Cooler temperatures return later in the week with a chance for lower elevation rain and mountain snow by the weekend. Gusty west to northwesterly winds over the plains will also continue to diminish tonight as the responsible low pressure system moves away from the forecast area.
Breezy conditions are expected much of the week along with a gradual cooling trend as two low pressure systems move through the region.
109 AM EDT Tue Apr 23 2024 Showers will develop Tuesday into Tuesday night as a cold front moves through region. A mid level short wave will drop down across the upper Ohio Valley Tuesday into Tuesday night, with an associated cold front moving through our area Tuesday night. Wednesday night, favorable radiative cooling conditions will allow low temps to plummet back into the 30s, with perhaps some locations dipping below the freezing mark. A warming trend will ensue through the remainder of the work week and into the weekend as H5 ridging builds in across the eastern CONUS.
217 AM EDT Tue Apr 23 2024 High pressure will remain in control of the region through today with a weak front coming through Wednesday which could provide a slight chance of light showers.
The warming trend will continue on Wednesday, despite the passage of a weak cold front tonight.
(Today) Warming trend continues today ahead of cold front, which is forecast to move into northeast Oklahoma by mid afternoon.
438 AM EDT Tue Apr 23 2024 -Frost this morning; then breezy & warmer with low humidity -Periods of rain showers tonight through Wednesday afternoon -Rain-free late week with renewed frost/freeze risk Thu & Fri Another chilly start today with a frost advisory in effect until 8AM for active growing season counties from the eastern Alleghenies into the middle and lower Susquehanna Valley. Low temps tonight in the low 40s/50s are +10-15 degrees warmer than the last two nights (no frost) thanks to an active southwest to westerly breeze along with clouds/rain showers. Highs on Wednesday will trend cooler and range from the upper 40s in the northern tier to mid 60s in the southeast.
231 AM CDT Tue Apr 23 2024 - Cooler today with 15 to 30 mph sustained northerly winds this morning gradually easing off by late in the day.
525 AM CDT Tue Apr 23 2024 - Strong north to northeast winds will overspread southwest KS Tuesday morning and afternoon behind a cold front.
620 AM CDT Tue Apr 23 2024 - A weak cold front will bring a chance of showers and a few thunderstorms to the area late this afternoon through late tonight.
938 AM EDT Tue Apr 23 2024 Quiet day in store as high pressure builds into the region. Temperatures will be cooler today behind the front, topping out just a degree or two below average.
Issued by National Weather Service Pittsburgh PA 1036 AM EDT Tue Apr 23 2024 Dry and breezy today ahead of a cold front. Dry conditions will continue today before a cold front swings through overnight bringing generally light rain to the region. Breezy southwesterly winds this afternoon and into early evening can be expected ahead the mentioned front, however, most locations should see a relatively brief period of lighter winds this evening with decoupling prior to FROPA Afternoon min RH values in the lower 20s, low 10hr fuel moisture values, and gusts up to 25mph has prompted the issuance of a fire danger statement for today after coordination with land management agencies. Key Points: * Cold front exits east Wednesday morning.
643 AM CDT Tue Apr 23 2024 (Today through Wednesday) An upper ridge gradually builds/subsidence increases over the region during the period. Select NAM deterministic soundings suggest a lowering of CIN values during the afternoon hours today/Wednesday, yet the lack of sufficient lift, and the building upper ridge, will preclude convective development.
444 AM PDT Tue Apr 23 2024 Cooler, unsettled conditions return today and continue throughout late week with coastal drizzle possible this morning and again tonight into Wednesday morning.
(Tuesday through Wednesday) Quiet morning for us in the wake of exiting high pressure of 1024mb edging into Georgia now. Overnight air temps will start to see warmer readings with upper 50s and lower 60s as dew points continue upwards. The warmer start will edge highs into the lower 80s for many of our sites. A broad upper ridge over TX and the plains states will be slowly working our way with rising heights locking in the warmer trend through the rest of this week.
This dry air will continue to filter in as a broad area of high pressure along the Eastern Seaboard consolidates near the Carolina/Georgia region this afternoon.
Above average temperatures remain in place through mid-week as high pressure dominates. A closed low system will progress inland through the second half of the week, bringing cooler and wetter weather into the weekend.
850 AM EDT Tue Apr 23 2024 High pressure will shift southeast offshore today. A dry cold front will approach from the NW late tonight, then shift across the region Wednesday.
714 AM EDT Tue Apr 23 2024 Dry and seasonably warm weather is expected most of today as high pressure moves east of the area. Showers will return late today and tonight, and continue through part of Wednesday, with a crossing cold front. KEY MESSAGES: - Dry and warmer today - Wind gusts around 25 mph this afternoon ------------------------------------------------------------------ Made a morning update to adjust the temperatures and dew points to the current trends. Continued with the frost advisory through 9 AM, with several more sheltered locations reporting temperatures in the lower to mid 30s.

