321 AM CDT Mon Jun 5 2017 Cold front still north of FA, with water vapor imagery showing upper Low circulation center over Texas, with super saturated advection of deep seeded moisture wide open from the Gulf northward and across the mid Mississippi river valley. Model soundings show best/deepest isentropic upglide/moist advection this morning, with a drop-off thereafter, even though diurnally destabilizing atmosphere means storm chance will continue til cold front makes passage there this evening/overnight. We'll let Pops ride thru the front's passage during the evening, then drop them into silent range after fropa overnight, as the by then south Texas Low is pinched off by the Ohio river valley vort and cold front's passage.
This will prevail until the mid level trough pushes across the state closer to the end of the week.
243 AM EDT Mon Jun 5 2017 Periodic shower and thunderstorm chances are expected for the first half of the week as upper low pressure settles over the region. The short term period will feature the further digging of a very cold upper low over the Eastern CONUS with the latest solutions indicating the cutoff center over the NY/PA border by Tuesday.
Overall, a benign weather day is in store with temperatures ramping up this afternoon reaching into the high 80s to even low 90s. Relatively light northwest winds will shift from the northeast as a backdoor cool front moves across the area today and into the evening with high pressure beginning to build in. Cooler dewpoints accompany this boundary passage which will help to keep conditions more pleasant and less humid. As for temperatures tonight, mostly clear skies will aid radiational cooling and lows in the low 60s can be expected.
428 AM CDT Mon Jun 5 2017 The small convective cluster in Navarro County developed underneath the core of our upper trough. This cP air will not be extraordinarily cool, but the lower humidity will make for some pleasant mornings.
WV/IR trends show an upper trough lifting into MT this morning, and much of the forcing with it. Models are advertising a warm and dry week as ridging builds back into the area.
638 AM EDT Mon Jun 5 2017 A low pressure system slowly drags a cold front through Monday night.
327 AM CDT Mon Jun 5 2017 One more day to deal with the upper low and its associated showers and thunderstorms before the low shifts southeast of the area.
Deterministic NAM/ECMWF/GFS predictions generally agree with the position/timing of the upper low during the period. The upper low is predicted to move slowly EWD during the period with associated subsidence increasing over the WRN CWA this afternoon then areawide Tonight/Tuesday. Expect the combination of the upper low/moisture to contribute to scattered convection Today confined mainly to the ERN CWA/MSA (increasing subsidence WRN CWA. ) As the upper low moves east Tonight/Tuesday, a weak frontal boundary is expected to move across the CWA/MSA.
Upper low continues to shift east of the area with precipitable water values near 1. Surface pattern remains weak with a weak trough/front across central portions of Nebraska and Iowa with an isolated convection here too. Models are in good agreement in the large scale with the upper low slowly shifting southeast tonight, with mid and upper level drying and subsidence moving in. Somewhat elevated freezing levels and slow motions allowing for some heavier amounts to fall and will need to keep an eye on any training. Good insolation and somewhat warmer air working into for Monday brings and warm and dry day, with some temps likely reaching 90.
With moderate southeast breezes and under mostly cloudy skies, temperatures in the Florida Keys are in the lower 80s.
649 AM EDT Mon Jun 5 2017 The air mass across the region today and tonight will be moist and unstable ahead of a slow moving cold front.
345 AM EDT Mon Jun 5 2017 Low pressure over the eastern Great Lakes will move southeast today. pushing a slow moving cold front across the local area by tonight.
A cold front is expected to pass through the area today. In the wake of this front, high pressure is expected to move into the area for most of this upcoming week. Otherwise, cold front dropping through the southern Great Lakes is expected to move into the far northwest zones by the late morning hours, passing south of the forecast area by early evening. Model data suggest a deep upper trough will evolve over the eastern parts of the country during this period.
A moist tropical airmass will continue to lift northward across the region ahead of an potent upper level trough over east Texas moving into the far western Gulf by this afternoon.
