and muggy night tonight with winds remaining elevated, especially along the coast and over the WRN zones as a 30-40KT LLJ begins to overspread the area with the approach of the upstream trof. This is expected to begin changing by afternoon, however, as more favorable lapse rates begin to overspread the area along with falling heights and a split jet structure as the upper trof enters the TX panhandle. Dry weather is expected in the wake of the frontal passage FRI and SAT, with rain chances returning SAT night with the approach of another upper level trof.
After holding in place to keep today cool, the low clouds should clear from the northeast this evening, and before the mid level moisture spreads back over all areas overnight, it does look like radiational cooling will be a factor northeast, where lows in the mid 30s are forecast, otherwise upper 30s to lower 40s should be found over the remainder of the CWA.
948 AM EDT Tue Mar 28 2017 Low level ridge axis has shifted south of the region and extends from the GOMEX across the FL peninsula and this has resulted in steering flow out of the W/SW and will allow for even warmer Max temps into the mid/upper 80s inland today while the Atlc Coast Sea Breeze front will be pinned to the I-95 corridor from JAX northward while reaching the St. Ridge remains in place south of the region as weak frontal boundary approaches from the north across the SE U. Still low chances that the low CIGS/VSBYS reach the rest of NE FL TAF sites.
Expect some light snow to develop in the highest elevations of the Black Hills this afternoon with light accumulation possible. Couple of troughs extended from lows into southeast MT and south central SD. Water vapour has upper low spinning over central AZ, which is a bit further south than previous guidance showed. Northern branch of upper trough moving across MT. Today and tonight, upper low moves into the TX panhandle by 12z Wednesday which is a bit slower and further south than previous guidance. Inverted trough feature extending north into the CWA will be focus for precipitation today and tonight given modest synoptic scale lift and low level frontogenesis. Boundary layer temperature forecast shows wet bulbs 1-2C warmer than yesterday and thus, snowfall looks to be limited to the very highest elevations.
1224 PM EDT Tue Mar 28 2017 Weak low pressure will move across the Middle Atlantic region today and then offshore tonight.
with weaker storms driven by low amplitude upper level troughs. A long wave ridge continues to build into the west coast this morning. The ridge will bring dry and warmer weather to the area today. The ridge axis will flatten and break to the east of the area late tonight into early Wednesday. A short wave riding up the back side of the ridge will move onshore to the north of the area Wednesday morning. A warm front will move onshore Tuesday night. followed by a trailing cold front Wednesday afternoon.
Dry and mild conditions expected today as high pressure builds aloft.
Light north winds continue in the wake of yesterday's cold front, but temperatures should still climb into the upper 60s to low 70s across the forecast area.
Models continue to show the upper trough amplifying into the Four Corners region through the day, with a midlvl closed low developing over northern New Mexico by this evening. The 00Z guidance does show less QPF in general across the region compared to yesterdays runs, as the low center is further south. Not confident we will see snow accumulating on the road surfaces through the afternoon outside of the mtns and southern Laramie Range, especially considering the higher sun angle of late March and not overly heavy snow rates. This may change by the evening as colder sfc temps and lack of solar radiation allow the road sfc temps to cool to near freezing. Stay in an unsettled pattern with low pressures systems tracking to our south every 2-3 days.
936 AM EDT Tue Mar 28 2017 Low pressure crosses and then moves away today, with lingering NW flow showers.
1217 PM EDT Tue Mar 28 2017 Showers will plague the Upper Ohio Region this afternoon with crossing low pressure. Low pressure system has moved east into central Pennsylvania. As high pressure moves over the Great Lakes, cooler and drier air will filter over the region.
959 AM EDT Tue Mar 28 2017 Low pressure moving through the Ohio Valley will offer a continued chance of light showers this morning. High pressure will build in for the middle of the week, providing dry weather.
