1034 PM CDT Sat Oct 30 2021 Surface cold front roughly splitting the coverage area early this afternoon with gusty northwesterly winds behind it and temperatures in the 60s out ahead of it. Temperatures overnight fall to near or below the freezing mark although with winds remaining elevated, should prevent the full cooling potential. Base of the upper level trough sits over the region for Halloween with mostly clear skies and somewhat breezy northwest winds in the 10-20 mph range. Afternoon temperatures will be noticeably cooler than today or mainly 40s across the region. Forecast for the upcoming work week looks to be characterized by below normal temperatures and mostly dry conditions as the region sits on the backside of upper level troughing to the east with developing ridging to our west by late week.
326 AM CDT Sun Oct 31 2021 Message of the Day - Today (Halloween) will be mostly sunny by the afternoon with high temperatures in the low to mid 50s. Discussion The dry cold front has been making its way through our area overnight, with it currently (3 AM) sitting from Butler, MO to about Moberly, MO. For tricker treaters this afternoon and evening, temperatures will start off in the low to mid 50s and then drop to the mid to upper 40s by sunset. Below normal temperatures will stick around for the week thanks to low pressure over northeast Canada and its very little movement. The multiple nights with low temperatures near or below freezing could very well lead to the end of this year's growing season.
Temperatures Today will be below seasonal averages, with highs in the lower to middle 70s. High pressure will continue to build from the northwest Tonight through Monday, with dry weather prevailing.
The coldest temperatures will be found across the eastern Ozarks with lows in the lower 30s.
(Today through Monday afternoon) We're currently watching the slow-moving cold front this morning as it pushes through the region. This front will give us some cooler and near-normal temperatures by the afternoon, with low 70s expected across SE New Mexico and the Permian Basin. With mostly clear skies overnight, lows Monday morning will be in the low to mid 40s across the region.
1205 AM CDT Sun Oct 31 2021 Key Points: -Cooler than normal conditions expected this week as a series of disturbance introduce cooler air to the region. cold front has worked into northern and central Nebraska with gusts in the 25-35 knot range behind the front. Upper trough remains across the Great Lakes region through much of the week with waves dropping into the Midwest in northwest flow.
Closed low at coast is drifting farther north, bringing precipitation more directly into the southern zones, but eventually nearly all over except perhaps the northeastern corner of the forecast area.
246 AM CDT Sun Oct 31 2021 Pesky SFC/Upper lows finally out of the picture as they have pushed up into New England.
SHORT TERM (Now through Monday): Nothing overly spooky expected across Deep South Texas this Halloween, with a ridge of high pressure continuing to build into Monday.
Cold front will move into NE OK shortly, and pass through all sites by around 15z. Forecast is on track this evening with quiet conditions ahead of the approaching cold front currently into far NW OK. VFR conditions will prevail through much of the period, with the possible exception of some MVFR cigs filtering in behind a passing cold front tomorrow morning. Settled conditions will continue into tomorrow, though temperatures across the northern half the area will cool down as a result of a cold front moving through the area, along with a period of enhanced cloud cover behind the front. Though a wind shift is expected to occur across the entire area, the cooler air will lag some, so temperatures across the southern zones will likely rival those observed today.
Further northwest a band of clouds associated with a cold front is positioned over central Iowa. Temperatures look to top out in the 50s, which is roughly 5 degrees cooler than normal for Halloween day. Winds should gradually lessen after dark as high pressure builds in from the west.
High temperatures today will run just slightly below normal and in the low 60s to 70s under mostly sunny skies.
N of the cold front high temps Mon will be 10-15 degrees cooler than today, despite sunny skies.
(Today and tonight) Cold front will continue to move south toward the Red river this morning and into north during the first part of the day today.
A cold front will move through the area this morning, bringing breezy northeasterly winds to all terminals. /issued 253 PM CDT Sat Oct 30 2021/ A progressive low amplitude ridge continues its pass east across the region this afternoon. In the wake of the cold frontal passage, temperatures on Monday will be fairly similar to Sunday with otherwise quiet weather expected under nearly zonal upper flow.
