Highs today will range from the low to mid 70s in the north to right around 80 degrees along the Rio Grande and across the Rio Grande Plains. High clouds will continue through the evening, shifting south overnight as the aforementioned high pressure settles into the area. Overnight lows will generally range from the low 50s to low 60s.
324 PM CDT Sat Oct 7 2023 A trough is positioned over the Great Lakes into the southeast CONUS while a ridge stretches from the Southern Plains to western Canada. After a cool start to the day, high pressure remains over the region with clear skies and fall like temperatures as afternoon values have risen into the 60s. Highlights: Warmer & dry Changes: Slight upward bump in temps Sunday It will not be as cool tonight as last night with low temperatures in the lower 40s instead.
The tightening pressure gradient over PA is producing breezy conditions and ushering in noticeably cooler air with dewpoints in the 30s. Typical autumnal post frontal regime in effect on Sunday thanks to cut off upper low over SW Ontario funneling cool air over the warmer GLAKS.
1142 AM CDT Sat Oct 7 2023 (Today through Sunday) The deterministic NAM/GFS/ECMWF predict the upper level low/associated trough to develop/persist over the eastern CONUS during the period while an upper N-S ridge axis persists over the Rockies.
Lows will be in the low to mid 40s areawide. Tomorrow will be much of the same as this mid level trough will continue to hover cool and dry air over us, keeping conditions pretty quiet and comfortable. High temperatures will be in the low to mid 70s, with much calmer winds than today.
215 PM MDT Sat Oct 7 2023 A pleasant, sunny fall day is ongoing as ridging moves over the area. Not much change is expected on Sunday, though it will be just a little warmer as the ridge axis passes through; most of the area will warm to around or just above 70.
With those southerly winds in place and much warmer mid-level temperatures, highs on Sunday will likely be 10 to 15 degrees warmer than today, with readings in the upper 70s to mid 80s across the area.
An amplified ridge of high pressure will shift east through the region tonight and east of the Wyoming divide Sunday as the next upstream storm system begins to take shape off the NW coast.
138 PM MDT Sat Oct 7 2023 Satellite imagery continues to show nearly cloud free skies under the large ridge of high pressure over the western CONUS. Overnight lows will be slightly warmer as well with readings between 35 to 45F common.
An upper level trough over the Great Lakes Region will continue to push a dry cold front into the Florida Peninsula this afternoon and evening. Isolated to scattered showers and a few storms will be possible ahead of the front this afternoon, with the highest chances south of Interstate 4, but in general coverage should remain limited.
Upper-air pattern this afternoon continues to feature northwest flow aloft with a large trough covering most of the eastern CONUS. For Sunday, temperatures will climb into the 70s across the region and be slightly warmer than what we have seen today. I did stick with the idea of the overnight shift to carry on with the slightly warmer temperatures than what NBM was spitting out due to the dry air we have in place. Low temperatures Sunday night will fall into the lower 50s across the region.
930 AM PDT Sat Oct 7 2023 A West Coast ridge will bring sunny, hot days this weekend except near the coast where a shallow marine layer will bring cooler weather and areas of dense morning fog.
A large ridge over the western US will keep our weather quiet tonight with lows generally in the 30s. A weak low will move southward out of southern Canada and into the upper Mississippi valley, pushing a dry cold front through Nebraska tomorrow.
Afterwards, a Pacific trough will bring cool air and breezy conditions to the area.
2) A cold front moves through Sunday turning our winds northwesterly and gusty for Sunday afternoon. Continued WAA into the overnight will keep our lows tonight well above freezing, upper 30s to mid 40s. Model trends have been holding steady to slightly warmer for Sunday. Despite CAA behind the cold front, the 850 mb temperatures hold in the 4 to 10 degrees C range, with the GFS being a bit warmer than the others. Efficient mixing and mostly sunny skies will help us warm into the low to upper 60s. The I-29 corridor will likely see the highest gusts with some approaching 25 mph.
1237 PM CDT Sat Oct 7 2023 Key messages: 1) Cool and dry weather can be expected today and tonight due to high pressure over the Great Plains. This high will drift southeast into the lower Mississippi Valley through tonight. 2) Wind will turn to the west southwest on Sunday ahead of another weak low pressure system, causing temperatures to warm back near normal in the upper 60s to low 70s.
