1234 AM EST Mon Nov 6 2017 Temperatures will continue to fall overnight as high pressure builds into the western Great Lakes. High pressure will build in for most of this week but temperatures will be cool with highs mainly in the 40s and lows in the upper 20s to lower 30s. Otherwise, the cold front will continue to dive quickly to the east- southeast.
1150 PM CST Sun Nov 5 2017 /06Z TAFs/ The cold front continues to push southward through the Metroplex as of 05z, and should clear all the TAF sites in the area before stalling south of Interstate 20 before 09z. The cold front has reached a Possum Kingdom-Argyle- McKinney-Paris line as of 915 pm, and this convergence zone is pretty well defined on KFWS reflectivity. and with the airmass immediately north of the front likely to remain quite shallow and easily mixable, I didn't adjust the highs downward for the Metroplex area at this time. However, I did go ahead and lower the highs just a bit along the northernmost tier of counties, where modest cold air advection should continue.
That comes courtesy of broad low level ridging and increasingly anticyclonic flow working through the region, with that feature expected to slowly cross the area today, bringing with it a notably cooler and much drier airmass.
Temperatures tonight will fall to near or below freezing.
443 AM EST Mon Nov 6 2017 A cold front will continue to work through the region this morning.
345 AM EST Mon Nov 6 2017 A cold front crosses today.
Confidence is higher for the low clouds to make it to CDS than to PVW. /issued 808 PM CST Sun Nov 5 2017/ Have updated the grids to account for a faster cold front movement and the increasing potential for post-frontal stratus moving into the northeast and north-central zones later tonight. /issued 530 PM CST Sun Nov 5 2017/ Cold front has made it to CDS with winds shifting to the northeast. Models are still on track for a backdoor cold front to move through the area late this evening into Monday. This will leave all areas, except the far NE portions of the CWA, warmer than normal for one more day.
/issued 750 PM EST Sun Nov 5 2017/ Upper to surface ridging over the region keeping mild fall conditions over the area.
Low pressure was developing across Wyoming this evening and will move east through portions of the Dakotas on Monday.
A weak cold front will get close to KMAF, but will lift north by morning.
1142 PM CST Sun Nov 5 2017 A cold front will make its way across the Missouri Ozarks through early this evening. The front will clear the area by late evening ushering in a noticeably cooler airmass. A much cooler and more typical autumn day is in store for Monday.
1125 PM CST Sun Nov 5 2017 132 PM CST High pressure will continue to build into the region as storm system moves east. The expected BKN-OVC conditions should prevent temps from falling to far tonight and will also keep temps a bit cooler tomorrow as cloudiness is likely to linger. By late in the week, medium range models have been trending toward a more amplified solution with a progress, but still deep trough digging into the Great Lakes region.
241 AM MST Mon Nov 6 2017 Current surface shows high pressure across northern Montana into the eastern Dakotas. For today, positive tilt upper trof drops through the northern plains with reinforcing shot of cold air. Upper trof shifts south of the area tonight with snow ending.
322 AM CST Mon Nov 6 2017 Satellite and upper air data showing zonal flow in place across the central CONUS early this morning, high pressures remains over Mexico, while broad troughing slides through eastern Canada and another disturbance is moving through the Pac NW. At the surface, winds remain northeasterly and light, as high pressure sits centered over far northeastern NE up through the eastern Dakotas. Winds through the day are expected to be east- southeasterly, elongated high pressure remains off to our north, while low pressure is deepening over eastern CO.
350 AM EST Mon Nov 6 2017 Temperatures will continue to fall overnight as high pressure builds into the western Great Lakes. High pressure will build in for most of this week but temperatures will be cool with highs mainly in the 40s and lows in the upper 20s to lower 30s. Overall, the ECMWF has had the best handle on the low level thermal fields associated with this developing airmass the past several days and is the preferred model of choice for this package.
244 AM CST Mon Nov 6 2017 08Z water vapor imagery showed an upper trough moving into the northern Rockies and a second upper trough moving through the New England states. At the surface, high pressure centered over the northern plains stretched into northern OK. Dry air in the lower atmosphere makes it unlikely these radar returns will amount to much of anything. For today and tonight, models are in agreement that zonal flow aloft will continue while high pressure at the surface remains over the area. However the model progs do not seem to have as strong a push to the high pressure as current 850MB profiler data suggests, still showing north wind into southwest MO. Models bring a reinforcing push of high pressure into the state tonight.
