542 AM CST Thu Nov 14 2019 Lingering clouds across the area this morning have helped to keep overnight temperatures a bit warmer than previously anticipated.
Mainly Dry with Another Cold Front. A weak cold front today will bring winds from the north, along with slightly cooler air; however, high today will likely be in the 50s. For tonight, light winds and radiational cooling will produce lows a few degrees below freezing.
526 AM EST Thu Nov 14 2019 High pressure will move east of the state bringing milder temperatures today and Friday. A dry cold front will push through the area Friday night bringing a return to colder temperatures for the weekend.
345 AM CST Thu Nov 14 2019 Early morning sfc analysis shows high pressure centered over the Mid-Atlantic/New England ridging swwd through the wrn Gulf region. In addition, a trof/weak low is noted off the middle/upper TX coast and a weak cold front is noted from low pressure over the Great Lakes through the middle Mississippi Valley to the srn Plains. Water vapor imagery shows a closed low aloft pushing ewd from Mexico in to deep srn TX. Sfc obs indicate much warmer temps than previously expected with readings generally in the mid/upper 40s and slowly warming. As the low aloft opens/ejects enewd today, patchy rainfall will continue to develop/move newd across the forecast area. Curious to see what temperatures will do today as cooling overnight has been fairly limited and progged highs for today aren't much warmer than current readings.
Friday, winds return out of the south ahead of an approaching trough. Not overly confident that this low level layer is deep enough to result in drizzle or freezing drizzle. If subsequent model runs increase the depth of the low level moisture this mention may need to be expanded.
617 AM EST Thu Nov 14 2019 High pressure will bring fair weather to NY and PA today and Friday.
910 AM EST Thu Nov 14 2019 Update/Synopsis/Aviation - Freezing drizzle into this evening - No big storms and continued colder than normal Added freezing drizzle to the forecast for today as soundings show the DGZ drying out and current local observations of snow grains and freezing drizzle mix. Road surfaces are below freezing in most places and any patches of heavier freezing drizzle could cause untreated roads to become icy through the afternoon and evening. We are watching for the possibility of a little freezing drizzle as the snow moves out this morning. The persistent upper trough funneling the arctic air into the area will get kicked out by Friday, and a nice upper ridge moves in for a few days.
A little warmer today as the flow aloft backs to northwest with increasing heights and thicknesses. Rather nice warming trend to end the workweek as the flow aloft backs to westerly, helping to induce a decent surface lee trough. Even more mild as the low and mid level gradients strengthen with downslope warming west winds helping to keep most low temperatures slightly above freezing.
/19/ Today and Tonight - A mid/upper low, currently observed on water vapor imagery spinning over Northeast Mexico, will shift east across South Texas, and along the north central gulf coast through early Friday morning. As it does so, it'll weaken and phase with a more pronounced trough likewise swinging east into the Deep South early Friday morning.
539 AM CST Thu Nov 14 2019 Mostly cloudy and cold conditions will prevail across central Illinois today, with afternoon high temperatures only reaching the lower to middle 30s. A weak cold front currently analyzed along the Mississippi River will work its way eastward across central Illinois today. Readings will mainly be in the lower 30s. High pressure will provide mostly sunny skies and light winds on Friday.
as a cold front with north winds around 10 KTS moves through. VFR conditions continue this afternoon and overnight as cooler and drier air moves into the region. Band of light showers extended from Sonora to Junction at 5 AM should dissipate by midmorning as an upper low west of Del Rio moves east. Mainly Dry with Another Cold Front. A weak cold front today will bring winds from the north, along with slightly cooler air; however, high today will likely be in the 50s. For tonight, light winds and radiational cooling will produce lows a few degrees below freezing.
Expect some mostly cloudy skies, particularly early in the day, in the wake of a disturbance that passed through the lower Great Lakes yesterday evening. While radar did show some echoes, very dry air in the low levels kept any of this from making the surface, as expected.
Portions of northern Elko County may see some brief shower activity Friday night, otherwise dry, with slightly cooler though still above normal temperatures for the weekend.
