948 AM CDT Mon Sep 14 2020 High pressure will bring quiet weather and seasonable temperatures to the region for the next few days. Broad high pressure stretched from northern MN south into northern IL at 06z, bringing cooler air to central IL.
530 AM EDT Mon Sep 14 2020 Canadian high pressure will build into the region the first half of this week.
Stratus is thinning generally southeast of I-64, as high pressure settles in from our north.
254 PM MDT Mon Sep 14 2020 Latest GOES satellite imagery shows the region sitting under a dominant high pressure system today while gusty winds into the mid 20 mph range and low RH values to warrant Red Flag Warning across FWZ 303 for portions of Carbon and Albany County until 8 PM MDT. Another warm day in store for Tuesday with again dry conditions though modeled winds still seem on the low side that required some manual updating especially given current conditions today. A deepening mid/upper level trough over southern Canada will push the ridge to the west over the Intermountain West.
Less numerous showers are expected on Tuesday as the low-level trough moves further south and away from the area, however, moisture will continue to remain above normal. Less cloud cover is also expected so the combination of daytime heating and the higher than normal moisture should result in diurnal induced convection over land. With less cloud cover expected, temperatures should be a little higher with highs expected to rise into the lower 90s.
High pressure aloft will remain centered across the interior west through midweek. This high pressure will maintain above normal temperatures and dry conditions for the next several days. An upper level trough moving east through the region will bring cooler temperatures to the area by this weekend. The local area remains oriented along the western periphery of strong ridging centered over the southern plains region.
North winds in the low levels are likely getting a small boost from the strengthening of Sally to our distant east. In lieu of better rain chances advertised previously, the potential bright side is that humidities and possibly the low temp may be nudged downward through Tuesday night.
257 PM MDT Mon Sep 14 2020 Day started off way colder than expected with temperatures by noon barely reaching the low 60s.
312 PM EDT Mon Sep 14 2020 Seasonably cool temperature will moderate slightly through mid week, but expect cooler weather thereafter. Localized, and brief patchy frost is possible immediately before dawn for locations in northeast PA and in valley locations within the eastern ridges, especially Canaan Valley.
High pressure is expected across the area through Tuesday night.
312 PM EDT Mon Sep 14 2020 Synopsis/Discussion/Marine - Warming up the next few days - Significant cool down for the end of the week - Little potential for rain through the period - Warming up the next few days Strengthening south to southwesterly winds tonight into Tuesday will advect a warmer airmass into the CWA.
Cold front will sneak into the area today, and may allow for some lift to generate some showers, mainly in the far southern zones.
Ahead of the low will continue to see warm advection and southerly winds. Trailing trough or wind shift will slide south across the area tomorrow morning with winds becoming northerly during the daytime from NW to SE across the area. Will see a good gradient with highs in the low 80s in the south ahead of the wind shift and upper 60s in the Devils Lake basin behind the trough.
245 PM CDT Mon Sep 14 2020 18Z surface data has high pressure from the Great Lakes into the central Plains with a warm front running from southern Wisconsin into the Dakotas. Dew points were in the 50s north of the warm front with 60s south.
1144 AM MDT Mon Sep 14 2020 Overnight WV/IR satellite imagery showed a broad mid/upper level ridge centered over the Rocky Mountains with rather dry air aloft. The warm and dry weather pattern will persist through the short term under the influence of the mid/upper level ridge. 700mb temperatures of 10 to 14C will yield afternoon maxima in the 80s to lower 90s, with 60s and 70s for the higher terrain. A deepening mid/upper level trough over southern Canada will push the ridge to the west over the Intermountain West.
The latest runs of the HRRR continue to show the potential for an isolated shower or thunderstorm across far southeast Oklahoma this afternoon, so will keep the low pops in that area.
231 PM EDT Mon Sep 14 2020 Canadian high pressure will build into the region the first half of this week.
233 PM CDT Mon Sep 14 2020 Temperatures have warmed into the low to mid 80s early this afternoon under mostly to partly sunny skies. Due to the increase cloud cover, have highs generally 5 or so degree cooler than today in the low to mid 80s. Therefore, kept PoPs on the lower side for Tuesday as well.
