High pressure will remain in control through the weekend and it will bring plentiful sunshine. Otherwise, the forecast remains on track with this round of precipitation largely the last chances of rain before strong high pressure builds over the region. High pressure will build into the region tomorrow and bring a classic early fall day, with highs in the 60s and low 70s, and mostly sunny skies. Fantastic early fall weather will continue into the latter half of the week as ridging keeps hold across the region.
653 PM CDT Mon Sep 9 2024 Quiet conditions continue tonight with slightly warmer temperatures than last night, in the upper 60s and low 70s. Moistening trend continues tomorrow, as upper ridging begins to build to the southeast, amplified by a strengthening tropical storm Francine. The increased rain and clouds will also limit high temperatures for the southern half tomorrow, in the 80s, while the northern half will peak in the low 90s.
512 PM EDT Mon Sep 9 2024 - One more night of near-record low temperatures, then warmer through mid-week.
550 PM MDT Mon Sep 9 2024 - Afternoon showers and thunderstorms will continue to be favored over the higher terrain the next few afternoons.
A deep low pressure trough is arriving off the coast on Tuesday with rain arriving at the coast late Tuesday night.
Isolated convection is expected across the higher terrain of the Mojave Preserve, Clark, Lincoln, and Mohave counties this afternoon.
There is the low chance for showers overnight tonight but forcing is very weak so the probability is very low thanks to lower level dry air. The wave is accompanied by steady 850mb warm advection, but no low level jet, minimal 0-6km effective shear, and very dry air in the low layers. Have not really noticed it being too thick during the days, definitely not enough to result in cooler highs.
1056 PM EDT Mon Sep 9 2024 High pressure and a large ridge building into the region starting tonight will bring fair, dry weather through at least the rest of the week. High pressure and increased ridging will start to build east toward the region. High temperatures will be in the upper 60s to mid 70s from the higher terrain to the lower elevations respectively.
501 PM EDT Mon Sep 9 2024 - One more night of near-record low temperatures, then warmer through mid-week.
Expect drier and gradually cooler weather throughout the week.
722 PM CDT Mon Sep 9 2024 (This afternoon through Tuesday) The post-frontal airmass remains in place across Central Alabama with easterly surface flow and a large region of high pressure centered over the Midwest. Temperature profiles will begin warming slightly today as heights rise behind the departing mid-level trough over the Northeastern CONUS. Comfortable tonight with lows in the lower 60s north to upper 60s south.
934 PM EDT Mon Sep 9 2024 - One more night of near-record low temperatures, then warmer through mid-week.
739 PM EDT Mon Sep 9 2024 High pressure and a dry airmass will remain in place across the region through mid week. Lows tonight will be in the mid 40s to lower 50s, although some outlying areas may even get a bit cooler. The airmass will continue to moderate with highs on Tuesday in the the low to mid 80s. Lows Tuesday night will be mostly in the low to mid 50s.
605 PM CDT Mon Sep 9 2024 (This evening through Tuesday) Upper level high pressure remains overhead late this afternoon, although a weak low located south of El Paso will move northeastward moving over much of the forecast area by end of day Tuesday, but a dry, deep air mass over the region no effects to sensible weather are noted.
WPC Clusters are in good agreement showing a trough moving through the northwest CONUS late this week. This area bears watching over the next few days as low pressure evolves and moves into the area.
1048 PM EDT Mon Sep 9 2024 A weak cold front approaches tonight, and across early Tuesday. High pressure will otherwise be in control through next Monday. Tonight, a cold front continues to approach the area. Ahead of the cold front and with some positive vorticity advection with an upper level trough axis moving through, a few showers will be possible. The lows for tonight used the bias corrected MOS consensus, which leaned more towards warmer side of MOS for interior areas. The range of lows forecast is from the lower 50s to lower 60s. The mid levels show a consistent ridging trend. The trough exits east of the region Tuesday.
A cooling trend will occur across Central California as an upper level high pressure system begins to weaken over the next few days. An upper level trough is projected to drop southward into the western United States midweek, bringing about near normal temperatures to Central California.