225 AM EST Mon Nov 6 2017 A cold front will push southeast across the area today. A ridge of high pressure will then build into the region from the Great Lakes for the middle of the upcoming week. Regional radar loop at 07Z showing a weakening line of showers working through central Pa in advance of a cold front, which at 07Z is just entering northwest Pa. Temps will likely fall to the upper 40s over Warren Co, as the cold front pushes through around dawn. Surface cold front pushes southeast through the forecast area this morning into early afternoon, exiting Lancaster Co by 20Z based on latest guidance.
/Issued 957 PM CST Sun Nov 5 2017/ Cold front has pushed through the entire area.
Like yesterday, temperatures this morning are mainly in the lower 70s, some 15+ degrees above climatological normals. For the remainder of today, whatever fog develops expected to lift right after sunrise as the winds mix the boundary layer, leaving partly to mostly cloudy skies with afternoon temperatures in the lower to mid 80s, about 8-10 degrees above climatological normals.
327 AM CST Mon Nov 6 2017 High pressure ridge over the Missouri River Valley in the Upper Midwest this morning building into the region. Rest of the week remains far cooler than recently, and slightly cooler than normal.
130 AM EST Mon Nov 6 2017 Low pressure will ripple along a cold front as they push southeast across the region tonight. Clouds and a few lingering showers are expected on Monday along with cooler temperatures.
311 AM CST Mon Nov 6 2017 At 300 AM CST, a weakening cold front was moving across Mid TN, approaching the Nashville area, with showers and scattered thunderstorms along and ahead of it. Showers and thunderstorms will spread across the entire area tonight as a disturbance moves in from the west, generating a low pressure wave along the stalled front.
320 AM CST Mon Nov 6 2017 A cooler air mass has moved over the area behind the front that passed through the region on Sunday. Highs will warm into the upper 40s to the lower 50s this afternoon, which will be 20 to 30 degrees cooler than the highs that occurred on Sunday. Lows tonight will drop into the upper 30s to the lower 40s. Cooler conditions will occur across the area through much of this week.
1231 AM EST Mon Nov 6 2017 Weak high pressure will hold over the region through today.
825 PM PST Sun Nov 5 2017 A weak trough may bring patchy light rain or sprinkles along and west of the mountains at times from late tonight through Monday night.
222 AM MST Mon Nov 6 2017 The region will remain situated between strong high pressure centered over Mexico and strong low pressure well to the north.
352 AM CST Mon Nov 6 2017 (Today and Tonight) A weak cold front along the I-20 corridor has pushed south of Sweetwater to Abilene at 3 AM. This front will likely get hung up into the hills south of Sweetwater and Abilene, and keep the Big Country cooler today in the 70s, with mid and upper 80s to the south. Given the front, went closer to GFS MOS temperatures today in the Big Country versus some the warmer consensus models.
352 AM CST Mon Nov 6 2017 A broad upper high pressure ridge centered over Mexico remains in control of our weather.
1135 PM CST Sun Nov 5 2017 The cold front will continue through north and central Arkansas overnight.
1129 PM CST Sun Nov 5 2017 Cold front has pushed well into OK at this time, with lots of post frontal low clouds, and copious amounts of low level moisture. Expect to see cooler than normal temps continue for the beginning of the week, with very little chance in the low cloud cover dissipating anytime soon, even as a ridge of high pressure moves across the northern plains. Ketcham The cooler than normal temp trend will continue for most of the mid week. Cold front is situated well south of the forecast area as it is now south of the Red River.
Once stratus erodes in the following hours, cool surface ridging lingering off the Caprock will remain largely unchanged and serve as a barrier to milder westerlies across the western South Plains. This should limit the wavy surface front's eastward progress and make for some challenging high temps, but the overarching theme from short term models is for cooler highs today over roughly all but our western 1/3 of counties. Stratus should re-emerge slowly late tonight, initially in the eastern Panhandle behind a robust cold front before expanding south through the South Plains Tue morning.
