604 PM CDT WED AUG 31 2016 Band of showers and thunderstorms will continue to move southeast late this afternoon and will be south of the CWA by early this evening as low level winds begin to advect cooler and drier air into the area. Some diurnal cumulus is expect to develop over the northeast half of the CWA by afternoon as a weak mid level trough passes through the area. Expect highs tomorrow to be closer to warmer NAM MOS guidance which has values closer to 80 degrees in most areas. Carney High pressure remains in control of the weather through the weekend.
906 PM EDT WED AUG 31 2016 A cold front will push southeast across the commonwealth overnight into early Thursday, bringing a chance of showers.
Main concerns for overnight will continue to revolve around heavy rainfall potential, gusty winds, and potential for a few rotating cells as the low-level wind shear profilers become a bit more favorable.
1038 PM CDT WED AUG 31 2016 At 2 PM, a short wave trough was moving southeast Minnesota and central Wisconsin. Temperatures were in the lower 70s north of Interstate 94 and and in the mid and upper 70s across the remainder of the Upper Mississippi River Valley.
931 PM CDT WED AUG 31 2016 Backdoor cold front that has gradually pushed SW across the forecast area earlier today, has led to diminishing shower trends across most of the forecast area this evening. Already seeing signs of this drier air across NW MO where surface dewpoints falling into the low 60s. 0 inches) continues along and south of this shear axis, which will be shunted very slowly southward Tonight, as upper troughing digs into the Upper Mississippi Valley/Great Lakes.
1207 AM EDT THU SEP 1 2016 A cold front will slowly move southeast off the Downeast coast overnight.
749 PM EDT Wed Aug 31 2016 A cold front with scattered showers and thunderstorms will pass through the region tonight ushering in cooler and mainly dry weather for Thursday onward into the first half of the upcoming weekend.
/issued 226 PM CDT FRI JUL 1 2016/ We are getting to the summer doldrums which means high pressure is the dominant weather feature. All models are showing an upper high either overhead or very close by giving us hot and mostly dry weather with the exception of a few storms mainly over the Davis and Guadalupe Mountains. A weak cold front will move into the northern Permian Basin Sunday but will not advance farther south than around Lamesa before stalling.
112 AM EDT SAT JUL 2 2016 A cold front will pass over the area overnight into early Saturday, before stalling across North Carolina.
This is due to a warm front being pushed northward into northern Kansas. Lows tonight are expected to range from the lower 60s across west central Kansas to upper 60 across south central Kansas. For Saturday night, a cold front will continue to move east into central Kansas with lingering strong to severe thunderstorms mainly east of Dodge City into parts of south central Kansas.
154 AM EDT SAT JUL 2 2016 High pressure will build into the area today. Water vapor imagery showing short wave pushing eastward into the eastern great lakes while surface analysis has cold front moving through the Ohio valley. Visible satellite indicating diminishing trends in stratocu cloud cover and expect this to continue as high pressure builds into the region. Potent Theta-E ridge extending up into central Indiana will be coincident with PW exceeding 2 inches which will set the stage for a convective complex producing a significant rain event.
Weak high pressure over Central and Southwest Montana will gradually break down as a low pressure trof over the eastern Pacific moves towards the Rockies. The air mass will generally remain quite dry through the period although water vapor indicates moisture aloft will be crossing the Rockies tonight ahead of the approaching low pressure system. Winds aloft strengthen Sunday as the low pressure system moves over the Pacific Northwest. Cooler air associated with the low pressure system will begin to cross the Rockies Sunday but will have little effect across the zones and max temperatures will again be in the upper 80s.
Low pressure disturbance over the Gulf of Alaska moves into British Columbia Sunday and continues slowly east the next several days.
555 AM EDT SAT JUL 2 2016 High pressure will move across the lower great lakes today.
620 AM EDT SAT JUL 2 2016 as expansive high pressure over the Upper Mississippi Valley will gradually build across the Ohio Valley. A large area of high pressure centered over the Mid Western states will expand across the Lower Great Lakes today. mainly clear skies with lows dipping into the lower to mid 50s. A slow moving upper low over Quebec and ridging over the Northern Plains states will yield a confluent flow over the Lower Great Lakes region through the remainder of the extended Independence Day Holiday weekend. While temperatures will average near normal Sunday, slight warming aloft will lead to highs on Independence Day in the lower to mid 80s.