Recent radar/lightning data shows isolated showers/a few storms from around Pine Ridge to the northern Nebraska sandhills.
A lower tropospheric Atlantic ridge reaches westward across our area into the eastern Gulf of Mexico. In addition, while not completely disappearing, the lower level inhibition should weaken and the lower level flow, while remaining weak, may become better organized. The Keys reside in weak pressure field between a high over the eastern United States and the Atlantic ridge off to our northeast.
As of 8pm, there remain a few light showers over southeast MT, at tail of trof axis sliding into the Dakotas. Tuesday will be cooler but still w/ above normal temps. WPC Clusters are in good agreement showing a trough moving through the northwest CONUS late this week. This area bears watching over the next few days as low pressure evolves and moves into the area.
1013 PM EDT Mon Sep 9 2024 - Warming trend through much of the week - Chances for showers over eastern upper Tuesday night Large area of strong high pressure remains centered from James Bay thru Michigan into the Mid Mississippi and Ohio Valleys late this evening. High pressure slips off to our east Tuesday. Sunshine will become mixed with mid-high level clouds with a warmer return southwest flow developing. Pattern Forecast: Broad ridging expected to encompass much of the eastern two thirds of the CONUS by the start of the period Tuesday night.
Another extended stretch of rain- free weather is expected from Tuesday into the weekend with temperatures trending warmer. High pressure will dominate the sensible wx pattern through midweek. High pressure will remain firmly in place over the Mid-Atlantic and New England regions late this week.
Much warmer this afternoon after a chilly start to the day. Looking for a clear and quiet night across the area with high pressure in control. RAP 500 MB analysis and water vapor imagery showed a trough over the northeast portion of the CONUS with a ridge of high pressure building across the southwest. The trough of low pressure that brought cooler than average temperatures will continue to move to the east as the high pressure builds across the desert southwest. Before heat associated with the ridge returns, low temperatures tonight will be mainly in the mid to upper 50s (between 5 and 10 degrees below normal).
736 PM EDT Mon Sep 9 2024 Cool and dry weather is expected for the first half of this week as Canadian high pressure builds in from the north.
Temperatures are generally in the lower to mid 70s. High pressure should remain in control as it anchors in across the spine of the Appalachians. There were even a couple readings in the low 40s in the east.
746 PM EDT Mon Sep 9 2024 A weak cold front approaches tonight, and across early Tuesday. High pressure will otherwise be in control through next Monday. Tonight, a cold front continues to approach the area. Ahead of the cold front and with some positive vorticity advection with an upper level trough axis moving through, a few showers will be possible. The lows for tonight used the bias corrected MOS consensus, which leaned more towards warmer side of MOS for interior areas. The range of lows forecast is from the lower 50s to lower 60s. The mid levels show a consistent ridging trend. The trough exits east of the region Tuesday.
High pressure will remain in control through the weekend and it will bring plentiful sunshine. These will continue for the next 3 hours before dissipating in the increasing stability behind the passing upper trough. High pressure will build into the region tomorrow and bring a classic early fall day, with highs in the 60s and low 70s, and mostly sunny skies. Fantastic early fall weather will continue into the latter half of the week as ridging keeps hold across the region.
651 PM CDT Mon Sep 9 2024 (This evening through Tuesday Night) Northeasterly surface winds will prevail tonight as surface ridging remains over the Ohio River Valley.
In the meantime its pretty quiet in the short term: Overnight conditions will bounce back to more seasonal norms tonight with our coldest temperatures ranging from the low 60Fs in the north to low 70Fs in the southeast. /OAJ/ Quiet conditions continue tonight with slightly warmer temperatures than last night, in the upper 60s and low 70s. Moistening trend continues tomorrow, as upper ridging begins to build to the southeast, amplified by a strengthening tropical storm Francine. The increased rain and clouds will also limit high temperatures for the southern half tomorrow, in the 80s, while the northern half will peak in the low 90s.
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. Quiet weather is going to dominate through the work week as the mid/upper level flow pattern features ridging over the next couple of days that will gradually transition towards west to southwest flow ahead of broad troughing over the western CONUS.
