Cooler and breezier conditions return for Thursday with an incoming disturbance clipping the Four Corners. High pressure builds back up into the region this weekend, resulting in slightly warmer and dry conditions once again. Today will see a downturn in temperatures and an uptick in winds as an area of low pressure skirts the Four Corners area. Temperatures could be around 15 degrees cooler than yesterday and winds could gust up to around 35 mph closest to the center of the storm. Friday will see a return to warmer temperatures and light winds, preceded by what could be the coldest morning of the season thus far.
1056 AM EDT Thu Oct 27 2022 A cooler and more seasonable airmass will build into the region today behind the passage of a cold front. High pressure will bring a period of dry weather which will last through the weekend. The cooler air mass will keep high temperatures today around 50F in most areas, with mid to upper 40s for the higher terrain. Temperatures will fall to near or below freezing for most areas, but a touch warmer near the lakes.
While this boundary is bringing increased chances for rain it is not bringing cooler weather. Temperatures this afternoon will reach into the lower to middle 80s along the Nature Coast and will top out in the upper 80s further south.
High pressure will build in today as the last system moves east out of the area. Morning temperatures Friday look to be well below freezing across the area, mid to upper teens to low twenties in valleys and single digits to low teens in the mountains.
An upper level low is currently centered near the Four Corners region. The better rain chances and higher probability of severe weather will occur late this evening and into the overnight hours as the aforementioned upper level low approaches, resulting in large scale lift. Initially, isolated to scattered showers and thunderstorms are forecast to develop west of our area, along and ahead of a Pacific cold front. This line is forecast to track across the region through the morning hours, with our northern and eastern counties seeing the highest rain chances. On Friday, some wrap around showers, and even a few thunderstorms, are possible as the upper level low exits the area.
201 PM MDT Thu Oct 27 2022 Upper level low that brought the rain and snow to the region will track southeast across the Southern Rockies tonight and across Texas Friday. Upper level ridging builds over Colorado for Friday. Sunny skies and mild temperatures will prevail under the ridge. Friday night, a deep closed upper low will be moving across Northeastern Texas with an upper level ridge of high pressure over Colorado. Over the weekend, a weak upper trough will move across the area with seasonable temperatures expected. Despite the passage of the trough, no precipitation is expected due to a lack of moisture.
(This afternoon through Friday Night) Sprawling high pressure covered most of the eastern U. Fair wx will continue tonight through Friday with seasonable lows tonight and warmer highs for tomorrow. The next significant wx system coming our way is a low pressure over the Four Corners. The low will move out to Texas by Friday evening.
350 PM CDT Thu Oct 27 2022 A narrow swath of clearing and mid level cooling on the north side of an upper level low is occurring across extreme southwestern Kansas this afternoon. Temperatures should bottom out in the lower to mid 40s tonight. Clearing can be expected Friday in the wake of this system, with highs in the lower 60s. Tranquil weather can be expected through Thursday, with upper level ridging developing over the Rockies and moving across the plains and into the Midwest during the week.
213 PM MDT Thu Oct 27 2022 Current WV imagery depicts trough digging into the desert southwest with a closed low developing over the Four Corners region. Split flow develops as the trough digs into the southern US and the upper low meanders through the southern tier of the CONUS.
Ensemble guidance keeps weak ridging over the island chain now through the weekend. Daytime high temperatures will range from the low to mid 80s, and overnight low temperatures will be in the lower 70s.
357 PM EDT Thu Oct 27 2022 High pressure will build northeastward from the Ohio Valley toward New England through the weekend.
305 PM CDT Thu Oct 27 2022 High pressure off to our northeast will keep our region dry through Friday night with a gradual increase in high clouds.
Sprawling high pressure was centered over the Great Lakes with fair wx across most of the eastern states. These clouds are spreading from a deepening trough over the southwest states. This trough will eventually move eastward and bring us some much needed rainfall this weekend.
1152 AM EDT Thu Oct 27 2022 High pressure and drier weather builds in today. Upper level trough moves east while upper ridging takes its place overhead. Dry conditons persist into the next period as high pressure builds.
