One shower moved across portions of the Lower Keys and brought quite a bit of rain in a short amount of time. Thereafter the front will gradually begin to lift back northward as a warm front allowing for deeply southerly winds to return.
558 AM CDT Mon Oct 9 2023 (Today through Tuesday afternoon) A large upper trough over the Great Lakes keeps us under northwesterly flow aloft today, so dry conditions with clear skies and light winds should hold.
327 AM PDT Mon Oct 9 2023 Significantly cooler temperatures with the potential for rain move in early this week. Drier and a little warmer mid-week, with breezy north to northeast winds developing. This system will bring much cooler temperatures for today across the area as well as the chance for some rain as the weakening front moves inland. The highest potential for rain is over the northern Coastal Range and the northern Sacramento Valley. The highest totals are focused over the mountains of Shasta County.
(Today and tonight) A weak cold front will stall across OK by mid day, keeping temps slightly cooler across northern OK this afternoon (low 80s compared to upper 80s south). By tonight, surface winds will slowly become more southeasterly and a warm front will begin to lift northward across the Red River.
717 AM EDT Mon Oct 9 2023 Little to discuss in terms of sensible weather today and tonight as high pressure extends eastward and a very dry airmass settles over the region. Due to the high clouds, this mornings lows are likely to stay a few degrees above the daily records. However, lows will trend a few degrees warmer than this morning. Cool and dry conditions expected to continue but a temperatures will warm as high pressure overhead begins to lift towards the northeast through day and into the night. An area of low pressure over the western Gulf of Mexico will be begin to move towards the east/northeast.
221 AM PDT Mon Oct 9 2023 Our persistent ridge will weaken and push inland, with a vigorous trough moving inland from the northwest behind it. This will bring cooler and windier conditions with a deeper marine layer through the middle of the week.
A cold front remains stretched across south Florida this morning. Temperatures will be slow to warm under mostly cloudy skies topping out only in the low 80's this afternoon. A frontal boundary has settled in over south Florida allowing for cooler, rain-free conditions and northeast winds around 10-15 knots to persist over the eastern gulf waters for the next couple of days.
618 AM CDT Mon Oct 9 2023 (Today through Tuesday) Surface observations this morning show much warmer temperatures versus this time yesterday with current readings in the 40s to low 50s. Highs will also be much warmer today than yesterday thanks to gusty south winds, with highs in the mid 60s on the Plateau and low to mid 70s elsewhere. Tomorrow looks dry and even warmer than today as upper ridging begins to build northward from the Gulf Coast, with highs in the upper 60s to upper 70s.
602 AM CDT Mon Oct 9 2023 (Today and tonight) Our streak of splendid fall weather continues underneath confluent upper flow downstream of a ridge along the Rockies. Up to 30 meters worth of 24-hour 500 mb height falls are forecast by this evening as the ridge flattens while moving over the region. Unfortunately, such paltry moisture throughout the column should keep all but a few high- based cumulus from developing this afternoon, mainly in our W-NW zones near a low-level thermal ridge/axis of deeper mixing. Elsewhere, a weak backdoor front will be found sagging into our northeastern counties later this morning before lee troughing in NM encourages light southerly breezes across the board for the remainder of the day.
553 AM CDT Mon Oct 9 2023 Key Points: - Cooler day today before a warming trend during the early week.
829 AM MDT Mon Oct 9 2023 Strong high pressure aloft will bring warm & dry conditions today, with high temps in the mid 70s to lower 80s for most. JKL Warm temperatures with mostly clear skies will persist today as the powerful ridge of high pressures axis shifts right over our region. By tonight, low pressure is expected to push onto the Pac NW coast, and then into the inter mountain west on Tuesday. So while Tuesday will again see above normal temps in our area (mainly 70s), the upper ridge will be breaking down.
Weak frontal boundary has progressed into south Florida leaving cooler/drier conditions in its wake. Weak high pressure is centered north of central FL. A weaker pressure gradient in place today with the former frontal boundary stalled across south FL and weak high pressure to the north. Considerable (mid-high level) cloudiness continues behind most recent cold front now across south FL. Weak high pressure to the north.
