1230 PM CDT Fri Oct 21 2022 Cold front is now through the region with clear sky in post frontal subsidence. Before this upper wave brings clouds and the light rain chances, the region will be under the influence of weak low level ridging, leading to clear sky and low level westerly flow. Airmass will be cooler compared to yesterday, but mixing of dry air aloft to the surface brings the potential for afternoon humidity values 25%-35%.
(through Tonight) The region will be between a ridge of high pressure to the west northwest, and an inverted trough to the southeast through Tonight. Most of the moisture associated with this trough will remain to the southeast Tonight, so dry forecast remains in place, but a few clouds will move into NE FL coastal counties. Temperatures will be milder Tonight, especially along the NE FL coast due to the flow over the relatively warmer waters.
Beautiful days with mostly clear skies across our region as we are under the influence of a strong high pressure ridge. Highs for tomorrow are forecast to be in the lower 80s, with overnight lows in the mid 50s north to the lower 60s south. Mostly clear skies and rain free over the coastal waters as an area of high pressure continues to stretch over the waters. Cooler/drier air remains in place for today, temperatures should start to warm a little bit during the weekend.
An upper trough will begin digging southward over the western part of the country on Saturday. Highs on Saturday may reach the lower 90s across parts of the Permian Basin, along and near the Pecos River, and along the Rio Grande. In fact, the high temperature at Midland may be near the record high of 91 for Saturday.
137 PM EDT Fri Oct 21 2022 Only updates this morning were blending observations to the immediate forecast and nudging the highs today with newest model data. Short term forecast through Saturday night is otherwise still on track with quiet and high pressure driven weather conditions prevailing. Warmer temperatures today.
Although dew points have risen into the 30s, temperatures are also notably warmer than yesterday, which is still keeping relative humidities pretty low. As far as the typical sensible weather goes, we'll see temps peaking in the low to mid 70s this afternoon under mostly sunny skies. Saturday brings some more variable high clouds with even warmer temperatures pushing toward the 75 to 80 degree range as low level thicknesses continue to rise. The continued moist advection in the low levels will make afternoon RH less of a concern through the weekend, but still could see some marginal burning conditions at times, especially as small and medium fuel continue to dry out with worsening drought conditions.
A deepening marine layer through today will precede a fairly quick moving cold front arriving from the northwest tonight and early Saturday morning.
133 PM EDT Fri Oct 21 2022 A calm and quiescent weekend is on tap as high pressure nudges north from the Mid-Atlantic states to the Atlantic coastline of the Northeast. Highs this afternoon will reach the lower or even mid 60s across the lake plains, upper 50s elsewhere. Temps aloft keep warming into Saturday and with decent mixing many areas will reach the lower 70s with at least mid 60s for the higher terrain. It will stay quiet with just some high clouds increasing as low pressure system begins to edge up east coast late.
an expanding thermal ridge over the region combined with the gusty winds will help afternoon temps climb into the low/mid 80s for Northwest Arkansas and mid/upper 80s for much of Eastern Oklahoma. with the lowest values along and west of Highway 75 in Northeast Oklahoma.
Tonight won't be nearly as chilly as the past several nights when many locations dropped to freezing or below. (It will be quite some time before we experience freezing temperatures again. ) Tomorrow we'll remain sunny and even warmer than today.
343 PM EDT Fri Oct 21 2022 Discussion/Marine -- Sunny, Warm and Breezy Weekend -- Continued warm advection over the next few days ahead of an evolving cyclone in the lee of the Rockies will send high temperatures into the 70s.
At the surface, high pressure is continuing to build over the Appalachians and Mid-Atlantic region, providing calm and dry conditions. A ridge aloft with it's axis extending SW to NE will build in higher heights, thus warming temperatures each day. Valley locations will break into the low 70s for Saturday afternoon. Very localized dense fog around bodies of water is possible in the early morning hours under high pressure and little to no wind.
