423 AM EDT Mon Sep 11 2017 Mostly dry weather and warming temperatures is expected this week with high pressure continues over the area. The ridge breaks down on Tue but a dry WNW flow aloft continues. Tonight will see potential for fog development again as high pressure continues to provide light to calm winds and clear skies. Min temps expected to be a couple degrees warmer as the ridge axis begins to shift slightly east, with warming aloft. 925mb temps warm a bit more reaching near 18C around 21z so we are looking at the 70s to around 80 in the warmer valleys.
Upper level ridging over the Great Lakes early this week will help deflect the remnants of Irma westward as it gain latitude.
High pressure remains centered over the Great Lakes Region and Irma to the south.
/Issued 254 AM CDT Mon Sep 11 2017/ Drier airmass has filtered into the region this morning with temperatures running several degrees cooler compared to yesterday at this time. The mild weather will continue over the next few days a ridge axis at this surface remains. Otherwise, warming trend expected for the middle to latter part of the work week as upper ridge builds into the southern plains. The unseasonably warm weather will persist into the weekend with highs in the lower 90s across much of eastern Oklahoma/west- central Arkansas with gusty south winds.
208 AM EDT Mon Sep 11 2017 Mostly dry weather and warming temperatures is expected this week with high pressure continues over the area. The ridge breaks down on Tue but a dry WNW flow aloft continues. Tonight will see potential for fog development again as high pressure continues to provide light to calm winds and clear skies. Min temps expected to be a couple degrees warmer as the ridge axis begins to shift slightly east, with warming aloft. 925mb temps warm a bit more reaching near 18C around 21z so we are looking at the 70s to around 80 in the warmer valleys.
212 AM PDT Mon Sep 11 2017 Warmer weather will return for Monday and Tuesday as a ridge builds over the Inland Northwest.
402 AM CDT Mon Sep 11 2017 Not much of a shift in the forecast overall, as high pressure slowly loses ground to the dynamics of Hurricane Irma pushing into the southeastern United States. Clouds will help inhibit the cool down as overnight lows will be a few degrees warmer tonight.
Otherwise, will be quiet and warm and warmed temperatures up a few degrees with good mixing today and with southwest winds, this would argue for temperatures to be warmer by a few degrees.
557 AM CDT Mon Sep 11 2017 The quiet weather continues as mid-level ridging dominates the pattern and along with limited low and mid level moisture will result in another dry forecast through the entire work week.
127 AM EDT Mon Sep 11 2017 High pressure will remain over the area through early Tuesday. Forecast on track with dry conditions, mostly clear skies and somewhat warmer temperatures, especially on Monday as ridge axis shifts a touch more to the east.
1206 AM CDT Mon Sep 11 2017 High pressure over the Rockies and low pressure over the southeastern states will keep skies VFR with FEW cirrus and daytime cumulus.
125 AM EDT Mon Sep 11 2017 A large area of high pressure centered over the Upper Great Lakes will maintain control of our local weather into Tuesday. Very little change will occur Monday with a large area of high pressure (1024 mb) centered near the PA/NY border.
The low pressure center is expected to take a turn toward the NW and track across SW GA to N AL to West TN through Tuesday. The Wind Advisory will not be changed, although the northern and central Valley, SW VA, and northern Plateau will likely be on the low end of Advisory criteria (26 mph sustained or 40 mph gust).
409 AM MDT Mon Sep 11 2017 Strong and persistent mid/upper level ridging will persist over the Rockies through the period. A minor disturbance seen on GOES-16 WV imagery early this morning over southern WY and northern CO will meander slowly east and southeast today as it is trapped in the larger ridge aloft. With anemic flow at all levels of the atmosphere, convection should be dictated by terrain features so kept the best chances over the mountains and along the Cheyenne Ridge.
254 AM CDT Mon Sep 11 2017 Drier airmass has filtered into the region this morning with temperatures running several degrees cooler compared to yesterday at this time. The mild weather will continue over the next few days a ridge axis at this surface remains. Otherwise, warming trend expected for the middle to latter part of the work week as upper ridge builds into the southern plains. The unseasonably warm weather will persist into the weekend with highs in the lower 90s across much of eastern Oklahoma/west- central Arkansas with gusty south winds.