(This afternoon through Sunday night) The weather pattern remains quiet as the large upper trough continues to slide east and an upper level ridge takes its place across our region.
Dry weather and above average temperatures continue through the weekend as a high pressure remains over the state.
-Cooler temps tonight in northwest Minnesota, with warmer temperatures west of the Red River. Our best chances of seeing freezing temperatures overnight will be in northwestern Minnesota, where isolated spots could fall into the lower 30s. As a trough continues east across the Great Lakes, it will come to a stop right south of the Hudson Bay. Over our area, split jet stream flow will make for quasi-ridging in the upper levels to our south through mid-week, before another trough makes its way through near the end of the week.
Afterwards, a Pacific trough will bring cool air and breezy conditions to the area. Low impact weather will persist tonight as high pressure remains over the region. Overnight low temperatures will be a few degrees warmer than last night in most locations.
626 PM CDT Sat Oct 7 2023 A trough is positioned over the Great Lakes into the southeast CONUS while a ridge stretches from the Southern Plains to western Canada. After a cool start to the day, high pressure remains over the region with clear skies and fall like temperatures as afternoon values have risen into the 60s. Highlights: Warmer & dry Changes: Slight upward bump in temps Sunday It will not be as cool tonight as last night with low temperatures in the lower 40s instead.
711 PM EDT Sat Oct 7 2023 Aviation Upper low continues to bring diurnally-enhanced lake effect rain showers through the short term.
625 PM CDT Sat Oct 7 2023 (This afternoon through Sunday night) The weather pattern remains quiet as the large upper trough continues to slide east and an upper level ridge takes its place across our region.
With the high centered closer to Southeast Oklahoma tonight. temps across the southern portion of the CWA look to be slightly cooler tonight compared to last night. The upper level low will shift east Sunday and upper level heights will begin to rise.
635 PM CDT Sat Oct 7 2023 (Tonight) By tonight, high pressure centered over the Plains will shift eastward and push a low sitting over the Great Lakes off to the northeast.
Upper low continues to bring diurnally-enhanced lake effect rain showers through the short term.
This runs ~13 degrees cooler than normal with seasonal low values of 55 degrees at KMSL and KHSV.
513 PM MDT Sat Oct 7 2023 A pleasant, sunny fall day is ongoing as ridging moves over the area. Not much change is expected on Sunday, though it will be just a little warmer as the ridge axis passes through; most of the area will warm to around or just above 70.
755 PM EDT Sat Oct 7 2023 An upper level low pressure system brings cool temperatures and times of rain and cloudiness into the next work week.
High pressure will track across Utah through the weekend, into the start of the week.
Temperatures outside of the current Frost Advisory have fallen into the lower to middle 30s already; therefore, will expand the Frost Advisory to include the rest of north-central Wisconsin and pull the start time to the current time. As the clouds spread eastwards, moisture in the lower level will increase. There is still some uncertainty in low temperatures across the north where the cold low level winds will be moving across the relative warmer waters of Lake Superior which would at least bring cloudiness into northern Wisconsin.
758 PM EDT Sat Oct 7 2023 Overnight lows will be the coldest the region has seen for quite some time, with temperatures in the lower 40s expected across the Midlands and CSRA tonight and Sunday night. A cold front has moved offshore with cooler and drier air moving into the forecast area. The deep trough over the eastern portion of the CONUS will bring a stretch of unseasonably cool weather to the region along with dry conditions.
While broad troughing spans the eastern United States through the mid and upper levels, the flow at our latitude is mostly zonal.
Surface winds: East to southeast 5-15 kt, with winds across southeast Oregon and in the higher terrain becoming southwest Sunday afternoon with gusts 15-25 mph.
Quiet evening continues with much milder temperatures this evening (around 20 degrees warmer) compared to last evening, thanks to a warm front which pushes through the past several hours. Presently, a west CONUS ridge is gradually trying to slide eastward resulting in WAA over the state. An associated warm frontal boundary off said low is presently analyzed north to south through central ND, and will continue to progress eastward across the forecast area through the day today. Trailing cold frontal boundary tonight should have little impact other than a wind shift and lows dropping back into the mid to upper 30s for most locations. Sunday will see slightly cooler highs with temperatures ranging from the low 50s in the north central to the low 60s, although a few locations in the southwest may reach the mid 60s.
