954 AM EDT Sun Sep 20 2020 High pressure over the eastern Great Lakes will build to New England through Monday.
601 AM EDT Sun Sep 20 2020 High pressure will remain in place through the middle of the week with dry conditions and gradual warming. High pressure ridging will start building in from the south today and temperatures will begin to moderate.
324 AM MDT Sun Sep 20 2020 Upper level trough continues to push through the region early this morning with mid-level clouds as across eastern Wyoming and western Nebraska.
534 AM EDT Sun Sep 20 2020 Dry and cool conditions will prevail throughout the week under high pressure.
618 AM EDT Sun Sep 20 2020 High pressure will remain in place through the middle of the week with dry conditions and gradual warming. High pressure ridging will start building in from the south today and temperatures will begin to moderate.
/Issued 247 AM CDT Sun Sep 20 2020/ Surface ridging conditions will hold today, with another sunny (but hazy) day in store. Expect afternoon temperatures near or perhaps a touch warmer than yesterday.
Mainly zonal flow for the next few days will keep generally tranquil conditions in place while temperatures moderate slowly through the week as weak ridging gradually tries to build back in.
1108 AM MDT Sun Sep 20 2020 18Z TAF CYCLE Upper ridge axis extends from west to east over NM. Otherwise high level smoke/haze will persist with the 12Z HRRR Smoke model indicating the higher impact areas would be over the ern and srn halves of NM. High pressure over New Mexico will lead to more nice weather today with warm temperatures, low humidity, and light winds.
232 PM CDT Sun Sep 20 2020 An upper-level ridge has moved into the Midwest today with the ridge axis cutting through the Quad State. will continue to see dry weather as the high pressure center sets up over the Southern Appalachians early in the week, upon which winds locally will shift to a more southeasterly direction.
231 PM EDT Sun Sep 20 2020 High pressure will build south into the region, providing dry and cool conditions through the middle of the week.
1231 PM EDT Sun Sep 20 2020 Strong Canadian high pressure will ensure cool, dry, and fall- like weather today under mostly sunny skies. High pressure will remain dominant across the Northeast into Monday night before tropical system Teddy closes in on coastal Main, and the Canadian Maritimes.
However, skies should be mostly clear as surface ridging remains in place over central Illinois.
1151 AM EDT Sun Sep 20 2020 Dry, cool conditions will prevail through much of the week amid high pressure. Upper-level ridging between an Atlantic tropical system and a trough in central Canada will maintain high pressure, light wind and generally clear sky in the Upper Ohio Valley. Influence of the srn-stream trough may spread into the Ohio Valley by late in the week, but how this trough will interact with nrn-stream features is unclear at best. VFR and light NE-E wind are expected through the TAF period under dry high pressure.
Aloft, an upper ridge will be located over the Srn plains today providing NW flow across the Ern two-thirds of the CONUS. This ridge will slowly work its way Ewrd, pushing E of the MS River by Monday. PoPs return to Srn AR Monday afternoon along and S of a warm front defined by much higher moisture content rather and large increase in temperatures.
Increasing low level moisture ahead of Tropical Storm Beta will likely spread into the area during this time frame, interacting with a developing upper low over Kansas/Oklahoma.
1216 PM EDT Sun Sep 20 2020 High pressure will remain in place through the middle of the week with dry conditions and gradual warming. High pressure ridging will start building in from the south today and temperatures will begin to moderate.
With dry atmosphere, diurnal range will also remain on the large side with lows mostly in the low 50s and highs rebounding into the upper 70s to mid 80s.
Cold front that moved through the area last night is currently across northern Colorado. Same can not be said for Monday as front shifts east and we see warmer temperatures.
218 PM EDT Sun Sep 20 2020 Strong Canadian high pressure will ensure cool, dry, and fall- like weather today under mostly sunny skies.
The boundary that these light showers developed on will weaken over the area tonight, with high pressure settling in over the region Monday into Monday night, keeping conditions dry. An upper trough will slide east of the area tonight as well, and with the flow becoming more zonal, may see a bit of a break in the high level smoke activity tonight and Monday as well. Low temperatures tonight will be in the lower to mid 50s, with highs on Monday in the upper 70s to lower 80s. Lows on Monday night will again be in the lower to mid 50s.