212 AM EDT Mon Sep 11 2017 High pressure will remain in control of our weather through Tuesday with mostly sunny days and chilly nights.
553 AM CDT Mon Sep 11 2017 Not much of a shift in the forecast overall, as high pressure slowly loses ground to the dynamics of Hurricane Irma pushing into the southeastern United States. Clouds will help inhibit the cool down as overnight lows will be a few degrees warmer tonight.
Now that the precipitation has primarily moved out, dry and warm weather is expected for the next several days as an upper ridge axis builds onto the Central Plains. Through the middle of the workweek, a continuation of the warm and dry weather will persist under the influence of the upper ridge axis in a fairly blocked pattern with a couple of low pressure systems off the west coast and eventual remnants of Irma to the east lifting north to Kentucky.
Furthermore, the breezy cool and dry air will maintain temps in the lower 80s across the FA, which is some 5-7 degrees below normal.
/issued 1148 PM EDT Sun sep 10 2017/ An upper level trough is evident on water vapor satellite imagery to the northwest of Hurricane Irma.
/issued 315 AM CDT Mon Sep 11 2017/ An upper high continues to dominate the region and will help keep Irma and its associated moisture well east of the FA.
Dry air will move into the area today into Tuesday warming up temperatures into the low 90s across South Florida. Upper level ridge over the Atlantic will gradually build over South Florida returning the easterly afternoon thunderstorms through the end of the week.
A strong pressure gradient will develop over the region later this afternoon and evening as surface pressure differences between Irma and high pressure to the northwest increase.
626 AM EDT Mon Sep 11 2017 High pressure over the eastern Great Lakes will weaken on Monday, though dry conditions will remain in place over the Ohio Valley. Today will be one last day under the blocky ridging that has enveloped the southern Great Lakes over the weekend.
High Pressure and Clouds. Pattern Forecast: Main focal point across the CONUS at the start of the period continues to be the remnants of hurricane Irma centered across the lower Mississippi valley. Primary Forecast Concerns/Challenges: Little in the way of sensible weather across northern Michigan this week with high pressure overhead.
346 AM CDT Mon Sep 11 2017 There are numerous convective elements showing up on radar this morning, however a quick check outside and while interrogating KPIR/KABR ceilings/BUFKIT soundings, this must be all above 12-15kft and at or above the freezing level, and as such anticipate much if not all is evaporating before reaching the surface. A wind shift is occurring across the area as well, associated with approach of high pressure that will move across North Dakota today. Tuesday will see a return of southerly low level flow as the high moves east.
While hurricane Irma is pounding south Florida, a large sprawling high pressure was situated in the Great Lakes. No real changes through Monday as the high pressure roams the Great Lakes, while providing mostly clear skies. Highs slightly warmer Monday in the lower half of the 70s most areas. Continued pleasant late summer weather across northern Michigan through midweek as ridging at the surface and aloft remains in control.
234 AM CDT Mon Sep 11 2017 Latest water vapor satellite imagery shows upper level ridge over the southern Rocky Mountains/Great Lakes Region. With upper level ridge over the forecast area mostly clear skies were seen per latest infrared satellite imagery. Subsidence under the ridge will continue to allow for dry weather and mostly sunny skies across the forecast area.
Warm and dry first half of the week, then much cooler and The next couple days will be warm and dry for this time of year under a low amplitude ridge. This low amplitude will also allow stronger winds to impact far northwest Montana, but mainly at the mid and upper elevations. The ridge is expected to weaken some late Tuesday allowing some unstable and moist air to work its way up from the Great Basin and into central Idaho and southwest Montana.
128 AM EDT Mon Sep 11 2017 High pressure centered over the eastern Great Lakes will gradually weaken through the day on Monday. Lows tonight will be in the mid 40s nw to the lower 50s southeast. The models are in general agreement taking the center of the low associated with Irma into northern Georgia/Alabama through Monday night. Generally expect highs on Monday to be in the lower 70s across the area.