High pressure aloft along the coast will pass over us Friday with warming aloft greater than warming at the surface, resulting in a mild inversion.
349 PM EDT Thu Oct 27 2022 Temperatures will be near normal as modest to strong high pressure fills in over the region through the remainder of the week. High pressure will continue to build down from the north through Friday as the center shifts east from the Great Lakes across to the New England coast by late Fri. Weak isentropic lift and onshore flow in the low levels will produce an increase in moisture tonight into Fri. High pressure will ridge into the area from the north during this period, resulting in mainly fair weather.
225 PM EDT Thu Oct 27 2022 Upper air pattern consists of a 500 mb trough in the central Rockies and a trough across western Quebec.
This has included some gustiness at times, but winds/gusts should relax with nightfall as high pressure slides east and low pressure develops/approaches from the southwest. As a developing low pressure system approaches from the southwest Friday night, moistening down the column will begin gradually. It will take it awhile to get close enough, and for the surviving ridge of high pressure along the Eastern Seaboard to loosen its grip enough, for this to manifest into appreciable pops for our FA.
Highs will reach the lower 60s across the Plateau and along the KY border to mid 60s elsewhere.
223 PM CDT Thu Oct 27 2022 Current satellite water vapor imagery shows a very healthy looking upper level low pressure system centered over Colorado/New Mexico moving eastward. Rainfall amounts will be on the lighter side due to the high based nature generally less than a quarter of an inch. Meanwhile an area of more widespread rain will develop and circulate around the main upper low itself.
Cooler and breezier conditions return today with a disturbance clipping the Four Corners. High pressure builds back into the region this weekend, resulting in slightly warmer and dry conditions once again. An area of upper level low pressure has moved into northwestern New Mexico this afternoon. Thanks to a cold front that moved through the area today, temperatures are much cooler than yesterday. Anywhere from 5 degrees cooler to nearly 15 degrees cooler across the northeast. As the low tracks eastward and away from Arizona tonight, expect decreasing winds. High pressure dominates the pattern, resulting in closer to normal high temperatures and light winds. Nearly all of the forecast guidance has some form of a cold trough developing and moving through the southwestern U. About 50-65% of the ensemble membership has a colder and deeper trough that would support accumulating mountain snow.
238 PM EDT Thu Oct 27 2022 High pressure centered over Lower Michigan this afternoon will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
1216 PM EDT Thu Oct 27 2022 A clearing trend is expected today under building high pressure.
1201 PM CDT Thu Oct 27 2022 While we remain under the influence of high pressure following this week's low, we see another trough digging out west today. Flow aloft will become increasingly southwesterly with time today, but at the surface the high moving into the Great Lakes will maintain its influence across our region with a low level easterly flow. The western trough digs further south and east than the last one, cutting off fully over the Red River between Texas and Oklahoma on Friday. The rain associated with it will stay to the southwest near the upper low, and in fact our area will likely see a bit more sunshine with highs more solidly in the 60s.
152 PM EDT Thu Oct 27 2022 High pressure will build northeastward from the Ohio Valley toward New England through the weekend.
318 PM EDT Thu Oct 27 2022 Discussion/Marine - Fog risk Friday night A ridge of high pressure will be in place Friday night.
1108 AM EDT Thu Oct 27 2022 High pressure and ridging begin to build in today with clouds clearing by the afternoon. Tranquil weather is expected today, with diminishing cloud cover and highs in the 60s Discussion: An upper trough will dig aggressively from the four corners region this morning, into west Texas by tonight. Tonight, clear skies will continue and winds will be light so expect to see temperatures fall into the low 40s.
1005 AM CDT Thu Oct 27 2022 (Issued 1000 AM CDT Thu Oct 27 2022 Ground fog is on the way out and forecast details remain on track as high pressure will provide a dry seasonal day with passing high clouds. High pressure will gradually exit to the east over the next 24 to 36 hours and winds will become southeasterly. Temperatures will be a near carbon copy of yesterday, perhaps a few degrees warmer.