604 AM CDT Mon Oct 9 2023 (Today) A weak cold front currently near the Kansas/Oklahoma border will continue to sag south across much of the area today before stalling out near the Red River this evening.
953 AM EDT Mon Oct 9 2023 High pressure will remain in control through the rest of the work week. As the high expands eastward flow over our area will back southwesterly, helping to usher in some warmer temps and a bit more moisture. Temps rebound into the upper-70s/low-80s tomorrow as ENC remains under high pressure and slightly stronger SW flow.
Dewpoints in Collier County are in the lower 60s, the lower 70s across Miami-Dade, and mid 70s across the Keys. Weak high pressure sliding across the northern Gulf interacting with the frontal boundary will result in gentle northeast to east breezes through Tuesday.
612 AM CDT Mon Oct 9 2023 (Today and tonight) A weak cold front will stall across OK by mid day, keeping temps slightly cooler across northern OK this afternoon (low 80s compared to upper 80s south). By tonight, surface winds will slowly become more southeasterly and a warm front will begin to lift northward across the Red River.
716 AM EDT Mon Oct 9 2023 Cool high pressure will continue to ridge in from the west through Tuesday.
(Today through Tuesday) High pressure currently across southern/southeast TX will begin to shift eastward across the northern GOMEX today. By Tuesday, the high center should be across far south GA/north FL.
642 AM CDT Mon Oct 9 2023 (Today and tonight) Slightly warmer again today with highs in the 80s, as weak zonal flow aloft and a weak lee-side trough are established across the area today.
-There is a very high probability for freezing temperatures overnight tonight through Tuesday morning. If the low retrogrades further west, it is possible that areas in Lake of the Woods/Beltrami don't get to freezing. Regardless, expect at least frost Tuesday morning, with a very high chance (80%) of seeing freezing temperatures. The upper flow pattern will continue to be dominated by ridging to the west and the retrograding low.
An approaching cold front will bring cooler temperatures, overcast skies and some rain today. Thu-Fri will be dry and return to near normal temperatures before the next cold front arrives this weekend.
Key Points: - Strong low pressure system approaches mid to late week, bringing gusty winds and multiple shower/thunderstorm chances.
526 AM MDT Mon Oct 9 2023 *** Glasgow radar remains down due to hardware upgrade and replacement until roughly October 16th *** Upper ridge over the high plains will keep dry and warm weather in the region, with temperatures remaining well above normal through Tuesday. Ridge begins to break down with Pacific upper low moving toward the Pacific Northwest Tuesday night. Lee trof over Montana will start to see cyclogenesis along the Wyoming border, with moisture spreading across the divide.
A large trough and two associated cold fronts will impact the region today through Tuesday with rain, gusty southerly winds and much cooler daytime temperatures.
Highs today will range from the lower 70s along I-70 to the upper 70s in extreme southwest Kansas.
1258 PM CDT Mon Oct 9 2023 (Today and tonight) Slightly warmer again today with highs in the 80s, as weak zonal flow aloft and a weak lee-side trough are established across the area today.
Most areas will bottom out in the 50s, but a few of our more urban locations may only reach the lower 60s as cirrus clouds are expected to gradually increase overnight through Tuesday morning. The increasing high clouds will stick around through the day on Tuesday, slightly limiting high temperatures which should still climb into the lower to mid 80s areawide despite the expanding cirrus canopy. With the additional cloud cover expected, overnight temperatures will only drop back into the lower to mid 60s.
1247 PM CDT Mon Oct 9 2023 (Today and tonight) A weak cold front will stall across OK by mid day, keeping temps slightly cooler across northern OK this afternoon (low 80s compared to upper 80s south). By tonight, surface winds will slowly become more southeasterly and a warm front will begin to lift northward across the Red River.
Temps overall though are starting to rise as high pressure slides into our area by Tuesday ahead of the gulf low later in the week.
The broad cyclone flow aloft at 500 mb and 250 mb will gradually become more zonal through tonight causing some heights rises, especially at 250 mb as broad upper ridging develops over the northern GOMEX.