Weak upper level high pressure will build across the Four Corners early on in the period.
1125 AM MDT Mon Sep 14 2020 Water vapor shows upper ridge building into the Northern Plains with a ridge topping wave moving eastward along the Canadian border. Dry cold front works through late tonight and early Tuesday shifting winds to the north, although highs on Tuesday may only be a few degrees cooler. Flow aloft becomes northwesterly mid/late week as trof deepens over the Great Lakes and ridge amplifies over the Intermountain West.
Overall, high pressure will shift through the eastern Lakes to the eastern seaboard this period. Meanwhile low pressure will quickly scoot from the northern Plains through the Lake Superior region into Canada. the resultant gradient will result in increasing southwest winds with warmer air getting pulled into srn WI. A trough/week cool front will then settle into northern and eventually central Wi Tuesday night.
357 PM CDT Mon Sep 14 2020 The warm front that was responsible for some patchy fog this morning across far northern Nebraska has slowly moved northward into central South Dakota this afternoon. RH values will drop into the lower teens to near 10 percent behind this front in areas west of Highway 61.
As for temperatures, lows tonight will be in the upper 50s to around 60, with some colder spots in the low to mid 50s across the eastern Ozarks. Highs Tuesday afternoon will top off in the lower 80s.
A broad upper level high will remain anchored over the southern Rockies this week keeping weather systems north of the Permian Basin. Models are showing a weak low getting cut off within this high pressure system and remaining in the area until later this week when it moves east. It is a little surprising that models are not showing more precipitation with this feature, though that is likely due to dry air in the lower levels being advected in from northeasterly flow around high pressure to our north and lower pressure in the Gulf of Mexico increasing stability.
The low level warm air advection will boost daytime highs into the 70s.

Most of the convection associated with the low to mid level trough axis has remained along the lower Texas coast into the lower Texas coastal waters this morning. The low to mid level trough axis is expected to drift westward into the Coastal Bend this afternoon.
A mid level trough is producing partly cloudy skies across the area but the bulk of the rain associated with the trough is back off to the west across the Davis Mountains and Trans Pecos. Overnight, expect temperatures to fall back into the lower to mid 60s, with even a few upper 50s possible across western portions of the area. Afternoon highs will top out in the low to mid 80s.
1207 PM CDT Mon Sep 14 2020 High pressure will bring quiet weather and seasonable temperatures to the region for the next few days. Broad high pressure stretched from northern MN south into northern IL at 06z, bringing cooler air to central IL.
Mid to upper level ridging builds in across the central CONUS over the next couple days which will lead to a gradual warming trend.
The high pressure system will slide eastward over New England while maintaining a nose into the Mid Atlantic southern Appalachian region.
222 PM EDT Mon Sep 14 2020 Canadian high pressure will build into the region the first half of this week.
Another mild and quiet day is anticipated for Tuesday with highs reaching the lower 80s.
Upper level analysis places broad ridge over the Rockies into the plains. Some high clouds lifting over the ridge continue to pass through our area. The smoke has had some influence on temperatures today, as we have remained cooler than expected. Ridge breaks down over our area, though will strengthen over the western United States.
The peak into autumn weather is courtesy of northeast surface flow around a large area of high pressure over the Great Lakes that continues to reinforce the drier air mass that moved in behind a cold front that slowly crossed the area yesterday and overnight.
It will be breezy ahead of a cold front on Tuesday.
1130 AM MDT Mon Sep 14 2020 High pressure will remain overhead early this week. High pressure will remain over the the forecast area through most of the work week bringing mainly dry conditions and unseasonably warm temperatures to the region.
1241 PM CDT Mon Sep 14 2020 North to northeasterly flow aloft will persist Monday into early Tuesday as the mid-level ridge stays locked in over the western CONUS.
312 PM EDT Mon Sep 14 2020 High pressure provides cooler and drier air through Tuesday.
Tranquil conditions will continue through tonight into Tuesday as a zonal flow persists under weak ridging aloft stretching from the Intermountain West into the Western High Plains. With little change to the general air mass across the high plains, look for lows back down into the 50s(F) tonight. Indications are that this colder airmass will slide southeast, away from the western Kansas region as Pacific trough will push into the West, allowing for the development of some southwest flow aloft to eventually overspread the Rockies and adjacent High Plains.