1259 PM CDT Sun Sep 20 2020 For mid-day update have adjusted precipitation chances a bit over the east where the line of showers continues to quickly advance, and over the northwest where some showers affiliated with an upper level low continue to gradually approach the area. Upper level low will bring a weak cold front across the region today, with the results being a few showers and gusty winds while temperatures remain mild in the 70s. A developing upper low is currently placing a trough in eastern MT and parts of western ND. Speaking of winds, models forecasting strong winds at the 850 mb layer as the low becomes tightly wrapped and stacked this afternoon. Lows tonight may be slightly cooler in the 40s and 50s, but still near normal.
High pressure at the surface and aloft will be the dominant force across the area through at least mid week, keeping the weather dry and temperatures near or slightly above seasonal normals.
319 PM EDT Sun Sep 20 2020 A stalled frontal boundary is in place across the southern half of the peninsula with a weak and shallow area of low pressure moving west along the boundary over central Florida this afternoon.
Patterson (Issued 344 AM CDT Sun Sep 20 2020) Today through Monday: Strong high pressure centered over the northeast United States will remain fairly stationary through Monday, while weakening a bit. This high will largely keep clouds away across southern Wisconsin through tomorrow, while southerly winds here on the west side of the high will result in warming temperatures.
Main challenge for the short term will be approaching upper trof, and pcpn potential today. Very nice looking trof in wv imagery this morning over the northern Rockies. This trof will shift northeast today, as a s/w within the trof moves across the Dakotas. Once upper trof moves off to the east toward evening, am expecting the rest of the forecast to be quiet/dry. The elevated smoke of recent days will probably get pushed off to the east later today as upper trof crosses the region and shifts the mid level winds to more of a westerly direction.
High pressure was anchored over southern Ontario and southern Quebec. A warm front stretched from near the western North Dakota low southeastward into western Iowa. Convergence and isentropic forcing for ascent associated with the warm front will support a slight chance to chance POPs for showers or thunderstorms late afternoon and tonight.
A weak cu field has developed over the area, associated with a weak surface pressure trough. Tranquil weather will persist on Monday as both surface and upper level high pressure remain over the area. Tropical Storm Beta is expected to make landfall along the Texas Gulf Coast Monday afternoon and slowly lift northeast across the Lower Mississippi Valley through the end of the workweek.
This matches previous forecast thoughts/reasoning of localized light measurable amounts ahead of cold front through this afternoon.
131 PM EDT Sun Sep 20 2020 High pressure over the eastern Great Lakes will build to New England through Monday.
317 PM EDT Sun Sep 20 2020 High pressure will continue to extend across the area into the middle of the week. For tonight and Monday, a mid level ridge axis will push east across the Great Lakes and Ohio Valley while surface ridging continues to extend from the St. Lows tonight will generally range from the lower to mid 40s with highs on Monday in the lower to mid 70s. High clouds will increase from the southwest Monday night on the back side of the mid level ridge. Lows again will generally fall into the lower to mid 40s. The first portion of the extended remains quiet as mid-level ridging and dry air dominate the region.
313 PM EDT Sun Sep 20 2020 High pressure will remain in place through the middle of the week with dry conditions and gradual warming. Upper level ridging with high pressure shifting east allows our area to continue to stay dry through Monday. Expect slowly warming temperatures across the atmospheric column between today and tomorrow allowing for warmer nighttime lows (low 40s) tonight and warmer daytime highs (low to mid 70s) Monday.
Per observations, satellite imagery, and the HRRR-Smoke model, we have extended the haze in the grids through Monday, as remnant lower-mid tropospheric smoke will not change much as the lower and mid tropospheric winds will keep a direction similar to the orientation of the smoke axis across West Texas through Oklahoma and much of Kansas. Ahead of this trough, we may see an increase in southwesterly flow aloft, supporting warmer temperatures, perhaps into the lower 90s for highs (lower 60s for lows).
ESTOFS shows tide levels may approach 4 feet MSL for the high tide Monday evening.
