843 PM EDT Tue Sep 10 2024 High pressure and ridging aloft will keep dry weather and above average temperatures in the forecast this week. KEY MESSAGES: - High pressure provides a mostly clear night, with seasonable temperatures. KEY MESSAGES: - Above average temperatures and dry conditions continue under high pressure. Confidence is high that above average temperatures will continue into Wednesday as the ridge axis advances over the Great Lakes.
723 PM EDT Tue Sep 10 2024 High pressure centered over West Virginia will move to New England and remain nearly stationary into the weekend. Low pressure from a tropical system will move into the mid Mississippi Valley by the weekend and weaken. Quiet late summer weather is expected this period as high pressure from the surface to aloft remains in control over the area. A weak surface pressure gradient will allow a lake breeze to develop Wednesday which will keep the northern half of the lakeshore counties a bit cooler. Overnight lows will cool into the lower to mid 50s except near 60 along the lakeshore. Flow should be quiet with an upper level ridge in place over the NE CONUS and accompanying large high pressure at the surface.
803 PM EDT Tue Sep 10 2024 High pressure will remain in control of our weather through the next several days, supplying plentiful sunshine and mainly warm weather. Coverage of fog in the typical river valleys is fairly uncertain as we have had a very dry day with dew points in the upper 30s to mid 40s in most places and some modest gradient flow will linger winds, especially in northern portions of Vermont further from the center of the high pressure area. A ridge of high pressure will remain in place over the region through this period, bringing dry weather and mostly sunny skies. This ridge will suppress Francine well to the southwest so the storm poses no threat to the area.
Expect daybreak readings to range from the low 40s in the coolest valleys of Sullivan County, to the mid 50s over parts of the Lower Susq Valley. Upper level ridging building over PA should ensure fair weather with nearly cloudless skies through the end of the work week. At the surface, high pressure is progged to pass east of New England, with ridging extending westward over PA.
644 PM EDT Tue Sep 10 2024 High pressure lasts through much of this week. Weak ridging surface and aloft over eastern NC this evening, yielding another dry/quiet day across the region. High pressure surface and aloft remains the dominant features controlling the weather across eastern NC for Wednesday. Maximum temps will be a degree or two warmer than today, low 80s with upper 70s expected along the coast/OBX. High pressure will continue to ridge into the area for much of the week bringing dry weather but also below normal temps and comfortable dew points.
A significant weather pattern shift is still expected for southeast Oregon and southwest Idaho, as a trough from the Gulf of Alaska is forecast to arrive by Wednesday morning. Strong upper-level dynamics are likely to bring showers and thunderstorms along and behind the cold front as early as sunrise Wednesday morning. Temperatures are expected to drop by about 15 degrees from today's highs, with breezy northwest winds following the cold front. However, there is still some uncertainty regarding the track of the low-pressure center.
732 PM EDT Tue Sep 10 2024 High pressure continues to bring dry conditions through the upcoming weekend.
541 PM EDT Tue Sep 10 2024 High pressure sustains dry weather through much of the work week, with a gradual warming trend.
1015 PM EDT Tue Sep 10 2024 High pressure sustains dry weather and above normal temperatures through much of the work week.

735 PM EDT Tue Sep 10 2024 High pressure sustains dry weather through much of the work week, with a gradual warming trend.
1046 PM EDT Tue Sep 10 2024 High pressure will remain in control of our weather through the next several days, supplying plentiful sunshine and mainly warm weather. Coverage of fog in the typical river valleys is fairly uncertain as we have had a very dry day with dew points in the upper 30s to mid 40s in most places and some modest gradient flow will linger winds, especially in northern portions of Vermont further from the center of the high pressure area. A ridge of high pressure will remain in place over the region through this period, bringing dry weather and mostly sunny skies. This ridge will suppress Francine well to the southwest so the storm poses no threat to the area.
728 PM EDT Tue Sep 10 2024 Cool and dry weather is expected through mid week as Canadian high pressure builds in from the north.
Low pressure is forecast to develop along the front offshore the GA/SC coast this weekend.