313 AM CDT Sun Oct 31 2021 A west northwesterly flow continued across the Central Plains this morning while a mid level trough was moving across eastern Manitoba and the Dakotas at 0730Z. A cold front extended from northwest Missouri across southeast Kansas into southwest Oklahoma. With some clouds and cold advection with northerly winds, highs will will be in the low to mid 50s today.
546 AM MDT Sun Oct 31 2021 The cold front continues to slowly slide southward across the area early this morning. And there are even a few areas of patchy freezing drizzle.
1028 AM EDT Sun Oct 31 2021 A band of closed-cell stratocumulus was spoiling the morning sunshine across the Lower Keys, otherwise it was a pleasant morning with temperatures in the upper 70s and dewpoints in the lower to mid 60s. While the deep upper low continues to lift north through New England, a trough axis at 850-700 mb remains northwest of the Keys. There remains good news offshore in the southeast Gulf of Mexico with Pulley Ridge continuing to decrease. Continuing from synopsis, a ridge of high pressure will gradually build across the region over the next few days.
423 AM CDT Sun Oct 31 2021 Sunny and mild conditions return to the Midsouth today, following the exit of the large upper level low pressure system that dominated our weather late last week. This afternoon will see the mildest temperatures of the week, ahead of dry cold frontal passage tonight. Upper level heights across the Midsouth will decrease through midweek, courtesy of a deepening longwave trof centered over eastern Canada and extending south through much of the eastern CONUS.
309 AM MDT Sun Oct 31 2021 With the cold air mass and high pressure in place from the Canadian prairie, skies will remain mostly clear and sunny, and temperatures will fall below normal as the cold air mass only slowly moves eastward through the first half of this week. Later this week, a highly amplified ridge of warmer high pressure slowly moves from the continental divide over the high plains region, allowing temperatures to climb slightly above normal.
1001 AM EDT Sun Oct 31 2021 High pressure will approach the area from the Deep South today and will linger into the mid week. We should see a nice warm up to the low 70s by mid afternoon today. Using a blend of the cooler MOS, low temperatures are expected to range in the mid 40s inland to the low to mid 50s along the coast. High pressure will prevail across the area.
620 AM CDT Sun Oct 31 2021 A cold front will move through the state today. The front will pass through dry but will bring cooler air in for tonight. Today Through Monday Night A large upper low pressure system continues over the eastern U. with an upper ridge over the Rockies. The upper ridge will weaken as it moves east today and northwest flow will become zonal. Northwest flow returns to the area Monday night as an upper low moves north of the Great Lakes. A cold front will move through the state today but a fair amount of heating will occur ahead of the front. Cooler conditions tonight will lead to some patchy frost in the far north.
Cold front presently near I-44 will continue to move south past all TAF sites by 18z. /Issued 234 AM CDT Sun Oct 31 2021/ Cold front is approaching Tulsa from the northwest early this morning. The front will continue south and east across the region today and will eventually stall in the terrain of SE OK and W AR by tonight, as the cooler air will become increasingly more shallow with southward and eastward extent. Temps down near the Red River may be around 20 degrees warmer than across NE OK and NW AR.
1015/1415Z: Batch of showers associated with final vort lobe rotating around departing upper trough will exit the southeast zones by noon. but still a weak secondary cold front to move through the state tonight will bring a chance of some showers across the northwest mountains.
Temperatures this morning were on the cooler side as good radiational cooling occurred overnight thanks to light winds and clear skies. Today, we should be in the lower to mid 70s, which isn't scary at all. WIth high pressure in control of the region, a gorgeous day is underway across the ArkLaMiss. However, high pressure will build into the region, and ample sunshine today will bring the temps back up into the low to mid 70s by later this afternoon.
Patchy fog will be possible early tomorrow morning as well (with the highest risk for AEX and ARA).