325 PM EDT Sun Sep 20 2020 Expansive high pressure now extends from eastern Canada across the Great Lakes and into the southern Plains. With the center of this high over Quebec, cool/dry east-southeast flow persists over Se MI and has sustained sunny skies and cool temps. A mid level ridge over the western Great Lakes will move into the eastern Great Lakes Monday while folding over/dampening as a deep upper wave over Saskatchewan lifts across nrn Ontario Mon night. Se Mi will remain under the influence of this large low level anticyclone and associated dry air. High altitude smoke is slowly pushing toward Lake Mi and is expected to overspread Se Mi by Monday as the mid level ridge axis crests to the east, likely causing some hazy sunshine.
347 PM EDT Sun Sep 20 2020 A broad area of high pressure will be centered over New England on Monday then build westward to the Ohio Valley for the mid-week period. High pressure is centered over southern Quebec late this afternoon and will move to New England on Monday as the upper level ridge expands overhead. The very dry airmass will continue to favor a large diurnal spread with cool nights and temperatures dipping into the lower 40s.
356 PM EDT Sun Sep 20 2020 For the first time in days, we have a solid cloud line over the Lower Keys.
Deep layer overrunning moisture above the post cold frontal airmass overlying the area will continue to spread cloud cover and areas of generally light rain over much of the forecast area. Model guidance has temperatures Monday afternoon climbing into the low to mid 70s. Tonights lows are anticipated to fall generally in the low to mid 60s.
237 PM CDT Sun Sep 20 2020 Another pleasant afternoon is in store region-wide as temperatures gradually rise into the lower 80s.
245 PM EDT Sun Sep 20 2020 High pressure will drift nearby to the area for the foreseeable future. High pressure will continue to dominate the Northeast and Mid- Atlantic. With a strong inversion setting up and increasing flow above the inversion, this will yield increasingly southeasterly flow over the warmer lakes overnight. Additionally, based upon how low the inversion looks to set up, some of the higher spots along the Chautauqua Ridge will likely remain a bit breezier overnight. All of this said, even with a bit warmer night, frost and freeze headlines have still been issued for the interior Southern Tier and North Country where the growing season is still ongoing.
At the surface, lee troughing remains in place with Tropical Storm Beta southeast of the TX Coast.
308 PM CDT Sun Sep 20 2020 High pressure remained common across much of the Southern Plains this afternoon with some hazy skies to partly cloudy skies observed over Eastern Oklahoma and Northwest Arkansas. To the south of the area of high pressure. Dewpoints have begun to slowly rise this afternoon into the mid 50s to mid 60s and this moisture should keep temps tonight a little warmer compared to the previous couple of night with lows in the 50s to low 60s forecast. the mid level ridge of high pressure is progged to begin lifting northeast allowing for moisture from Tropical Storm Beta to begin streaming northward into the region as the system nears the Texas Coast.
Temperatures this afternoon where well into the 60s, with a few locations reaching into the lower 70s. Breezy conditions are expected again tomorrow as the region remains sandwiched between a high pressure system moving through the northeast US and a low pressure system tracking through southern Saskatchewan and Manitoba, Canada.
252 PM CDT Sun Sep 20 2020 An area of low pressure will move from southeast Saskatchewan today, to northwest Ontario Monday night. There is a low chance of some showers tonight as a negatively tilted short wave trof lifts through the region. High pressure is over the rest of the area Monday and covers the region Monday night.
138 PM EDT Sun Sep 20 2020 VFR conditions will persist through the forecast period as a strong high pressure remains in control of the region. The high will be centered east of the area keeping a south/southeasterly wind direction.
1101 AM EDT Sun Sep 20 2020 There are three main features on the weather map this morning: TS Beta over the northwestern Gulf of Mexico, a cold front across Central Florida, and Hurricane Teddy to the southeast of Bermuda. Model guidance has continued to trend slower in bringing the cold front and associated strong NE breezes into the coastal waters of the Florida Keys, with the major wind increase now delayed until Monday afternoon.
Temperatures today are expected to be similar to what we experienced yesterday as the mid level ridge remains over the area and flow through most of the atmosphere remains light and out of the north. Another chance for fog development with the clear skies, with the highest chances occurring the the sheltered valley locations.