Tranquil conditions will continue through tonight into Tuesday as a zonal flow persists under weak ridging aloft stretching from the Intermountain West into the Western High Plains. With little change to the general air mass across the high plains, look for lows back down into the 50s(F) tonight.
This along with a slight increase in near surface moisture, will result in overnight lows a little warmer than this morning.
120 PM EDT Mon Sep 14 2020 High pressure will persist over the region into Tuesday but it will be shifting to eastern NY state.
A cold front begins to move through the area late Tuesday afternoon through the evening, with winds remaining somewhat breezy and turning to the north behind the front.
GOES water vapor imagery currently shows a broad ridge across the CONUS, with a mid-level trough west of Washington state over the Pacific Ocean. This smoke has worked to introduce a haze overhead most of the CONUS and has acted similarly to high cirrus causing surface temperatures to be slightly cooler than modeled.
1114 AM MDT Mon Sep 14 2020 The high pressure center continues to be positioned over south- central Wyoming today and will continue to bring very dry and unseasonably warm weather to the region. Temperatures today will be warmer than yesterday with 90 degrees possible across northeastern Johnson County and the Bighorn Basin. Tuesday will see the southwest flow become more zonal as a system to the north over Canada begins to push south into Montana and helps to flatten the ridge.
122 PM CDT Mon Sep 14 2020 While dry weather is expected through the next 36 hours, there will be some impactful conditions due to the confluence of an approaching slow-moving cold front from the west and high pressure centered over the northeastern CONUS.
410 PM EDT Mon Sep 14 2020 Though the tropics are extremely active with five tropical cyclones across the Atlantic basin right now, none of them presents a threat to the Keys.
Regarding the wildfire smoke: all indications are that with the arrival of a weak Canadian cold front tonight we will see surface- based smoke increase. Thickened surface smoke should continue thru tomorrow before finally improving late Tuesday night, with arrival of stronger backdoor cold front. Aforementioned front tonight will bring a slightly cooler and more humid day on Tuesday, with temps again impacted by smoke cover. Stronger push of Canadian air arrives Tuesday night, and this will lead to cooler temps (and less smoky skies) thereafter.
Convection has remained along the lower Texas coast and extending northeast into the offshore waters of the Middle Texas coast. HRRR model continues to show convection will develop over the coastal plains in association with the low to mid level trough moving inland this afternoon. Most of the convection associated with the low to mid level trough axis has remained along the lower Texas coast into the lower Texas coastal waters this morning. The low to mid level trough axis is expected to drift westward into the Coastal Bend this afternoon.
1232 PM CDT Mon Sep 14 2020 Current satellite imagery reveals quiet conditions across the region with latest observations showing temperatures hovering in the low to mid 50s. Forecast soundings are also fairly mixy which should allow for warmer temperatures and drier dewpoints to prevail. Otherwise, expect to see afternoon highs climb into the low to mid 80s east of I-29 and upper 80s to low 90s west of I-29 with the aid of enhanced WAA and radiational heating.
736 PM EDT Mon Sep 14 2020 High pressure provides cooler and drier air through Tuesday.
High pressure across the area continues to result in a southwest flow across the area.
524 PM MDT Mon Sep 14 2020 High pressure will remain overhead through much of this work week. As was the case the last few days, enough moisture and instability remain present to result in some building cumulus over the high terrain with some isolated showers popping up over the San Juans and Elk mountains. Since the lower atmosphere is so dry, anticipate more virga than anything with occasional breezy conditions.
637 PM CDT Mon Sep 14 2020 152 PM CDT Tomorrow looks to be mostly a repeat of today but a couple of degrees warmer in most locations. Upper level northwest flow will continue to advect smoke into the area from upstream fires, while southerly flow will gradually develop at the surface as a ridge axis stretching across the area from the central Great Lakes drops south overnight. Areas toward northeast Illinois will see the biggest change from today as winds off the lake are keeping afternoon temperatures in the lower 70s, while southerly flow Tuesday should allow for warming into the middle 70s.