Overnight air temps will start to see warmer readings with upper 50s and lower 60s as dew points continue upwards. The warmer start will edge highs into the lower 80s for many of our sites. A broad upper ridge over TX and the plains states will be slowly working our way with rising heights locking in the warmer trend through the rest of this week.
635 AM EDT Tue Apr 23 2024 High pressure will move offshore and allow for a gradual warmup until a back door cold front arrives Wednesday night.
708 AM EDT Tue Apr 23 2024 (Today through Wednesday) A departing upper trough/front complex will drift northeastward, leaving breezy northeasterly winds in its wake. This will result in cooler/drier conditions compared to prior days, particularly along the Atlantic coast/metro region of South Florida. Expect maximum temperatures to reach the upper 70s to around 80 degrees along the east coast, while the interior and west coast may reach the low/mid 80s. Maximum temperatures again span from the low to mid 80s, with overnight lows ranging from the 60s to around 70 degrees.
Cooler, unsettled conditions return today and continue throughout late week with coastal drizzle possible this morning and again tonight into Wednesday morning.
(Today and tonight) High pressure dominates the region for today with warming temperatures into the upper 70s and low 80s with light surface winds becoming southerly by this afternoon and evening; and zonal flow aloft. Overnight temperatures will be in the low 50s.
(Today through Wednesday) Forecast over the next few days and generally even into the weekend is quiet with the only real noticeable change being warmer temps and slowly increasing moisture. Once the s/w over the Great Lakes moves into the northeastern states tomorrow we will see a stout ridge begin to build over the Plains and Continental Divide. That along with high pressure at the sfc pushing farther east will lead to southeasterly and southerly LL flow returning.
Flat zonal winds at the mid/upper levels are progged to become more northwest- erly through tomorrow as the next longwave trough approaches/begins to develop over the southern US west coast. This along with a deep- ening onshore flow at the lower levels here should result in warmer temperatures the next couple of days (and beyond). But, not at all confident with this scenario at this time given the building ridge aloft.
559 AM CDT Tue Apr 23 2024 (Today) Relatively tranquil conditions across the Tennessee Valley early this morning with high pressure still in control of the sensible weather. The end result will be a mostly sunny and warmer day as southwest flow serves to advect in a warmer air mass -- with highs returning to the low to mid 70s.

Sfc ridging has begun to shift east of the area this morning and will continue to make progress throughout the day. Clouds will increase and a cold front will approach from the NW later today. Highs on Wednesday are expected to be a few degrees cooler across much of the state compared to today.
A cold front associated with the system to our north may dip into far northern parts of our forecast area late tonight, but warming ahead of this front will actually result in warmer temps across the board compared with this morning's temps.
629 AM CDT Tue Apr 23 2024 (Today through Wednesday) Mid-level ridging over Mexico will build into Deep South Texas providing subsidence through the period. At the surface, high pressure across the northern Gulf of Mexico will continue to slide eastward through Wednesday. The warm southeasterly flow will allow temperatures to reach the low to mid 80s across much of the area today under mostly cloudy skies. Wednesday will be warmer with near normal temperatures, highs ranging from the 70s at the beaches to the upper 80s to the lower 90s across the Rio Grande Plains.
641 AM CDT Tue Apr 23 2024 (Today and tonight) Thunderstorms may develop east of Lubbock late afternoon along a weak cold front, then move southeast into the Big Country during the late afternoon/evening hours. Otherwise warmer today, with highs reaching into the 80s, with 90 degrees possible in western portions of the Concho Valley and Big Country.
630 AM EDT Tue Apr 23 2024 High pressure will build overhead this morning, then shift to our SE this afternoon and tonight. A dry cold front will approach from the NW late tonight, then shift across the region Wednesday.

Temperatures remain a few degrees either side of normal through the week with high pressure returning behind the front. Clouds still expected to move into the region tonight, along with increasing moisture, ahead of the next cold front expected to arrive Wednesday morning. Highest rainfall amounts will be west of the Blue Ridge, generally around 0. Temperatures a few degrees cooler tomorrow, but will be windier with northwest winds gusting into the 20mph range.
An upper level trough axis will pass just off to our northeast overnight tonight through the day on Wednesday with a weak surface front moving southward from the Ohio River Valley. Clouds will increase as the front approaches overnight tonight through Wednesday morning with warmer overnight temperatures.
An trough approaching the west coast will bring shower and thunderstorm chances the next few days. Going into Wednesday, the upper trough shifts inland near SoCal, with an area of enhanced forcing and divergence aloft focusing showers and thunderstorms near and south of Hwy-50. We'll also see chances for accumulating snow in the higher elevations of the Eastern Sierra and White Mountains.
(Rest of today through Wednesday) High pressure over the SE US coast today will slide off into the western Atlantic on Wednesday.
High pressure will build in from the north thereafter but not really bring a cooldown. At this latitude, we are expecting to see a glancing influence from this trough with small height falls and weak warm advection ahead of its associated cold front. Backdoor cold front will be sagging through the area at the start of the period.
1250 PM EDT Tue Apr 23 2024 High pressure will shift southeast offshore today. A dry cold front will approach from the NW late tonight, then shift across the region Wednesday.
(This afternoon through Wednesday night) Temperatures are warming up quickly this afternoon with weak ridging overhead and westerly winds at the surface. As the dryline pushes east this afternoon, a cold front will continue to push south, approaching the northern Permian Basin early this evening. Upper ridging will remain in place tomorrow so thunderstorm coverage looks to be isolated at best, if at all.
A weakening cold front will track into the Mid-South after midnight tonight and bring a chance of showers and isolated thunderstorms to areas north of I-40 through tomorrow morning. Bumped up high temperatures for this afternoon, as current readings are running about one or two degrees warmer than previous forecast. The warming trend will continue on Wednesday, despite the passage of a weak cold front tonight.
/44/ (Tuesday through Wednesday) Quiet morning for us in the wake of exiting high pressure of 1024mb edging into Georgia now. Overnight air temps will start to see warmer readings with upper 50s and lower 60s as dew points continue upwards. The warmer start will edge highs into the lower 80s for many of our sites.