As of mid-morning, skies remained clear and sunny and temperatures were warming up into the lower 60s in most locations. Expect clear skies and cooler than normal temps to continue today and tonight. Low-level thickness progs suggest max temps this afternoon will be about 2 deg warmer than Sat.
138 PM EDT Sun Sep 20 2020 High pressure will continue to extend across the area into the middle of the week. Temperatures will get a few degrees warmer than yesterday. Temperatures will be in slow moderating with both lows and highs being a few degrees warmer than the previous 24 hours.
249 PM EDT Sun Sep 20 2020 With strong high pressure centered over the NE states at 1035mb and ridging down the spine of the Appalachians into the Carolinas and the local area, just a beautiful early fall day is unfolding. This is around 5 to 10 degrees cooler than the seasonal average. Strong high pressure and a very dry mid level is keeping temps down and rain out of the forecast for most of the week.
918 AM MDT Sun Sep 20 2020 Expect a partly to mostly sunny and cooler day with windy conditions. Temperatures will only reach the low 70s, and humidities not get below 20 percent. Temperatures will rebound a bit on Monday as weak upper ridging and downslope winds returns to Montana. Temps will return to the low 80s and humidities back to the upper teens, though winds will stay relatively light.
223 PM EDT Sun Sep 20 2020 High pressure maintains dry weather and plenty of sunshine for much of this week. High pressure along with upper level ridging continue to keep mostly clear skies and dry weather for this period. Temperatures tonight will be chilly again, with lows down into the low to mid 40s in the lowlands and mid to upper 30s for the upper elevations. MOS guidance for the dewpoint temperatures in this area were also on the colder side, around the lower 30s for tonight. Tomorrow's high temperatures will continue to be below normal, similar to or just slightly warmer than today. Highs should be in the upper 60s to lower 70s for the lowlands and mid 50s to lower 60s for the highest elevations.
This is due to the strong high pressure that is centered over the northeastern CONUS. Southerly winds are expected to continue here on the west side of the high pressure, which will result in warming temperatures.
The winds will be strong enough over Lake Michigan to cause hazardous beach conditions across a portion of the coastline, primarily around/sough of Pt Betsie and west of the Mackinac Bridge.
Upper level trough continues to push through the region early this morning with mid-level clouds as across eastern Wyoming and western Nebraska.
122 PM CDT Sun Sep 20 2020 An upper level ridge is centered over the upper Great Plains this morning and will shift east during the day. Although cloud cover will increase as the trough moves through, precipitation chances are slim. Afterwards, the dominant pattern for the remainder of the forecast period is the upper level ridge.
1218 PM EDT Sun Sep 20 2020 High pressure will build south into the region, providing dry and cool conditions through the middle of the week.
It will be mild with highs in the lower to middle 70s.
The elevated smoke layer appears to be thin enough this afternoon to allow temperatures to already warm into the low 70s, have nudged up highs slightly to account for any additional warming this afternoon.
1230 PM CDT Sun Sep 20 2020 304 AM CDT An upper ridge axis centered along the mid and upper Mississippi River Valley this morning will drift to the northeastern U. through Monday while the area remains placed between high pressure over the eastern CONUS and broad low pressure across the western CONUS. A fairly thick area of western wildfire smoke trapped under the ridge will drift over the area today through at least Monday.
245 PM MDT Sun Sep 20 2020 Zonal upper flow remains across the northern tier of state after the upper trough moving east of the Rockies moves out across across the norther Plains tonight. The upper low getting pulled into the flow over the southern plains from the Gulf Coast region should remain far enough east of the region to not affect the forecast area directly.
315 PM EDT Sun Sep 20 2020 High pressure over New England will continue to be in place through the most of the week and expand into the southeastern United States. High pressure will be in place over New England leading to ideal radiational cooling both tonight and Monday night and a sunny Monday. Continued to go lower than model guidance by a few degrees with the lows overnight given the ideal conditions for radiational cooling. As for the lows tonight they should fall into the upper 20's and low 30's enough for frost formation across most of the area. Temperatures look slightly warmer Monday night but it's another favorable setup for radiational cooling and some frost.