300 AM EDT Mon Jun 5 2017 Below normal temperatures over the next several days as the cold core upper level low (-24 C at 500 MB) currently just southwest of James Bay tracks through Lake Huron today, and into the Eastern Great lakes tonight/tomorrow. Heart of the cool air in the low levels in place on Tuesday, as 925 mb temps hold in the upper single numbers, and should be looking at highs holding in the 60s, with northern thumb region holding in the upper 50s.
346 AM EDT Mon Jun 5 2017 Aviation section updated A cold front is expected to pass through the area today. In the wake of this front, high pressure is expected to move into the area for most of this upcoming week. Otherwise, cold front dropping through the southern Great Lakes is expected to move into the far northwest zones by the late morning hours, passing south of the forecast area by early evening. Model data suggest a deep upper trough will evolve over the eastern parts of the country during this period.
The HRRR/NCAR Ensembles show scattered storms developing in the convergence along this trough between 18-20Z, and then slowly moving eastward toward the WY-NE border. A cold front will slide southward over the CWA through the evening/night. Highs on Tuesday will be a good 10-15 degrees cooler.
A cold front will move through the area, bringing chances for showers and thunderstorms tonight into early Monday. Then high pressure will bring cool and dry conditions mid week.
406 AM EDT Mon Jun 5 2017 An upper low over the ArkLaTex region in conjunction with an additional system pushing southward through the Great Lakes continues to put our region squarely under a moist southwest flow aloft. Additionally, a cold front will begin to push into north Georgia tonight which will concentrate further shower and thunderstorm development. Temperatures today will be limited to the lower to mid 80s for most areas, while many locations will struggle to reach 80 degrees on Tuesday. RW The upper trough that has been sitting over the lower Mississippi Valley will fill as an upper low drops out of southeast Canada and moves into Pennsylvania. This will pick up the weakening low over the lower Mississippi Valley and and move it rapidly out of the CWA.
234 AM EDT Mon Jun 5 2017 A slow moving upper low will bring several days of unsettled weather to the region with cooler temperatures poised to settle in through at least midweek. Based on recent HRRR runs and radar trends, will hit Warren/Mckean counties with the highest (categorical) POPs between 03Z-06Z. The upper pattern will feature a deepening upper trough that is destined to close off over the NERN and dominate the weather for much of the upcoming week. Highs generally in the 70s will be several degrees cooler than average.
242 AM CDT Mon Jun 5 2017 A stable post-frontal regime is anticipated across the area today as the slow moving mid/upper trough shears eastward away from the area. Both take the mid/upper ridge across the Rockies and translate it eastward through the weekend. Other than some diurnally driven storms drifting eastward off the high plains late in the week, we expect to see rising temperatures and mostly dry conditions by the weekend. Highs may climb into the lower 90s with lows in the low 70s. Strong and severe storms will likely accompany this trough as it moves across the central CONUS in the Mon-Tue timeframe as deep layer shear becomes more favorable.
354 AM EDT Mon Jun 5 2017 The air mass across the region today and tonight will be moist and unstable ahead of a slow moving cold front.
A cold front will push into the area from the north later this afternoon, with lower dewpoints filtering into the area from the northeast.
The upper level low that had been parked over Texas and Oklahoma this past weekend which brought widely scattered showers and thunderstorms to the area, will get absorbed in the upper level flow today. Meanwhile, a upper level trough will deepen and dig through the Great Lakes today. This will drop a back door cold front through the area later in the day.
In the meantime, a sharp trough was still dipping to the southeast today. At the same time, highly amplified upper level ridging will build on the High Plains. Storms will likely initiate on the higher terrain of New Mexico and eastern Colorado this afternoon under broad east-southeasterly low level flow.
1229 AM CDT Mon Jun 5 2017 A band of showers and thunderstorms has developed near the I-70 corridor this afternoon in response to a weak vorticity lobe to the north of a closed low over Oklahoma. The closed low to the south will accelerate southeastward tonight and Monday and allow height rises to build in from the west.