1118 PM CST Sun Nov 5 2017 Low stratus from this morning continues to push south and away from the local area as the responsible cold front is now entering the southern plains.
Cold front at 2 pm was located roughly from the north side of St. The current front will make it into the Tennessee Valley, before a low pressure rides along it.
Blended guidance also supports this for the most part, although may be overdone around Mobridge/Aberdeen.
Latest regional mosaic radar imagery shows a line of showers and thunderstorms has formed along the cold front to our northwest, and currently stretches from west of Poplar Bluff, Missouri northeastward to just northwest of Evansville, Indiana. As advertised the thunderstorms out a head of the cold front are knocking on the door at 06Z.
An area of high pressure will cross the region tonight through early Monday morning. On the back side of the high, southerly flow should develop fairly quickly, especially over western SD.
The polar front jet remains to our north where the cold front remains while the subtropical jet is over our CWA. More snow is expected as temperatures in that region are hovering around freezing and cross sections show more available moisture.
320 AM EST Mon Nov 6 2017 A cold front will move across the region today.
1004 PM MST Sun Nov 5 2017 Latest upper level analysis has an upper trough over the western CONUS creating west southwest flow across the Northern High Plains. At the surface, high pressure is centered over the Dakotas.
327 AM CST Mon Nov 6 2017 The cold front has cleared the entire area and pushed all of the convection southeast of the area. North winds area pushing much cooler air into the region, and with no sunshine expected today, little warming is expected.
346 AM EST Mon Nov 6 2017 Low stratus clouds currently blanket Michigan early this morning behind the cold front which has now cleared well south of the state. The more westerly flow aloft will prevent a greater push of even colder air into the region and keep temperatures in the lower/mid 40s towards the Tri-Cites and Thumb and mid/upper 40s towards metro Detroit.
327 AM CST Mon Nov 6 2017 A cold front continues to move through the Mid-South this morning. An area of low pressure will develop along the front near Northeast Texas and move east. Rain associated with the low will begin to spread into Northeast Arkansas around noon and will continue to move east affecting areas along and north of I-40 during the afternoon hours. The low will push into South Central Kentucky by sunrise allowing the cold front to begin pushing back to the south.
Quiet conditions will prevail tonight, light wind and mild temperatures dominate under high pressure. High temperatures will remain in the low to mid 80s through mid-week and low's in the mid 60s to the 70s along the east coast metro areas. weak short wave over the central plains will make its way east weakening the ridge across the Gulf by the end of the week. This weak trough will bring a surface disturbance over the region allowing for a better chance of showers by the end of the week. However, the Miami Beach police did not report any coastal flooding during the high tide this morning which was at 3.
341 AM EST Mon Nov 6 2017 North and central GA will remain under a flat ridge aloft through the short term.
401 AM EST Mon Nov 6 2017 Under mostly clear skies and light north winds, temperatures are averaging in the lower 70s along the Florida Keys. Surface wise, a lengthy ridge axis extends across extreme north Florida and the adjacent Atlantic and Gulf waters. High temperatures will average in the lower to mid 80s with overnight lows in the lower to mid 70s. The aforementioned ridge (2nd paragraph) will likely be reinforced by a massive and very formidable anticyclone centered over the northeast United States. This expansive ridge axis will bridge over a decaying cold front draped over the Florida peninsula. With that said, a freshening but predominate Atlantic trajectory will maintain slightly above normal temperatures with highs in the lower 80s and overnight lows in the lower to mid 70s.
Rainfall intensity will decrease overnight as cold front swings through the area. Pre-frontal trough will finally exit the region shortly before dawn, which will allow the cold front to pick up speed toward the southeast. Again, the highest Pops will be exiting the region with the front, but will still need to keep in at least a chance of showers behind the front, until the last wave of energy exits by afternoon. Clouds will slowly decrease from the northwest as cooler and drier air moves southward.
At the surface, a ridge of high pressure will extend from the nrn Great Plains to central WI.
1133 PM CST Sun Nov 5 2017 20Z surface analysis shows a cold front has moved across the forecast area and into central WI.
