As far as temperatures today expect to see a few degrees warmer than yesterday with most reaching the low 70s. Temperatures will be just a bit cooler with mid to upper 60s expected across the area.
723 AM EDT Wed Oct 18 2023 High pressure returns for the next few days, but it will still remain mostly cloudy for most today with improving conditions for Thursday.
Cooler weather and a chance for precipitation will return for the weekend. As the upper ridge continues to nose into the Pacific Northwest the warm-up will continue, especially for today and tomorrow.
339 AM MDT Wed Oct 18 2023 - Cooler temperatures expected today, yet still above normal.
859 AM EDT Wed Oct 18 2023 Moderating temperatures expected into Thursday as high pressure moves over and east of the region.
534 AM MDT Wed Oct 18 2023 - Cooler temperatures expected today, yet still above normal.
1027 AM EDT Wed Oct 18 2023 A ridge of high pressure at the surface and aloft will be drifting east across the commonwealth today and bring with it, gradually improving weather conditions are expected through Thursday.
825 AM EDT Wed Oct 18 2023 Dry high pressure will ensure fair and slightly cool conditions today, with some slight moderation in temperatures Thursday.
A weak cold front currently in southern Kansas will move south later this morning reaching first southeastern New Mexico around noonish, before reaching the I-20 corridor by sunset and continuing south overnight. The frontal passage will be denoted mainly by a northerly or northeasterly wind shift, temperatures will be slightly cooler behind the front but remain above normal for this time of year. Highs today will be in the upper 80s to low 90s and tomorrow will only drop into the low to mid 80s.
Today and tonight the region will be between high pressure over the East Coast and low pressure crossing the upper Midwest with a cold front reaching down to Texas. This will put us in a regime of SSW breezes and warmer temperatures under partly cloudy skies. With thickening mid/upper clouds tonight and continued WAA, temperatures will only drop into the low and mid 50s for most.
741 AM EDT Wed Oct 18 2023 High pressure over the eastern U. will drift east out into the Atlantic Ocean Thursday, but continue to ridge southwestward across the region with the fair dry weather persisting.
734 AM EDT Wed Oct 18 2023 Dry high pressure will ensure fair and slightly cool conditions today, with some slight moderation in temperatures Thursday.
Otherwise, north-northwest flow aloft will dominate as a ridge of high pressure remains over the western CONUS throughout the short term periods. Given the warm temperatures and resultant humidities near or just under 15%, some localized and brief near-critical fire weather will be possible across the lowest elevations in this area. Dry and warmer conditions will continue through the weekend as a ridge of high pressure amplifies across the west.
750 AM EDT Wed Oct 18 2023 Aviation - Dry Today, Showers Tonight into Thursday A distinct upper low is evident on mid level WV imagery over the Dakotas, and this feature is slated to arrive by Thursday. The upper low will arrive by peak heating, so it is conceivable that a few lightning strikes could be generated from this system given this is already occurring across the Dakotas and we will have at least some weak support for lightning activity and perhaps hail generation as well.
628 AM CDT Wed Oct 18 2023 (Wednesday through Thursday) It looks like our region is in store for another mostly quiet short-term, as upper-level ridging slowly builds in to our west. Highs today and tomorrow will begin to slightly climb because of the ridge, with afternoon highs getting into the low-80s by Thursday. There is a very small chance for rain in our north zones overnight tonight, as a trough and cold front move through the midwest.
321 AM MST Wed Oct 18 2023 Continued high pressure will help keep temperatures well-above normal through the remainder of this week.
Key Messages: - Short period of strong winds with gusts up to 60 mph this morning as system exits region - Above average temperatures and breezy conditions to end the work week Surface analysis depicts low pressure centered over northeastern North Dakota with midlevel water vapor imagery depicting the upper low centered over western North Dakota. Relatively cooler air will filter into the region today with near average highs in the 60s. Upper ridge builds over the western US and puts us under northwesterly flow. Warmer air with above average temperatures will return once more to end the week.
630 AM CDT Wed Oct 18 2023 Dry weather and warmer temperatures are expected today with highs in the low to mid 70s. Scattered showers will move across mainly northern and western section of the Mid-South tonight as a cold front moves into northwest Arkansas. The cold front will cross the Mississippi River by late Thursday afternoon with more showers moving across the region.