211 AM MDT Mon Sep 11 2017 Water vapor shows rather flat upper ridge over the Northern Rockies and Northern Plains. At the surface, low center is located over south central SD with trof extending into eastern CO. Flat upper ridge expected to remain in place through mid week, leading to very warm temperatures. Upper level trof will dig through the Pacific Northwest during the second half of the week.
135 AM EDT Mon Sep 11 2017 High pressure will maintain dry conditions through the start of the week before rain chances return with approaching low pressure. Mainly clear skies are expected overnight under high pressure. Dy conditions under high pressure will continue through much of Monday and Monday night, with only high clouds increasing in advance of the remnants of Irma late.
1126 PM MDT Sun Sep 10 2017 Under the upper level ridge that is over the state, a weak disturbance will be slowly drift over CO tonight and Monday. High temps are expected to be a few degrees cooler on Mon, but still a little above average acrs the southeast plains, and around average in the high valley locations.
SW KS will remain under the subsident eastern periphery of a 592 dm upper high centered near Colorado, allowing for few clouds and temperatures several degrees above normal. Kept temperatures several degrees above MOS guidance, with most locations achieving the lower 90s.
220 AM EDT Mon Sep 11 2017 High pressure moves off the New England coast Monday.
258 AM CDT Mon Sep 11 2017 High pressure ridge from MI to MO bringing clear skies and light winds to the dvn cwa. High pressure ridge surface and aloft will extend from the northeast United States to the Corn Belt in the short term. Highs will be in the mid to upper 70s with lows in the lower 50s. Area highs in the upper 70s to around 80F and lows in the lower 50s.
An upper ridge will reside over SE Oregon and SW Idaho today for dry conditions and above normal temperatures. The ridge will weaken tonight through Tuesday as a south-southwest flow imports moisture from the Great Basin, resulting in a chance of showers and thunderstorms - mainly near the Nevada border.
1220 AM CDT Mon Sep 11 2017 142 PM CDT High pressure to continue influencing the weather across the region, with quiet/dry weather expected through the period. Rodriguez 213 PM CDT Monday night into Tuesday, broad ridging will continue to be in place across the Great Lakes and New England with slightly below normal temperatures and dry conditions persisting.
Otherwise, will be quiet and warm and warmed temperatures up a few degrees with good mixing today and with southwest winds, this would argue for temperatures to be warmer by a few degrees. Models suggest that mid/upper level ridging and dry weather will continue to prevail through most of this week with zonal flow through srn Canada Monday slowly giving way to sw flow from the plains to the nrn Great Lakes as a trough digs into the wrn CONUS. Although there were some model differences with the mixing depth with the developing subsidence inversion, temps closer to the higher end of guidance seemed more reasonable over inland locations.
synoptic scale pattern doesnt change much during the day with the forecast area remaining under 590-592dm upper high centered along the Colorado front range. During the night the upper high shifts slightly west/southwest as remnants of Irma move northwest into parts of Alabama. 850mb temperatures warm another 2F to 3F across the area supporting highs in the low to mid 90s. synoptic pattern changes little with the forecast area under upper ridging in between remnants of Irma centered near Tennessee and low pressure near/just off the southwest California coast.
534 AM EDT Mon Sep 11 2017 High pressure will maintain dry weather today. Periodic unsettled weather is expected the rest of the week with slow moving low pressure. Mostly sunny and dry weather is expected today under high pressure. Cirrus advancing N well ahead of Irma should continue to partially erode as it encounters and upper high and dry air aloft as observed on the 00Z PIT sounding. Dry air in place and the considerable distance from the low are expected to be limiting factors for rainfall.
A very similar day to yesterday, just a few degrees warmer. High pressure continues to dominate the weather pattern over the Great Lakes.
Looking at highs ranging from the mid 70s to around 80 in the normally warmer spots from downsloping. Weak pres gradient should once again allow for good radiational cooling, but given a warmer start, and slight increase in dwpts through the afternoon, mins will likely only fall into the low- mid 50s in the coolest spots, mid-upper 50s elsewhere. W winds and a warmer start (hence modified) will lead to highs in the low to mid 80s with a few spots sliding into the upper 80s. Comfortable dwpts still however, as mixing should keep them in the low-mid 50s. This energy is expected to induce a northern stream trough across the Great Lakes from a nearly zonal flow across southern Canada, and eventually approach our region late this week.