Quiet again across the high plains tonight, with scattered cirrus drifting by in the increasingly SW flow aloft. Temperatures will easily hold in the 20s through sunrise, and will hold above freezing across the SE zones. SW flow aloft strengthens quickly, in response to a 546 dm closed low approaching the Grand Canyon by 6 pm. There will be a considerable temperature gradient this afternoon, ranging from the mid 50s far east to the lower 70s far SW. As the surface cyclone in SE Colorado remains nearly stationary, surface winds will maintain a SE to NE (easterly) component.
Warmer again today with highs climbing into the 70s for most locations. as south winds ahead of the upper level low increase.
1112 PM CST Fri Jan 19 2018 Updated aviation section for 06z taf issuance Mostly sunny early this afternoon and finally above freezing area wide.
345 AM EST Sat Jan 20 2018 A narrow upper ridge axis extends northeast from Mexico toward the Bluegrass State early this morning. At the surface, weak low pressure was located near the CO/NE border, with high pressure lingering over the Southeast.
254 AM EST Sat Jan 20 2018 High pressure will prevail this weekend.
Weak upper level ridging and confluent flow will keep things quiet across the forecast area today. Temperatures today are expected to be a little cooler than Friday with highs mainly in the 30s, but some 40s possible south, depending on the amount of sunshine today.
Across Alabama, this ridge continues to slowly weaken and crawl to the east which will allow for increased moisture to feed into the state today from the gulf around the back side of the ridge. For today, this will mean an increase in dew points, warmer high temperatures and some cloud cover.
Both SFC dewpoints and temperatures were running a bit cooler, so a slight downward nudge was made to both.
1237 AM EST Sat Jan 20 2018 High pressure will drift across the southeastern United States through the weekend. Confidence is low though, mainly due to the high overhead and the dry airmass aloft, so have continued to leave it out of the weather grids for now. Thus, should see overnight temperatures a few degrees warmer. Some members of the NAM hinting at possible low cloud/fog development above the snowpack as warmer air just above the surface overrides the colder air at the surface. The relatively dry air mass will continue to promote wide diurnal temperature swings from sub freezing early morning lows to mild afternoon temperatures. The snow pack of this depth will continue to have an influence on the air temps, so afternoon temps in the lower 50s will be more likely.
254 AM EST Sat Jan 20 2018 Through the short term, low pressure will traverse the area from the west.
The weather will be dominated by high pressure to the north for this weekend.
1213 AM EST Sat Jan 20 2018 High pressure will maintain dry and warmer weather through today. Intensifying warm advection under building upper high pressure in advance of a Cntrl Rockies-to-Plains low will drive Upper Ohio temperature well above the averages for the start of the new week.
Farther south high/mid clouds to hold longer and a bit warmer.
1229 AM EST Sat Jan 20 2018 High pressure passes to the south through Saturday, while deepening low pressure tracks across Eastern Canada. A weak cold front will pass through the area Saturday night.
Considering we're starting out fairly warm with temps in the lower 40s right now, have decided to bump a few degrees on to today's forecast with upper 40s to low 50s expected across much of the area.
Coastal trough remains over the offshore waters with light northwest winds prevalent across the bays and near shore waters.
With the majority of energy with the trough moving through the Rockies going across Colorado and Wyoming, most of the area will see a dry day.
Meanwhile, a weak upper level system, over the lower MS, valley, will continue to spread cloudiness eastward this evening.
1257 AM EST Sat Jan 20 2018 A warm front will pass later today, with some sprinkles or light rain possible.
High pressure will prevail across the region today with above normal temperatures and dry conditions.
Another upper trough will move across the region on Saturday with colder air aloft and a more unstable atmosphere.
223 AM EST Sat Jan 20 2018 High pressure will maintain dry and warmer weather through today. Intensifying warm advection under building upper high pressure in advance of a Cntrl Rockies-to-Plains low will drive Upper Ohio temperature well above the averages for the start of the new week.
Late tonight, moisture will increase in the lowest 2 km and with modest lift on the 280 to 290 K isentropic surfaces, some light drizzle/freezing drizzle is possible across portions of northeast IA into far southwest WI. Temperatures tonight will generally be in the mid 20s into the lower 30s.
Only feature to focus on tonight is the potential for some patchy freezing fog across a few southwestern valleys. Also, kept the mention of freezing fog into West Yellowstone due to recent observations.