625 AM EDT Wed Oct 18 2023 High pressure will bring dry weather today and Thursday, along with seasonable temperatures.
We can expect another cool morning, with temperatures dipping into the low 50s just west of Lake O, mid to upper 50s in the Gulf coast metro areas, and low 60s along South Floridas eastern coast. As a result, temperatures will slowly climb, as high temperatures this afternoon should reach the lower 80s. As a result, gradual warming and influx of moisture will continue, with afternoon maximum temperatures climbing into the low/mid 80s, and dew points climbing up into the low/mid 60s. Otherwise an overall dry and mild day, albeit warmer than what has been experienced recently.
959 AM CDT Wed Oct 18 2023 The center of the low pressure system is located in NE SD this morning and continues to push eastward. Rain showers to the east of the upper low over the RRV and moving north, while a band of rain is on the west/northwest side moving south in central ND from Minot to near Bismarck. Cooler today due to more clouds and a north wind but still highs in the 50s, mostly mid-upr 50s, which is still a bit above normal.
526 AM CDT Wed Oct 18 2023 (Today through Thursday) Mostly clear skies and rain-free conditions are expected today as high pressure shifts to our east and weak ridging aloft slides through the region. High temperatures will be in the 70s for much of the area with a few of our cooler locations in the east and northeast remaining in the upper 60s due to cooler air filtering into the valleys. An upper level trough will slide into the Deep South later tonight leading to increasing clouds after midnight. A cold front is expected to move in later Thursday and will lead to increasing rain chances in the western and northwestern counties Thursday afternoon into the early evening hours.
844 AM EDT Wed Oct 18 2023 High pressure returns for the next few days, but it will still remain mostly cloudy for most today with improving conditions for Thursday.
459 AM MDT Wed Oct 18 2023 Key Messages: - Short period of strong winds with gusts up to 60 mph this morning as system exits region - Above average temperatures and breezy conditions to end the work week Surface analysis depicts low pressure centered over northeastern North Dakota with midlevel water vapor imagery depicting the upper low centered over western North Dakota. Relatively cooler air will filter into the region today with near average highs in the 60s. Upper ridge builds over the western US and puts us under northwesterly flow. Warmer air with above average temperatures will return once more to end the week.
and Thursday Middle and high clouds were increasing at 300 am ahead of an upper low that will move from the Dakotas this morning to northern Illinois by Thursday afternoon.
High pressure will promote dry conditions Thursday.
Conditions will be slightly warmer across the Panhandle, especially coastal communities, as light southerly flow in advance of our next system begins to materialize.
(Now through Thursday) Upper level zonal flow will become southwesterly tonight into Thursday as an upper trough digs southward across the midwestern states. This trough will send a cold front into the southeastern states by late Thursday. Southerly sfc flow ahead of the approaching trough and cold front will bring increasing clouds and low level moisture into the area through the day on Thursday. This will allow for warmer temps and the possibility of an isolated shower near the coast and offshore. Lows tonight will be warmer due to increasing moisture and clouds with upper 40s and low 50s inland to low 60s along the coast.
108 PM EDT Wed Oct 18 2023 High pressure will build over the Mid-Atlantic region today. As the high moves away on Thursday, low pressure begins to organize to the west.
1219 PM CDT Wed Oct 18 2023 (Today through Thursday) A potent low pressure system works into the Great Lakes and deepens the mid level trough across the eastern CONUS into late this week. This strengthens the mid-level ridge of high pressure in control across Texas and brings additional dry air into Thursday. Expect a slightly less cooler, but still comfortable night, with highs on Thursday across the CWA topping 90 degrees in most locations.
---BMickelson Previous discussion: High pressure will build into eastern Montana today with diminishing winds. Upper ridge will build into Montana from the west today. The ridge will remain over the area into the weekend with warm and dry weather.