After a relative midday lull, the surface cold front associated with the closed low over the Great Lakes will drop south into the region during the mid/late afternoon. With highs reaching the lower 80s, CAPE cranks up near 2000 J/kg and downdraft CAPE over 700, which would support at least a few pulse storms with marginal severe wind gusts possible. Otherwise cooler and drier air spills in for the balance of tonight and Tuesday, with below normal temps and decreasing humidity.
251 AM EDT Mon Jun 5 2017 Low pressure over the eastern Great Lakes will move southeast today. pushing a slow moving cold front across the local area by tonight.
As it continues to wobble to the southeast, the tropical airmass will remain locked in with the highest PW axis focused over western sections.
The 500mb ridge will continue to build overhead through this evening, before becoming surpressed as a trough swings across south central Canada and ND.
209 AM PDT Mon Jun 5 2017 Dry and warmer weather will linger through the first half of the work week, followed by more unsettled and much cooler weather by the end of the week.
207 AM EDT Mon Jun 5 2017 Moisture will increase in the southerly flow between high pressure off the coast and a cold front approaching from the northwest.
Winds over northern IL show that cooler, drier airmass is on tap for the region. 19z/2pm surface analysis shows weak cold front extending from southern Lake Michigan to southern Iowa. Once the front drops into the Ohio River Valley, a cooler/drier airmass will arrive on Monday. High temperatures will drop into the lower to middle 80s, while dewpoints slip into the 50s. Pronounced upper trough over eastern Canada into the northeast U.
358 AM EDT Mon Jun 5 2017 Low pressure across eastern Lake Erie will take a cold front south across the area today. A trough will linger across the eastern Great Lakes though as an upper low remains nearly stationary through mid week.
An upper level trough will continue to gradually swing east out of the Southern Plains and into the Lower Mississippi River Valley over the next twenty-four hours. While there will be some decrease in convection this evening and overnight, good rain chances will remain across the forecast area tonight, as a cold front associated with the aforementioned upper trough, begins to sink south into the forecast area. High rainfall rates from torrential downpours, as a result of the very moist airmass entrenched over CWA with dew points in the lower 70s and precipitable H2O values around 2 inches, could also result in some localized flash flooding.
/00Z Update/ Scattered convection continues across the region moving E/SE around the western side of the upper level low. The storms should wane this evening with the loss of diurnal heating, but like last night, the Low Level Jet might support isolated storms around throughout the night.
529 AM EDT Mon Jun 5 2017 Periodic shower and thunderstorm chances are expected for the first half of the week as upper low pressure settles over the region. The short term period will feature the further digging of a very cold upper low over the Eastern CONUS with the latest solutions indicating the cutoff center over the NY/PA border by Tuesday.
The main weather concern will be the heat as high pressure aloft continues to strengthen over the region.
359 AM CDT Mon Jun 5 2017 The upper low that brought beneficial rains to the area over the past few days will continue to slide southeast toward the Gulf of Mexico. Meanwhile, an upper ridge has been building to our west and northerly flow has developed aloft in between the two systems. Today looks fairly dry given subsidence on the backside of the upper low, but a few storms could make their way into western portions of the area off the higher terrain of NM.
Weak high pressure extended from the western Great Lakes into the lower Missouri Valley at 07Z with mainly clear skies across the region this morning. More expansive high cloud cover was located to the south from southeast Kansas across much of Missouri in association with rather broad cut off upper low over the southern plains. High pressure will dominate the forecast area today with a warm front developing from the western Dakotas into central Nebraska during the afternoon in advance of low pressure moving across southern Saskatchewan. A cold front extending from the low will move into the western Dakotas and far western Nebraska tonight with scattered thunderstorms in the vicinity of the front.
238 AM EDT Mon Jun 5 2017 A low pressure system slowly drags a cold front through Monday night.
/Today through Tonight/ Large area of high pressure centered near Hudson Bay with ridging extending well south into the Northern Plains and Great Lakes regions, will continue to settle south today. This will result in a cold front moving into Iowa from the northwest with modest cold advection during the day.
