SUBJECTIVE 00Z UPPER AIR ANALYSIS INDICATES A SLOW-MOVING AND BROAD UPPER LOW CENTERED NEAR THE WY/CO/UT BORDER AREA. ALL BENEATH A PREVAILING RIDGE ACROSS CANADA. WITH A LACK OF A STRONG UPPER-LEVEL JET TO HELP NUDGE THE LOW. THE LOW WAS CENTERED OVER SD. MID-LEVEL TEMPERATURES WERE ON THE COOL SIDE BENEATH THE UPPER LOW. WITH 850MB TEMPS IN THE LOWER SINGLE DIGITS IN THE NORTHERN HIGH PLAINS BUT UPPER SINGLE DIGITS TO DOBULE DIGITS FROM ND/NORTHEASTERN SD INTO THE UPPER MIDWEST AND MS RIVER VALLEY. HAVE LOWERED TEMPS A TOUCH UNDER HIGH PRESSURE AND LIMITED MIXING. EVEN WITH UPPER LOW BEGINNING TO EJECT ACROSS THE PLAINS. CHANCES OF RAIN INCREASE QUICKLY ON WEDNESDAY AS UPPER LOW SLIDES ACROSS NEB/IA. JUST AHEAD OF THE UPPER LOW AND IN PROXIMITY TO THE 850MB LOW.
330 AM PDT TUE APR 19 2016 HIGH PRESSURE WILL CONTINUE TO BUILD OVER THE AREA WITH MAINLY CLEAR SKIES AND UNSEASONABLY WARM TEMPERATURES. THE HIGH WILL BREAK DOWN ON WEDNESDAY ALLOWING FOR A COOLING TREND TO TAKE PLACE.
308 AM PDT TUE APR 19 2016 HIGH PRESSURE ALOFT NEAR THE WEST COAST WILL WEAKEN WITH SLOW COOLING SPREADING INLAND THROUGH WEDNESDAY.
A HIGHLY ANOMALOUS BLOCKED PATTERN WAS IN PLACE WITH RIDGES OVER THE ERN USA AND ALONG THE W COAST. A STALLED CUT-OFF LOW WAS ALONG THE WY/CO BORDER. THESE TWO VORT MAXIMA WILL PINWHEEL AROUND THE LOW WITH THE UT VORT MAX ORBITING THE S SIDE OF THE LOW THRU SRN CO TONIGHT. SURFACE: A STRONG COLD FRONT EXTENDED N-S THRU THE PLAINS FROM THE DAKOTAS ALONG THE ERN BORDERS OF NEB/KS DOWN INTO TX. A PIECE OF THE HIGH WILL BREAK OFF AND SETTLE OVER THE CNTRL PLAINS TONIGHT AND TOMORROW. THE UPPER LEVEL LOW AFFECTING THE AREA THE PAST COUPLE OF DAYS WILL MOVE INTO THE FORECAST AREA TUESDAY NIGHT AND MOVE TO THE EAST ON WEDNESDAY. AS THE LOW MOVES INTO THE AREA THERE IS A CHANCE FOR SOME PRECIPITATION. BY WEDNESDAY NIGHT THE UPPER LOW IS IN IOWA.
345 AM EDT TUE APR 19 2016 LOW PRESSURE AND ASSOCIATED SHOWERS WILL GRADUALLY MOVE EAST OF THE AREA TODAY.
TONIGHT THROUGH WEDNESDAY NIGHT A LARGE UPPER LOW PRESSURE SYSTEM IS SITUATED OVER THE ROCKIES AND MOVING EVER SO SLOWLY TO THE EAST. THIS LOW IS BEING BLOCKED BY AN UPPER RIDGE OVER THE EAST. THE UPPER LOW WILL MOVE INTO THE PLAINS WEDNESDAY AND INTO THE MIDWEST WEDNESDAY NIGHT. A COLD FRONT IN EASTERN OKLAHOMA IS MOVING SLOWLY EAST AND WILL STALL IN EASTERN OKLAHOMA TONIGHT.