/CRJ/ Today and Tonight: Continued dry through the period and a return to warmer than normal temperatures is expected. Early morning water vapor imagery/RAP analysis showed the axis of the upper level trough that has been over the region the last several days, has shifted east of Mississippi. Thus, ridging surface and aloft today and tonight will lead to warmer than normal temperatures. Highs will top out from the upper 70s east to the lower 80s west. Lows Saturday will range from the lower 50s east to the upper 50s west.
351 PM EDT Fri Oct 21 2022 High pressure will build southeast of the region through tomorrow.
309 PM EDT Fri Oct 21 2022 High pressure will remain nearby through Saturday.
Temperatures early this morning are running warmer than the past several mornings, currently mainly in the upper 30s to mid 40s over most of the interior, but upper 40s to mid 50s closer to and along the coast. Models have been consistent in showing that the deep upper trough axis over the eastern CONUS will gradually shift east and weaken through late this week, with a weak remnant upper low lingering over the Atlantic just off the southeast coast(to the east of Georgia and Florida by the end of the day Saturday). As this occurs, upper riding on the backside of the trough will build over our area.
1209 PM CDT Fri Oct 21 2022 Today: A cold front presently residing over northern SD very early this morning will continue to drop southward through the morning hours, exiting our CWA around 15Z. With ensuing warm air advection and increasing winds, temperatures will remain above seasonal normals, dropping into the lower to mid 40s.
313 PM CDT Fri Oct 21 2022 Current model guidance show a ridge axis lifting out of our CWA by tonight. As the ridge axis lifts out of our area, winds will be steady most of the night due to a pressure gradient holding. This will result in overnight lows roughly 10 degrees warmer than previous nights with lows generally 50-60 degrees.
205 PM MDT Fri Oct 21 2022 Potent upper trough beginning to dig into the western CONUS as semi-active easterly flow continues over the Northern Plains. This will support breezy SW winds south of the warm front into NE WY and southern SD, along with mild and dry weather Sat. Long wave upper trough will slide east Sat night with the sfc cold front entering the western FA.
Cronce (Issued 218 AM CDT Fri Oct 21 2022) Today and Tonight: Transition to a warmer southwesterly flow at the surface and aloft from this afternoon into tonight over the forecast area. This is the beginning of a much warmer forecast for southern Wisconsin.
1110 AM EDT Fri Oct 21 2022 Only updates this morning were blending observations to the immediate forecast and nudging the highs today with newest model data. Short term forecast through Saturday night is otherwise still on track with quiet and high pressure driven weather conditions prevailing. Warmer temperatures today.
606 PM EDT Fri Oct 21 2022 The weekend will remain warm and dry under a ridge of east coast high pressure. This forecast period will be dominated by dry conditions and mostly clear skies under high pressure and affiliated broad subsidence. The high pressure ridge axis sits along the eastern seaboard, while the Great Plains and upper Great Lakes region sits in a low pressure trough. The northeast to southwest oriented pressure gradient will allow warm air to continue to move in from the south, leaving our area warmer than days prior. Lows for tonight should likely remain near average and above freezing for the entire region.
304 PM PDT Fri Oct 21 2022 After another day of dry and unseasonably warm conditions, a low pressure system will move through the Great Basin on Saturday and bring much cooler weather through the weekend along with increased winds.
This has caused a collision of air masses to occur, which has helped produce an upper level trough over the northern United States. Tonight: Upper level flow will become more southwesterly as the trough strengthens, which will maintain cloud cover and increase precipitation chances over the region.
608 PM EDT Fri Oct 21 2022 The weekend will remain warm and dry under a ridge of east coast high pressure. This forecast period will be dominated by dry conditions and mostly clear skies under high pressure and affiliated broad subsidence. The high pressure ridge axis sits along the eastern seaboard, while the Great Plains and upper Great Lakes region sits in a low pressure trough. The northeast to southwest oriented pressure gradient will allow warm air to continue to move in from the south, leaving our area warmer than days prior. Lows for tonight should likely remain near average and above freezing for the entire region.