The low/mid level pattern will remain fairly similar to yesterday, with southwesterly steering flow in place. Isolated to scattered showers and storms are forecast across southeast Georgia, with the highest PoPs near the coast where the higher moisture remains. Temperatures will rise into the low/mid 90s across southeast Georgia, with heat indices of 100-105 degrees.
115 AM EDT SAT JUL 2 2016 An upper trough will push a cold front south across the region through Saturday. These originated along an axis from near Hendersonville to just northwest of the Piedmont Triad, seemingly all in response to a slight vort max rounding the eastern CONUS trough. Highs Saturday are progged to be a degree or two warmer than those today.
With diminishing cloud cover and light winds, lows will be a bit cooler than this morning, and should mainly be in the lower to mid 50s.
333 AM EDT SAT JUL 2 2016 High pressure will move across the lower great lakes today.
312 AM EDT SAT JUL 2 2016 Weak summertime flow pattern will continue with a weak short wave passing through the area early in the weak followed by increased ridging. At 230 PM Saturday: An upper trough will deamplify over the eastern seaboard today, resulting in zonal flow from the mid MS River Valley to the NC coast that will persist through tonight. At the surface, a slow moving cold front will stall over our area today, somewhere in the vicinity of the NC and SC border, remaining there through tonight. Temperatures will run slightly above normal as the upper ridge flattens.
Broad upper level high pressure system will continue over the southeast U.
and that seems reasonable since mid level trough axis is expected to shift eastward. Highs on Sunday should be warmer than today. then highs in the lower or mid 80s are likely for Independence Day. The mid tropospheric pattern for much of this period will feature a trough over the far western United States and a ridge from northern Mexico toward the Ohio Valley. The overnight hours will generally have the higher chances. With surface dewpoints likely climbing back to the lower or mid 70s.
A lee trough axis will extend southwest of the low into southwestern Kansas. High temperatures will be very uncertain depending on how far north the actual warm front makes it, and effects of outflow from this mcs. Will show a conrast of lower 80s near the warm front, to the mid 90s near the Oklahoma border. Storm training with intense, potentially excessive hourly rainfall rates, will be possible with a slowly veering low-level jet becoming more aligned with the southward advancing cold front. High chances for thunderstorms will linger in southeastern Kansas Sunday into Sunday night, as the slow-moving cold front interacts with an anomalously moist, unstable airmass.
High pressure will remain over the western Great Lakes today and tonight. For tnt skies may become partly cloudy toward the IL border as low pressure moves across the central Great Plains to the Kansas City area.
The NAM has a closed low while the GFS and ECMWF are open waves. Expect there to be cloudy skies across the area Saturday and temperatures will be quite a bit cooler than recently. The clouds will be kind of slow to move out of the area Sunday and temperatures will remain on the cooler side.
SHORT TERM (Now through Sunday): Strong high pressure will remain over the Gulf in the short term. A mid level short wave trough will move out of the Rockies and into the high plains, with associated low pressure at the surface. Meanwhile, ridging will remain in place overhead, maintaining subsidence and hot weather. Max temps for today will only be as low as the 80s at the beaches, rising quickly inland to the lower 90s near the coast and reaching the century mark and above by U. Low temperatures tonight will range from the mid and upper 70s to the lower 80s, under mostly clear skies and along with a persistent light to moderate wind. Low pressure will deepen upstream over north and west Texas under an advancing mid level trough, maintaining breezy afternoon winds.
258 AM EDT SAT JUL 2 2016 High pressure will build south of the region today through tonight and will shift offshore on Sunday.
A weak low pressure system will quickly move through the region today and weaken the ridge. One effect will be cooler temps. High temps will be 5 to 7 degrees cooler and remain below 90 in the valleys of western Montana and north central Idaho, the exception being the lowest valleys, such as Hells Canyon.