Low temperatures will be similar to marginally warmer compared to last night, generally in the mid 40s to lower 50s for most areas.
1031 PM EDT Mon Sep 9 2024 High pressure lasts through much of this week. High pressure brings another quiet day with clear skies and highs in the low to mid 80s inland, upper 70s to near 80 for beaches. 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.
1020 PM EDT Mon Sep 9 2024 High pressure and a dry airmass will remain in place across the region through mid week. Lows tonight will be in the mid 40s to lower 50s, although some outlying areas may even get a bit cooler. The airmass will continue to moderate with highs on Tuesday in the the low to mid 80s. Lows Tuesday night will be mostly in the low to mid 50s.
713 PM EDT Mon Sep 9 2024 High pressure lasts through much of this week. High pressure remains overhead early this evening with setup looking ideal for radiational cooling. This trend will continue into the evening, bottoming out in the low 50s inland and low 60s (maybe even upper 50s) for beaches. High pressure brings another quiet day with clear skies and highs in the low to mid 80s inland, upper 70s to near 80 for beaches. 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.
(This evening through Tuesday Night) Northeasterly surface winds will prevail tonight as surface ridging remains over the Ohio River Valley.
Currently at the surface, a broad area of high pressure holds over the eastern US to the north of a stalled frontal boundary draped across northern Florida and the northern Gulf of Mexico, while Tropical Storm Francine lumbers over the western Gulf of Mexico.
1214 AM CDT Tue Sep 10 2024 (This evening through Tuesday Night) Northeasterly surface winds will prevail tonight as surface ridging remains over the Ohio River Valley.
Increased moisture and abundant cloud cover will allow Wednesday morning lows to be several degrees warmer than today. Extensive cloud cover will help keep temperatures cooler across southern parts of the state, while northern areas will likely approach 90 F by the afternoon.
Sunny skies and light southerly winds have allowed for a beautiful day with temperatures warming into the low to mid 80s this afternoon. A bit of uncertainty in this outcome does exist Tuesday morning as forecast models show a frontal boundary and weak upper-level trough passing through southern MN. The low chances for precip should move east of our area by Tuesday evening, resulting in the rest of the work week being dry.
One more day of well above normal temperatures before a cold frontal passage on Wednesday. As the trough moves onshore a cold front will move through bringing showers and scattered thunderstorms on Wednesday. Showers, gusty northwest winds, and much cooler air will overspread all zones Wednesday as the cold front moves through.
(Today and tonight) Early this morning, temperatures across west central Texas were in the upper 50s to low 60s with dewpoints around 50, indicating a dry, cooler-than-normal airmass in place. At the surface, high pressure that was centered over the Ohio Valley yesterday has lifted northeast and will have much less influence on the weather over west central Texas today. The forecast should be similar to yesterday with afternoon high temperatures in the low to mid 80s. Overnight lows should be a few degrees warmer than last night as higher dewpoints begin to creep northward into the region.
As the main low amplitude H500 builds into the Four Corners Region this afternoon, dry and warm conditions will spread downstream of the trough axis across the southern High Plains. Low temperatures tonight and tomorrow night will range from the lower to upper 50s.
1201 AM CDT Tue Sep 10 2024 (This evening through Tuesday) Upper level high pressure remains overhead late this afternoon, although a weak low located south of El Paso will move northeastward moving over much of the forecast area by end of day Tuesday, but a dry, deep air mass over the region no effects to sensible weather are noted.
Another extended stretch of rain- free weather is expected from Tuesday into the weekend with temperatures trending warmer.
341 AM EDT Tue Sep 10 2024 High pressure will move overhead today, before progressing offshore tomorrow. High pressure currently centered over the Appalachians will progress overhead today. Winds will be light out of the northwest, and high temperatures will generally be in the low to mid 80s for most, with 70s in the mountains. The combination of clear skies and calm winds will lead to ideal conditions for radiational cooling, allowing temperatures to drop back into the low to mid 50s (low 60s in downtown DC/Baltimore).
208 AM EDT Tue Sep 10 2024 High pressure sustains dry weather through much of the work week, with a gradual warming trend.