324 AM CST Thu Nov 14 2019 Scattered to broken low-level stratus continues to fill in behind the departing cold front, helping to moderate temperatures slightly despite ongoing CAA with northwest surface flow. Residual stratus deck will quickly move downstream through the morning as broad surface ridging advances into the area from the west. A brief late-week ridging pattern aloft will give way to a deepening upper trough by the late weekend.
322 AM CST Thu Nov 14 2019 Mostly cloudy and cold conditions will prevail across central Illinois today, with afternoon high temperatures only reaching the lower to middle 30s. A weak cold front currently analyzed along the Mississippi River will work its way eastward across central Illinois today. Readings will mainly be in the lower 30s. High pressure will provide mostly sunny skies and light winds on Friday.
410 AM CST Thu Nov 14 2019 Today and Tonight - A mid/upper low, currently observed on water vapor imagery spinning over Northeast Mexico, will shift east across South Texas, and along the north central gulf coast through early Friday morning. As it does so, it'll weaken and phase with a more pronounced trough likewise swinging east into the Deep South early Friday morning.
414 AM CST Thu Nov 14 2019 Lingering clouds across the area this morning have helped to keep overnight temperatures a bit warmer than previously anticipated.
Weak inverted troughing can be viewed in the wind field over ECFL just inland from the east FL coast. Former cold frontal boundary lying quasi-stationary over south Florida is forecast to lift back northward today as a warm frontal boundary. To the north high pressure along the eastern seaboard will push away from the coast into the western Atlc. This feature is forecast to become an open trough as it presses eastward across the northern Gulf and eventually teams up with additional vigorous upper troughing dropping southward out of the central/southern Plains to align over the Gulf Coast States by sunrise Fri morning.
530 AM EST Thu Nov 14 2019 High pressure departs today, but continued below normal temperatures expected. KRLX 88D indicates some light echoes over central and southeast OH early this morning, but a large dry layer in the lower levels of the atmosphere should preclude any precip from reaching the ground. Temps will continue to moderate some today, with highs noticeably warmer than the past couple of days. However, some weak troughing may occur with H85 temps actually lowering a bit during the day.
Surface analysis late this morning showed a large but weak cold front stretching from Michigan across Indiana to southern Illinois. GOES16 showed some stratocu along and in the wake of the cold front across NW Indiana and Illinois. Aloft a broad trough was in place across the eastern half of the United States. This was effectively blocking and gulf or tropical flows of moist air into the region.
No significant concerns in the short term with dry weather and somewhat warmer temperatures expected. An upper level trough pivoting east through the Plains will deepen into a closed low over the Deep South by Friday. At the surface, a cold front will make passage today. The low level moisture is relatively shallow around 950 mb, and shows up in the NAM, and to a lesser extent, GFS forecast soundings.
Warmer this weekend with well above average high temperatures. Partly to mostly cloudy skies cover the region early this morning as the offshore trough approaches. The marine layer is also deepening ahead of the trough (indicated over 3k ft in depth on the Ft Ord profiler), so may see a bit of stratus make its way inland into the Sacramento area early this morning as surface gradients trend onshore. Cooler temperatures (though still around 5-10 degrees above average) along with partly to mostly cloudy skies are expected today and Friday as the trough moves through. May see a better chance of more widespread stratus moving into the Central Valley later tonight into Friday morning as the trough axis nears the coast (HREF probabilities of MVFR ceilings are greater than 90% from about Chico southward in the Sacramento Valley).
The upper trough will continue to swing east through the area today to slowly push this activity out later this evening. For Friday, high pressure will take hold and keep sunny skies with light, northerly winds throughout the day. While tonight's low temperatures will not be the record values from last night, they will still hit freezing area-wide.
1029 AM MST Thu Nov 14 2019 High pressure will build across the region through Friday maintaining warmer than normal temperatures.
1143 AM CST Thu Nov 14 2019 Scattered to broken low-level stratus continues to fill in behind the departing cold front, helping to moderate temperatures slightly despite ongoing CAA with northwest surface flow. Residual stratus deck will quickly move downstream through the morning as broad surface ridging advances into the area from the west. A brief late-week ridging pattern aloft will give way to a deepening upper trough by the late weekend.