221 PM EDT Wed Oct 18 2023 High pressure will persist through Thursday.
158 PM EDT Wed Oct 18 2023 (Today and tonight) Weak ridging builds into the area today briefly before a longwave trough approaches the Mississippi River by daybreak Thursday. At the surface, high pressure will slide off to our east over the Mid- Atlantic. Thus, the low temperatures range from the upper 40s across much of the area with low to mid-50s in the Panhandle.
343 PM EDT Wed Oct 18 2023 Low pressure will approach from the west overnight and track across the Upper Great Lakes Thursday, bringing a chance for rain.
320 PM EDT Wed Oct 18 2023 High pressure will move offshore Thursday with winds shifting southerly.
Southerly flow has provided a WAA regime, wih temps warming to the upper 60s and near 70 across our southwest, though cooler temps to our east where WAA is a bit weaker. Very thin upper clouds are streaming across the region, with some isolated cu developing where sfc temps are a bit warmer. While we are mostly clear and quiet here, an upper low is evident on GOES satellite imagery located over southwestern Minnesota. The upper level trough will sharpen and dig deeper overnight and into tomorrow. Along with the increasing cloud cover, we will have mild temps overnight, with lows in the low to mid 50s for most. Ahead of the approaching cold front, WAA will remain in place as the sfc pressure gradient tightens and southerly winds become gusty.
We are on track to reach the lower 70s for most of Middle Tennessee, with mid to upper 60s for the Plateau. Upper level ridging and southerly low level flow will allow temperatures to climb nicely today into the mid 60s to lower 70s.
(This evening through Thursday) High pressure remains in control across a good portion of the eastern CONUS today, with tranquil weather conditions present across the Southeast. Temperatures are still on track to top out in the low to mid 70s this afternoon. I wouldn't rule out a few low to mid 40s in the normally cooler spots with good radiational cooling. High cirrus clouds will be on the increase early Thursday morning as a longwave trough approaches from the Great Plains states. A surface cold front is expected to approach northwest Alabama by late Thursday afternoon with increasing rain chances. PoPs will remain confined to western and northwest counties through 7pm Thursday with similar afternoon highs in the low to mid 70s.
Upper level ridging continues to build in from south to north across the state today bringing dry conditions for the rest of tonight through tomorrow. Forecasted high temperatures for tomorrow are in the high 60s to high 70s, being 10 to 20 degrees well above normal as our normal temperature this time of year is the 50s.
With a strong dome of high pressure layered across the mid/southern Atlantic states, a quiet/tranquil wx pattern will continue into the late afternoon period, as near seasonal highs climb well into the lower 70s/near 70F, under mostly sunny skies.
Daytime highs will peak the mid-upper 80s with several locations reaching the lower 90s; in other words 10-15 deg above normal for mid October. These unseasonably warm temperatures will persist into the weekend due to both surface and upper ridging in place.
(This evening through Thursday) Northwesterly surface winds behind a weak cold front will keep overnight lows in the upper 40s to low 50s across the area.
(Through tonight ) Today's cold front will progress through the forecast area overnight tonight, fully exiting to the southeast by tomorrow morning. Low temps may be a touch cooler tonight with some minor cold air advection occurring behind the front, but overall expect 40s and lower 50s. (Tomorrow through Wednesday) Post-frontal NW flow will quickly fill in behind the front tomorrow as the region becomes sandwiched between an amplified eastern CONUS trough and western ridge.
1241 PM CDT Wed Oct 18 2023 (Today through Thursday) Southerly flow will continue through the short term period, bringing warmer air into the area. High temperatures in the low to mid 80s today will increase Thursday into the mid to upper 80s.
Key Messages: - Blustery and cooler today with scattered showers An upper low/trof quite evident over ND this morning will continue to truck southeast today over the forecast area. Meanwhile, a sfc cold front will push east into MN this morning. For later this morning and afternoon convectively driven showers are expected to develop and rotate around the upper low as it moves through the region, ending in the evening. Temperatures will be cooler today in the post frontal airmass that is infiltrating the CWA. We will find ourselves in between an upper ridge anchored across the western CONUS and an upper trough across the Great Lakes, New England and eastern seaboard. At the onset of this period, we'll be watching a warm front sweep west to east across the Dakotas in association with a clipper like system.
123 PM EDT Wed Oct 18 2023 High pressure returns for the next few days, but it will still remain mostly cloudy for most today with improving conditions for Thursday.