Strong low-level jet is situated over the Plains, with more low-level 850mb ridge right over the FL Panhandle. With broad sfc cyclone developing into the Plains, increased pressure gradient near 4-5mb will persist into the overnight hours. With increased gradient winds, lows will be above climo & only fall into the mid-upper 50s for areas along & W of I-55, while decreased gradient winds in the I-59 to Hwy 45 corridor will support better rad cooling into the low 50s. /DC/ Current model guidance show a ridge axis lifting out of our CWA by tonight. As the ridge axis lifts out of our area, winds will be steady most of the night due to a pressure gradient holding. This will result in overnight lows roughly 10 degrees warmer than previous nights with lows generally 50-60 degrees.
659 PM CDT Fri Oct 21 2022 Current model guidance show a ridge axis lifting out of our CWA by tonight. As the ridge axis lifts out of our area, winds will be steady most of the night due to a pressure gradient holding. This will result in overnight lows roughly 10 degrees warmer than previous nights with lows generally 50-60 degrees.
High pressure ridging NE/SW down the E Seaboard into the E Gulf maintains dry conditions and light N'ly winds this evening with mostly clear skies over WCFL and a few stray clouds over parts of SWFL. Beautiful days with mostly clear skies across our region as we are under the influence of a strong high pressure ridge. Highs for tomorrow are forecast to be in the lower 80s, with overnight lows in the mid 50s north to the lower 60s south. Mostly clear skies and rain free over the coastal waters as an area of high pressure continues to stretch over the waters. Cooler/drier air remains in place for today, temperatures should start to warm a little bit during the weekend.
Given the crossover temperatures still below 32F, expect good radiative cooling to near freezing overnight. Look for a seasonably cool night with minimum temperatures in the lower 30s in the coldest sheltered northeast hollows up to the upper 40s over thermal belt ridges. Present surface analysis has an elongated surface 1023mb high pressure center situated along the eastern seaboard. However, aloft a moisture starved trough is working its way through the flow. Only indication of the trough is the increased surface winds and the cirrus clouds crossing through the region. The trough will eject to the east overnight and upper-level zonal flow will take over at the main regime. At the lower levels, southwesterly flow will dominate through the day Saturday. The southwesterly flow will advect warmer and drier air into the region.
(This afternoon through Saturday) High pressure over the area will continue to dominate the weather pattern and keep things dry through the weekend.
509 PM MDT Fri Oct 21 2022 Potent upper trough beginning to dig into the western CONUS as semi-active easterly flow continues over the Northern Plains. This will support breezy SW winds south of the warm front into NE WY and southern SD, along with mild and dry weather Sat. Long wave upper trough will slide east Sat night with the sfc cold front entering the western FA.
609 PM EDT Fri Oct 21 2022 High pressure will build southeast of the region through tomorrow.
A cold front will bring some light rain to mainly the northern portions of the area tonight.
222 PM PDT Fri Oct 21 2022 A deep trough of low pressure moving southeast across the Great Basin this weekend, bringing much cooler weather along with strong and gusty winds in the mountains and deserts.
735 PM EDT Fri Oct 21 2022 Aviation -- Sunny, Warm and Breezy Weekend -- Continued warm advection over the next few days ahead of an evolving cyclone in the lee of the Rockies will send high temperatures into the 70s.
Coolest readings will be out in our eastern valleys where lows in the upper 30s to the lower 40s are expected. Although dew points have risen into the 30s, temperatures are also notably warmer than yesterday, which is still keeping relative humidities pretty low. As far as the typical sensible weather goes, we'll see temps peaking in the low to mid 70s this afternoon under mostly sunny skies. Saturday brings some more variable high clouds with even warmer temperatures pushing toward the 75 to 80 degree range as low level thicknesses continue to rise. The continued moist advection in the low levels will make afternoon RH less of a concern through the weekend, but still could see some marginal burning conditions at times, especially as small and medium fuel continue to dry out with worsening drought conditions.
916 PM EDT Fri Oct 21 2022 High pressure will remain nearby through Saturday.
Otherwise, still expecting warmer minimum temperatures generally in the 30's to lower 40's. At the surface, high pressure is continuing to build over the Appalachians and Mid-Atlantic region, providing calm and dry conditions. A ridge aloft with it's axis extending SW to NE will build in higher heights, thus warming temperatures each day. Valley locations will break into the low 70s for Saturday afternoon. Very localized dense fog around bodies of water is possible in the early morning hours under high pressure and little to no wind.