349 AM CDT TUE APR 19 2016 Water vapor imagery depicting a well defined conveyor belt of moisture flowing into the region as a result of deep layered south-southwesterly flow well ahead of the Rockies upper low. At that time a rather prominent short wave trof will begin spreading large scale ascent from western MO into central MO as it rotates northeastward in advance of the slowly migrating upper low. The precipitation threat should then diminish overnight as the upper trof becomes more postively tilted and migratory, and as deeper moisture is transported into the OH/TN Valleys in advance of the advancing surface cold front.
140 AM EDT TUE APR 19 2016 A WEAK COLD FRONT IS EXPECTED TO BRING SOME CLOUDS AND COOLER TEMPERATURES TODAY. DECOUPLING THE LOWER ATMOSPHERE RESULTING IN CALM WINDS AT THE SURFACE. EARLY MORNING TEMPERATURE READINGS AGAIN DEPEND ON LOCATION AND TOPOGRAPHY WITH URBAN HEAT ISLANDS AND HIGHER ELEVATIONS WARMER THAN COOL DRAINAGE AREAS IN THE VALLEYS. A WEAK FRONT WILL DROP IN FROM THE NORTH ERODING THE GRIP OF THE UPPER-LEVEL RIDGE THAT HAS BEEN IN PLACE. BUT GIVEN THE COPIOUS DRY AIR NEAR THE SURFACE AND THE HIGH PLACEMENT OF THE DEEPER MOISTURE ALONG THE FRONT. COOLER AIR BEHIND THE FRONT WILL BRING LOWS TONIGHT BACK DOWN CLOSER TO AVERAGE. TAX HIGH PRESSURE WILL DOMINATE WITH DRY AND SEASONAL CONDITIONS TUESDAY NIGHT INTO MOST OF WEDNESDAY.
UPPER LEVEL LOW OVER THE NORTHERN GREAT PLAINS NOT LOSING ITS INFLUENCE AS EASILY AS PREVIOUSLY THOUGHT. NO SIGNIFICANT WIND EXPECTED UNDER THE UPPER LEVEL RIDGE.
328 AM EDT TUE APR 19 2016 AN UPPER-LEVEL STORM SYSTEM AND COLD FRONT WEST OF THE MISSISSIPPI RIVER WILL BRING SOME PASSING HIGH CLOUDS INTO THE REGION TODAY. WITH HIGH PRESSURE AT THE SURFACE AND THE UPPER-RIDGE STILL BEING THE PRIMARY INFLUENCE ON OUR WEATHER. READINGS IN THE LOWER 80S WILL BE COMMON IN MOST AREAS BY THIS AFTERNOON.
Upper ridge will begin to slowly break down in response to closed upper low moving into the eastern Plains through mid week. The initial breakdown in the ridge will result in an increase in mid and upper level clouds, however we will remain dry today and tonight. Temperatures will be a degree or two cooler than yesterday, but overall will still be in the 80-84 degree range. Some of the lower resolution models try to hint at some precipitation chances this evening across our NE along a mid level deformation axis. So, not expecting anything to hit the ground and will lean on the higher res dry solutions in line with previous forecasts. Upper ridge axis will be east of the region by Wednesday, with SW flow through a deeper layer allowing more moisture into the Ohio Valley.
419 AM CDT TUE APR 19 2016 UPPER LOW WILL DOMINATE CONDITIONS THROUGH THE SHORT TERM. OVERNIGHT THE CWA WILL SEE ANOTHER PLUME OF SOME MID LEVEL MOISTURE HEADED INTO THE REGION AHEAD OF THE NEXT WEAK WAVE PIVOTING AROUND THE UPPER LOW.
541 AM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE THROUGH EARLY THIS MORNING.
127 AM EDT TUE APR 19 2016 HIGH PRESSURE OVER THE REGION WILL WEAKEN WILL WEAKEN ALLOWING A WEAK COLD FRONT TO DRIFT SOUTH ACROSS THE AREA LATE TONIGHT.
207 AM CDT TUE APR 19 2016 TEMPS AT 2 AM WERE MAINLY IN THE LOW/MID 50S WITH DEWPOINTS BETWEEN 45 AND 50 DEGREES. OTHERWISE THE OMEGA BLOCK IS FINALLY STARTING TO BREAK DOWN BUT MOST OF THE SERN US IS STILL UNDER THE INFLUENCE OF AN UPPER RIDGE. THE UPPER RIDGE AXIS WILL BE MOVING ACROSS THE SERN COASTLINE WHICH WILL ALLOW AN UPPER LOW/CDFNT TO APPROACH THE CWA.