This start to an overall warming trend can be attributed to high pressure building back over the area and increased south to southwesterly winds today. Even though there will be decent radiational cooling under mostly clear skies again tonight across much of West Central Texas, overnight lows tonight will be slightly warmer and reach into the low 50s to low 60s.
122 AM EDT Sun Oct 8 2023 A cold front will pass to the east this evening. Low pressure will deepen across eastern Canada tonight into Sunday, then remaining nearly stationary and weakening through mid week. It will also turn much cooler through the night with lows generally in the 40s to around 50. This will be about 10-15 degrees cooler than the previous night. This low will then become stationary and weaken through the first half of the upcoming week.
Will see this gradually slide to the southeast over night with temps in the low to mid 30s to near 40 where clouds linger. -Cooler temps tonight in northwest Minnesota, with warmer temperatures west of the Red River. Our best chances of seeing freezing temperatures overnight will be in northwestern Minnesota, where isolated spots could fall into the lower 30s. As a trough continues east across the Great Lakes, it will come to a stop right south of the Hudson Bay. Over our area, split jet stream flow will make for quasi-ridging in the upper levels to our south through mid-week, before another trough makes its way through near the end of the week.
200 AM CDT Sun Oct 8 2023 Broad troughing sits over most of the eastern third of the country with a little reinforcing pinwheel low moving across the northeastern part of the CWA early this morning with a few transient high clouds.
(Today and tonight) Clear skies and southwest surface winds will lead to temperatures over 10 degrees warmer today compared to yesterday with highs ranging from the upper 70s to the mid-80s.
218 AM MDT Sun Oct 8 2023 Satellite imagery continued to show a nearly cloud free sky under a large ridge of high pressure dominating over the western CONUS.
1118 PM EDT Sat Oct 7 2023 A cold front will pass to the east this evening. Low pressure will deepen across eastern Canada tonight into Sunday, then remaining nearly stationary and weakening through mid week. It will also turn much cooler through the night with lows generally in the 40s to around 50. This will be about 10-15 degrees cooler than the previous night. This low will then become stationary and weaken through the first half of the upcoming week.
A warming trend is expected from late Mon into Tue ahead of the next cold front. This cold front is expected to remain dry as it passes thru early Wed, with a return to near normal temperatures thru Fri. Rain chances will increase towards the end of the week as the next front and area of low pressure approach the area. Expansive cutoff upper low across SE Canada to encompass basically the U. Embedded mid-level s/w trofs rotating around this upper low to remain north of the FA along with any mid or upper level moisture accompanying them. Will remain dry in the low levels keeping fog potential a non-issue tonight.
438 AM EDT Sun Oct 8 2023 Low pressure lifts northwest into Quebec today.
223 AM CDT Sun Oct 8 2023 Key Message: Today will be a pleasant day with partly to mostly cloud skies, and somewhat warmer temperatures. Highs today could be a good bit warmer than yesterday, but with cloud cover, prefer a more conservative approach of the NBM with upper 50s northeast to upper 60s southwest.
1201 AM CDT Sun Oct 8 2023 A trough is positioned over the Great Lakes into the southeast CONUS while a ridge stretches from the Southern Plains to western Canada. After a cool start to the day, high pressure remains over the region with clear skies and fall like temperatures as afternoon values have risen into the 60s. Highlights: Warmer & dry Changes: Slight upward bump in temps Sunday It will not be as cool tonight as last night with low temperatures in the lower 40s instead.
255 AM MDT Sun Oct 8 2023 Concerns remain slim to none over the next 36 hours as high pressure will continue to bring some delightful fall weather with mild days, cool nights and little cloud cover.
A somewhat blustery and cool end to the weekend is in store due to a large upper low centered over southern Quebec. With the upper low to our northwest, scattered showers will continue throughout the day, especially areas downwind of Lake Ontario and the western slopes of the Adirondacks. Daytime high temperatures will generally be in the mid to upper 50s, with the higher terrain struggling to make it out of the 40s. Overnight lows will continue to be quite cool, as 850mb temperatures below 0 C will make for temperatures in the low 30s to mid 40s, with slightly warmer temperatures near Lake Champlain.