239 AM EDT Tue Sep 10 2024 High pressure will be over the area this week keeping the weather dry. Key Message: -High confidence in dry and slightly warmer weather. The Mid Atlantic region and much of the southern states had mostly clear skies under high pressure, with patchy fog noted in river and mountain valleys early this morning. It will also keep low temperatures a few degrees warmer than this morning, with readings in the 40s and 50s.
407 AM EDT Tue Sep 10 2024 Cool and dry weather is expected for the first half of this week as Canadian high pressure builds in from the north.
320 AM EDT Tue Sep 10 2024 - One more night of near-record low temperatures, then warmer through mid-week.
222 AM EDT Tue Sep 10 2024 High pressure sustains dry weather through much of the work week, with a gradual warming trend.
Increasing upper level ridging will dominate through the upcoming week with the main northern stream energy remains well west of the region into this weekend. At the surface, high pressure centered over the Ohio River will slowly move east, reaching the eastern US by Wednesday. While low level thermal fields will increase, allowing a return to above normal temperatures in the 80s and maybe a few 90s mid week, moisture return will be much slower, advecting in either from the west on the edge of the high pressure or potentially with the arrival of tropical moisture this weekend.
(This evening through Tuesday) Relatively tranquil conditions will continue today and tomorrow with surface ridging and a dry airmass in place. Really about the only weather feature of note this period will be fire weather conditions pushing up into elevated territory tomorrow afternoon as lee troughing deepens east of the Rockies and winds increase slightly over today's values.
309 AM EDT Tue Sep 10 2024 Another extended stretch of rain-free weather is expected to last into the weekend with temperatures trending warmer. Ridge tops will stay 5-6F cooler. High pressure will dominate and control the sensible wx pattern through midweek. Temperatures will get 5-6F warmer on Wed (9/11) vs Tues in the N, and 2-3F warmer in the S. High pressure will remain firmly in place over the Mid-Atlantic and New England regions late this week.
Surface pressure gradient is expected to weaken tonight under a ridge extending north from the Ohio valley high. - Warming Trend Continues Tomorrow A broad upper-level ridge moves over the region on Tuesday with jet streaks moving far away. High pressure centered over the mid- Atlantic states will turn our low-level flow more from the southwest, advecting warmer air our way.
347 AM EDT Tue Sep 10 2024 High pressure sustains dry weather through much of the work week, with a gradual warming trend.
1053 PM MDT Mon Sep 9 2024 - Afternoon showers and thunderstorms will continue to be favored over the higher terrain the next few afternoons.
317 AM EDT Tue Sep 10 2024 - Mainly dry with increasingly warmer temperatures - Low confidence in tropical moisture arriving end of the week - Mainly dry with increasingly warmer temperatures We have maintained a dry forecast through Wednesday (and beyond). High pressure is directly overhead this morning. This is the time of the year for better fog potential, especially under light winds, with a cooler air mass, longer nights, and a relatively warm ground. Once the short wave moves by before Wednesday morning, we will see the upper ridge build a bit again just west of the area. - Low confidence in tropical moisture arriving end of the week Model agreement is good on flat upper ridging prevailing this week.
The upper ridge that has been parked over the Four Corners will begin to flatten and move eastward today and tonight. The only consequence to the FA will be slightly warmer temps today on the order of two to three degrees over yesterday. Surface lee troughing will keep surface winds out of the south to southeast once again with sustained winds averaging 15 mph or less with the higher end being most prevalent across our northwestern zones.
313 AM EDT Tue Sep 10 2024 High pressure and a dry airmass will remain in place across the region through mid week. Temperatures will be warmer again today based on increasing mid-level heights. Dry air in the low levels (and a very dry ground) will allow temperatures to fall below normal tonight, then rise above normal on Wednesday. As we head towards the end of the work week, our focus begins to shift to the remains of Francine which is expected to transition over to an upper level closed low.
Dew points will remain low and we still have a couple more dry days in the forecast, but temperatures will climb back above normal today and tomorrow as some weak ridging builds into the region. Highs in the low 90s and with the dew points in the 50s, it shouldn't be uncomfortable, by any stretch.