325 PM CDT Mon Oct 9 2023 Current surface analysis places high pressure stretching across Manitoba through eastern North Dakota, with modest trough to the lee of the Rockies. Upper level analysis places broad deep low just to the south of James Bay along the Ontario/Quebec border, with a narrow ridge over eastern Montana into Saskatchewan. Rather quiet weather remains over our area, though some cumulus have formed over eastern portions of our area in very broad cyclonic flow on the back side of the aforementioned upper low.
1220 PM CDT Mon Oct 9 2023 (Today through Tuesday afternoon) A large upper trough over the Great Lakes keeps us under northwesterly flow aloft today, so dry conditions with clear skies and light winds should hold.
345 PM EDT Mon Oct 9 2023 Short Term/Marine The upper low across SE Canada continues to influence weather across the Great Lakes in the short term.
209 PM CDT Mon Oct 9 2023 Key Messages: * Another couple days of dry/quiet weather A large closed off upper low over southeast Canada will act like a flow pattern block for a couple days over the CONUS.
128 PM EDT Mon Oct 9 2023 High pressure will remain in control through the rest of the work week. As the high expands eastward flow over our area will back southwesterly, helping to usher in some warmer temps and a bit more moisture. Temps rebound into the upper-70s/low-80s tomorrow as ENC remains under high pressure and slightly stronger SW flow.
Highs will range from the mid 80s in the Big Country- where less cloud cover is expected- to the mid to upper 70s across our southern counties where thicker cloud cover will keep temperatures a little cooler.
247 PM CDT Mon Oct 9 2023 Key Messages: *Frost Advisory in effect late tonight into early Tuesday AM for most of the outlook area except the far SE portion where forecast temperatures are a bit warmer. *Areas of frost/near freezing temperatures are possible in the north Tuesday night. Low temps are expected to drop into the low to mid 30s generally along and northwest of a line from Memphis, MO to Princeton, IL. Low temps in the low/mid 30s north of highway 30 could lead to another round of frost.
Most locations can expect afternoon temperatures climbing into the lower 80s this afternoon. Tonight temperatures can be expected to be a touch warmer than this morning with continued moisture return. Isolated afternoon showers and thunderstorms are expected to develop over the higher elevations and slide east through the afternoon and early evening. Overnight temperatures should be a touch warmer again as moisture continues to flow back into the region.
324 PM EDT Mon Oct 9 2023 A large and nearly stationary upper low will be located between James Bay and Georgian Bay over the next 36 to 48 hours before drifting gradually east to Nova Scotia late this week.
Tonight, a scattered cloud deck is expected to move in after sunset and will keep overnight lows in the low to mid 50s save for elevated areas where lows will be in the upper 40s.
The first feature on satellite imagery is a trough of low pressure arriving onshore in northern British Columbia. Despite its distance from the Northern Rockies, it is pushing a cold front across the Pacific Northwest this afternoon. This system will be pushing moisture into the Northern Rockies ahead of the actual low pressure center.
303 PM CDT Mon Oct 9 2023 Key Messages: -Freezing temperatures are expected to overspread much of the region tonight, with many locations potentially dropping into the mid-20s. For Tuesday, temperatures climb above freezing relatively quickly around sunrise, with daytime highs expected to reach the upper 40s to lower 50s.
A weak cold front is expected to come through and result in slightly cooler air tonight with lows starting in the upper 40s. By the end of the week, another cold front will bring in rain showers and perhaps a thunderstorm throughout the MidSouth. Following the cold front, cooler temperatures and drier air conditions are expected into the weekend.
Returning S/SW winds will allow for a warmer day today as compared to the past few days with high temperatures ranging through the 80s this afternoon.
(This afternoon through Tuesday) A massive upper low is centered over Quebec and Ontario, but expansiveness of the trough extends as far south as the Gulf Coast where deep westerly flow will be in place over Central Alabama through tomorrow. At the surface, high pressure extends from off the Mid-Atlantic coast into the Gulf of Mexico which is producing more of a southwesterly component in the boundary layer flow across the area. This will drive a slight warming trend as highs moderate from upper 70s to near 80F today to most locations hitting the lower to mid 80s tomorrow. Even with the high clouds temperatures will still fall into the lower 50s tonight.