Warmer than normal temperatures will persist through the work week as mostly dry weather continues. Cooler temperatures for the upcoming weekend as precipitation chances return thanks to an infusion of tropical moisture. Expect similar temperatures tomorrow, maybe a degree or two warmer.
716 PM EDT Tue Sep 10 2024 High pressure will dominate the northeast and eastern Great Lakes through the weekend.
754 PM EDT Tue Sep 10 2024 High pressure and ridging aloft will keep dry weather and above average temperatures in the forecast this week. KEY MESSAGES: - High pressure provides a mostly clear night, with seasonable temperatures. KEY MESSAGES: - Above average temperatures and dry conditions continue under high pressure. Confidence is high that above average temperatures will continue into Wednesday as the ridge axis advances over the Great Lakes.
Splayed along its southern periphery is an elongated troughing associated with an old frontal boundary and best shows up at 700 mb. Expect continued warm and humid conditions with overnight lows falling in the lower to mid 80s and dew points holding in the upper 70s. A fairly weak pressure field across Keys waters this evening are being slightly controlled by a high over the eastern United States and day time heating over Florida contributing to weak troughing.
724 PM EDT Tue Sep 10 2024 High pressure across the northeast, and a blocked pattern aloft over the central United States will persist through the rest of the week. For Wednesday, weak warm advection in the low levels begins, allowing high temperatures to climb into the upper-70s, perhaps touching 80 in the Wyoming Valley.
1030 PM EDT Tue Sep 10 2024 High pressure continues to bring dry conditions to eastern New York and western New England through this weekend.
1004 PM EDT Tue Sep 10 2024 Low pressure exits the area tonight, with high pressure building into the area on Wednesday.
H5 ridging will be maintained across the eastern United States. Tropical low pressure will begin to move north in the vicinity of the lower Mississippi Valley tonight and Thursday.
Low temperatures by morning will be in the lower 60s to lower 70s across the region. Highs today will range from near 90 to the middle 90s with the warmer temperatures near the Rio Grande. Dry weather and warmer temperatures can be expected tomorrow. Highs will top out in the lower to upper 90s or about 2-3 degrees above normal for this time of the year.
PETSS guidance suggest the high tide again tonight will be of similar height to this morning where we are seeing elevated water levels (2.
Moisture surge from the system evident on both satellite and with the surface observations as dew points have surged into the lower to mid 60s as far north as central Arkansas. High temperatures on Wednesday will be rather warm over the majority of the state but cooler over the south as cloud cover steadily increases.
Otherwise, the short wave moves through later today, and upper ridging builds back over the area ahead of a digging trough over the Pacific NW.
120 AM EDT Wed Sep 11 2024 High pressure will continue to bring dry conditions to eastern New York and western New England today through the upcoming weekend. High pressure, currently directly overhead, will maintain clear/mostly clear and dry weather overnight with some patchy fog developing in some of the valleys.
Several hazards continue to linger along the Lower Texas Coast today into tonight as Hurricane Francine continues to move farther away from the region. Highs on Thursday will be a few degrees warmer than today, with widespread 90s to a few triple digits across the area. Lows tonight will fall into the low to mid 70s.
329 AM EDT Wed Sep 11 2024 High pressure sustains dry weather through Thursday, then the remnants of Hurricane Francine could potentially bring some rain late week into the weekend. High pressure retains control over the Central Appalachians and Middle Ohio Valley, allowing dry weather to continue throughout the near term forecast period. Temperatures will climb above normal today, reaching mid to upper 80s in the lowlands and upper 60s to low 80s in the mountains.
246 AM EDT Wed Sep 11 2024 Dry weather and above average temperatures will continue through the weekend with high pressure and ridging aloft. Dry conditions and plentiful sunshine under high pressure will allow another quick warm-up after sunrise. Afternoon highs will push into the 80s for most of the area outside the highest terrain. Overnight temperatures will fall back into the 50s, roughly five degrees warmer than Wednesday morning. KEY MESSAGES: - Above average temperatures and dry conditions continue under high pressure.