Patchy IFR/MVFR fog in the lower valleys in Baker and Valley counties this morning.
An upper level low and surface reflection will develop across the southeastern U.
A weak cold front has passed east of the Wabash River as of 10 a. Otherwise, temperatures should stall out late this morning to early afternoon ranging from the low to mid 30s most areas and upper 30s south of I-70 in the cold advection behind the front. A weak cold front currently analyzed along the Mississippi River will work its way eastward across central Illinois today. Readings will mainly be in the lower 30s. High pressure will provide mostly sunny skies and light winds on Friday.
346 PM EST Thu Nov 14 2019 High pressure will move east of the state bringing milder temperatures today and Friday. A dry cold front will push through the area Friday night bringing a return to colder temperatures for the weekend. Fair weather will continue overnight as high pressure noses in from the west.
This all comes as an upper level trough swings across the northern Gulf of Mexico. Temperatures have remained in the 40s and 50s today thanks to abundant cloud cover and the approaching upper level trough. Clouds should gradually clear from northwest to southeast tonight and allow temperatures in the Delta to drop to or slightly below freezing. Areas that see cloud cover will remain above freezing but still in the 30s. Highs tomorrow will be in the lower 50s north to mid 50s south under plenty of sunshine.
Even with the sky cover, temperatures are on track with northeastern SD reaching the upper 30s, to the lower 50s over south central SD. Friday, winds return out of the south ahead of an approaching trough. Not overly confident that this low level layer is deep enough to result in drizzle or freezing drizzle. If subsequent model runs increase the depth of the low level moisture this mention may need to be expanded.
311 PM EST Thu Nov 14 2019 Updated at 252 PM EST Thu Nov 14 2019 Synoptically, upper level troughing extends from Canada southward through the eastern third of the US with ridging across the Rockies and the western Atlantic. But a quiet short term can be expected as a moisture-starved cold front passes through the Ohio Valley this evening. Expect morning lows to range from the low 20s across southern Indiana and gradually increase southward to mid 20s across southern Kentucky with highs reaching into the the low to mid 40s.
Some steam fog over area rivers and lakes will be possible tonight due to the combination of light winds, clear skies, high surface RH values and warmer than air water temperatures.
1121 AM MST Thu Nov 14 2019 Dry northwest flow continued over eastern Utah and western Colorado on the eastern side of a persistent ridge of high pressure over the western U. The ridge migrates eastward during the day according to model data with the ridge axis reaching central Utah by 00Z. Cirrus carried over the top of the ridge will spread over the area during the afternoon. The ridge flattens and its axis pushes to just west of the Continental Divide by 12Z Friday. With the ridge to the east a weak zonal flow develops over the region on Friday bringing partly sunny skies and a small increase in afternoon temperatures for most locations.
1124 AM EST Thu Nov 14 2019 High pressure will move east of the state bringing milder temperatures today and Friday. A dry cold front will push through the area Friday night bringing a return to colder temperatures for the weekend.
Updated at 308 AM EST Thu Nov 14 2019 Mid to high level clouds are streaming into the Ohio Valley ahead of a weak cold front this morning. Winds will remain out of the south and southwest through most of day until a weak cold front moves through this evening. Tonight, skies should clear out and high pressure will try to nudge into the area from the west.
A low pressure system will slide across to our south overnight and into tomorrow. Northerly winds expected tomorrow once we get on the backside of the low.
A weak cold front today will bring winds from the north, along with slightly cooler air; however, high today will likely be in the 50s. For tonight, light winds and radiational cooling will produce lows a few degrees below freezing.
245 PM CST Thu Nov 14 2019 WV imagery shows an upper level low over the central Texas Gulf Coast, which has resulted in rain for much of the ern half of the state today. Closer to home, a cold front moved through West Texas and Southeast New Mexico last night and this morning.
Upper level low making its way across south TX will link up with a broader troughing pattern east of the region today. A front has moved over our northern counties this afternoon and will continue to push southeast in association with the trough axis over north TX. Max temperatures this afternoon have trended cooler a couple of degrees, especially for northern areas with clouds hanging around longer than previously anticipated.