Winds will diminish tonight although remain high enough to moderate lows well above freezing, even over the notoriously cold Muleshoe area. Mostly sunny skies and highs in the low-to-mid 80s are expected.
336 PM EDT Wed Oct 18 2023 High pressure will linger through Thursday.
High temperatures will warm into the lower to middle 70s thanks to the low-level WAA. Low temperatures will be warmer thanks to BKN to OVC skies, with values only falling into the lower to middle 50s. High temperatures will again reach the lower to middle 70s.
Lots more sunshine on tap for today with winds from the SW also adding to a little warmer feel to our Wednesday afternoon.
Tonight and Thursday A slow moving mid to upper level low will be the main focus for the short term forecast. Warm air advection ahead of the low gradually brought in mid to upper level cloud cover for the region this morning and afternoon. The dry period will bring a chance for some patchy fog, especially in the cooler spots across central and far northern Wisconsin. Thursday, the upper trough and mid level low will still be working its way across the region. Increased pops to account for the better shower potential, but suspect that rainfall amounts will still be on the lower end. Temperatures will likely be a few degrees cooler than today, as the day will start off more cloudy.
1005 AM CDT Wed Oct 18 2023 The warming trend will continue through this afternoon as a ridge remains over the MidSouth. Highs are expected to range in the low to mid 70s. Furthermore, a cold front is currently in the upper Mississippi Valley and extending southwest into the Central Plains. As the cold front continues to push east, a few light showers will enter the MidSouth this evening. Dry weather and warmer temperatures are expected today with highs in the low to mid 70s. Scattered showers will move across mainly northern and western section of the Mid-South tonight as a cold front moves into northwest Arkansas. The cold front will cross the Mississippi River by late Thursday afternoon with more showers moving across the region.
231 PM EDT Wed Oct 18 2023 High pressure with fair and slightly cool conditions today, with some slight moderation in temperatures Thursday.
As alluded to in the previous discussion, expect isolated to scattered showers to prevail this afternoon and evening as a pronounced upper level low near Iowa and it's associated sfc cold front edge closer to the region. Lows during this time will also remain fairly mild under cloudy skies, with temperatures only falling into the lower 50s. Upper level trough deepens across the Great Lakes region Thursday, with the aforementioned cold front still progged to advance eastward across our area. Highs during this time will be a touch cooler than today, with values ranging from the mid to upper 60s.
(The rest of today ) Upper low digging across the midwest this morning is bringing some limited thunder with high-based convection across northern Kansas. Forcing from the approaching trough axis will spread across the region late this afternoon and evening with a notable increase in cloud cover across northeast Oklahoma into northwest Arkansas.
255 PM CDT Wed Oct 18 2023 (Issued 255 PM CDT Wed Oct 18 2023) Tonight through Thursday night: The high based and very light showers over srn WI will increase in coverage and intensity from nw IL into se WI this afternoon and evening. At the sfc, low pressure will slowly move across nrn Lake MI on Thu with the trailing cold front across srn WI.
107 PM EDT Wed Oct 18 2023 A ridge of high pressure at the surface and aloft will be drifting east across the commonwealth today and bring with it, gradually improving weather conditions are expected through Thursday.
(Tonight through Thursday night) High pressure is centered over SE Louisiana with the ridge axis trailing across the western Gulf of Mexico to around Tampico. The return flow has been warming South Texas today with the temperatures in the lower to mid 80s. In North Texas, Low pressure is moving south east into East Texas, with a cold front that stretches into the Big Bend Region.
A few light showers, moving along and ahead of a surface cold front, will enter the region this evening and continue through tomorrow evening.
However, with the ridge to the west inching ever closer, centering near the Four Corners Region, temperatures are expected to rebound into the 80s across the combined OK/TX Panhandles tomorrow afternoon.
Much warmer air aloft will advect in during this period, and this will allow surface temperatures to once again increase over the region. As for tonight's mins, temps will be a few degrees cooler than this AM's lows due to mainly clear and calm conditions (no mixing due to frontal passage as occurred last night).