111 PM MDT Sun Sep 20 2020 Water vapor shows upper low over southern SASK with nearly zonal flow extending from the Northern Plains westward through the Pac NW. At the surface, breezy westerly winds across our zones in wake of cold front that moves through early this morning, with temps in the 70s to lower 80 on the plains.
Over the northwest, a few light showers in cyclonic flow near the low are starting to sneak into the area. On Monday, low/trough pushes off to the east, but stronger pressure gradient remains over northern/eastern locations bringing a breezy day. Otherwise, quiet conditions expected as ridge builds in. Ridging over the area keeps weather quiet through the first part of the week.
140 PM EDT Sun Sep 20 2020 High pressure will drift nearby to the area for the foreseeable future. High pressure will continue to dominate the Northeast and Mid- Atlantic. With a strong inversion setting up and increasing flow above the inversion, this will yield increasingly southeasterly flow over the warmer lakes overnight. Additionally, based upon how low the inversion looks to set up, some of the higher spots along the Chautauqua Ridge will likely remain a bit breezier overnight. All of this said, even with a bit warmer night, frost and freeze headlines have still been issued for the interior Southern Tier and North Country where the growing season is still ongoing.
Temperatures were in the upper 60s to lower 70s with dewpoints mostly in the lower 40s. Winds were a bit stronger than the past several days due to the increasing pressure gradient behind high pressure, now over over southern Quebec. Tonight should see temperatures a few degrees warmer than last night due to slightly stronger southeast breezes. This results in lows from the mid 40s east to upper 40s in the far south and west, which is at the low end of guidance. Based on satellite trends, the high level smoke overhead may begin to thin out Monday. High pressure will remain anchored from the Ohio River Valley into the Northeast through mid week.
452 PM EDT Sun Sep 20 2020 High pressure will drift nearby to the area for the foreseeable future. High pressure will continue to dominate the Northeast and Mid- Atlantic. With a strong inversion setting up and increasing flow above the inversion, this will yield increasingly southeasterly flow over the warmer lakes overnight. Additionally, based upon how low the inversion looks to set up, some of the higher spots along the Chautauqua Ridge will likely remain a bit breezier overnight. All of this said, even with a bit warmer night, frost and freeze headlines have still been issued for the interior Southern Tier and North Country where the growing season is still ongoing.
1010 PM EDT Sun Sep 20 2020 High pressure maintains dry weather and plenty of sunshine for much of this week. high pressure providing dry weather tonight. High pressure along with upper level ridging continue to keep mostly clear skies and dry weather for this period. Temperatures tonight will be chilly again, with lows down into the low to mid 40s in the lowlands and mid to upper 30s for the upper elevations. MOS guidance for the dewpoint temperatures in this area were also on the colder side, around the lower 30s for tonight. Tomorrow's high temperatures will continue to be below normal, similar to or just slightly warmer than today. Highs should be in the upper 60s to lower 70s for the lowlands and mid 50s to lower 60s for the highest elevations.
731 PM EDT Sun Sep 20 2020 High pressure will build south into the region, providing dry and cool conditions through the middle of the week.
1040 PM EDT Sun Sep 20 2020 High pressure will continue to extend across the area into the middle of the week. In the high levels some few to scattered cirrus will drift across the region overnight. Tweaked the lows in rural areas down a degree or so based on dry air still over the fa. For Monday, a mid level ridge axis will push east across the Great Lakes and Ohio Valley while surface ridging continues to extend from the St. Highs on Monday in the lower to mid 70s. High clouds will increase from the southwest Monday night on the back side of the mid level ridge. Lows again will generally fall into the lower to mid 40s. The first portion of the extended remains quiet as mid-level ridging and dry air dominate the region.
746 PM EDT Sun Sep 20 2020 High pressure will continue to extend across the area into the middle of the week. For tonight and Monday, a mid level ridge axis will push east across the Great Lakes and Ohio Valley while surface ridging continues to extend from the St. Lows tonight will generally range from the lower to mid 40s with highs on Monday in the lower to mid 70s. High clouds will increase from the southwest Monday night on the back side of the mid level ridge. Lows again will generally fall into the lower to mid 40s. The first portion of the extended remains quiet as mid-level ridging and dry air dominate the region.