309 AM EDT Mon Sep 11 2017 High pressure is settling in currently and will stick around for at least the first half of the week. A warm front associated with the remnants of Irma will bring some moisture northward by late week possibly producing a few showers. No rain is expected and with upper low pulling E. That should put a fairly large area in the low to maybe mid 80s in the favored warm spots.
Highs today are expected to rise into the lower to middle 70s. Increased moisture on the backside of the high will bring an increased chance for patchy fog across the area. Even warmer temperatures are expected on Tuesday as dew points approach summer like levels around 60 degrees across central and east-central Wisconsin. Afternoon highs are expected to rise to around 80 degrees away from Lake Michigan, with cooler temperatures in the lower to middle 70s closer to the lake. Despite the increased dew points, dry weather is expected to last into Tuesday as moisture in the middle and upper levels remains paltry with the high over the Great Lakes region.
Britt Remnants of hurricane Irma will be moving into the lower Tennessee Valley on Tuesday.
406 AM CDT Mon Sep 11 2017 As of 08z Monday morning, the pesky upper low across the northern Plains has been absorbed by a northern stream trough across Manitoba. In association with the upper level trough, a cold front has pushed into the Dakotas. Mid level ridge has expanded across much of the central Plains, placing the forecast area in northernly mid level flow.
303 AM EDT Mon Sep 11 2017 High pressure will maintain dry weather today. Periodic unsettled weather is expected the rest of the week with slow moving low pressure. Mostly sunny and dry weather is expected today under high pressure. Cirrus advancing N well ahead of Irma should continue to partially erode as it encounters and upper high and dry air aloft as observed on the 00Z PIT sounding. Dry air in place and the considerable distance from the low are expected to be limiting factors for rainfall.
300 AM EDT Mon Sep 11 2017 High pressure will maintain dry weather today. Periodic unsettled weather is expected the rest of the week with slow moving low pressure. Mostly sunny and dry weather is expected today under high pressure. Cirrus advancing N well ahead of Irma should continue to partially erode as it encounters and upper high and dry air aloft as observed on the 00Z PIT sounding.
350 AM MDT Mon Sep 11 2017 Upper ridge of high pressure remains parked over Colorado with light flow aloft but a bit of a westerly flow over northern Colorado. Temperatures will be a bit cooler today with cloud cover and slightly cooler low levels.
A cold front has moved into northwest Minnesota and will continue east into northeast Minnesota by early afternoon then continue east and weaken into this evening. We added a chance for showers this morning ahead of the cold front over parts of northeast Minnesota into far northwest Wisconsin. High pressure will build in behind the front and provide mostly clear skies tonight. Lows will range from the lower forties to around 50. Mostly sunny skies are expected Tuesday as the high sinks southeast.
A relatively flat upper ridge will hold over the Pacific Northwest through tonight for dry weather and warmer temperatures.
Mid/upper level ridge builds from the Rockies into Northern Mexico while a deepening mid/upper level low drifts from the southeastern states into the lower and middle Mississippi Valley with tropical cyclone Irma. Little change in temperatures is expected today with a warming trend beginning on Tuesday as a thermal ridge begins to build into our area.
High pressure will remain over the area for the early part of the week. A series of storm systems will bring cooler and wetter conditions to Utah and southwest Wyoming for the middle to latter part of the work week before drier conditions return for the upcoming weekend.
406 AM CDT Mon Sep 11 2017 (Today and Tonight) Not much change to the forecast for the next 24 hours as an upper level ridge remains centered near the Four Corners area, and Irma makes progress northward into Georgia.
By Wed 85h thermal ridge will amplify and expand ewd, even moreso Thur and probably Fri too.
A weak trough axis is moving towards the area, and ahead of it a weak temperature and theta-e surge around 700mb is producing an area of clouds and a few showers with high bases. This extra cloud cover should keep temperatures a little warmer than this morning, with lows in the 50s and low 60s. The cold front now located over Manitoba and western North Dakota will move slowly east tonight and slide across the forecast area on Monday. Highs to be slightly warmer than today, with highs in the middle and upper 70s.