651 AM EDT SAT JUL 2 2016 High pressure will remain across the region today and tonight.
Temps will turn a bit warmer given the upper ridge and diminishing easterly sfc winds.
358 AM EDT SAT JUL 2 2016 as expansive high pressure over the Upper Mississippi Valley will gradually build across the Ohio Valley. A large area of high pressure centered over the Mid Western states will expand across the Lower Great Lakes today. mainly clear skies with lows dipping into the lower to mid 50s. A slow moving upper low over Quebec and ridging over the Northern Plains states will yield a confluent flow over the Lower Great Lakes region through the remainder of the extended Independence Day Holiday weekend. While temperatures will average near normal Sunday, slight warming aloft will lead to highs on Independence Day in the lower to mid 80s.
201 AM EDT SAT JUL 2 2016 A cold front exits to the east overnight, and then high pressure builds in from the west on Saturday before moving offshore on Sunday. Line of showers with the cold front has weakened greatly over the past hour as the line heads into a region of less CAPE. Heights will rise on Saturday as high pressure builds in from the north and west. Radiational cooling possible for areas across the Lower Hudson Valley, interior portions of southern CT, as well as eastern Long Island. Lows there could drop into the low 50s. Otherwise, lows will be in the low to mid 60s, and possibly into the upper 60s in NYC.
345 AM EDT SAT JUL 2 2016 A weak cold front continues to drift southward across southeast Kentucky, visible only by a weak wind shift to the north-northeast and slight lowering of dewpoints. Low clouds and patchy fog which will develop over southeast Kentucky this morning as shifting winds bank up low level moisture against the higher terrain will scatter out by late morning leaving considerable high level cloudiness.
Tonight Through Saturday The high pressure ridge aloft that has dominated the weather the past few days has begun to weaken and shift east into the Central Plains as a short wave trough of low pressure moves into the Pacific Northwest. The movement of the ridge will take the fetch of subtropical moisture with it so showers and afternoon and evening thunderstorms will begin to decrease on Saturday. the Pacific trough will bring a weak surface cold front so the amount of warming will be counter balanced by the cooling from the cold front.
338 AM EDT SAT JUL 2 2016 High pressure centered over northern Illinois early this morning will build eastward and it should bring dry weather conditions for today and Sunday.
139 AM EDT Sat Jul 2 2016 Showers a few thunderstorms will come to an end by late evening as a cold front moves across the area.
251 AM PDT SAT JUL 2 2016 An upper low will continue to bring the threat for thunderstorms mainly south of Highway 50 today, before drier conditions return for the remainder of the holiday weekend. The upper low which brought the thunderstorms, gusty outflow winds and areas of blowing dust to west central NV yesterday is projected to slide farther south today, shifting the primary focus for convection to areas south of US-50 this afternoon and evening. For Sunday, this low will weaken further while dry and more stable air mass spreads southward.
148 AM EDT SAT JUL 2 2016 High pressure will build into the Great Lakes, offering dry weather Saturday. Showers and thunderstorms will return Sunday ahead of low pressure approaching from the the west. With high pressure and drier air building in, temperatures are expected to drop to the middle and upper 50s. Highs will be around 5 degrees below normal with highs ranging from the upper 70s north to the lower 80s south. Lows to range from the upper 50s north to the lower 60s south. A warm front will be extending into the ILN area Sunday ahead of low pressure centered to the west.
645 AM EDT SAT JUL 2 2016 Weak summertime flow pattern will continue with a weak short wave passing through the area early in the weak followed by increased ridging. At 230 PM Saturday: An upper trough will deamplify over the eastern seaboard today, resulting in zonal flow from the mid MS River Valley to the NC coast that will persist through tonight. At the surface, a slow moving cold front will stall over our area today, somewhere in the vicinity of the NC and SC border, remaining there through tonight. Temperatures will run slightly above normal as the upper ridge flattens.