(Today) A warmer day is on the way for eastern Oklahoma and western Arkansas as high pressure currently centered over north-central Texas shifts to the east allowing for the return of a south-southwesterly low level flow.
1257 AM EDT Sun Oct 8 2023 Latest IR satellite loop was showing some thicker mid and high clouds spreading southeast across central Indiana within fast northwest flow aloft around aN eastern Great Lakes upper low and associated with several impulses within the flow. An upper trough is exiting and becoming a large cut off low throughout the short term. Models show this low centering itself over the Hudson Bay as remnants from post-tropical storm Philippe gets absorbed into the upper system. Some light rain will be possible late Sunday, but confidence remains on the low end given the dry conditions in place.
1152 PM CDT Sat Oct 7 2023 (This afternoon through Sunday night) The weather pattern remains quiet as the large upper trough continues to slide east and an upper level ridge takes its place across our region.
227 AM MDT Sun Oct 8 2023 *** Glasgow radar remains down due to hardware upgrade and replacement until roughly October 16th *** MORNING DISCUSSION: Synoptic Setup: Forecast begins with a large ridge over the western half of Canada and the CONUS with the axis running north through the Intermountain West and into Alberta. Father west another trough is moving into the Gulf of Alaska and just off the coast of the Pacific Northwest.
Upper low spins over the Great Lakes with associated upper trough over the eastern 1/2 of the U. Cooler and drier but shallow airmass will hold over the region into early week while abundant upper moisture continues to stream over the Gulf for cool dry low levels and thick cirrus shield overhead.
912 PM PDT Sat Oct 7 2023 A West Coast ridge will bring another hot day to the valleys and deserts Sunday, while a shallow marine layer keeps it cooler along the coast, with more fog in the morning.
339 AM EDT Sun Oct 8 2023 Significantly cooler, Fall temperatures and a gusty wind will combine to bring a November-like chill to Central PA to close out the first full weekend of October.
1022 PM CDT Sat Oct 7 2023 KEY MESSAGES: - A cold front moves through Sunday turning our winds northwesterly and gusty for Sunday afternoon. Continued WAA into the overnight will keep our lows tonight well above freezing, upper 30s to mid 40s. Model trends have been holding steady to slightly warmer for Sunday. Despite CAA behind the cold front, the 850 mb temperatures hold in the 4 to 10 degrees C range, with the GFS being a bit warmer than the others. Efficient mixing and mostly sunny skies will help us warm into the low to upper 60s. The I-29 corridor will likely see the highest gusts with some approaching 25 mph.
Otherwise, temperatures are in the lower 80s with the exception of Big Pine Key, where radiational cooling has allowed for temps to drop into the mid 70s. A cold front analyzed roughly along a line from Sarasota to just north of Melbourne is slowly sliding south across the Florida Peninsula this morning.
Mid level short wave energy will drop down the back side of a broad upper level trough that is in place across the eastern US. Temperatures will remain on the cooler side again today with afternoon highs mostly in the mid to upper 50s.
234 AM MDT Sun Oct 8 2023 The short term forecast period is dominated by high pressure and a dry air mass.
1058 PM MDT Sat Oct 7 2023 A pleasant, sunny fall day is ongoing as ridging moves over the area. Not much change is expected on Sunday, though it will be just a little warmer as the ridge axis passes through; most of the area will warm to around or just above 70.
Upper low currently rotating over the eastern Great Lakes is expected to wobble slightly back to the west during the next 36 hours. Think that not much will change with that today as high pressure builds in from Canada, so highs will be a bit higher from the Red River Valley eastward where readings will climb into the mid to upper 50s.
309 AM EDT Sun Oct 8 2023 A large upper level low pressure system centered over Quebec will bring active weather today.
200 AM PDT Sun Oct 8 2023 A weakening ridge of high pressure over the western part of the country will bring another warm day for lower elevations away from the coast. The marine layer will begin to build through the early part of the work week as a trough pushes into Northern California and the Pacific Northwest. This will bring in cooler weather, along with morning low clouds for coastal and valley areas west of the mountains and stronger mountain and desert winds. Weak ridging will occur for later in the week, where temperatures will be within a few degrees of average.
