237 PM CST Tue Nov 10 2020 Wind speeds have begun their downward trend as the cold front continues to push well to our east. Filling in is drier air with dewpoints in the low to upper teens (a small handful in the single digits). Each passing disturbance will provide a cold front for the South Plains, though the source region for these front will be the eastern Pacific, and thus not particularly cold for this time of year.
Cold front extends from the extreme tip of northwest AR into southeast OK, with a band of scattered showers along the boundary.
155 PM MST Tue Nov 10 2020 A large trough will continue to slowly move east across the Western US Wednesday. A trailing cold front will move through our area tonight and shift winds to the northwest. A few isolated areas could see up to 3 inches of snow, particularly across the higher elevations of northern Valley and Phillips Counties.
/issued 330 PM CST Tue Nov 10 2020/ A cold front moving across Texas will enter Louisiana this evening. In addition, this cold front really wont change the high temperatures, they are still expected to be in the upper 70s to lower 80s tomorrow, but the overnight lows will be in the 50s behind the front. The cold front that passes through our region tomorrow will eventually retreat back to the north out of the Gulf as a warm front this weekend.
/Issued 219 PM CST Tue Nov 10 2020/ Cold front has pushed through the entire area this afternoon with a line of showers across northwest Arkansas. Expect locations across NE OK/ NW to see subfreezing temperatures by tomorrow morning, especially the typically cool valley locations. Warmer temperatures are expected from there as high pressure moves east.
This afternoon, a cold front extended from near Fort Smith AR to Tyler TX to San Antonio and was making slow but steady progress eastward.
254 PM MST Tue Nov 10 2020 Main vort max will continue to pull away from the region this evening, with a large upper trough settling in to the north. This will provide strengthening westerly flow across the region through the period, and breezy/windy conditions to mainly the higher terrain.
This morning's cold front has slowly been moving across the region today. A cooler night is in store across the area with lows falling into the low to mid 40s across the northern tier of counties with mid 50s expected further south.
The northern portion of Lemhi County, particularly in the higher terrain, is anticipated to receive some decent snow. The snow should diminish Wednesday evening as a transitory ridge of high pressure moves over the Northern Rockies.
Sfc analysis shows the cold front moving toward the MO bootheel. This cold front is still expected to reach our far northwestern areas around 3 am. Temperature wise, looks like cooler air will infiltrate our northwestern areas toward sunrise. Continued chances for showers will lower cigs to MVFR and even IFR overnight as a cold front approaches.
The main cold front ran south from the low into central Missouri. A stationary front ran from the low east northeast into southeast Wisconsin. Dew points were in the 50s to lower 60s east of the cold front and south of the stationary front. On Wednesday quiet and dry conditions will be seen as Canadian high pressure builds into the Midwest. Cooler with temperatures near seasonal normals.
529 PM CST Tue Nov 10 2020 Above normal temperatures finally took a tumble today across the remainder of the forecast area as the cold front passed through.
Another very humid day expected with above normal temperatures reaching the low to mid 80s. The High Surf Advisory has been extended through Wed aftn to capture 2 more high tide cycles as seas will only slowly subside to 8 ft at NOAA buoy 009.
Dense cloud cover and scattered light rain showers have overtaken the area this afternoon, thanks to the combination of an influx of tropical moisture and increasing lift from an approaching upper-level trough from the west. Temperatures have not budged most of the day and remain in the lower 70s as of 21z. Overnight, expect the coverage of showers to increase as the upper trough and its associated front approach the area. A weak cold front will swing into the area by midday Wednesday, serving as a focus for a scattered to numerous showers throughout the day. Despite weakening as it moves into the region, the cold front will take its time moving through the area.
With skies clearing out gradually tomorrow afternoon still expect high temperatures in the lower to mid 80s across the region. Lows tonight should be a little cooler north where the front makes it through, but still in the mid 60s south. Onshore flow returning Wednesday night will keep temperatures from getting much cooler than tonight.
305 PM CST Tue Nov 10 2020 As the upper trough continues to rapidly push northeast of the region this evening, our pattern will quickly transition to more zonal flow.
This system has since deepened and fully matured with a a negatively tilted trough now lifting into the Upper MS Valley and western Great Lakes region. Over the forecast area, high pressure continues to build into the region with residual low clouds beginning to scatter from west to east. Temperatures this afternoon now range from the 30s over north central KS to the low 40s over east central KS. Still looking at mainly northern stream flow well north of the area which will bring back warmer airmass regimes.