A closed upper low spins north of the Great Lakes over the Ontario/Quebec border with broad upper troughing encompassing the eastern half of the CONUS. On the surface a dry cold front sits over south Florida and weak high pressure sits along the northern gulf coast. Some much cooler and drier air has settled in over the Florida peninsula and will persist through Tuesday morning.
The weak cold front that entered our area earlier today will begin to lift back north as a warm front later tonight. The warm front will then continue northward through the day on Tuesday, with highs warming into the mid to upper 80s areawide tomorrow afternoon.
The dry air and linger high pressure in the region tonight should still allow for some decent radiational cooling overnight, with tonight's lows expected to be mostly in the lower 50s - or about 5-8 degrees below normal. Later in the week, another cold front is progged to pass from the west and once again usher in very dry air and potentially some gusty post frontal winds.
430 PM EDT Mon Oct 9 2023 With a large upper level low spinning over southeast Canada over the next few days, cool and cloudy conditions continue through mid week. A large upper low has stalled over Southeast Canada just north of the Great Lakes. The low retrograded farther west than what models initially had so winds through the boundary layer are more westerly to even a little southwesterly so that has helped shift any lake effect precipitation well north of our area. Chances were kept though in the Southern Tug Hill though if the low continues its slow trek west than the chances of precip may even need to be removed there. Tomorrow night there is less wind though day time highs will get to be about 5 degrees warmer so lows will likely be similar to tonight.
241 PM MDT Mon Oct 9 2023 *** Glasgow radar remains down due to hardware upgrade and replacement until roughly October 16th *** Today through Tuesday, a ridge of high pressure will remain in control across our region, keeping conditions warm and dry. Forecast confidence is increasing for a significant cold front pushing this direction from a large and strong trough of low pressure from Washington State and Oregon.
(The rest of today ) A weak cold front continues settling south across northeast Oklahoma and is roughly along the I-44 corridor at this time. Current temperatures are running a few degrees warmer than this time yesterday with the greatest increase across southeast Oklahoma and northwest Arkansas.
1232 PM CDT Mon Oct 9 2023 (The rest of today ) A weak cold front continues settling south across northeast Oklahoma and is roughly along the I-44 corridor at this time. Current temperatures are running a few degrees warmer than this time yesterday with the greatest increase across southeast Oklahoma and northwest Arkansas.
There's not a lot of moisture to work with east of the higher terrain, across the plains of NM into West Texas, with dewpoints only in the 30s and T-Td spreads of 40-50F. A modest LLJ tonight will gradually improve the low-level moisture levels across the area which should set the stage for slightly better precipitation chances for western areas Tuesday afternoon and evening.
A trailing, moisture-starved cold front will settle south across southern VA and NC late Tue through early Wed. A deep, occlude cyclone over the Ontario/Quebec border just south of James Bay will maintain cyclonic flow and anomalously low heights across the Great Lakes and middle Atlantic. At the surface, a weakening and modifying high pressure will continue to extend across the South Atlantic and Gulf coast states. An occluded cyclone near the srn tip of James Bay will fill and weaken and promote rising heights and gradually relaxing cyclonic flow across the middle Atlantic, while also allowing a strong srn stream jet to bulge nwd and across the mid-South and srn middle Atlantic.
230 PM CDT Mon Oct 9 2023 Key Messages: - Widespread frost tonight, freezing temps for a few.
1102 AM EDT Mon Oct 9 2023 Only changes made to the forecast were to account for temperature trends this morning being a tad cooler. (Today through Tuesday) High pressure currently across southern/southeast TX will begin to shift eastward across the northern GOMEX today. By Tuesday, the high center should be across far south GA/north FL.
130 PM PDT Mon Oct 9 2023 Cooler through mid-week with a deepening marine layer.
Early Season Snow Likely Later This Week in the Higher Potent NE Pac upper trough digging into the Pac NW as the stubborn Hudson Bay low retrogrades slowly west. This will eventually support a vigorous wrapped up sfc cyclone by mid to late this week, with local heavy rains and some snow in the higher elevations of the region. Pac NW trough will push into the central Rockies Wed, supporting pos theta-e adv over the FA.
