Much warmer this afternoon after a chilly start to the day. Lows in the low to mid 40s will be common around sunrise. This is several degrees warmer than yesterday thanks to increasing low-level thicknesses.
604 AM CDT Mon Sep 9 2024 (Today) After another chilly start to the day, temperatures are forecast to warm into the 80s area-wide under mostly sunny skies as high pressure prevails.
752 AM EDT Mon Sep 9 2024 A weak trough will be nearby today into tonight. High pressure will otherwise be in control through the weekend.
700 AM EDT Mon Sep 9 2024 (Today through Tuesday) A frontal boundary emanating from an area of low pressure over eastern Canada continues to linger over northern Florida and the northern Gulf of Mexico while a weak ridge of Atlantic high pressure remains over southern Florida.
High pressure remain across the Ohio Valley today and tonight. A weak low pressure system associated with an upper trough across New England moves by to our north today and tonight. Except for some clouds associated with the low across NY state, skies will generally be mostly sunny today across the area.

1039 AM EDT Mon Sep 9 2024 A weak trough will be nearby today into tonight. High pressure will otherwise be in control through the weekend.
631 AM CDT Mon Sep 9 2024 (Today through Tuesday night) An anemic H500 flow across the southern CONUS due to a low amplitude broad ridge slowly advecting into the central Plains by this afternoon will keep the Panhandles dry throughout the short term forecast period. Similar pattern set up for tomorrow, with high temperatures a few degrees warmer than today in many locations.
634 AM CDT Mon Sep 9 2024 - Dry and warmer weather expected through much of the week.
A stationary frontal boundary remains stretched across northern Florida while high pressure ridges across southern Florida. The tropics are becoming active with Potential Tropical Cyclone Six located in the southwest Gulf of Mexico.
539 AM CDT Mon Sep 9 2024 (Today) Tranquil weather across the Tennessee Valley early this morning as we remain under the influence of an area of high pressure to our north. A cool/dry morning with temperatures in the upper 50s will give way to a fairly warm day as the ridge amplifies over the Ohio and Tennessee Valleys. Despite the higher temperatures, RH values will drop into the 35-40 percent range -- making for a more comfortable feel despite the higher temperatures.
Cooler and wetter conditions will return to western Washington this week as a series of systems cross the region.
643 AM EDT Mon Sep 9 2024 - High swim risk part of nw lower MI this morning - Warming and drying trend through much of the week - Chances for rain over eastern upper mid week Pattern/synopsis: Weak (1011mb) low pressure is over eastern Superior. Surface ridging extends from the OH Valley to IA and MN. A trof axis/weak cold front settles south across the area this morning (north of M-68) thru early/mid-afternoon, somewhat enhancing stratocu coverage in the vicinity.
728 AM EDT Mon Sep 9 2024 - Dry weather and warmer temperatures on the way - Low confidence in tropical moisture arriving end of the week - Dry weather and warmer temperatures on the way One last short wave on the far western periphery of the upper low is dropping through the thumb region early this morning. High pressure only continuing to move in will keep cloud cover limited, and maybe even clear with little to no low level moisture floating by.
648 AM EDT Mon Sep 9 2024 Cool and dry high pressure will remain in place across the region through the middle of the week with moderating temperatures. A tropical system lifting north from the western Gulf of Mexico into the Lower Mississippi River Valley will bring an increase in moisture and showers to the area late week. Weak high pressure has already moved into place over the central Appalachians early this morning, and there it shall park itself for the next 24 hours, keeping us mostly sunny/clear. The axis of a mid/upper trof will move off to our east today keeping the western Carolinas in a weakening NW flow aloft.
As the trough moves through, slight chances (mainly 15%) for showers will transit the state during the late evening and overnight hours. On Tuesday, a cold front will sweep through the state from northwest to southeast, helping push the surface smoke out of the area. Highs on Tuesday will mainly be in the 80s, with some locations in the south reaching into the lower 90s. Meanwhile, a very potent trough is forecast to develop across the Pacific Northwest through the middle of the week, bringing about the next active period of weather for the Northern Plains.
940 AM CDT Mon Sep 9 2024 - Temperatures climb the next several days, turning much warmer by the middle of the week.
Issued 1007 AM CDT Mon Sep 9 2024 Calm and quiet conditions continue across southern Wisconsin beneath high pressure. Patterson Issued 415 AM CDT Mon Sep 9 2024 Today through Tuesday: Quiet conditions continue today beneath high pressure. Warm advection and warm 925 to 850mb temperatures should allow our daytime highs to reach the low 80s over most of southern WI. Tuesday's highs will be a few degrees warmer and skies will be features some scattered mid level clouds as a thermal ridge at 850mb and 700mb moves over the Upper Mississippi Valley. CAMs show showers over west central WI with this thermal ridge, but we'll likely remain dry as the ridge will lose its strength as it leans into southeast WI late in the day and dry air will be present from the surface to 700mb.
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.
1222 PM EDT Mon Sep 9 2024 A trough of low pressure will remain over Eastern Canada today.
There were even a couple readings in the low 40s in the east.
Afternoon high temps will be in the low 90s, and while this isn't far from climatological norms, the dewpoints in the mid to upper 70s will result in heat indices of 103-108, especially over the far southern portion of the peninsula. High temps on Tuesday will again be in the lower 90s.
318 PM EDT Mon Sep 9 2024 * An isolated shower or thunderstorm possible across the northern tier of central PA this afternoon and evening * Extended stretch of rain-free weather Tuesday into the weekend with temperatures trending warmer/above normal * No impacts are expected at this time from Tropical Storm Francine An isolated shower/tstm remains possible through this evening mainly along and north of I80 with max POPs over the northern tier (near and north of US6 to NY border). 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.
A weak cold front will drop through the region this afternoon which will veer the winds from the current southwest to northwest this evening. Cold advection behind the front will help sharpen a low level inversion with moisture advection off Lake Huron helping to saturate the low levels. Short wave impulses rotating across Lake Huron this morning and will drive a weak sfc cold front into Se Mi this afternoon. The earlier passage of the trough axis across the thumb will veer winds toward the north late in the day, leading to a subtle late day cooling trend in this area.
140 PM EDT Mon Sep 9 2024 High pressure and a dry airmass will remain in place across the region through mid week. Conditions will be nearly ideal for radiational cooling tonight as the lower atmosphere decouples and winds become calm.
Big Change to Wetter, Cooler with High Elevation Snow Later.
-Dry weather looks to continue with tropical moisture staying east and troughing staying west of the area. Temperatures are a touch warmer than yesterday, in the mid 80s at 19Z. Without a significant pattern change, these slightly warmer than average afternoon temperatures can be expected each day this week, with morning lows staying around 60 degrees. Meanwhile, a large mid-level closed low pressure system will pivot over the Pacific Northwest and lift northeast into southern Canada late in the week. The approaching trough axis will induce lee cyclogenesis and few associated showers/storms across the High Plains of Nebraska/KS.
217 PM EDT Mon Sep 9 2024 High pressure lasts through much of this week. High pressure continues to strengthen over the region, keeping the near term quiet with clear skies. Temps tonight will drop rapidly once again with prime radiational cooling conditions, reaching 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.
Much warmer this afternoon after a chilly start to the day. 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).