135 PM EDT Thu Oct 27 2022 High pressure will bring a period of dry weather which will last through the weekend. It will be considerably cooler than it has been earlier this week, but there will be a gradual warming trend through this weekend. High pressure across the Northeast will maintain fair weather through Friday. This will result in favorable radiational cooling conditions tonight, with temperatures falling to near or below freezing for most areas, but a touch warmer near the lakes. Patchy valley fog may develop tonight, but expect coverage to be limited due to the dry air mass and below freezing temperatures. Friday will be warmer with highs in the 50s and light winds less than 10 mph.
The ridge will shift eastward through the day today, and low-level flow will become easterly by late this afternoon.
1108 AM MDT Thu Oct 27 2022 At 0830Z, a positively tilted upper trough extends from Manitoba, through the western Dakotas, and into the Central Rockies. At the surface, a weak trof is pushing eastward across the western SD plains.
/NEW/ /Today through Friday/ High clouds streaming east across the region to persist through the afternoon hours, becoming more widespread overnight as an upper-level low pressure approaches the region from the west.
325 PM CDT Thu Oct 27 2022 (Issued 305 PM CDT Thu Oct 27 2022) Tonight through Friday night: High pressure overhead will gradually expand in size heading into tonight, growing to occupy much of the space over the northeastern United States, Great Lakes, and into the eastern Great Plains. The high will be fairly strong as well at roughly 1038mb, and our weather will likely be stable and dry the next few days as a result. Tomorrow will be almost a carbon copy of today with slightly warmer highs in the upper 50s, and more chances for patchy fog at night as temperatures drop into the 30s again.
1 inches) as high pressure remains in control of the low to mid levels, helping to maintain a prominent dry layer between the 500mb and 850mb levels. The dry layer will begin to erode and deeper moisture will begin advecting into the region by Friday evening as high pressure pushes away from the region due to the approach of the upper-level system from the west. Highs will gradually warm from the low to mid 70s on Thursday to the upper 70s to low 80s on Friday. Lows Thursday night will range from the upper 40s for interior counties west of the Tombigbee River, to the low to mid 50s for the remainder of the region.
350 PM EDT Thu Oct 27 2022 The surface analysis reveals high pressure is centered just to the north in Michigan this afternoon. In the upper levels, we see a closed low across the Four Corners region and pretty much flat flow here in the east. Even so will keep the ridge/valley temperature splits going, as the opacity of these clouds should keep it from causing too much of the blanket affect. Given this expect mid to upper 30s for valleys and low to mid 40s for the ridges. Friday night still keep slight ridge/valley temperature splits going and could see these increasing depending on how well we mix out on Friday afternoon.
(Through tonight ) An upper low over New Mexico at this time will continue to dig southeast into west Texas overnight.
1247 PM EDT Thu Oct 27 2022 High pressure and ridging begin to build in today with clouds clearing by the afternoon. Tranquil weather is expected today, with diminishing cloud cover and highs in the 60s Discussion: An upper trough will dig aggressively from the four corners region this morning, into west Texas by tonight. Tonight, clear skies will continue and winds will be light so expect to see temperatures fall into the low 40s.
246 PM CDT Thu Oct 27 2022 High clouds began to overspread the area today as an upper level low dug south into the four corners region. SW flow aloft ahead of the low brought elevated moisture to the area. Closer to the surface, high pressure to the west kept the area dry and lower RH and temps into the 50s today. Temperatures will be slightly warmer tomorrow with quiet weather through the period. Discussion: Closed low south of the area and limited CVA into the area will result in quiet weather for the rest of the period. Ridging above the H5 low will lead to a blocking pattern. With clouds expected to clear overnight, have trended a degree cooler tonight.
1252 PM PDT Thu Oct 27 2022 Quiet, mild and dry conditions prevail through the weekend with generally light valley winds and breezy ridge winds.
1211 PM CDT Thu Oct 27 2022 Seasonably cool and dry conditions will continue for the next few days as high pressure to the northeast continues to be the dominant influence on central Illinois weather.