1100 PM PDT MON APR 18 2016 New Aviation Discussion A slight cooling trend through Wednesday as high pressure weakens and onshore flow returns.
216 AM MDT TUE APR 19 2016 THE LOW. TUESDAY NIGHT WITH THE LOW ON THE PLAINS THE NEXT SPOKE OF ENERGY WILL RAKE NW COLORADO PRODUCING SOME LIGHT SNOW FROM ASPEN-VAIL NORTHWARD.
555 AM EDT TUE APR 19 2016 CLOUDS WILL INCREASE TODAY AND TEMPERATURES WILL BE COOLER BUT DRY CONDITIONS WILL CONTINUE UNTIL WEDNESDAY.
122 AM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE SOUTH FROM THE GREAT LAKES TONIGHT INTO THE OHIO VALLEY TUESDAY CAUSING COOLER TEMPERATURES TO SPREAD INTO THE AREA.
631 AM EDT TUE APR 19 2016 A WEAK COLD FRONT WILL PUSH SOUTH INTO THE AREA THROUGH TODAY BEFORE EVENTUALLY LIFTING BACK TO THE NORTH AS A WARM FRONT WEDNESDAY INTO WEDNESDAY NIGHT.
Warm and dry high pressure will remain over the Northern Rockies, at least through Wednesday.
HIGH PRESSURE CENTERED OVER GEORGIA THIS MORNING WILL GRADUALLY BUILD SOUTHEAST WITH ONSHORE FLOW FORECAST TO BE LESS BREEZY THIS AFTERNOON. DEEP LAYER HIGH PRESSURE RIDGE ALONG THE EASTERN SEABOARD WILL SLOWLY START TO MOVE OUT TO SEA ON THU. THE MODEL TREND LOOKS A LITTLE SLOWER WITH PASSAGE OF UPPER TROUGH AXIS AND THE ASSOCIATED DRYING. EVEN AFTER PASSAGE OF UPPER TROUGH. HIGH PRESSURE BUILDING CLOSER TO THE REGION WILL ALLOW WINDS TO DECREASE FURTHER TODAY TO AROUND 10-15 KTS. A WEAKENING HIGH PRESSURE RIDGE WILL SETTLE NEAR OUR NORTHERN WATERS WED AND PRODUCE A 10 KNOT OR LESS EASTERLY WIND FLOW IN THE NORTH. THE RIDGE WILL SHIFT OFFSHORE THU AND SOUTHEAST FLOW 10 KNOTS IS INDICATED IN THE NORTH AND 15 KNOTS IN THE SOUTH.
THE UPPER LEVEL LOW THAT HAS BEEN SUPPORTING STORMS STILL REMAINS BACK TO THE NORTHWEST.
653 AM EDT TUE APR 19 2016 A COLD FRONT WILL MOVE THROUGH EARLY THIS MORNING.
412 AM EDT TUE APR 19 2016 A MAINLY DRY COLD FRONT IS CROSSING THE REGION EARLY THIS MORNING. HIGH PRESSURE WILL PROVIDE MOSTLY SUNNY SKIES THIS AFTERNOON AND ON WEDNESDAY AS TEMPERATURES COOL TO MORE SEASONAL LEVELS.
1152 AM EDT THU AUG 4 2016 High pressure, along the east coast, will keep our weather seasonably warm, and mostly rain free, into Friday.
Expect no precipitation today, but due to the cooler air brought in by the departing trough, highs will remain below normal today. Templer Previous Discussion - Synoptic Setup: Cool air lies spilled over the high Plains of Montana, the Dakotas, and the Canadian Plains behind and exiting trough. A large hot high pressure heat dome is building over Intermountain West with a ridge starting to develop over the Pacific Northwest. North of this a closed low is meandering down the British Columbia Coastline. Today through Friday Night: Ridge to the west will continue to develop as and slowly shallow out the cool air across the region starting today. The encroaching ridge will generate stable and dry conditions for the next 48 hours.