316 AM CDT Sun Oct 8 2023 Key Points: - Temperatures warm today before another punch of cooler air late this afternoon and evening. Gusty winds (~15-25 MPH) are anticipated ahead of the cooler air's arrival.
After a period of patchy fog this morning, high pressure and fabulous fall weather continues.
Evening water vapor/upper air analysis indicates closed low centered over the Great Lakes with trough axis off to the east. Lows in the low to mid 40s, some 10-15 degrees below normal, are on track. Can't rule out some eastern areas overachieving a few degrees cooler, possibly into the upper 30s in typical cold drainage areas in central-northeast Mississippi. Lows will be in the low to mid 40s areawide. Tomorrow will be much of the same as this mid level trough will continue to hover cool and dry air over us, keeping conditions pretty quiet and comfortable. High temperatures will be in the low to mid 70s, with much calmer winds than today.
228 AM CDT Sun Oct 8 2023 Through tonight: Another dry and seasonably cool day is on tap as strong surface ridging remains anchored across the Deep South.
1033 AM EDT Sun Oct 8 2023 Low pressure lifts northwest into Quebec today.
505 AM EDT Sun Oct 8 2023 Significantly cooler, Fall temperatures and a gusty wind will combine to bring a November-like chill to Central PA to close out the first full weekend of October.
614 AM CDT Sun Oct 8 2023 (Today and tonight) Clear skies and southwest surface winds will lead to temperatures over 10 degrees warmer today compared to yesterday with highs ranging from the upper 70s to the mid-80s.
This southwest surface flow will increase slightly throughout the day as the pressure gradient tightens between the high and lee trough. Skies will remain clear tonight, and some low level moisture advection wrapping around the high will result in an increase in dewpoints into the mid to upper 40s by early morning Monday. This will result in warmer min temps right around average.
1008 AM EDT Sun Oct 8 2023 Significantly cooler, Fall temperatures and a gusty wind will combine to bring a November-like chill to Central PA to close out the first full weekend of October.
622 AM EDT Sun Oct 8 2023 Cold high pressure will build into the area through Monday. Nwly flow will continue through the lower levels supporting dry conditions and cool daytime highs in the mid to upper 60s (~10 degrees below normal). Expect similar overnight lows in the lower 40s (with upper 30s likely at our cooler spots). An upper low will remain quasi-stationary over the northern Great Lakes through late week.
This will advect slightly warmer air back to the area, and expect temperatures to rebound.
A weather system will bring a chance of showers along with cooler temperatures early in the week, then warmer and drier weather returns. Conditions are nearly identical to 24 hours ago as the upper ridge begins to shift to our east.
710 AM EDT Sun Oct 8 2023 Significantly cooler, Fall temperatures and a gusty wind will combine to bring a November-like chill to Central PA to close out the first full weekend of October.
416 AM MDT Sun Oct 8 2023 Concerns remain slim to none over the next 36 hours as high pressure will continue to bring some delightful fall weather with mild days, cool nights and little cloud cover.
611 AM CDT Sun Oct 8 2023 Key Points: - Temperatures warm today before another punch of cooler air late this afternoon and evening. Gusty winds (~15-25 MPH) are anticipated ahead of the cooler air's arrival.
A deep upper low centered over southern Quebec will result in lake enhanced isolated to scattered showers favoring northwest PA with cold northwesterly flow over the relatively warm lake water. Have removed mention of rain/snow in the ridges as there will not be sufficient moisture. Below normal temperatures will continue into the upcoming work week as the mentioned upper low remains nearly stationary over Quebec/Ontario.
Moving into Monday the main forecast concern is precipitation chances associated with a retrograding low-pressure system to our northeast. Monday night the upper low will be overhead which will essentially continue to be the case into mid week. The upper low though will be moving slightly off to the north and east with time, losing a bit of its influence on our area weather.
611 AM CDT Sun Oct 8 2023 (Today) A warmer day is on the way for eastern Oklahoma and western Arkansas as high pressure currently centered over north-central Texas shifts to the east allowing for the return of a south-southwesterly low level flow.
733 AM EDT Sun Oct 8 2023 Low pressure lifts northwest into Quebec today.
- Monday night looks to be the coldest across the area, with the best combination of light winds and clear skies to produce freezing temperatures.