719 PM EST Tue Nov 10 2020 A cold front will provide showers tonight and cooler temperatures for the rest of the week.
553 PM CST Tue Nov 10 2020 A cold front will trigger a line of strong thunderstorms across central Illinois late this afternoon into early this evening. Once the front exits into Indiana by around midnight, the storms will come to an end and a much cooler airmass will spill into the region. 21z/3pm radar imagery shows a narrow line of strong to severe thunderstorms along an advancing cold front from near KSQI to just west of KIJX. Once the cold front passes, winds will veer to the W/NW and skies will clear from west to east. High pressure will build into the region on Wednesday, providing ample sunshine and light winds.
Cold front moving into north central Montana will drop into the area late tonight which will bring an end to the winds overnight. Still blowing snow concerns this evening but suspect temperatures close to freezing and blowing today has pretty much reduced the opportunity for more snow to move but have a mention until 2100 MST. Wednesday will again be cool with highs not much above freezing.
/issued 144 PM CST Tue Nov 10 2020/ The passage of the Pacific front last night will help keep temperatures cooler today. Highs will mostly stick to the 60s with 70s along the Rio Grande, and lows overnight will drop below freezing in Southeast New Mexico.
The upper level trough over the northern Rockies will bring snow back into northern Utah for late tonight through Wednesday.
Overnight low temperatures will be in the mid to upper 30s across the lowlands to the 20s to lower 30s across the higher elevations. Highs on Wednesday will be close to seasonal normals, generally in the mid 60s to lower 70s, with mid 40s to mid 50s across the higher elevations.
High pressure is settling over the region this evening behind the fropa that occurred earlier today. /Issued 219 PM CST Tue Nov 10 2020/ Cold front has pushed through the entire area this afternoon with a line of showers across northwest Arkansas. Expect locations across NE OK/ NW to see subfreezing temperatures by tomorrow morning, especially the typically cool valley locations. Warmer temperatures are expected from there as high pressure moves east.
237 PM MST Tue Nov 10 2020 Tonight and tomorrow should be relatively quiet across the plains, with more clouds and snow for the high mountains tomorrow afternoon. Mountain wave activity should decrease through the rest of the evening and overnight tonight as ridgetop flow decreases, but windy conditions and patchy blowing snow will still be likely tonight across the high mountains and mountain passes. The exception will be the foothills and Urban Corridor where drainage winds will keep overnight lows in the low 20s. Light snow will continue for portions of the higher terrain tomorrow, especially along the Park Range where a few inches of snow is possible by tomorrow night. Otherwise tomorrow will be quiet, with highs in the upper 40s for much of the plains and cooler across most of the higher terrain.
536 PM CST Tue Nov 10 2020 As the upper trough continues to rapidly push northeast of the region this evening, our pattern will quickly transition to more zonal flow.
The High Wind Warning continues for Arlington/Elk Mountain, I-80 Summit and Bordeaux through late this evening.
/issued 237 PM CST Tue Nov 10 2020/ Wind speeds have begun their downward trend as the cold front continues to push well to our east. Filling in is drier air with dewpoints in the low to upper teens (a small handful in the single digits). Each passing disturbance will provide a cold front for the South Plains, though the source region for these front will be the eastern Pacific, and thus not particularly cold for this time of year.
High temperatures for most of the area will likely be in the low to mid 70s despite a cloud sky. A cold front is moving into West Arkansas on pace to move across the Midsouth tonight. Even after the cold front, temperatures are expected to remain near to slightly above normal tomorrow and trend warmer through the end of the work week into the weekend.

810 PM EST Tue Nov 10 2020 It will remain warm overnight, until rain chance returns early Wednesday morning with a cold front. Temperature overnight will remain in the low 60s due to continued warm advection ahead of a cold frontal passage. A trough and its associated cold front will tap into a growing plume of moisture to produce widespread rain showers tonight and Wednesday. High pressure and drier air will diminish rain chances behind the front, although light rain should continue along and ahead of it due to persistent warm, moist advection and strong jet dynamics within southwesterly flow aloft. Cooler air will be slower to filter in behind the front, leaving area temperatures above climatological averages Wednesday.
628 PM EST Tue Nov 10 2020 South winds will continue to increase into this evening ahead of a strong cold front. Showers and isolated thunderstorms will increase later this evening as the cold front approaches.
651 PM EST Tue Nov 10 2020 It will remain warm overnight, until rain chance returns early Wednesday morning with a cold front. Insolation, a very warm atmospheric column, and mixing has resulted in record warmth today as extensive high pressure over the ern CONUS further erodes. The resulting pressure gradient between east coast high pressure and midwestern low will support more wind this evening. A trough/associated cold front will tap into a growing plume of moisture to produce widespread rain showers tonight and Wednesday. High pressure and drier air will diminish rain chances behind the front, although light rain should continue along and ahead of it due to persistent warm, moist advection and strong jet dynamics within southwesterly flow aloft.