Upper low in western Oregon maintained thunderstorms through the night in eastern Oregon, especially in Malheur County.
A cold air mass will filter into the Northland today as a deep trough settles over the Great Lakes region.
923 AM CDT Sun Oct 31 2021 (Issued 922 AM CDT Sun Oct 31 2021) Clouds behind a cold front that moved through earlier will clear out from west to east late this morning to mid-afternoon, which should allow temps to hit forecast highs around 50. DDV (Issued 340 AM CDT Sun Oct 31 2021) Today through Monday night: Cold front exiting off to our east this morning. Bufkit soundings show the moisture in the lower levels that will decrease later this morning and into the afternoon hours. Overall the column remains dry through Monday night with a cool regime with the lower level thermal trough in place. Looks like most areas will have freezing temperatures for Monday night.
Pesky SFC/Upper lows finally out of the picture as they have pushed up into New England.
259 AM PDT Sun Oct 31 2021 Increasing onshore flow and weak troughing aloft will result in cooler conditions through the early part of the week. A pair of short wave troughs pass through today and Monday will lead to continued cooling with high temperatures a few degrees below normal and an increase in high cloud cover. Onshore winds pick up a bit each afternoon and evening in the mountains and deserts with the highest gusts generally around 35 mph.
636 AM CDT Sun Oct 31 2021 (Today and Tonight) A cold front will move south into the Big Country this morning, and should stall by early this evening along a Mertzon to Cross Plains line. Temperatures south of this front will be warm again today across the southern half of our area with highs in the lower to mid 80s. North of this front, temperatures will be cooler with highs in the lower to mid 70s across most of the Big Country.
Expect precipitation will ramp up early Sunday evening with the highest precipitation rates from roughly 10PM through 4AM, then winding down later Monday morning. Ensemble guidance remains consistent in showing the upper pattern taking on a blocky omega appearance with a high amplitude ridge over the Rockies and trofs/lows on either side.
High pressure building into the local area from the northwest will help to further dry conditions, with forecast PWATs falling to generally 0. Northwest winds will also work to keep temperatures on the lower side, with highs in the mid 70s from the Orlando area northward, to the upper 70s to low 80s across the south.
We are off to a chilly start this morning, particularly for wind sheltered valleys across northwest Montana where temperatures have dropped into the low 20s to teens. In Idaho, lows in the upper 20s to just below freezing are anticipated. Weak high pressure will generally be in control of the weather pattern for much of this upcoming week. There are indications a few disturbances will move through the ridge which will bring a few periods of increased clouds and some shower activity.
A cold front moving through has already shifted winds to out of the N at all terminals except KFST. (Today through Monday afternoon) We're currently watching the slow-moving cold front this morning as it pushes through the region. This front will give us some cooler and near-normal temperatures by the afternoon, with low 70s expected across SE New Mexico and the Permian Basin. With mostly clear skies overnight, lows Monday morning will be in the low to mid 40s across the region.
/issued 423 AM CDT Sun Oct 31 2021/ Sunny and mild conditions return to the Midsouth today, following the exit of the large upper level low pressure system that dominated our weather late last week. This afternoon will see the mildest temperatures of the week, ahead of dry cold frontal passage tonight. Upper level heights across the Midsouth will decrease through midweek, courtesy of a deepening longwave trof centered over eastern Canada and extending south through much of the eastern CONUS.
With abundant cloud cover and the increasingly cold airmass, temperatures will only top out in the 40s for most of Nebraska and only the low 50s imp arts of northern Kansas.
632 AM CDT Sun Oct 31 2021 Message of the Day - Today (Halloween) will be mostly sunny by the afternoon with high temperatures in the low to mid 50s.

Later this week, a highly amplified ridge of warmer high pressure slowly moves from the continental divide over the high plains region, allowing temperatures to climb slightly above normal.
Temperatures in the lower to mid 60s expected to warm up into the mid to upper 70s by mid afternoon. Patchy fog will be possible early tomorrow morning as well (with the highest risk for AEX and ARA).