500 PM MDT Mon Sep 14 2020 00Z TAF CYCLE Upper ridge axis extending through the Great Basin and over nrn CO to sag swd next 24 hrs. Weak sfc lee trough developing aft 15/12Z.
1034 PM EDT Mon Sep 14 2020 High pressure provides cooler and drier air through Tuesday.
There is a little hope for a change late this week as a weather system promises to bring cooler temperatures, some wind, and possibly some light precipitation.
The peek into autumn weather is courtesy of northeast surface flow around a large area of high pressure over the Great Lakes that continues to reinforce the drier air mass that moved in behind a cold front that slowly crossed the area yesterday and overnight.
711 PM EDT Mon Sep 14 2020 Seasonably cool temperature will moderate slightly through mid week, but expect cooler weather thereafter. Localized, and brief patchy frost is possible immediately before dawn for locations in northeast PA and in valley locations within the eastern ridges, especially Canaan Valley.
718 PM EDT Mon Sep 14 2020 Aviation - Warming up the next few days - Significant cool down for the end of the week - Little potential for rain through the period - Warming up the next few days Strengthening south to southwesterly winds tonight into Tuesday will advect a warmer airmass into the CWA.
High pressure is centered over the Great Lakes with ridging extending back across the mid Missouri Valley. On the southern periphery of this ridge axis, fair conditions are in place across central Illinois with calm or light E/NE winds.
301 PM MDT Mon Sep 14 2020 An upper level ridge will remain over the area through Tue, with warm and mainly dry weather expected. Low temps tonight should be in the mid 40s to lower 50s over the plains, with 30s and lower 40s in the high valleys. On Tue, highs should be in the 80s to near 90 over the southeast plains, and mostly in the 70s in the high valleys. Upper level high pressure remains over the area Wed/Thu, with warm afternoons and cool nights continuing. On Fri, ridge slides east and upper flow becomes more swly across the state as upper trough moves onshore in the Pacific NW.
605 PM MDT Mon Sep 14 2020 Update, cold front has moved through most of NE Montana at 00Z (6pm). Previous Discussion: Day started off way colder than expected with temperatures by noon barely reaching the low 60s.
High pressure will maintain above normal temperatures and dry conditions for the next several days. An upper level trough moving east through the region will bring cooler temperatures to the area by this weekend.
937 PM CDT Mon Sep 14 2020 (Issued 938 PM CDT Mon Sep 14 2020) Low pressure currently over ND will move across Lake Superior on Tue with breezy swly winds and warm temps for srn WI. No stratus or cumulus are expected due to much warmer temps aloft. The swly winds and mild temps will continue into Tue nt with a dry cold frontal passage on Wed. Overall, high pressure will shift through the eastern Lakes to the eastern seaboard this period. Meanwhile low pressure will quickly scoot from the northern Plains through the Lake Superior region into Canada. the resultant gradient will result in increasing southwest winds with warmer air getting pulled into srn WI. A trough/week cool front will then settle into northern and eventually central Wi Tuesday night.
Due to the increase cloud cover, have highs generally 5 or so degree cooler than today in the low to mid 80s. Therefore, kept PoPs on the lower side for Tuesday as well.
540 PM MDT Mon Sep 14 2020 Latest GOES satellite imagery shows the region sitting under a dominant high pressure system today while gusty winds into the mid 20 mph range and low RH values to warrant Red Flag Warning across FWZ 303 for portions of Carbon and Albany County until 8 PM MDT. Another warm day in store for Tuesday with again dry conditions though modeled winds still seem on the low side that required some manual updating especially given current conditions today. A deepening mid/upper level trough over southern Canada will push the ridge to the west over the Intermountain West.
817 PM EDT Mon Sep 14 2020 Canadian high pressure will build into the region the first half of this week.
406 PM MDT Mon Sep 14 2020 Current satellite pictures are showing some convective cloudiness over the high country, especially from I-70 southward. Models keep the upper ridge right over the CWA with very weak flow aloft tonight and Tuesday. The low level winds look to be normal drainage patterns tonight and weak upsloping on Tuesday. 5 C warmer than today's highs. An upper level ridge will remain just west of Colorado through the week.