These changes will be driven by a solid weather system (well established cyclone per vapor imagery over the N Plains) that will continue to drop southward through the MS River Valley on Thursday. This closed low feature will eventually do some phasing and evolve into a long wave trough across the E CONUS. Temperatures will be warmer than the prev days with more 50s tonight. Clouds will slow the warmup initially tomorrow, but more of a mix of sunshine for the afternoon will allow for warmer readings with upper 70s to lower 80s.
(This afternoon through Thursday night) The only exciting system in the short term is an upper level low situated over the northern Plains, sending a backdoor cold front down to our area today. With this wind shift, weak CAA on Thursday looks to help mitigate afternoon warming, and highs for the afternoon should top out in the low to mid 80s, still above normal. As the upper low moves into the Mississippi Valley Thursday night, upper ridging will begin to rebuild across the west and temperatures will warm quickly for the end of the week.
143 PM EDT Wed Oct 18 2023 Moderating temperatures expected into Thursday as high pressure moves over and east of the region.
1151 AM MDT Wed Oct 18 2023 - Cooler temperatures expected today, yet still above normal.
--Lingering clouds, slightly cooler tomorrow, few sprinkles possible east.
1242 PM CDT Wed Oct 18 2023 (The rest of today ) Upper low digging across the midwest this morning is bringing some limited thunder with high-based convection across northern Kansas. Forcing from the approaching trough axis will spread across the region late this afternoon and evening with a notable increase in cloud cover across northeast Oklahoma into northwest Arkansas.
(Tonight) Tranquil weather will continue this evening across the Tennessee Valley as high pressure gradually shifts east of the area. Cloud cover will gradually increase across the region overnight ahead of a rapidly moving upper trough (and its associated cold front) that will be pivoting into the lower Ohio Valley/Mid-South.
(Rest of today through Thursday) A subtle shift in surface ridging will switch winds to a northeasterly direction during the early afternoon hours today. Temperatures will begin a slow upward climb today with forecast maximum high temperatures a few degrees warmer than yesterday with widespread highs in the low 80s. Rain chances will remain minimal however with the gradual moistening of the low-level boundary layer, a slight increase in cloud cover over land areas of South Florida could be realized by this afternoon. Although light northerly peninsular drainage flow will return once more overnight, temperatures will be about 6-8 degrees warmer at sunrise on Thursday compared to this morning. Rain chances will remain on the low end for the time being as there is still enough dry air in the mid-levels to prevent much in the way of convection.
131 PM CDT Wed Oct 18 2023 Key Message: 1) Cold front passing through will bring a chance for light precipitation through tomorrow, with breezy conditions. This will pass well north of the area, dragging a weak cold front through the region. Today and through the evening, we will see gusty southerly winds ahead of the cold front. Tomorrow, temperatures will be slightly cooler, with breezy northwest winds once again. Might need a light jacket, as damp conditions and a northwest breeze may make it feel a little cooler out there.
116 PM EDT Wed Oct 18 2023 A ridge of high pressure at the surface and aloft will be drifting east across the commonwealth today and bring with it, gradually improving weather conditions are expected through Thursday.
/13 (Now through Thursday) Zonal flow aloft above 700mb will return today and tonight as an upper trough (with embedded closed low pressure area) amplifies as it approaches the region from the northwest. This large upper trough will then settle over the eastern half of the CONUS and Gulf of Mexico on Thursday. Isolated light showers are expected to develop over the northern Gulf and coastal sections of the Florida Panhandle Thursday morning due to over- running along the western periphery of the low-level ridge. The beaches and barrier islands should only dip into the low to mid 60s. High temps will be slightly warmer Thursday, and should range from 75 to 80 degrees.
A building upper ridge will support dry conditions with mostly clear skies, light winds, and above normal temperatures.
Issued by National Weather Service Cleveland OH 355 PM EDT Wed Oct 18 2023 High pressure off the New England Coast will bring dry and warmer weather to the region Thursday.
239 PM CDT Wed Oct 18 2023 Key Messages: - Showers exit this evening - Drier with above normal temperatures Thursday An upper level low will continue to exit to the southeast through early this evening. The waa and good mixing will see temps climb into the 60s and 70s about 15 degrees warmer than climo norms.