/issued 252 AM CDT Sun Oct 31 2021/ SHORT TERM (Now through Monday): Nothing overly spooky expected across Deep South Texas this Halloween, with a ridge of high pressure continuing to build into Monday.
(Today and Tonight) A weak cold front will move south into the Big Country this morning, and should stall by early this evening along a Mertzon to Cross Plains line. Temperatures south of this front will be warm again today across the southern half of our area with highs in the lower to mid 80s. North of this front, temperatures will be cooler with highs in the lower to mid 70s across most of the Big Country.
606 AM CDT Sun Oct 31 2021 (Today and tonight) Cold front will continue to move south toward the Red river this morning and into north during the first part of the day today.
No significant changes were made to today's forecast, with afternoon highs in the middle to upper 60s west, with lower 60s east (and upper 50s atop the higher plateaus). The cold front currently to the west will move through the Tennessee Valley late tonight into early Monday as the main upper level trough digs in over the Great Lakes region. The front will pass as a dry cold front. PW values will remain below the mean for early November climatology ahead of the cold front. Mostly sunny skies by Monday afternoon will allow for temperatures to warm into the low to mid 60s. Broad troughing will features across the Upper Midwest eastward across the Great Lakes into New England.
A west northwesterly flow continued across the Central Plains this morning while a mid level trough was moving across eastern Manitoba and the Dakotas at 0730Z. A cold front extended from northwest Missouri across southeast Kansas into southwest Oklahoma. With some clouds and cold advection with northerly winds, highs will will be in the low to mid 50s today.
A couple of disturbances later this week could bring showers and cooler temperatures with the first one looking to arrive on Monday evening. Clouds will be in the increase tonight as an upper ridge tries to quickly move into the area. The ridge will move out of the area Monday afternoon with light showers spreading from west to east.
VFR through today and although winds should be predominantly north/northwesterly and less than 5kts, the high pressure ridge over the area will likely result in some variability. However, high pressure will build into the region, and ample sunshine today will bring the temps back up into the low to mid 70s by later this afternoon.
NE winds are increasing in weak of the cold front, now located across the srn PB. A cold front moving through has already shifted winds to out of the N at all terminals except KFST. (Today through Monday afternoon) We're currently watching the slow-moving cold front this morning as it pushes through the region. This front will give us some cooler and near-normal temperatures by the afternoon, with low 70s expected across SE New Mexico and the Permian Basin. With mostly clear skies overnight, lows Monday morning will be in the low to mid 40s across the region.
1209 PM CDT Sun Oct 31 2021 (18Z TAFS) The cold front is s of all TAF sites and gusty ne will decrease starting by 21Z, if not a little earlier. Otherwise satellite shows a trough approaching from the which will result in an increase in high clouds. Otherwise isentropic ascent will result in the development of low clouds aloft the shallow cold front, however their arrival at MAF/HOB would not be until around 15Z/Mon. (Today through Monday afternoon) We're currently watching the slow-moving cold front this morning as it pushes through the region. This front will give us some cooler and near-normal temperatures by the afternoon, with low 70s expected across SE New Mexico and the Permian Basin. With mostly clear skies overnight, lows Monday morning will be in the low to mid 40s across the region.
A cold front will shift across the remainder of the state this afternoon. Today Through Monday Night A large upper low pressure system continues over the eastern U. with an upper ridge over the Rockies. The upper ridge will weaken as it moves east today and northwest flow will become zonal. Northwest flow returns to the area Monday night as an upper low moves north of the Great Lakes. A cold front will move through the state today but a fair amount of heating will occur ahead of the front. Cooler conditions tonight will lead to some patchy frost in the far north.
Monday will not be as windy, but we'll see a renewed diurnal increase of the cu field as cooler mid- level air continues to filter south.