637 PM CDT Fri Oct 21 2022 (This evening through Saturday) Above normal temperatures will continue across West Central Texas through the next 24 hours, as weak upper level ridging dominates the region.
Weak WAA/isentropic ascent continues to support mid-high level cloudiness ahead of the trough mainly over eastern counties of the U. Tonight, with models indicating weak ridging moving across the area along with clearing skies and light winds, expect min temps to dip into the lower to mid 30s inland to upper 30s/low 40s closer to the Great Lakes. Downstream ridging will allow upper heights to rise significantly across the east half of the U.
Meanwhile, at the surface a 1021 mb ridge of high pressure is centered over the East Coast with southerly flow bringing mild temperatures and slightly higher dewpoints up into the Mid-South this evening.
Temperatures will continue to drop off, but end up being much warmer than we've seen over the last several nights thanks to a southwesterly flow that developed over the last 24 hours.
Pleasant conditions have finally returned to SE MI today as this week's persistent upper level trough has slid east into northern Quebec with low amplitude ridging quickly following in its place. Ample sun and ongoing WAA under this ridge has aided temperature recovery from the cold morning start with the bulk of the region now sitting in the mid to upper 60s. Upper level ridging over the Great Lakes undergoes amplification this weekend as a potent upper trough digs into the Pacific Northwest and eventually the rest of the western CONUS. Resultant highs will be much above normal as temperatures top out in the low to mid 70s both days. Lows likely stay in the lower 50s each night due to the combination of persistent southerly winds along with slightly more accompanying moisture in this airmass as dewpoints hold around 50.
Highs across the board will be in the low to mid 80s.
632 PM EDT Fri Oct 21 2022 The weekend will remain warm and dry under a ridge of east coast high pressure. This forecast period will be dominated by dry conditions and mostly clear skies under high pressure and affiliated broad subsidence. The high pressure ridge axis sits along the eastern seaboard, while the Great Plains and upper Great Lakes region sits in a low pressure trough. The northeast to southwest oriented pressure gradient will allow warm air to continue to move in from the south, leaving our area warmer than days prior. Lows for tonight should likely remain near average and above freezing for the entire region.
Compact mid level cut off low just offshore ECFL will pivot NE Sat, then turn north and open up into a trough as it reaches NC on Sun. Sat temps U70s-L80s/L60s with Sun about 2F warmer for both maxes and mins.
Rain and mountain snow is expanding throughout the region as a trough begins to overtake the Northern Rockies. Overall the forecast remains on track with much cooler temperatures and lowering snow levels through the weekend.
(Tonight) Clear skies continue on the western edge of an area of high pressure that extends from the Mid-Atlantic area into the Florida panhandle. In sheltered areas of northeastern Alabama, where winds will remain lighter until closer to midnight or shortly after, lows should be able to drop into the lower to mid 40s.
1236 AM CDT Sat Oct 22 2022 (Tonight) Clear skies continue on the western edge of an area of high pressure that extends from the Mid-Atlantic area into the Florida panhandle. In sheltered areas of northeastern Alabama, where winds will remain lighter until closer to midnight or shortly after, lows should be able to drop into the lower to mid 40s.
(Saturday night through Sunday night) Ridging throughout the short term will allow fair weather to prevail; light winds, mostly clear skies and dry conditions.
A low level ridge along the Atlantic Coast will produce south to southeast winds 5-8 mph today and again Sunday.
123 AM PDT Sat Oct 22 2022 A trough of low pressure entering the Great Basin will lead to significantly cooler temperatures today, along with gusty winds in wind-prone areas of Central California. A major change in the weather pattern is in store for Central California as a stout inside-slider trough enters the Great Basin. Gusty conditions through Tioga Pass are also likely to occur this morning through this evening as the upper jet associated with this trough moves overhead.