Calm winds from a nearby high pressure overnight will allow for strong radiational cooling which will elevate the surface RH values. /Issued 946 AM CST Thu Nov 14 2019/ A weak cold front has pushed through the area this morning with only a wind shift and some lower clouds along and behind the front. A warming trend is expected to start tomorrow and continue through the weekend with mid-level heights rising in the wake of the departing upper trough.
1144 AM EST Thu Nov 14 2019 High pressure will move east of the state bringing milder temperatures today and Friday. A dry cold front will push through the area Friday night bringing a return to colder temperatures for the weekend.
taking place between high pressure dropping through the Central Plains and a cold front pushing into northern MN/ND. The cold front over MN/ND this afternoon will push into the area tonight -looking dry but bringing with it more stratus cloud cover going into Friday morning. After a mostly cloudy start to Friday, high pressure building south out of Ontario Canada will slowly clear clouds from northeast to southwest through the afternoon. Warm air advection kicks in Friday night with winds becoming southerly on the backside of the departing high and approaching low pressure/cold front over southern canada/the Dakotas.
Its a little cooler with lower 40s northwest. Weak/dry surface cold frontal passage will result in wind shift SW to NW by no later than 15/07Z.
Lingering clouds across the area this morning have helped to keep overnight temperatures a bit warmer than previously anticipated.
1125 AM CST Thu Nov 14 2019 08Z water vapor imagery showed a broad upper trough over the plains and Great Lakes with upper ridging along the west coast. At the surface, high pressure was slowly building south into the central plains with a weak frontal boundary across eastern OK and central MO. Clearing skies and light winds should allow for temps overnight to fall into the lower and middle 20s.
946 AM CST Thu Nov 14 2019 A weak cold front has pushed through the area this morning with only a wind shift and some lower clouds along and behind the front. A warming trend is expected to start tomorrow and continue through the weekend with mid-level heights rising in the wake of the departing upper trough.
Satellite imagery shows the upper low over the Middle Texas coast near Rockport moving to the east-northeast. The coastal trough/low pressure area appears to have moved east of the offshore waters. As the upper low exits the region, there will be wraparound moisture that will affect the coastal plains. North winds will continue to gradually increase as the gradient increases between the low pressure area over the northwest Gulf of Mexico and high pressure building into south Texas. North winds will continue to increase through the afternoon as the gradient strengthens between to the low east of the offshore waters and high pressure building into south Texas.
/issued 132 AM CST Thu Nov 14 2019/ Upper level low pressure area across southern Texas is currently producing some showers on the back side of this system along the U. As the upper low continues to move east the precipitation should be out of the forecast area by 14/12z.
232 PM EST Thu Nov 14 2019 A low pressure center is expected to develop off of the Southeast U.
Tonight and Friday The main concern for the next 24 hours to mainly be on cloud trends as a dry cold front moves through the area. The 19Z MSAS surface analysis showed a weak ridge of high pressure that extended from the central plains into the Upper MS Valley. A cold front extended southwest from western Ontario into the northern Plains. Visible satellite imagery showed the last of the low clouds eroding as drier air advects across the state. However, any clearing trend appears to be short-lived as clouds are quickly approaching ahead of the cold front. The cold front is forecast to drop southeast, reaching central/ east-central WI by daybreak. High pressure centered over southern Ontario with a ridge extended southwest all the way to TX, will be our main weather feature for Friday.
136 PM EST Thu Nov 14 2019 High pressure will move east of the state bringing milder temperatures today and Friday. A dry cold front will push through the area Friday night bringing a return to colder temperatures for the weekend. Fair weather will continue overnight as high pressure noses in from the west.
As the low pressure system to our south moves off to the east, northerly winds pick up on Friday.
A ridge of high pressure at the surface extended from the western Texas Panhandle through northern Kansas mid-afternoon, which resulted in a nice drop off in winds today. Friday's weather will be warmer, with highs well into the lower to mid 60s, as upper level ridging continues to build across the Rockies and adjacent High Plains.