235 PM CDT Thu Oct 27 2022 A rather quiet stretch of weather is expected through the short term period as high pressure remains dominant across the Great Lakes. High level cloudiness has shifted into the area in advance of an upper low moving over New Mexico this afternoon. Partly to mostly cloudy skies will then continue overhead into tonight, before this higher level cloud cover decreases into early Friday morning. Some patchy fog will again be possible late tonight, especially in any areas that see the higher level cloudiness clear late tonight. Onshore easterly winds may hold areas along the lakeshore a few degrees cooler, however.
With dry high pressure still the dominant feature, mainly clear skies are expected tonight.
256 PM EDT Thu Oct 27 2022 The surface analysis reveals high pressure is centered just to the north in Michigan this afternoon. In the upper levels, we see a closed low across the Four Corners region and pretty much flat flow here in the east. Even so will keep the ridge/valley temperature splits going, as the opacity of these clouds should keep it from causing too much of the blanket affect. Given this expect mid to upper 30s for valleys and low to mid 40s for the ridges. Friday night still keep slight ridge/valley temperature splits going and could see these increasing depending on how well we mix out on Friday afternoon.
300 PM MDT Thu Oct 27 2022 Overview: A robust upper level low -- centered in north-central NM (per 20Z WV imagery and SPC Mesoanalysis data) -- will dig SSE into west TX late tonight. then meander /nearly stall/ over portions of the lower- central MS River Valley (Sat-Sat night). Through Tonight: Light precipitation over northwest KS (mainly east of Highway 83) -- associated with diffluent flow aloft and/or cyclonic shear vorticity on the northern periphery of a ~100 knot jet streak in Oklahoma -- will wane/dissipate late this afternoon and evening (00-06Z) as the aforementioned upper low progresses SSE from NM into west TX. While additional precipitation /convection/ directly associated with the upper low will rapidly develop this evening.
255 PM EDT Thu Oct 27 2022 High pressure centered over Lower Michigan this afternoon will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
437 PM EDT Thu Oct 27 2022 High pressure will build across the region tonight through the weekend.
1214 PM CDT Thu Oct 27 2022 Quiescent weather remains in place through the end of the work week, largely thanks to high pressure of 1025 mb sprawled over the area this morning. A digging strong upper level low across the Four Corners region and a couple of lead short waves over the Plains will fling some cirrus over the area today. As the aforementioned upper low digs into west Texas by late tonight, the downstream response will be upper ridging building into the area from the southeast under a split jet stream flow regime.
604 PM CDT Thu Oct 27 2022 (This afternoon through Friday Night) Sprawling high pressure covered most of the eastern U. Fair wx will continue tonight through Friday with seasonable lows tonight and warmer highs for tomorrow. The next significant wx system coming our way is a low pressure over the Four Corners. The low will move out to Texas by Friday evening.
An upper ridge will shift east tonight and will be replaced with a southwest flow aloft on Friday. Temperatures will be a few degrees warmer with highs close to normal.
520 PM MDT Thu Oct 27 2022 Overview: A robust upper level low -- centered in north-central NM (per 20Z WV imagery and SPC Mesoanalysis data) -- will dig SSE into west TX late tonight. then meander /nearly stall/ over portions of the lower- central MS River Valley (Sat-Sat night). Through Tonight: Light precipitation over northwest KS (mainly east of Highway 83) -- associated with diffluent flow aloft and/or cyclonic shear vorticity on the northern periphery of a ~100 knot jet streak in Oklahoma -- will wane/dissipate late this afternoon and evening (00-06Z) as the aforementioned upper low progresses SSE from NM into west TX. While additional precipitation /convection/ directly associated with the upper low will rapidly develop this evening.
706 PM EDT Thu Oct 27 2022 High pressure will build northeastward from the Ohio Valley toward New England through the weekend.