Southwesterly flow aloft will continue for most of the period as the trough digging the western CONUS cuts off over the Rockies tonight into Sunday. A surface warm front will lift into our southern counties later today as low pressure develops to our southwest. There should be quite a spread in temperatures today, ranging from the low 50s near the Canadian border to low 70s in west central MN. The warm front will continue to lift north tonight, although less cloud cover could drop surface temps a bit lower than this morning, down into the upper 30s and 40s.
418 AM EDT Sat Oct 22 2022 (Today through Sunday) As the last lingering piece of upper trough energy cuts off to the east and phases with some Atlantic moisture, the low should stay off the coast tracking north near the mid-Atlantic region by Sunday and allow for a continued dry ridge dominated regime for the CWA through this weekend. Temps look to continue to moderate warmer and highs today should make it to about a degree or so below climo with many locations in the low 70s. Lows tonight will still have some decent radiational cooling but will be warmer than past days and should stay in the 40s without any frost/freeze concerns.
(Now through Sunday) The pressure gradient along the lower Texas coast tightens this weekend as a ridge of high pressure along the East Coast builds and low pressure across the Rockies and Plains deepens. Hurricane Roslyn is expected to make landfall along the west-central coast of Mexico late tonight or early Sunday, quickly losing steam as it runs into the higher terrain of Northern Mexico.
254 AM EDT Sat Oct 22 2022 The weekend will remain warm and dry under a ridge of east coast high pressure. GOES nighttime microphysics shows a nearly entirely clear sky across the forecast thanks to high pressure in place. A beautiful day for the area is on deck as plenty of sunshine coupled with warm air advection will result in considerably warmer conditions. With another night of optimal radiational cooling expected, look for temps to quickly drop, eventually reaching the lower 40s and upper 30s before daybreak Sunday.
Winds will be more from the south than southwest though, which will result in a chance for somewhat cooler temps in lakeshore areas. Temps will remain mild tonight with the low level jet sitting overhead, with lows 15-20 degrees above average values for the second half of October.
(Today through Sunday) South Florida remains located between an area of high pressure centered over the Gulf and a trough over the Atlantic waters. The low being to the northeast of the area will allow drier air to be reinforced over the region as it wraps into the low aloft. On Sunday, the low will begin a northward progression towards the Carolinas and mid-Atlantic coast.
An upper level low is in the initial stages of becoming a cut-off low just east of the Space Coast of Florida this morning. This new upper level low will gradually lift northeast along the Eastern Seaboard coastline and away from the Sunshine State. Interesting enough, although the low itself will trek northeast, the parent trough will remain trapped off the southeast U. At the same time, upper level ridging will build in from the west.
Details: Today expect the upper pattern to gradually shift from near zonal as a trough deepens over the western US. This will allow for continued southerly winds drawing in even warmer temperatures. Temperatures this afternoon will be well above normal with most topping out in the low 80s.
A weakening cold front is folding over across eastern upper/far northern lower MI. The front should still be discernible this afternoon, slowly moving north across far northern lower MI as a warm front. Max temps today in the lower 60s in eastern upper MI, upper 60s to mid 70s in northern lower MI (expect TVC to be the warm spot again).
Weak WAA/isentropic ascent continues to support mid-high level cloudiness ahead of the trough mainly over eastern counties of the U. Tonight, with models indicating weak ridging moving across the area along with clearing skies and light winds, expect min temps to dip into the lower to mid 30s inland to upper 30s/low 40s closer to the Great Lakes.
Baker (This afternoon through Saturday) High pressure over the area will continue to dominate the weather pattern and keep things dry through the weekend.
What we do have are abnormally warm and climbing temperatures that have made it to the upper 70s area-wide, and will see a bump up to the low-to- mid 80s Saturday afternoon. Along with the dry airmass, winds out of the south will gust to 15-25 mph and make for very high fire danger where the lowest RHs occur (mainly in northwest into central Nebraska).
1243 AM CDT Sat Oct 22 2022 (This evening through Saturday) Above normal temperatures will continue across West Central Texas through the next 24 hours, as weak upper level ridging dominates the region.
(Today and tonight) Above normal temperatures are expected again today across West Central Texas, as weak upper level ridging dominates the region.
(Today through Sunday) Slight ridge building across the region while moving east.