High pressure will remain in control through the weekend and it will bring plentiful sunshine. These will be dissipating in the increasing stability behind the passing upper trough. High pressure will build into the region tomorrow and bring a classic early fall day, with highs in the 60s and low 70s, and mostly sunny skies.
Looking for a clear and quiet night across the area with high pressure in control. RAP 500 MB analysis and water vapor imagery showed a trough over the northeast portion of the CONUS with a ridge of high pressure building across the southwest. The trough of low pressure that brought cooler than average temperatures will continue to move to the east as the high pressure builds across the desert southwest. Before heat associated with the ridge returns, low temperatures tonight will be mainly in the mid to upper 50s (between 5 and 10 degrees below normal). Warm and dry weather continues through Wednesday night as a blocking upper ridge remains parked over the Great Lakes.
- There are strengthening signals that remnants of a tropical system over the Western Gulf will bring beneficial rain to the area late this week with the highest potential over southeast Missouri into southwest Illinois. Despite that a strong warm air advection feature doesn't quite jump out at us tonight into Tuesday, mid-level ridging shifts east far enough for return flow to draw warmer temperatures into the region.
Clear and sunny again today with ridging across the region. Dry air remains in place with warmer temperatures.
Southerly winds will continue to bring warmer air into the area.
Midlevel heights are forecast to increase slightly today and should yield temperatures a degree or 2 warmer than yesterday with highs in the mid 80s to lower 90s.
1145 PM EDT Mon Sep 9 2024 - Warming trend through much of the week - Chances for showers over eastern upper Tuesday night Large area of strong high pressure remains centered from James Bay thru Michigan into the Mid Mississippi and Ohio Valleys late this evening. High pressure slips off to our east Tuesday. Sunshine will become mixed with mid-high level clouds with a warmer return southwest flow developing. Pattern Forecast: Broad ridging expected to encompass much of the eastern two thirds of the CONUS by the start of the period Tuesday night.
232 AM EDT Tue Sep 10 2024 High pressure and ridging aloft will keep dry weather and above average temperatures in the forecast this week.
134 AM EDT Tue Sep 10 2024 High pressure and a dry airmass will remain in place across the region through mid week. Lows tonight will be in the mid 40s to lower 50s, although some outlying areas may even get a bit cooler. The airmass will continue to moderate with highs on Tuesday in the the low to mid 80s. Lows Tuesday night will be mostly in the low to mid 50s.
The low level dry air will attribute to efficient boundary-layer mixing Tuesday afternoon, making for breezy conditions and gusts up to 30mph in the north. Upper level ridging will build in behind the departing wave and boost temperatures further into the 80s. H250 winds (30,000ft in the air where the smoke is located) are minimized Wednesday as the ridge axis centers overhead. The forecast becomes more uncertain over the second half of the week for two reasons: Francine and the Pacific trough.
313 AM EDT Tue Sep 10 2024 High pressure will remain in control through the week. An upper level ridge will remain nearly stationary over the Ohio Valley and Great Lakes region today through Wednesday which will keep the weather quiet. At the surface, a high pressure system will remain over the Ohio Valley and Northeast CONUS through Wednesday. Afternoon temperatures will range from the upper 70s over NWPA to the low and mid 80s over northern Ohio. Temperatures will be warmer on Wednesday in the lower 80s over NWPA and middle 80s over NEOH. It will be even warmer in the upper 80s across NWOH.
139 AM EDT Tue Sep 10 2024 Cool and dry weather is expected for the first half of this week as Canadian high pressure builds in from the north.
1010 PM MDT Mon Apr 21 2025 - Breezy winds today will continue into Monday evening with peak gusts around 30-45 mph - A Wind Advisory is in effect Monday for the Snake River Plain, Eastern Magic Valley, and Raft River Region until 9PM MDT Afternoon satellite imagery shows an upper trough continuing to move east of the area but the tight pressure gradient remains in place nevertheless, leading to a windy day across much of eastern Idaho. Overnight temps will run around seasonal norms for late April with 20s generally across the high country and 30s in the valleys.