1006 AM EDT THU AUG 4 2016 A cold front will push across the area Friday night.
/ISSUED 312 AM CDT THU AUG 4 2016/ The summer heat will continue across the entire region through the weekend as upper level high pressure remains parked over the state. Large scale subsidence under the ridge will keep clouds and rain chances at a minimum overall.
In addition, a weak cold front will enter the Oklahoma Panhandle and northwest Texas Panhandle late this evening, with winds becoming north at KGUY and KDHT. Water vapor shows a subtle upper level low spinning over the Four Corners region - temporarily shifting the flow more northwesterly across the Panhandles.
/issued 357 AM CDT THU AUG 4 2016/ (Today and Tonight) Not much change to the ongoing forecast, with the upper level high still in place.
A lingering stationary trough is parked across north Florida with high pressure dominating south Florida and the Florida Keys. The dry air moving over the area along with a deep layer high pressure will control the environment over the Keys at least through the short term. High pressure is and will persist through the weekend with a weakening pressure gradient at the surface.
Cooler than seasonal norm temperatures and more extensive night and morning inland stratus coverage can be expected for the remainder of the week and upcoming weekend.
1035 AM EDT Thu Aug 4 2016 High pressure east of Long Island will move further off the coast today.
706 AM EDT THU AUG 4 2016 A cold front will push across the area Friday night.
740 AM EDT THU AUG 4 2016 High pressure slowly slides offshore through Friday.
1051 AM CDT THU AUG 4 2016 Numerous showers and storms continue to impact the southwest portion of the forecast area this morning, aided by a compact upper low near the Indiana/Kentucky border and abundant low- and mid-level moisture. We expect the ongoing activity to continue to diminish in coverage and intensity later this morning as the upper low pulls eastward. High-resolution models generally support this scenario and show the highest coverage of convection across the Cumberland Plateau. We may have to re-visit high temperatures again early this afternoon as clouds and ongoing convection may keep highs cooler than forecast, especially across the southwest. An upper level low pressure system will move across the area today with a good chance for TSRA.
624 AM CDT THU AUG 4 2016 The primary focus with the short term forecast is on the cold front currently sliding across nw and northern Nebraska. Highs today will be noticeably cooler with upper 70s across our north.
VFR will prevail today courtesy of broad high pressure overhead in the middle layers of the atmosphere. /issued 356 AM CDT THU AUG 4 2016/ SHORT TERM (Today through Friday): Broad 500 mb high pressure will remain centered over the Lone Star State and extended over Deep South Texas and the Rio Grande Valley throughout the forecast period.
Upper short wave trough on satellite imagery this morning is currently rotating into the southern Manitoba province. In it's wake, a cold front will surge southeast across the western high and central plains regions through the afternoon and evening. Lapse rates in the low levels are dry adiabatic with ample dry air towards the sfc as dewpoints mix to the upper 60s.
942 AM EDT THU AUG 4 2016 High pressure slowly slides offshore through Friday.
do anticipate enough differential heating as clouds thin this afternoon to aid convective initiation over the higher terrain across the south initially, and the lower elevations late day as cells trend to become outflow dominated while slowly working off the terrain. An upper low currently off the NorCal coast will gradually translate east tonight through tomorrow, with southwesterly flow aloft downstream aiding to draw this moisture north across the area by tomorrow afternoon/eve.
Pacific upper low taking position near 40/130 where it will advect monsoon moisture northward through Nevada into our southern CWA zones late tonight through Friday night.
1138 AM EDT THU AUG 4 2016 High pressure slowly slides offshore through Friday.
1018 AM CDT THU AUG 4 2016 Still seeing a few scattered showers across the far southeast CWA in vicinity of the departing cold front. Will see cooler conditions today along with much less humidity.
Surface temperatures are running about 5 degrees warmer today than same time yesterday, so middle to upper 90s likely everyone. Weather maker today will be a short wave trof tracking east across Kentucky. A cluster of storms on the southern edge of the short wave trof was approaching northwest Alabama. 19 Generally scattered showers and thunderstorms are expected through the week with highs in the lower to middle 90s.
Broad ridging aloft centered over the Southern Plains continues to dominate the region in the near term.