/Tonight through Monday/ FORECAST HIGHLIGHTS: --Widespread frost, some areas near to just below freezing late tonight into Tuesday morning.
- High pressure, clear skies, and slightly warmer temps tomorrow. The clipper low pressure system is located in central Kentucky. High pressure will build into the region allowing for continued clear skies and light winds out of the northwest. High pressure will remain over the region leading to clear skies and warmer temperatures.
1253 PM CDT Mon Oct 9 2023 Key Points: - Cooler day today before a warming trend during the early week.
Discussion: One more day of widespread pleasant weather as ridging remains over the state. By late Tuesday morning, the main trough will begin to push in. By Tuesday evening precipitation chances will become more widespread as heights fall further under the progressing trough.
WV imagery indicates a northwest flow aloft prevailing across the Western High Plains downstream of a weakening upper level ridge across the Intermountain West. Near the surface, a weak cold front extends from eastern Colorado southeast into southwest Oklahoma. This will help draw warmer air into western Kansas, pushing H85 temperatures up into the upper teens(C) in central Kansas to up near 25C in extreme southwest Kansas.
1156 AM CDT Mon Oct 9 2023 (Today through Tuesday) Surface observations this morning show much warmer temperatures versus this time yesterday with current readings in the 40s to low 50s. Highs will also be much warmer today than yesterday thanks to gusty south winds, with highs in the mid 60s on the Plateau and low to mid 70s elsewhere. Tomorrow looks dry and even warmer than today as upper ridging begins to build northward from the Gulf Coast, with highs in the upper 60s to upper 70s.
Above normal temperatures will return to the area through the middle of the week, with highs back into the low to mid 80s across the area.
A Pacific cold front with cross the area this afternoon and tonight, with scattered showers and isolated thunderstorms in southeast Oregon this afternoon spreading into southwest Idaho this evening, along with gusty southwest to west winds 15-25 mph in southeast Oregon and the southwest Idaho highlands. Southwest Idaho will be warm again ahead of the front, with temperatures reaching the lower 80s in the valleys. Highs on Tuesday will be around 20 degrees cooler, with showers becoming widespread Tuesday afternoon. Showers and isolated thunderstorms will cross the area with a cold front, starting in southeast Oregon this afternoon and southwest Idaho this evening.
-Much cooler weather returns by this weekend. Flow aloft remains from the northwest as the region is positioned on the southwestern edge of an expansive low pressure system centered south of Hudson Bay. Isentropic ascent as a warm front approaches from the south could result in scattered rain showers developing tomorrow afternoon and evening.
125 PM CDT Mon Oct 9 2023 We'll see a recently passed surface cold front continue to sag southward and eastward in the near term, as high pressure builds across the Mid to Upper Mississippi Valley. This occurs as the front's parent upper cyclone is closed and rotating in nearly stationary fashion over the Great Lakes. This helps return flow southerlies establish here, and what ensues is a northward lifting (now) warm front.
309 PM EDT Mon Oct 9 2023 A large and nearly stationary upper low will be located between James Bay and Georgian Bay over the next 36 to 48 hours before drifting gradually east to Nova Scotia late this week.
920 AM PDT Mon Oct 9 2023 Cooler through mid-week with a deepening marine layer.
1241 PM CDT Mon Oct 9 2023 (Today and tonight) Our streak of splendid fall weather continues underneath confluent upper flow downstream of a ridge along the Rockies. Up to 30 meters worth of 24-hour 500 mb height falls are forecast by this evening as the ridge flattens while moving over the region. Unfortunately, such paltry moisture throughout the column should keep all but a few high- based cumulus from developing this afternoon, mainly in our W-NW zones near a low-level thermal ridge/axis of deeper mixing. Elsewhere, a weak backdoor front will be found sagging into our northeastern counties later this morning before lee troughing in NM encourages light southerly breezes across the board for the remainder of the day.