518 PM CST Tue Nov 10 2020 Should see clearing behind a cold front that is moving quickly through the area.
Light snow with minimal accumulation is expected through Wednesday mainly in the higher terrain north of I-80.
402 PM MST Tue Nov 10 2020 20z surface analysis had weak low over southwest ND with trough into WY. Upstream trough noted over southwest Canada into the northern Rockies. Some guidance suggests a few flurries over the highest elevations. Wednesday, upper trough speeds east/southeast into the northern plains pushing a cold front through the CWA in the afternoon.
Freezing start to the morning with many locations in the Sacramento and northern San Joaquin Valley waking up to temperatures in the upper 20s to low 30s.
542 PM CST Tue Nov 10 2020 For the 00Z TAFs, a weak surface trof of low pressure will move across the terminal sites late tonight into early Wednesday morning with winds becoming north to northwest temporarily.
330 PM CST Tue Nov 10 2020 A cold front moving across Texas will enter Louisiana this evening. In addition, this cold front really wont change the high temperatures, they are still expected to be in the upper 70s to lower 80s tomorrow, but the overnight lows will be in the 50s behind the front. The cold front that passes through our region tomorrow will eventually retreat back to the north out of the Gulf as a warm front this weekend.
1100 PM CST Tue Nov 10 2020 Above normal temperatures finally took a tumble today across the remainder of the forecast area as the cold front passed through.
TFJ A large trough will continue to slowly move east across the Western US Wednesday. A trailing cold front will move through our area tonight and shift winds to the northwest. A few isolated areas could see up to 3 inches of snow, particularly across the higher elevations of northern Valley and Phillips Counties.
25 inches, with northern sections on the higher end of that range and southern sections on the lower end. The surface cold front enters the Plateau this afternoon, and exits to our east in the evening. Some post- frontal showers will linger into tonight as the midlevel trough lags behind the front.
Storm total snow accumulations are currently anticipated to be up to an inch across the Treasure and Magic Valleys, with up to 6 inches in the mountains, except up to a foot over the highest peaks. Slightly warmer temperatures expected tomorrow as the moisture moves east of the area.
We start the early morning hours with some dense fog, generally within a corridor a couple counties either side of I-29 with subtle upslope flow up the Buffalo Ridge. The high temperature forecast features a battle between favorable southwest/west flow for warming vs a fresh snowpack in many areas. Surface cold front swings thru Wednesday night with the mid level boundary lagging a bit behind.
20z surface analysis had weak low over southwest ND with trough into WY. Upstream trough noted over southwest Canada into the northern Rockies. Some guidance suggests a few flurries over the highest elevations. Wednesday, upper trough speeds east/southeast into the northern plains pushing a cold front through the CWA in the afternoon.
328 AM EST Wed Nov 11 2020 Synopsis/Discussion/Marine - Much cooler today - Wet for the weekend -- Much cooler today -- If you stepped outside lately, you've likely noticed that the late summer-like weather is long gone! A strong cold front passed over Lower Michigan a few hours ago ushering the 70 degree weather to the east. Strong west winds gusting over 40 mph are pushing much cooler air across the region.
236 AM EST Wed Nov 11 2020 A cold front will move through the region this morning, bringing rain to the area. Behind the front, high pressure will move over the Ohio Valley for the rest of the week, providing cooler and drier conditions. A big change to the weather in the middle Ohio Valley is occurring as of this writing, with a cold front moving eastward into the area, bringing an end to the warm southerly flow that has persisted for the last several days. Cold advection will be present behind the cold front, and there should be a relatively significant pressure gradient. With high pressure over the region tonight and tomorrow, dry conditions are expected.
Clear skies and dry conditions will then persist into tonight with surface winds becoming light southeasterly behind that departing high pressure. We saw no reason to stray from NBM numbers with most areas falling into the lower to middle 30s.
1120 PM CST Tue Nov 10 2020 As the upper trough continues to rapidly push northeast of the region this evening, our pattern will quickly transition to more zonal flow.
1137 PM CST Tue Nov 10 2020 Should see clearing behind a cold front that is moving quickly through the area.
Through this TAF period, periods of showers will be spreading across the region ahead of an approaching cold front.

Surface obs show cold front is just now entering northwest Stewart County, and the boundary will shift slowly southeastward through the day, moving east of the Plateau by late afternoon/early evening.
/issued 902 PM CST Tue Nov 10 2020/ A cold front has pushed into the Mid-South this evening and is now located roughly along the Mississippi River. High temperatures for most of the area will likely be in the low to mid 70s despite a cloud sky. A cold front is moving into West Arkansas on pace to move across the Midsouth tonight. Even after the cold front, temperatures are expected to remain near to slightly above normal tomorrow and trend warmer through the end of the work week into the weekend.