A northeast-southwest oriented trough axis aloft, basically the remnants of the upper low that brought the weekend rains, resides over NW AR down into SE OK early this morning. The bulk of the precip coverage this morning lies east of the trough axis and east of the forecast area toward central AR. The trough axis will slide slowly south thru the day today due to increasing northerly flow aloft over the Plains. The latest hi-res data suggests that precip coverage will be more diurnally driven today compared to previous days on the northern limb of the upper trough, and thus PoPs will start off low this morning and increase to scattered for the afternoon hours across W Central AR down into SE OK. PoPs should end quickly after 00Z with the trough sliding farther away and daytime heating ceases.
655 AM EDT Mon Jun 5 2017 A cold front dropping south across Ohio will be the focus for scattered showers and thunderstorms today.
437 AM EST Sat Nov 25 2017 A cold front will move across the region today.
At the surface, a 986mb low was located just sw of James Bay with a cold front extending into nw WI. Otherwise, temps will drop closer to seasonal averages with highs in the lower to mid 30s. Nam has a 500 mb ridge across the Rockies which moves into upper Great Lakes on Mon. A trough then moves into the northern Rockies 00z Tue and into the northern plains 12z Tue.
216 AM EST Sat Nov 25 2017 A cold front is working its way through central Wisconsin at this hour. Latest surface analysis has cold front near the IL/IN border and will be moving across the forecast area this morning. Surface ridging will build in from the west tonight bringing clearing skies.
1222 AM EST Sat Nov 25 2017 High clouds begin to move in tonight with ceilings lowering during the day on Saturday ahead of a cold front.
346 AM EST Sat Nov 25 2017 A weak cold front will move through the Ohio Valley this morning offering only a slight chance of a shower or sprinkle. High pressure will build in behind the front, persisting into the middle of the work week, offering continued dry weather. Expect a brief decrease in clouds with the frontal passage and then an increase in low level clouds as mid level post frontal trof settles into the area late this morning into this aftn. Mid level trof axis to pivot east of the region with northwest flow developing. Expect temperatures to be near normal with lows from the upper 20s north to the lower 30s south.
A cold front has moved through the CWA and now resides near the MO/AR border.
211 AM CST Sat Nov 25 2017 A cold front at 2 AM had crossed south of the Plateau and will continue to move through the remainder of the forecast area by sunrise. No rainfall is expected to reach the ground due to the dry air in the lower levels of the atmosphere. Temperatures will be noticeably cooler today as highs struggle to reach seasonably cool normals compared against yesterdays record high readings.
205 AM MST Sat Nov 25 2017 A cold front is currently moving across the area early this afternoon with north winds gusting 30 to 40 mph.
232 AM EST Sat Nov 25 2017 An approaching dry cold front will move through the forecast area this evening.
/Issued 623 PM EST Fri Nov 24 2017/ An upper level trough will drag a cold front through the state Saturday.
114 AM MST Sat Nov 25 2017 Except for some patchy morning fog in the far west valleys and basins, today will feature partly sunny weather along with some high clouds as a ridge tries to build in from the west. Temperatures today will be a bit cooler behind yesterdays front.
128 AM EST Sat Nov 25 2017 A cold front will move into Northwest PA by morning and sweep southeast across the state Saturday with just scattered brief light rain showers as it passes.
Some very light radar returns are showing up with pretty high cloud bases, the lowest seen on observations is around 9000ft and only one station reporting any rain. Given the cloud cover, highs today will be slightly cooler than yesterday, in the lower 60s.
312 AM EST Sat Nov 25 2017 A cold front approaches from the Ohio Valley today, then crosses the area tonight.
305 AM EST Sat Nov 25 2017 Shower chances return today with the passage of a cold front.
Northerly winds of 10-15 mph will occur behind the front, but we won't see noticeably cooler air ushering across the region.
Northwest winds will remain gusty overnight tonight as cooler post frontal air builds into the area. Northwest winds will continue to gust behind the cold front that passed through the area earlier this evening. The cold front is just about through southeast WI. Cold front is moving through the nearshore waters. Medium to High Cold front combined with mid level energy may set off a few showers across southern WI later this evening. Otherwise cold advection kicks in later tonight and this will persist into Saturday with low level thermal trough in place. So potential for more cloud cover along with significantly cooler temps.