An upper ridge over the region will shift inland today and Tuesday.
640 AM EDT Mon Sep 11 2017 Warmer temperatures this week with highs mainly in the 70s. It will be warmer today as 850 mb temperatures are forecast to rise to 13 to 15 degrees C. Mixing is not expected to be deep enough to reach 850 mb due to the strong high pressure overhead. However, highs expected to be in the 70s with mid and upper 60s across the higher terrain of the western Adirondacks, eastern Catskills, southern Vermont into the Berkshires.
325 AM CDT Mon Sep 11 2017 The quiet weather continues as mid-level ridging dominates the pattern and along with limited low and mid level moisture will result in another dry forecast through the entire work week.
while high pressure centered over the Great Lakes is ridging swwd over the wrn Gulf region. As the low center tracks into the lower Mississippi Delta tomorrow, will see wrap around moisture begin encroaching across mainly the nrn zones, primarily in the form of increased cloud cover. This surge of nrly flow will also lead to slightly cooler max temps next couple of days.
An area of low pressure is currently located over Saskatchewan with a cold front along the western Dakotas. An are of high pressure will slide across North Dakota on Monday with winds shifting to the northeast. The core of this high pressure is very dry with dew points dropping into the 40s and 50s by the afternoon hours. Upper ridging over the region on Tuesday will draw up 850mb temps in the mid +20sC.
Slightly cooler temperatures are forecast today, with much cooler weather expected by midweek and beyond. An upper low is currently centered about 350 miles west of San Diego. A disturbance rotating around this low is triggering widespread showers and isolated thunderstorms across Monterey and San Benito Counties, extending westward offshore. Showers and thunderstorms may increase by late this afternoon and early evening as the next impulse rotating around the upper low arrives over central California.
643 AM EDT Mon Sep 11 2017 High pressure will remain across the region today and Tuesday. High pressure will return for the weekend. High pressure will remain overhead today. Temperatures will be several degrees warmer at H8 today and do not think any of the cloud cover will have much impact on highs. Therefore have temperatures warming today into the lower/mid 70s.
No significant changes seen across the CWA over the next couple days with an upper high pressure area being the main weather factor for the region. Continued warm Monday through Tuesday with the upper high building some over the region.
222 AM MST Mon Sep 11 2017 Dry air moving into the region will end rain chances starting today while also bringing warmer temperatures through the middle of this week.
207 AM CDT Mon Sep 11 2017 142 PM CDT High pressure to continue influencing the weather across the region, with quiet/dry weather expected through the period. Rodriguez 213 PM CDT Monday night into Tuesday, broad ridging will continue to be in place across the Great Lakes and New England with slightly below normal temperatures and dry conditions persisting.
343 AM EDT Mon Sep 11 2017 High pressure will remain across the region today and Tuesday. High pressure will return for the weekend. High pressure will remain overhead today. Temperatures will be several degrees warmer at H8 today and do not think any of the cloud cover will have much impact on highs. Therefore have temperatures warming today into the lower/mid 70s.
331 AM EDT Mon Sep 11 2017 High pressure will remain overhead through tonight.
Winds aloft are still expected to be rather strong, and gusts of 50-55 mph remain possible especially over the higher terrain. Rainfall rates with Irma are not expected to be particularly impressive due to cooler air wrapping around the western side, so flash flooding is of minimal concern even with storm total amounts up to 4.
327 AM CDT Mon Sep 11 2017 High pressure over OK extending down into TX Hill Country with north to northeasterly flow across SETX this morning.
347 AM EDT Mon Sep 11 2017 High pressure over the eastern Great Lakes will weaken on Monday, though dry conditions will remain in place over the Ohio Valley. Today will be one last day under the blocky ridging that has enveloped the southern Great Lakes over the weekend.
413 AM MDT Mon Sep 11 2017 High pressure aloft will stay in place over the region with Irma tracking up the east coast and a closed low remaining off of the coast of California Monday and Tuesday.
Winds will be lighter than last night especially near the axis of the trough.
Unseasonably mild temperatures are expected over the next several days as the upper ridge across the west expands east. Quiet weather pattern will continue into mid week, as upper level ridging dominates much of the central and western US.