Chattanooga Airport, TN 47 35 53 33 / 10 10 10 0 Knoxville McGhee Tyson Airport, TN 46 32 53 31 / 0 10 10 0 Oak Ridge, TN 46 31 52 29 / 0 10 10 0 Tri Cities Airport, TN 47 27 51 27 / 0 10 10 10.
This has enabled a return southerly wind flow and warmer temperatures. At 1 pm, the mercury is now into the lower 50s for many areas. After lows tonight around 25 to 30, the highs for tomorrow will top out at around 45 to 50 degrees.
234 PM CST Thu Nov 14 2019 A weak cold front currently stretches from near Greenville, Mississippi northeastward to Corinth, Mississippi.
High pressure in general is expected across the area through the end of the week.
weak ridging across the Central Plains will give way to a zonal pattern heading into Friday, with warmer air advecting east of the Rockies. Temps tonight will be right around climatology in the 25-30 degree range, then on Friday we'll tap into the warmer airmass with aftn temps forecast to reach the upper 50s/low 60s (above seasonal normal highs).
Otherwise, quiet weather is in store for the rest of today as high pressure begins moving in. High temperatures have remained cool, with highs in the low to mid 40s and lows tonight expected to drop into the upper teens to low 20s. As high pressure continues to build into the area tonight, clear and calm conditions will provide a potential for some patchy fog development across the area tonight until shortly after sunrise Friday.
1231 PM EST Thu Nov 14 2019 High pressure will bring fair weather to NY and PA today and Friday.
Updated at 252 PM EST Thu Nov 14 2019 Synoptically, upper level troughing extends from Canada southward through the eastern third of the US with ridging across the Rockies and the western Atlantic. But a quiet short term can be expected as a moisture-starved cold front passes through the Ohio Valley this evening. Expect morning lows to range from the low 20s across southern Indiana and gradually increase southward to mid 20s across southern Kentucky with highs reaching into the the low to mid 40s.
429 PM MST Thu Nov 14 2019 Another mostly sunny and mild day is happening as the CWA remains underneath a ridge of high pressure. High clouds will increase from the west later this afternoon into the evening as the ridge axis shifts overhead and the flow eventually shifts to a southwest flow for Friday.
A positive tilted trough axis is back to the west of our area with rain well south of Middle Tennessee.
Overnight lows will be cooler tonight dropping into the mid to upper 20s. Continued warm air advection into the region Friday and Friday night will allow Friday night lows to be slightly warmer in the upper 20s to low 30s.
/issued 234 PM CST Thu Nov 14 2019/ A weak cold front currently stretches from near Greenville, Mississippi northeastward to Corinth, Mississippi.
For tonight, the low clouds north of highway 2 will sag southward and cover most of the area again. Very late tonight into Friday morning, there could be some patchy fog, stratus, or freezing drizzle over central North Dakota. Winds will turn back to the southeast on Friday, but highs will be slightly cooler.
The high clouds will increase tonight and by Friday morning expect mostly cloudy skies. Because of the high clouds, temperatures may be slow to warm. Breaks in the high clouds along with the warm airmass should result in highs in the 60s across northeast Colorado Friday afternoon. Models have upper ridging moving into Colorado tonight and over the CWA on Friday. The low level winds are progged to be fairly weak overnight and a mix of normal drainage patterns and downsloping. For temperatures, Friday's highs should be 3-6 C warmer than today's highs.
Lows across the entire area will fall to at or below freezing.
225 PM MST Thu Nov 14 2019 Another mostly sunny and mild day is happening as the CWA remains underneath a ridge of high pressure. High clouds will increase from the west later this afternoon into the evening as the ridge axis shifts overhead and the flow eventually shifts to a southwest flow for Friday.
Latest water vapor imagery shows nearly meridional flow overhead with upper ridging building across the western CONUS.
There may be some isolated freezing fog across the valley locations of NW AR, however most model guidance doesnt support this scenario. Warmer temperatures will continue the next several days, though cloud coverage will increase the latter half of the weekend as an upper trough slides through the central and high plains.
712 PM EST Thu Nov 14 2019 As a low pressure system continues to develop over the Eastern Gulf of Mexico, showers continue to make their way onshore. A cold front will push through the area tomorrow, leading to additional showers.