(Today through Thursday night) Dry weather persists across the Panhandles today as model agreement continues to see the upper-level trough build off the Rockies and move east over our area. Meanwhile to our far northwest, a upper-level trough does look to build in and progress eastward along the Canadian border late today into Thursday. Unfortunately, activity from the this trough is looking likely as the lasted runs continue to see the present ridge win out, which will leave us dry yet again Thursday.
Meanwhile an upper trough will dig into the Pacific Northwest. Weak lee troughing over the Rockies this afternoon will give way to warm southerly surface winds and near normal highs similar to yesterday in the upper 80s to lower 90s. Tonight, temperatures may be a bit warmer than the previous few nights with some low level moisture advection into the Rolling Plains from the hurricane. Low clouds may also move in or develop during the overnight hours across the aforementioned area, which may help to keep temperatures slightly warmer than previous nights in the lower 60s.
Its going to be a quiet night with this smoke trapped under this high pressure system. UPDATE Patchy fog was added to our west central MN counties towards north central MN to account for developing ground fog and a signal for patchy dense fog this morning where winds should remain much lighter (est of the front/trough axis). UPDATE Smoke continues to impacts eastern ND and is spreading east into northwest as the cold front continues south, and with the diurnal inversion forming it it seems to be getting trapped near the surface (particularly in the Red River Valley).
At the upper levels, water vapor imagery depicts troughing off the coast of the Pacific Northwest, and Hurricane Francine can be seen approaching the Louisiana coast. Not much change is anticipated for Thursday either, except for slightly warmer morning lows around 60 with just enough southerly wind overnight tonight to keep temperatures from dropping as much.
High pressure remains in control and continues to suppress moisture and cloud cover. Mid level thermal ridging will develop across E NM and far W TX Thursday.
An upper level low currently centered across our eastern counties will drift east today. Highs today will be in the upper 80s, with overnight lows in the low to mid 60s.
420 AM EDT Wed Sep 11 2024 High pressure will remain in control of our weather through the next several days, bringing above normal temperatures and plenty of sunshine. More of the same can be expected for Thursday, with temperatures a few degrees warmer.
A strong ridge of high pressure will remain over the region through the end of the week. The exception will be Thursday night, when increasing cloud cover related to Tropical Storm Francine will keep temperatures slightly warmer and in the low 60s.
With strong 850 hPa thermal ridging remaining over the Northern Plains and no precip expected, highs should warm for Wednesday and Thursday.
330 AM EDT Wed Sep 11 2024 High pressure centered over West Virginia will move to New England and remain nearly stationary into the weekend. Low pressure from a tropical system will move into the mid Mississippi Valley by the weekend and weaken. High pressure centered over the the Mid-Atlantic region will remain in control of our weather pattern. Today's afternoon temperatures will rise into the low 80s over NWPA/NEOH and mid to upper 80s are expected over NWOH. Temperatures will be a degree or two warmer on Thursday in the mid 80s for NWPA/NEOH and upper 80s to near 90 for NWOH.
1200 AM EDT Wed Sep 11 2024 High pressure and ridging aloft will keep dry weather and above average temperatures in the forecast this week. KEY MESSAGES: - High pressure provides a mostly clear night, with seasonable temperatures. KEY MESSAGES: - Above average temperatures and dry conditions continue under high pressure. Confidence is high that above average temperatures will continue into Wednesday as the ridge axis advances over the Great Lakes.
133 AM EDT Wed Sep 11 2024 High pressure will remain in control of our weather through the next several days, supplying plentiful sunshine and mainly warm weather. Coverage of fog in the typical river valleys is fairly uncertain as we have had a very dry day with dew points in the upper 30s to mid 40s in most places and some modest gradient flow will linger winds, especially in northern portions of Vermont further from the center of the high pressure area.
1004 PM PDT Tue Sep 10 2024 A low pressure pattern will usher in a significant change in the weather, leading to chances for showers and much cooler temperatures Wednesday and Thursday. Today through Thursday: Low pressure off the Pacific NW coast will move inland and across the region over the next 48 hrs. Showers will initially increase across the Cascades and far southeastern WA into the lower Idaho Panhandle later tonight.