/Today through Tuesday/ The low pressure system that brought ice to northwest Iowa and thunderstorms to southeast Iowa on Tuesday lifted into the Great Lakes region overnight with cloud cover quickly diminishing. High pressure continues to build south of the area across Kansas and Missouri and resultant winds have already transitioned to southwesterly, increasing warm air advection into the area. This relatively warmer air across the snow pack in Nebraska, South Dakota, and into northwest Iowa has resulted in areas of dense fog, however this has largely remained outside of the cwa. High pressure will dominate the area today and keep the weather quiet.
/NEW/ /Through Tonight/ Upper level zonal flow will dominate the region today in the wake of yesterday's cold front. Much cooler early morning temperatures are expected this morning, along with a chance of patchy frost in northwestern North Texas.
241 AM CST Wed Nov 11 2020 The mature upper low that impacted the region Tuesday continues to rotate northeast into the Great Lakes region this morning. Clouds increase from the west overnight in advance of the incoming upper trough and associated cold front.
902 PM CST Tue Nov 10 2020 A cold front has pushed into the Mid-South this evening and is now located roughly along the Mississippi River. High temperatures for most of the area will likely be in the low to mid 70s despite a cloud sky. A cold front is moving into West Arkansas on pace to move across the Midsouth tonight. Even after the cold front, temperatures are expected to remain near to slightly above normal tomorrow and trend warmer through the end of the work week into the weekend.
High pressure and drier air will diminish rain chances behind the front. Cooler air will slowly filter in behind the front, leaving area temperatures above climatological averages today.
1108 PM CST Tue Nov 10 2020 For the 06Z TAFs, a weak surface trof of low pressure will move across the terminal sites this morning with winds becoming north to northwest temporarily. /Issued 542 PM CST Tue Nov 10 2020/ For the 00Z TAFs, a weak surface trof of low pressure will move across the terminal sites late tonight into early Wednesday morning with winds becoming north to northwest temporarily.
1043 PM MST Tue Nov 10 2020 Main vort max will continue to pull away from the region this evening, with a large upper trough settling in to the north. This will provide strengthening westerly flow across the region through the period, and breezy/windy conditions to mainly the higher terrain.
Initial slug of showers is taking some time to reach the surface as the lower atmosphere is rather dry. High pressure and drier air will diminish rain chances behind the front. Cooler air will slowly filter in behind the front, leaving area temperatures above climatological averages today.
This will push nighttime low temperatures into the lower 20s for central KS and upper 20s in southern KS by Fri morning.
Much cooler, but seasonable, temperatures will arrive tonight and continue through the work week as well. A vigorous cold front that triggered a line of strong to severe thunderstorms across portions of central Illinois this evening has now pushed east of I-57, bringing much cooler temperatures behind it. 21z/3pm radar imagery shows a narrow line of strong to severe thunderstorms along an advancing cold front from near KSQI to just west of KIJX. Once the cold front passes, winds will veer to the W/NW and skies will clear from west to east. High pressure will build into the region on Wednesday, providing ample sunshine and light winds.
Despite gradually intensifying westerlies aloft, much drier air locked in across the high plains of western Kansas will keep any precip chances at bay through the period.
Once the inversion does break in the morning, the lower stratus should quickly dissipate out. VFR will then dominate through the day but the lower ceilings and chances of some dense fog returns tomorrow night along the coastal areas.
231 AM EST Wed Nov 11 2020 Our record-breaking warmth streak will take a break today, as a cold front currently is making a steady march eastward across the region. Then high pressure will build into the region. However for points staying under the cloud cover, like the Lake Cumberland and I- 75 counties, the highs today likely will be this morning. That high pressure will stay to our north tonight, keeping us with a steady north wind and allowing lows to fall to the upper 30s to low 40s for most locations.
254 AM CST Wed Nov 11 2020 High pressure was building over the area early this morning as the system that brought the rain and severe weather moved off to the east. Today, dry and rather quiet weather is expected today as the high pressure continues to build over the area.
1216 AM EST Wed Nov 11 2020 A cold front will provide showers tonight and cooler temperatures for the rest of the week.
Near the surface, a weak area of low pressure is situated across southeast Colorado. High pressure will shift off to the east of the FA. A few teens cannot be ruled out along the lower Arkansas river basin near the Colorado border. With weak lee troughing, light winds are expected during the daytime.
325 AM EST Wed Nov 11 2020 Today will be the wettest day of the week as an incoming cold front interacts with deep tropical moisture. Coverage will increase through the day, particularly by this afternoon and evening as the aforementioned cold front pushes into the forecast area.