The circulation center of the Denver cyclone is just north-northeast of DIA right now. Upslope flow in the lower levels is expected to persist overnight and Monday. The low level moisture is fair over most of the CWA, but deeper over the northern border. I will put the highest pops in over the northern border in association with the jet max tonight and Monday.
The pressure gradient continues to slowly weaken as the cold front that passed through the area this morning advances eastward, but it will remain breezy tomorrow with 10-15 knot winds and gusts up to 20 knots. Otherwise look forward to partly to mostly sunny skies across most of the area with high pressure building in at the surface to start the week. The forecast continues to remain consistent- troughing at upper levels has moved in and will continue to dominate the synoptic flow with high pressure at the surface.
Temps this evening will fall into the lower 30s and upper 20s during trick-or-treating time, so be sure to dress for the weather. with temps from KBIL W a bit warmer than they were today.
with slick conditions expected on area roadways as snowfall is expected to rapidly melt on the warmer surfaces. The only other concern in the short term was freezing temperatures and the potential for a freeze overnight tonight.
231 PM CDT Sun Oct 31 2021 The cold front an any associated cloud cover is now well east of the area as of 1 PM, and the expected sunny, gusty afternoon is taking place. In any case, this is just the first of several nights, that pretty much will end the growing season, and we can hopefully stop headlining low temperatures after Monday night as we enter high confidence lows well below freezing. Much of the region is going to fall under northwesterly-northerly upper level flow, as a ridge continues to build over the west and a slow moving trough moves east through the week. This flow is reflected all the way down to the low levels, which means it is looking to stay a bit on the cool side, with little to no warm/moisture advection into the area.
317 PM EDT Sun Oct 31 2021 Synopsis/Discussion - Cold front passage today - Colder week ahead with occasional showers -- Cold front passage bring windy with showers Sunday -- An increase of clouds in the latest visible satellite along with the shift to gusty northwesterly winds are indications of the cold front moving Through southwest Michigan this afternoon. The influx of cold air all stems from a large upper level low that is situated just south of Hudson Bay and will be moving to the north east. As this low rotates, a number of upper level troughs will move through the Great Lakes bringing chances for precipitation. While the first few will be through Northern Michigan, the longest trough will extend down into Illinois and bring mid to low level moisture through central and southwest Michigan.
Temps today will be in upper 60s to low 70s this afternoon with overnight lows in the low 50s along the coast and upper 40s inland. Monday's high temperatures will be in the low 70s with mostly clear skies.
1250 PM CDT Sun Oct 31 2021 Message of the Day - Today (Halloween) will be mostly sunny by the afternoon with high temperatures in the low to mid 50s. Discussion The dry cold front has been making its way through our area overnight, with it currently (3 AM) sitting from Butler, MO to about Moberly, MO. For tricker treaters this afternoon and evening, temperatures will start off in the low to mid 50s and then drop to the mid to upper 40s by sunset. Below normal temperatures will stick around for the week thanks to low pressure over northeast Canada and its very little movement. The multiple nights with low temperatures near or below freezing could very well lead to the end of this year's growing season.
A few light sprinkles, drizzle or showers still possible across the higher elevations of east Tennessee and southwest Virginia as moisture gets squeezed out of the clouds crossing the southern Appalachians for the next few hours.
A relatively dry pattern will continue tonight into Monday as a fairly weak westerly flow aloft prevails across the Western High Plains while a much drier air mass continues to dominate in the lower levels. Despite increasing cloud cover, expect lows down into the lower/mid 30s(F) by early Monday morning. Look for highs only up into the 40s(F) across central and portions of southwest Kansas with the lower 50s(F) possible in extreme southwest Kansas.
Temperatures around to a bit above seasonal norms are expected, topping out in the low to mid 70s over the forecast area.
Currently high pressure is situated from southern Alberta and saskatchewan southeast into eastern Montana and the western Dakotas. Tonight, a lobe of energy will track southeast through the mean trough, keeping the cold air over western and central ND. Monday should be a little cooler than today with more clouds northwest and central.