A trof axis/weak cold front settles south across the area this morning (north of M-68) thru early/mid-afternoon, somewhat enhancing stratocu coverage in the vicinity.
1147 AM CDT Mon Sep 9 2024 (Rest of Today) Current temps are gradually climbing into the lower/mid 60s this Mon morning, from their earlier lows mainly in the mid 50s/near 60F. This cloud cover should diminish over the next few hrs, as high pressure settles more into the OH Valley states, while weak upper ridging builds eastward into much of the region. With the oncoming ridge pattern, afternoon highs will climb more into the mid/upper 80s, which is a few degrees higher compared to the last couple of days.
1207 PM CDT Mon Sep 9 2024 (The rest of today) Temperatures will warm into the 80s areawide this afternoon underneath mostly sunny skies and light southerly winds as high pressure dominates the region.
358 PM EDT Mon Sep 9 2024 A weak cold front approaches tonight. High pressure will otherwise be in control through the weekend. Tonight, the 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.
- Dry and warmer weather expected through much of the week.
228 PM EDT Mon Sep 9 2024 High pressure will be over the area this week keeping the weather dry. High pressure will maintain control of the weather pattern through Tuesday, resulting in clear skies and light & variable winds. There will be a few spots in the more sheltered mountain valleys where temperatures fall into the low to mid 30s, and may see a few pockets of frost develop. Sunny skies are expected for Tuesday, and a few degrees warmer with highs ranging from the mid 70s to the low 80s.
231 PM EDT Mon Sep 9 2024 A weak cold front approaches this afternoon into tonight. High pressure will otherwise be in control through the weekend.

1045 AM PDT Mon Sep 9 2024 Noticeably cooler temperatures will settle over the region starting late Tuesday, as a larger low pressure system descends on the Pacific northwest.
main concern will be a fairly potent trough moving in late in the week. Looking at the end of the forecast period, ensemble guidance products want to bring a more potent trough to the region which will have a better threat of bringing some moisture (and a cooling trend) to the region. Weak convection over the higher terrain this afternoon will likely generate outflows 22z-02z, with potentially a brief period of gusty/erratic winds at KALS and KCOS.
High pressure remains the dominant synoptic feature across the Florida Keys, but it has weakened since yesterday and winds are a few knots lower today. High pressure over the western North Atlantic extending westward into South Florida will maintain gentle to occasionally moderate east to southeast breezes across the Keys coastal waters through midweek. Tropical Storm Francine moving inland from the northwestern Gulf Coast into the Lower Mississippi Valley will weaken the Atlantic ridge, resulting in light to gentle east to southeast breezes over the Keys waters late this week.
Lastly, with lingering warm air advection aloft (WAA) and southerly surface winds still in play; expect our temperatures to stay a bit elevated overnight with lows only dropping into the low to mid 60s.
Discussion: High pressure at the surface and aloft will provide a dry period for the short term. Tomorrow will feature plenty of sunshine, and despite the cooler start high temperatures in the afternoon will be slightly above seasonal normals.
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.
10 AM temperatures are in the upper 60s to low 70s under clear skies as high pressure centered over Kentucky continues to dominate our weather pattern. Afternoon highs should be a bit warmer than yesterday ranging from the low 80s in the north, to upper 80s or even near 90 degrees south of Tupelo.