/issued 433 AM CDT SAT JUL 2 2016/ SHORT TERM (Now through Sunday): Strong high pressure will remain over the Gulf in the short term. A mid level short wave trough will move out of the Rockies and into the high plains, with associated low pressure at the surface. Meanwhile, ridging will remain in place overhead, maintaining subsidence and hot weather. Max temps for today will only be as low as the 80s at the beaches, rising quickly inland to the lower 90s near the coast and reaching the century mark and above by U. Low temperatures tonight will range from the mid and upper 70s to the lower 80s, under mostly clear skies and along with a persistent light to moderate wind. Low pressure will deepen upstream over north and west Texas under an advancing mid level trough, maintaining breezy afternoon winds.
427 AM EDT SAT JUL 2 2016 High pressure will remain across the region today and tonight.
328 AM CDT SAT JUL 2 2016 Early morning water vapor imagery/RAP analysis has a 593dam ridge axis from the western Gulf and over the Southern Plains resulting in a mid level northwest to north flow over our CWA. Early morning surface analysis had a stalled cold front draped across northern Mississippi with a 1017mb ridge across the Gulf coast. The stalled front had no precipitation along it in our region and is expected to drift back north north today as ridging surface and aloft begin to strengthen over our CWA from the south. This will lead to another warmer than normal day with afternoon temperatures topping out 95- 98F. Ridging surface and aloft along the Gulf coast from the east will remain dominant over our CWA Sunday.
Where it's been raining, temperatures are a bit cooler in the mid to upper 60s. Low temperatures tonight will be a touch warmer than the upper 30s to mid 40s the CWA felt last night, as return flow southeasterly winds and partial cloud cover help hold temperatures up, generally in the upper 40s to mid 50s throughout the region.
This chance of rain and storms is expected through the day across the area as the upper trough moves over the Oklahoma and Texas panhandles. The lift from the upper trough will move eastward on Sunday so rain chances will be primarily across the eastern CWA. Weak upper ridging will remain across the region with troughs passing over the northern conus.
628 AM EDT SAT JUL 2 2016 Cooler and drier weather is expected today with highs mostly in the 70s.
High pressure with mid level ridging will keep hold on the western Lake superior region through Sunday. Tonight's lows will dip into the low 40s as clear skies and calm winds promote another night of radiational cooling. The nice weather will continue into the holiday as the ridge continues to dominate the weather across the region.
442 AM EDT SAT JUL 2 2016 as expansive high pressure over the Upper Mississippi Valley will gradually build across the Ohio Valley. A large area of high pressure centered over the Mid Western states will expand across the Lower Great Lakes today. mainly clear skies with lows dipping into the lower to mid 50s. A slow moving upper low over Quebec and ridging over the Northern Plains states will yield a confluent flow over the Lower Great Lakes region through the remainder of the extended Independence Day Holiday weekend. While temperatures will average near normal Sunday, slight warming aloft will lead to highs on Independence Day in the lower to mid 80s.
These clouds are associated with an upper level trough moving into British Columbia and the Pacific northwest over the weekend. Not much change for Sunday as the trough continues to bring westerly flow aloft over the region.
This was associated with an elevated warm front and associated low pressure in eastern Montana. The high pressure slides SE with time, settling into far srn lower Michigan.
422 AM EDT SAT JUL 2 2016 Cooler and drier weather is expected today with highs mostly in the 70s.
High pressure aloft will give way to a more zonal on shore flow through the weekend.
153 AM EDT SAT JUL 2 2016 A pressure ridge will extend from the Atlantic westward into the Gulf of Mexico through Independence Day. A weak pressure trough will linger in the forecast area. Overnight lows will be in the lower 70s. The models displayed surface ridging extending from the Atlantic westward into the Gulf of Mexico. North of the ridge a frontal zone was shown remaining north of the forecast area with weak lee- side troughing in the area. Expect thunderstorms mainly associated with heating and convergence into the trough or into a possible seabreeze front that may move well inland. Leaned toward the higher high temperature guidance because of the recent bias. The GFS and ECMWF displayed surface ridging extending from the Atlantic westward into the Gulf of Mexico through the medium-range period.