Another mild and quiet day is anticipated for Tuesday with highs reaching the lower 80s. Otherwise a VFR forecast will prevail thanks to ridging aloft.
18Z surface data has high pressure from the Great Lakes into the central Plains with a warm front running from southern Wisconsin into the Dakotas. Dew points were in the 50s north of the warm front with 60s south.
Relative humidity is expected to drop into the lower teens and possibly single digits Tuesday afternoon, however winds look to remain below critical thresholds for fire weather conditions. Latest GOES satellite imagery shows the region sitting under a dominant high pressure system today while gusty winds into the mid 20 mph range and low RH values to warrant Red Flag Warning across FWZ 303 for portions of Carbon and Albany County until 8 PM MDT. Another warm day in store for Tuesday with again dry conditions though modeled winds still seem on the low side that required some manual updating especially given current conditions today. A deepening mid/upper level trough over southern Canada will push the ridge to the west over the Intermountain West.
652 PM EDT Mon Sep 14 2020 Canadian high pressure will build into the region the first half of this week.
903 PM CDT Mon Sep 14 2020 A forecast update is in place for warmer temperatures across ncntl Nebraska using the RAP model plus bias correction. A veering low level jet tonight should funnel warmer air into ncntl Nebraska. The new forecast is a few degrees warmer than the previous forecast in that region. The warm front that was responsible for some patchy fog this morning across far northern Nebraska has slowly moved northward into central South Dakota this afternoon. RH values will drop into the lower teens to near 10 percent behind this front in areas west of Highway 61.
Lows tonight should be close to values observed this morning, with the exception of portions of southeast Missouri and southwest Illinois which should be slightly cooler. Highs should reach into the low to mid 80s Tuesday, with lows dropping back into the mid 50s to low 60s Tuesday night.
330 PM MDT Mon Sep 14 2020 High pressure will remain overhead through much of this work week. As was the case the last few days, enough moisture and instability remain present to result in some building cumulus over the high terrain with some isolated showers popping up over the San Juans and Elk mountains. Since the lower atmosphere is so dry, anticipate more virga than anything with occasional breezy conditions.
Temperatures have warmed into the low to mid 80s areawide. At the surface, a lee trough is situated along the Colorado Front Range. Aloft, a ridge of high pressure continues to dominate the weather pattern across the majority of the United States. The previously mentioned lee trough will spread east tomorrow, bringing drier air yet calm winds to near Highway 27 by afternoon. No precipitation is anticipated as the dry pattern looks to continue with the dominant ridge of high pressure remaining situated over the Central US.
1045 PM EDT Mon Sep 14 2020 Currently - As Hurricane Sally nears the central Gulf coast a broad surface through lower level ridge has spread westward across Cuba and the Florida Straits. This evenings sounding indicated a slug of drier warmer air above ~960 mb. Short Term Update - The broad ridge will remain near the island chain through the overnight period. Forecast soundings indicate that while the lower level inhibiting layer will weaken some, it will remain. This along with the rather light flow and background ridging should result in isolated coverage for much of the forecast area. A broad ridge extending across Cuba and the Florida Straits will maintain light east to southeast breezes across Florida Keys waters.
845 PM MDT Mon Sep 14 2020 The clouds over the high country are dissipating and skies should remain clear overnight except for some smoke in the northern part of the CWA. The area remains under high pressure aloft and the forecast remains on track; no changes were made this evening. Current satellite pictures are showing some convective cloudiness over the high country, especially from I-70 southward. Models keep the upper ridge right over the CWA with very weak flow aloft tonight and Tuesday. The low level winds look to be normal drainage patterns tonight and weak upsloping on Tuesday. 5 C warmer than today's highs. An upper level ridge will remain just west of Colorado through the week.
628 PM CDT Mon Sep 14 2020 The warm front that was responsible for some patchy fog this morning across far northern Nebraska has slowly moved northward into central South Dakota this afternoon. RH values will drop into the lower teens to near 10 percent behind this front in areas west of Highway 61.