632 PM EDT Thu Oct 27 2022 Aviation - Fog risk Friday night A ridge of high pressure will be in place Friday night.
539 PM MDT Thu Oct 27 2022 Upper level low that brought the rain and snow to the region will track southeast across the Southern Rockies tonight and across Texas Friday. Upper level ridging builds over Colorado for Friday. Sunny skies and mild temperatures will prevail under the ridge. Friday night, a deep closed upper low will be moving across Northeastern Texas with an upper level ridge of high pressure over Colorado. Over the weekend, a weak upper trough will move across the area with seasonable temperatures expected. Despite the passage of the trough, no precipitation is expected due to a lack of moisture.
623 PM EDT Thu Oct 27 2022 High pressure will build across the region tonight through the weekend.
834 PM MDT Thu Oct 27 2022 The closed upper low continues to dive into central New Mexico this evening with a drying and subsident airmass taking over across Northern Colorado. Upper level low that brought the rain and snow to the region will track southeast across the Southern Rockies tonight and across Texas Friday. Upper level ridging builds over Colorado for Friday. Sunny skies and mild temperatures will prevail under the ridge. Friday night, a deep closed upper low will be moving across Northeastern Texas with an upper level ridge of high pressure over Colorado. Over the weekend, a weak upper trough will move across the area with seasonable temperatures expected. Despite the passage of the trough, no precipitation is expected due to a lack of moisture.
1030 PM EDT Thu Oct 27 2022 High pressure centered over Lower Michigan this afternoon will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
703 PM EDT Thu Oct 27 2022 High pressure centered over Lower Michigan this afternoon will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
1009 PM EDT Thu Oct 27 2022 High pressure will bring a period of dry weather which will last through the weekend. It will be considerably cooler than it has been earlier this week, but there will be a gradual warming trend through this weekend. High pressure sliding across the Ottawa Valley tonight and into northern New England on Friday will maintain fair weather across the region. This will result in favorable radiational cooling conditions tonight, with temperatures falling to near or below freezing for most areas. It will remain locally warmer near the immediate lakeshores though. Patchy valley fog may develop overnight (no sign of it just yet), but expect coverage to be limited due to the dry air mass and below freezing temperatures. Friday will be warmer with highs in the 50s and light winds less than 10 mph.
(Rest of tonight) Tranquil weather across the Tennessee Valley this evening, with high pressure at the surface making for mostly clear and calm conditions. The one caveat will be the high cirrus clouds currently streaming into the area from convection well to the southeast across the ArkLaTex.
High pressure off to our northeast will keep our region dry through Friday night with a gradual increase in high clouds.
740 PM EDT Thu Oct 27 2022 Upper air pattern consists of a 500 mb trough in the central Rockies and a trough across western Quebec.
701 PM EDT Thu Oct 27 2022 High pressure anchored just northeast of the area maintains influence this taf period.
918 PM EDT Thu Oct 27 2022 Temperatures will be near normal as modest to strong high pressure fills in over the region through the remainder of the week. Leaned more toward the SREF means which are of course warmer. High pressure will continue to build down from the north through Friday as the center shifts east from the Great Lakes across to the New England coast by late Fri. Weak isentropic lift and onshore flow in the low levels will produce an increase in moisture tonight into Fri. High pressure will ridge into the area from the north during this period, resulting in mainly fair weather.
729 PM EDT Thu Oct 27 2022 Temperatures will be near normal as modest to strong high pressure fills in over the region through the remainder of the week. The challenge is the lower clouds but the trend of lowering coverage followed by an increase late seems well supported in guidance and is integrated into the forecast. High pressure will continue to build down from the north through Friday as the center shifts east from the Great Lakes across to the New England coast by late Fri. Weak isentropic lift and onshore flow in the low levels will produce an increase in moisture tonight into Fri. High pressure will ridge into the area from the north during this period, resulting in mainly fair weather.
652 PM CDT Thu Oct 27 2022 (Through tonight ) An upper low over New Mexico at this time will continue to dig southeast into west Texas overnight.
742 PM EDT Thu Oct 27 2022 Drier and slightly cooler airmass tonight will give way to more cloudiness across the area by Friday and through the weekend. Surface front well offshore with weak area of low pressure along its boundary.
731 PM EDT Thu Oct 27 2022 High pressure centered over Lower Michigan this afternoon will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