A strong cold front continues to track across southeast WY and the western NE Panhandle early this morning. H7 temps are progged to fall below +10C over the high plains by 21z, and good saturation in the H7-H3 layer suggests persistent mid level cloud cover, and limited surface heating.
941 AM EDT THU AUG 4 2016 Very warm and humid conditions along with periodic shower and thunderstorm chances are expected until the passage of a Friday night cold front.
1107 AM EDT THU AUG 4 2016 A ridge of high pressure overhead will keep it mainly dry and seasonably warm into Friday.
The second round looks to develop along the cold front this afternoon. The cold front looks to enter the northwest portion of Iowa b/t 18-21z and transition southeast through the afternoon hours and by around 00z Friday it looks to be located from near Cass County to Black Hawk County.
Latest UA analysis and WV imagery shows sprawling upper lvl ridge over the srn plains east toward the lower MS Valley. a weak ridge of subtropical high pres continues acrs the nrn Gulf, with lt s/sw or near calm winds noted over the region early this morning. 24 Few changes to the fcst as the upper ridge remains the primary influence on our weather in the near term. With dewpoints fcst to remain in the lower to middle 70s acrs much of the area, resultant heat index values will be between 103 and 108 degrees in many locations. The upper lvl anticyclone will move little through the weekend, keeping hot humid conditions in place over the area and limiting daily convection.
As mentioned earlier the trough is moving through, however some of the monsoon moisture has edged its way into the Sierra and parts of the SJV and Kern Co desert areas with a few showers this am. Upper Ridge has centered itself over central TX with a weakening ridge axis across central CA. Weak upper low off Eureka CA is progged to move inland later this morning with an associated trough moving through Central CA this evening. The trough pushes through with strong onshore flow and cooler temps across the region on Friday. Some gusty winds are possible with the trough. However the real noticeable factors will be cooler temps and better air quality in the SJV.
Under full insolation this morning, temperatures were running a degree or two warmer than expected and will have no problem achieving the forecasted hot afternoon highs. For the most part though, convection will be isolated today and Friday as broad scale subsidence beneath the persistent ridge has finally dried the column to PWs less than 2 inches over the northwest half.
1217 PM EDT THU AUG 4 2016 High pressure slowly slides offshore through Friday.
Diurnal heating NE of the current showers over inland NE FL will support Max Temps in the lower 90s with a few mid 90s possible in areas that don't receive rainfall until later in the day.
Should see a few high based cumulus clouds develop over the higher terrain of central and east-central Oregon this afternoon as subtropical moisture begins to push into the area. High temps this afternoon should run 8 to 10 degrees warmer than yesterday.
Cold front will approach from the northwest tonight, reaching the Illinois River by 12z Fri. Cold front will sink southward through central Illinois on Friday, bringing scattered showers and thunderstorms.
Mid-level heights also show the trough currently swinging through Montana with a broad low stratus deck slipping south from southern Saskatchewan and Manitoba. Templer Previous Discussion - NE-SW oriented upper level trough will move south across Montana today. It will pass through Northeast Montana this morning and gradually push the main band of precipitation ahead of the trough to the south. High pressure moves into the area tonight and Saturday with dry weather. Highs on Saturday will be about 10 degrees warmer than today.
Northern California currently under upper level northeast flow between high pressure over the Pacific Northwest and a low pressure system off the Socal coast. A shift of the upper low slightly farther south today should shift Sierra thunderstorm activity a bit south as well.
500 mb ridging will build over the RGV through the next 24 hours which will tend to lower down the deeper layer moisture values. /issued 407 AM CDT FRI AUG 19 2016/ SHORT TERM (Now through Saturday):500 mb ridging will remain in place over Gulf of Mexico.
Mean upper level troughing will persist over the northern plains over the next ten days. A southern stream upper level trough will move from the southern Rockies toward the southern high plains by mid this week. The first of these systems will pass across western Kansas today and tonight with a strong cold front.
522 AM MDT FRI AUG 19 2016 Upper level analysis shows a broad trough over much of the northern CONUS, with the next wave to affect the northern plains currently over MT. The next upper wave will pass over the region today, bringing another round of showers/storms, breezy northwest winds, and cooler air. Highs will be well below average, ranging from the lower 60s across northwestern SD and northeastern WY to the lower 70s across south central SD. High pressure will move into the region behind this system. Dry weather and a warming trend will begin on Saturday, with highs in the lower 70s. Deep layer ridging will ensue Sun with waa continuing into Mon.