Patchy fog was added to our west central MN counties towards north central MN to account for developing ground fog and a signal for patchy dense fog this morning where winds should remain much lighter (est of the front/trough axis). UPDATE Smoke continues to impacts eastern ND and is spreading east into northwest as the cold front continues south, and with the diurnal inversion forming it it seems to be getting trapped near the surface (particularly in the Red River Valley).

Early morning water vapor satellite imagery and RAP analysis reveal the amplification of the synoptic pattern is underway as a strong mid-level trough pushes ashore above the Pacific Northwest. As this feature progresses farther east daytime Wednesday, the surface lee trough in eastern CO/WY/MT will deepen, resulting in yet another day of breezy south to south- southeast winds across the central plains. Conversely, decreasing 500-mb heights will yield a marginally cooler afternoon as most areas hold in the upper 80s while locations along/near the OK and CO borders see highs in the low 90s once again. In response, the lee trough will intensify, fostering a noticeable jump in south to south-southeast winds.
153 AM EDT Wed Sep 11 2024 High pressure will continue to bring dry conditions to eastern New York and western New England today through the upcoming weekend. High pressure, currently directly overhead, will maintain clear/mostly clear and dry weather overnight with some patchy fog developing in some of the valleys.
Upper level ridging building over PA should ensure fair weather with nearly cloudless skies through the end of the work week. At the surface, high pressure is progged to pass east of New England, with ridging extending westward over PA.
134 AM EDT Wed Sep 11 2024 Cool and dry weather is expected through mid week as Canadian high pressure builds in from the north.
Oppressive heat and humidity prevails along the Keys island chain, with temperatures in the lower to mid 80s and dewpoints in the upper 70s to near 80 producing heat indices in the mid 90s to near 100 degrees as of 4 AM. Surface analysis depicts weak high pressure over the western Atlantic, with a stationary front draped over central Florida and the northern Gulf, and Hurricane Francine over the western Gulf. Excessive heat and humidity will be the primary weather concern again today, with highs in the lower 90s and dewpoints in the upper 70s to near 80 producing max heat indices around 110F this afternoon.
227 AM EDT Wed Sep 11 2024 High pressure sustains dry weather through Thursday, then the remnants of Hurricane Francine could potentially bring some rain late week into the weekend. High pressure retains control over the Central Appalachians and Middle Ohio Valley, allowing dry weather to continue throughout the near term forecast period. Temperatures will climb above normal today, reaching mid to upper 80s in the lowlands and upper 60s to low 80s in the mountains.
Small deviations in the track of the low will have large impacts on rainfall accumulations, but current indications are that the amount of rainfall will be beneficial to the area and not high enough to cause flooding. A sprawling ridge of high pressure extending from the Mid-Atlantic region through the Ohio and Mid-Mississippi Valleys into the southeast Plains will keep dry air locked in over our area at least through Wednesday night. Strong insolation is modifying the airmass today, producing temperatures around 5 degrees warmer than yesterday. Warmer temperatures today will naturally lead to warmer overnight lows tonight, and then warmer highs again tomorrow. Francine is forecast to move up the Lower Mississippi Valley on Thursday which will bring our area lowering and thickening ceilings and easterly winds.
Ridging aloft and dry air over the region will lead to a quiet weather day. Look for highs to climb into the low and mid 80s. The overall conundrum is how an upper level trough that digs in across the Intermountain West will interact with the Rex Block expected to set up over the Great Lakes region thanks to Hurricane Francine. Some ensembles favor the upper level trough weakening and being deflected north of the region.
As far as tonight goes, temperatures were running warmer than anticipated in the north and with the anticipated cloud cover and east wind through the night, morning lows may bottom out a couple degrees warmer.
High pressure centered over West Virginia will move to New England and remain nearly stationary into the weekend. Low pressure from a tropical system will move into the mid Mississippi Valley by the weekend and weaken. Quiet late summer weather is expected this period as high pressure from the surface to aloft remains in control over the area. A weak surface pressure gradient will allow a lake breeze to develop Wednesday which will keep the northern half of the lakeshore counties a bit cooler. Overnight lows will cool into the lower to mid 50s except near 60 along the lakeshore. Flow should be quiet with an upper level ridge in place over the NE CONUS and accompanying large high pressure at the surface.