412 AM EDT SAT JUL 2 2016 High pressure will be over the area today and will slide east of the area tonight.
Temperatures over the weekend will climb well into the 90s with today likely being a touch hotter than Sunday as high pressure continues to dominate the weather in the region. Rain chances are on the low side but a stray shower or thunderstorm is at least possible, more likely on Sunday to at least give a temporary reprieve from the heat. Heat index values in the lower triple digits are likely on both Saturday and Sunday. Seasonal bermuda ridge pattern becoming established to persist for the duration of this forecast package, with generally light winds and low seas.
Deep monsoonal moisture will remain over the region Saturday as the associated positive tilted trough continues to make its way across Utah and Colorado. The general flow will change from southerly to northwesterly on Saturday as the trough passes through which will change the areas which receive enhanced rainfall and allow drier air to filter in. Forecast soundings do indicate slower storm motion as the trough passes and winds change direction so something else to consider. On Sunday, high pressure will attempt a return.
134 AM EDT SAT JUL 2 2016 High pressure will build southeast across the region tonight and then persist into Sunday.
Breezy, warmer and generally drier conditions return Sunday as the upper ridge axis moves over the CWA.
343 AM CDT SAT JUL 2 2016 The weak cold front that moved through the Mid State yesterday with isolated showers and storms was located from the Appalachians down into central AL/GA this morning. Dry high pressure will be the main feature today. A trough will be moving from the plains into the Mid Ms Valley region as a warm front sets up just to our north. As highs Sunday climb into the low to mid 90s, heat index values will touch 100 in some areas.
454 AM EDT SAT JUL 2 2016 Weak summertime flow pattern will continue with a weak short wave passing through the area early in the weak followed by increased ridging. At 230 PM Saturday: An upper trough will deamplify over the eastern seaboard today, resulting in zonal flow from the mid MS River Valley to the NC coast that will persist through tonight. At the surface, a slow moving cold front will stall over our area today, somewhere in the vicinity of the NC and SC border, remaining there through tonight. Temperatures will run slightly above normal as the upper ridge flattens.
639 AM EDT SAT JUL 2 2016 High pressure will be over the area today and will slide east of the area tonight.
312 AM PDT SAT JUL 2 2016 A weak trough of low pressure near the California coast today will bring drying of mid level monsoonal moisture and deepening of the marine layer with coastal low clouds and patchy fog extending into the far inland valleys.
412 AM CDT SAT JUL 2 2016 Thunderstorm development expected to be enhanced today and tonight with the approach of a short wave trof and the arrival of its associated cold front. Cold front makes its way through most of the forecast area tonight, and then passes through the southeast Texas Panhandle Sunday morning.
404 AM EDT Sat Jul 2 2016 A cold front will continue to push southeast from the area this morning. High pressure will build in from the west through tonight. A warm front will lift into the area Sunday into Sunday night.
423 AM EDT SAT JUL 2 2016 Skies are mostly clear with temperatures ranging from the upper 70s to the lower to mid 80s along the island chain. Surface wise, a narrow ridge is draped across extreme South Florida resulting in east to southeast winds of 10 knots or less on our coastal waters.
Will also need to watch a developing weak trough axis across west Texas and the Big Bend that could lead to a few showers near Val Verde this afternoon as well. By Sunday, the weak trough axis will pass across north-central Texas as agreed upon by global and hi-res models. GFS model perturbations show more clustering around a stronger H5 ridge solution over west Texas and more progressive weak trough. With a stronger ridge potentially in place and the current trends in observed temperatures, slight tweaks of 1-2F degrees upward were made to model guidance high temperatures for select locations.
We expect less cloud cover into tonight and a little warmer as the ridge retreats further to the east and a southerly wind becomes more established.
331 AM MDT SAT JUL 2 2016 A weak upper trough will begin to pull away from the area today. By Sunday an upper high will strengthen over the Borderland with even less thunderstorm activity and afternoon temperatures returning to the triple digits in the lowlands by Independence Day. Then the upper high will shift eastward somewhat after midweek with thunderstorm chances increasing again. The upper trough partially responsible will move across the area today with drier air filling in behind it. By Sunday an upper high will strengthen and position itself over the Borderland for a few days, which will stabilize the atmosphere somewhat and keep thunderstorm development mainly over the mountains.