Much of the shear in lagging behind the front behind the highest MUCAPE values. Forecast models are edging into two camps, the NAM and GEM are rather strong with a heavy rainfall across much of the local area with the low tracking across western Wisconsin. The ECMWF and the GFS take the low further to the northeast and don't deepen it until is over eastern Lake Superior, which means less rain for the local area. Cooler air will also arrive with the low pressure system, making it feel more like autumn a times.
A few light showers will be around the TAF sites this morning, but most of the thunderstorm activity should come in the afternoon as a midlevel trough moves across the area, mainly between 18z and 00z.
The cloud cover will also result in cooler temperatures once again. with highs reaching the low to mid 80s in most spots this afternoon. Chattanooga Airport, TN 87 73 87 73 / 70 40 60 50 Knoxville McGhee Tyson Airport, TN 85 70 83 71 / 70 40 60 50 Oak Ridge, TN 84 71 84 71 / 70 40 60 50 Tri Cities Airport, TN 82 67 83 68 / 60 40 50 50.
An upper level trough dipping into the Ohio and Tennessee Valleys. and associated surface cold front. As the upper trough and surface front push southward over the weekend, that band should likewise move southward into our neck of the woods.
Atlantic ridge axis will be draped across central FL resulting in good boating conditions and very sparse storm coverage.
Meanwhile, early visible satellite photographs show skies range from mostly sunny in the Lower Keys to partly to mostly cloudy along the rest of Keys communities. Surface wise, a decaying Western Atlantic ridge extends across the Florida Peninsula, resulting in mostly east winds of 10 knots on our marine district.
942 AM EDT FRI AUG 19 2016 High pressure will crest over the region today.
Added VCTS to southern TAF sites, as this area is closest to remnant cold front. /issued 350 AM CDT FRI AUG 19 2016/ (Today and Tonight) The wet pattern continues across west central Texas through the short term as a weak shear axis or trough remains over the central part of the state.
However, if you have plans in the high Sierra, you will be much closer, if not in, the smoke layer and the air quality will be worse. /Issued 207 AM PDT FRI AUG 19 2016/ A weak area of low pressure over southern California will produce isolated afternoon and evening thunderstorms today, mainly south of Highway 50.
Current surface analysis places high settling into central Montana, while cold front stretches through the midwest into the central plains. Upper level analysis places low over eastern Hudson Bay with deep trough stretching into the northern plains. Broad area of showers have developed along/ahead of the trough over eastern into south central Montana, and continue to slowly shift into western North Dakota. rain shower activity will be on the increase, particularly over southwest into south central North Dakota where greatest broad scale lift is noted with the advancing trough. Chances gradually lessen overnight over the south central as the base of the trough pushes east- southeast. Low precipitation chances linger over the James River Valley with cyclonic flow in place as base of trough attempts to cut off as it pushes east.
934 AM EDT FRI AUG 19 2016 High pressure will build into the region bringing fair weather into Saturday. Trof advances ewrd on Sat and begins to lwr hgts and incrs moisture in the area.
The cold front is nearing KDHT at this time and will push through KGUY soon and KAMA near 23Z. An upper trough will track east out of the central and southern Rockies today and tonight. the cold front and increasing chances for convection is the main reasons for max temps being lowered a category or so today.
Northwest flow aloft in response to an upper level trough developing over the Midwest will usher in slightly cooler air today.
A dry cold front will move into northern Utah and southwest Wyoming this morning, ushering in a drying trend that will continue through Saturday. The Canadian trough is moving down into the eastern half of Montana this morning. As it tracks south, the system brings a cold front into northern Utah this morning, resulting in a northerly flow aloft. Under northerly flow, the forecast area will see some drier air getting advected in, though showers and thunderstorms are expected over the higher terrain. The drying will continue tomorrow with ridging moving in, though a few showers and storms are possible down in southern Utah.
A cold front will move south through area Saturday morning with gusty winds behind it. Expect widespread convection to persist over the Big Bend region into the Lower Trans Pecos this afternoon.