1003 PM MST Fri Nov 24 2017 Current surface map show cold front well south of the forecast area. High pressure builds across the area for tonight and Saturday with mostly clear/sunny skies and light winds.
327 AM CST Sat Nov 25 2017 The cold front that moved into the forecast area yesterday has exited to the southeast, with northerly winds in place behind the front as surface ridging builds into the area. The region will remain under northwesterly flow aloft as the mid-level trough advances into the eastern U. with a mid-level ridge building in across the western U. These light northerly winds combined with mostly sunny skies will result in "cooler" conditions today (compared to yesterday's record- breaking temperatures) with highs in the low 60s, which is still 10F- 15F degrees above the seasonal normals.
While much cooler than yesterday, this is still well above normal for the season.
305 AM EST Sat Nov 25 2017 A cold front will approach from the west today and will cross the region tonight.
803 PM PST Fri Nov 24 2017 Cooler weather will gradually build from the coast to inland areas through the weekend.
236 AM EST Sat Nov 25 2017 A cold front crosses today with limited moisture.
Cold front currently in the Texas Panhandle will move south through terminals by shortly after 25/12z.
211 AM CST Sat Nov 25 2017 A cold front was moving through the forecast area at 07Z/1am, and was located from Grand Marais to Staples. These sprinkles or flurries are very short lived as dry air is moving into the region behind the cold front and leading to a gradually clearing sky. Elsewhere, high pressure will be arriving. The high pressure will remain over the region through tonight.
312 AM CST Sat Nov 25 2017 At 09Z a cold front is rapidly approaching the forecast area.
Temperatures after midnight, were in the lower 70s with dew points in the lower 60s. As a cold front continues to move south and away from the Florida Keys, drier air will stay over the Keys today, keeping rain chances close to nil.
344 AM CST Sat Nov 25 2017 The overall upper level pattern currently is slight troughing to the east and similar ridging to the west with an area of high pressure over the Baja Peninsula.
1125 PM CST Fri Nov 24 2017 Temperatures have soared in central Kansas this afternoon, and wind speeds have increased greater than anticipated behind the cold front across central Kansas. After record setting warmth this afternoon, temperatures will remain unseasonably mild over the weekend as the air behind the cold frontal passage tonight will be of modified Pacific origin.
304 AM CST Sat Nov 25 2017 A cold front will drop south through the region today in the wake of an upper trough traversing the Midwest U.
1005 PM MST Fri Nov 24 2017 West flow aloft with weak ridging over the western U.
251 AM EST Sat Nov 25 2017 A rather weak cold front will move across the area this afternoon and evening with an associated upper level trough and decent mid-high level moisture only and no instability at all.
The region remains in dry northwesterly flow aloft and southwesterly flow developing at the surface as high pressure slides off to the east.
334 AM CST Sat Nov 25 2017 At 2 AM, high pressure was located over northern Florida and a weak cold front extended from the southern Great Lakes into the Texas panhandle. A warmer start to the day coupled with weak warm air advection should yield warmer daytime high temperatures.
100 AM EST Sat Nov 25 2017 A weak cold front will move through the Ohio Valley this morning offering only a slight chance of a shower or sprinkle. High pressure will build in behind the front, persisting into the middle of the work week, offering continued dry weather. The surface cold front will clear the forecast area later Saturday morning with cooler air slowly working into the area.
1212 AM EST Sat Nov 25 2017 Shower chances return today with the passage of a cold front.
Surface winds will be South less than 6 knots becoming light and variable to light Southwest late prior to the arrival of a cold front.
Breezy southwest winds will diminish this evening as a cold front approaches from the northwest. With the lower layers of the atmosphere remaining dry, only expect mid and high level clouds to accompany the front through the area. Temperatures will be some 10 degrees cooler on Saturday, but still remaining above normal for late November with highs in the upper 50s to lower 60s.
Temps will be a bit cooler today, but still much above normal for this time of year.
419 AM EST Sat Nov 25 2017 High pressure just to the south will weaken today as offshore low pressure passes well to the southeast.