130 AM EDT Wed Sep 11 2024 Dry high pressure will remain in place across the region through Wednesday. Tropical Cyclone Francine will track toward the Louisiana coast making landfall late Wednesday. The remnants are expected to drift north over the lower Mississippi River Valley through late week with a broad area of moisture moving north from the Gulf of Mexico to the Carolinas.
TONIGHT thru WEDNESDAY - Rain chances and smoke Stretch of nice late summer weather continues with pseudo zonal flow across the region and a few embedded short wave troughs to discern.
Upper 70s F to around 90 F expected by afternoon across the state with the lowest readings likely across the S/SW.
116 AM EDT Wed Sep 11 2024 High pressure across the northeast, and a blocked pattern aloft over the central United States will persist through the rest of the week. With clear skies to the east of the incoming high clouds, temperatures were slightly cooler than forecasted. Valley fog is beginning to develop and the high clouds will likely not have much of an effect of preventing the fog from spreading throughout the valleys this morning. For Wednesday, weak warm advection in the low levels begins, allowing high temperatures to climb into the upper-70s, perhaps touching 80 in the Wyoming Valley. High pressure at the surface will slowly settle east late in the week, with southerly flow leading to warming temperatures.
Today Currently early this morning, Hurricane Francine is southwest of the Louisiana Coast with high pressure and fairly weak flow locally in the lower-levels.
Trough over the Pacific NW Wednesday moves into Montana on Thursday, which will only enhance the south-southeast winds. 12z NAM deepens its lee cyclone down to 988 mb over eastern Wyoming 4 pm Thursday, and suspect S/SE winds Thursday afternoon/evening will be stronger than the strongest guidance.
Main rain chances of 60% or higher will be along and east of the highway 63 corridor in the eastern CWA. Southerly flow continues in the lower levels which will aid in temperatures rising into the mid to upper 80s. With the recent dry conditions that we've had across the area, there doesn't seem to be much of a flood risk at this time, with the higher QPF chances remaining to our east.
In the low-levels, the forecast area remains on the western periphery of high pressure centered across the eastern Great Lakes and upper Ohio Valley. A combination of a digging/amplifying upper trough over the Pacific Northwest, and the northward-moving tropical system (soon to be hurricane Francine) over the western Gulf of Mexico, is forecast to induce development of upper-level ridging across the Midwest and western Great Lakes region Wednesday into Thursday.
1128 PM EDT Tue Sep 10 2024 Low pressure exits the area tonight, with high pressure building into the area on Wednesday. High pressure remains to our south into Thursday night as the front stalls out near the Maine Quebec Border.
452 AM EDT Wed Sep 11 2024 High pressure will build in from the west today through Thursday.
412 AM EDT Wed Sep 11 2024 Cool and dry weather is expected through mid week as Canadian high pressure builds in from the north.
211 AM EDT Wed Sep 11 2024 High pressure sustains dry weather through Thursday, then the remnants of Hurricane Francine could potentially bring some rain late week into the weekend. High pressure retains control over the Central Appalachians and Middle Ohio Valley, allowing dry weather to continue throughout the near term forecast period. Temperatures will climb above normal today, reaching mid to upper 80s in the lowlands and upper 60s to low 80s in the mountains. Beyond Thursday, models are still not in agreement with the track of post-tropical cyclone Francine.
1239 AM EDT Wed Sep 11 2024 High pressure across the northeast, and a blocked pattern aloft over the central United States will persist through the rest of the week. With clear skies to the east of the incoming high clouds, temperatures were slightly cooler than forecasted. Valley fog is beginning to develop and the high clouds will likely not have much of an effect of preventing the fog from spreading throughout the valleys this morning. For Wednesday, weak warm advection in the low levels begins, allowing high temperatures to climb into the upper-70s, perhaps touching 80 in the Wyoming Valley. High pressure at the surface will slowly settle east late in the week, with southerly flow leading to warming temperatures.
138 AM EDT Wed Sep 11 2024 High pressure will strengthen across the local region tonight into Wednesday.