231 AM EST Sat Jan 20 2018 A warm front will pass later today, with some sprinkles or light rain possible.
Forecast soundings across the southern valleys suggest temps will be above freezing into the evening hours with the change over to snow delayed until between 7 and 9 pm. A -30C H5 open wave is expected to push westward into Utah Saturday afternoon, with showers developing along and ahead of the associated cold front west to east during the day Saturday across eastern Utah and western Colorado. As the front pushes eastward Saturday night, much of western Colorado will see rain and/or snow with cooler air lowering snow levels throughout the night.
339 AM CST Sat Jan 20 2018 Southwesterly mid level winds will increase ahead of an approaching deep trough causing temperatures to soar well above normal today.
08z/2am temperatures are generally in the lower to middle 30s, with a few readings near 40 degrees across the far W/SW KILX CWA.
Thickening BKN/OVC cirrus clouds around 20k feet will fill in across the area by early morning ahead of an approaching upper level trough.
255 AM CST Sat Jan 20 2018 Good bit of mid and high level cloud cover over the area this morning, associated with an upper low moving across southern Louisiana. Temperatures are running considerably warmer than 24 or 48 hours ago with temperatures ranging from the mid and upper 30s from Slidell and Pearl River eastward, to the lower 50s along the lower coastal parishes. As mentioned above, as the upper low moves across southern Louisiana today, scattered showers are expected, but should see a diminishing trend by late afternoon.
113 AM EST Sat Jan 20 2018 High pressure will push off to the east through tonight.
318 AM EST Sat Jan 20 2018 High pressure will pass through the southeast states this weekend.
250 AM EST Sat Jan 20 2018 High pressure slides off the Southeast coast through the weekend.
This deck of clouds has done a good job reflecting returning long-wave radiation back to the surface and consequently warmer temperatures for the area. The remainder of the area that had experienced the clouds earlier were in the low/mid 40s with light winds. A return of more direct sun and warmer temperatures will help melt more remaining ice/snow across the region today. Speaking of temperatures, highs should warm into the low/mid 50s - a bit above seasonable norms of around 51 degrees.
/19/ Low cloud cover encompassing much of the deep south is responsible for holding temps a bit warmer thus far this evening across the region, therefore slight upward adjustment made to expected overnight temps. With the cloud cover continuing, temperatures tonight will be considerably warmer than lately with most locations not dropping below freezing.
102 AM EST Sat Jan 20 2018 High pressure will move east through the southeast states this weekend.
The period will begin with ridging ahead of a closed low across the Central Plains.
1208 AM EST Sat Jan 20 2018 Low pressure around 990mb tracking north of Lk Superior this aftn. Temps have stayed in the low to mid 30s elsewhere.
Low level ridging now working its way far enough east to allow the start of a weak return flow during this period. Tonight looks like temps will stay above freezing area-wide as surface dewpoints continue to rise on this return flow.
With this in mind our TAF sites will have lower AGL CIGS as we work up the valley to higher and higher ground elevations, so KTRI will have the lowest ceiling, once it arrives.
temperatures are ranging widely this morning from the mid 20s up to the lower 30s w/ mainly clear skies and light winds. one more nice above normal day for temps is set for the area with the remnants of the upper ridge slowly breaking down ahead of a storm system for the latter half of the weekend. Low pressure at the surface will aid in bringing in some WAA into the region allowing for daytime highs to reach mainly into the 50s.
/issued 933 PM CST Fri Jan 19 2018/ Upper low near Houston with much off shore weather wise.
1207 AM EST Sat Jan 20 2018 High pressure will prevail through the weekend.
314 AM EST Sat Jan 20 2018 High pressure slides off the Southeast coast through the weekend.
238 AM CST Sat Jan 20 2018 Clouds have returned to the Midsouth as a weak trough and associated cutoff low track along the Northern Gulf Coast. Out West a much deeper longwave trough is deepening over the Desert Southwest. The Gulf Coast low will continue to track to the East gradually weakening while the Trough out West deepens resulting in strengthening Southwest flow across the Midsouth.
A cold front moving east across the area will bring valley rain and mountain snow especially Saturday afternoon and evening.
