1231 PM CDT Thu Nov 2 2023 * Breezy and warmer conditions to close out the week Broad warm advection and attendant southwesterly breezes today will help boost temperatures back into lower 50s under generally sunny to partly cloudy skies. We begin on Friday evening when a departing low level jet will pull a broad center of low pressure into the area.
1120 AM MDT Thu Nov 2 2023 Mid and high clouds continued to stream through the high pressure ridge to the west moving southeastward overhead early this morning. Clouds remain in the picture today as a short wave trough moves to the West Coast this afternoon with altostratus largely confined to the northern zones. The short wave tracks eastward over the Northwest and northern Great Basin tonight forcing the ridge eastward while it loses amplitude over the region later tonight and clouds decrease. If showers develop they shouldn't be very impactful with model output only generating an inch or two of snowfall over the higher peaks.
Southerly winds will stay up some across most of eastern Oklahoma which should keep temps above freezing for most locations, while some valley locations and portions of northwest Arkansas will likely drop to near or below freezing for another night tonight, with some areas of frost likely in those areas.
257 PM EDT Thu Nov 2 2023 (This afternoon through Friday night) Other than another night of sub-freezing conditions and patchy frost, no significant weather impacts or forecast concerns expected in the short term period. Daytime temps not too bad today (55 to 65) and will be even warmer Friday (60s). Overnight temps last night were well below freezing at many locations, especially far N and NW. May be some time until we see sub-freezing temps based on latest guidance.
311 PM CDT Thu Nov 2 2023 Gusty southwesterly winds and mostly sunny skies continue to aid in boosting temperatures into the lower to middle 50s early this afternoon. Wind speeds will then abate from northwest to southeast later Friday afternoon and evening with the approach of a cold frontal boundary. Later in the afternoon and evening, there is a non-zero chance (5 to 10%) for a few late day light showers or sprinkles across parts of northern IL as the cold frontal boundary begins to move into far northern IL.
A weak trough will move through tomorrow, which will increase winds slightly.
117 PM EDT Thu Nov 2 2023 Dry conditions with high pressure will continue into the weekend along with a gradual warming trend. Eastern CONUS high pressure and zonal flow will keep dry weather in the forecast through Friday. Mostly sunny skies are expected today, but increasing upper level moisture amid a crossing weak upper trough will bring increasing cloud cover on Friday. Most will be just below the freezing mark Friday morning.
(Tonight) Temperatures have reached the mid 50s to low 60s throughout the Tennessee Valley this afternoon under clear skies under the influence of high pressure to our northeast, over the Appalachian region. However, dry weather will continue to dominate the area due to the aforementioned high pressure. Low temperatures are forecast to drop into the low to mid 30s, however, we have officially ended our Autumn Frost/Freeze program and therefore, no Frost/Freeze products will be issued to account for this.
Snow is also expected at other higher elevation locations across NW WY, with Togwotee and Sylvan passes seeing 4 to 6 inches, and the lower elevations of Yellowstone possibly picking up 2-3 inches. As the trough axis passes through the area between 12am and 6am, a few showers are possible east of the divide early Friday morning. Cooler mid-level air settles in on Friday, but surface temperatures should remain near normal due to decent boundary layer mixing in the post-trough environment, and the fact that this this wave is from the PacNW and not southern Canada.
154 PM EDT Thu Nov 2 2023 High pressure will remain over the area into the weekend with another very cold night expected tonight. This afternoon: Strong and dry high pressure remains anchored over the Carolinas today with clear skies and light northeasterly winds around 5 to 8 mph. Temperatures are rising through the lower to mid 50s under full sunshine and should top out in the upper 50s to around 60 degrees. Tonight: Another night of well below normal temperatures expected with the axis of strong high pressure centered over the Carolinas. Local radiation scheme suggests lows in the upper 20s and this is in line or slightly cooler than the MOS guidance and NBM. General troughing will give way to zonal flow across the eastern CONUS as the deep trough quickly pulls away over the Atlantic.
Even warmer temperatures are expected tomorrow, with readings in the 70s likely.
Satellite and radar imagery show moist flow shifting across the PacNW and Idaho this afternoon into a flat upper ridge. The upper level ridge breaks down during the afternoon and evening on Sat, with a return of rain below 10000ft at first with enough southerly air flow to keep temperatures mild on Sat. Precipitation falls off Tue night, and an upper level ridge could be back in control by Thu. Wind during this unsettled period does get to the 20 to 30 mph ranges for ridges and the Snake River plain, but not to Advisory criteria.
General upper level troughing will remain over the eastern U.
204 PM EDT Thu Nov 2 2023 High pressure will build over the Mid-Atlantic through the weekend. This will result in widespread sub-freezing temperatures once again (20s to lower 30s).
Pops return with a cold front's approach and mid week passage. Early week temperatures running 5-10 degrees above normal will drop markedly back to near normal after the cold front's mid to late week passage.
ARS Cool, clear, and calm conditions are expected for the next few days as high pressure dominates.
Even with the clear skies, the steady southerly wind will keep temperatures from dropping as low as they have the past couple of morning with lows generally in the low/mid 30s. Highs tomorrow are expected to work into the low 60s for many locations across southern IN/central KY. --------------------------------------------------------------------- A cold front will approach from the northwest this weekend but it will be weak and getting weaker.
This hasn't had too much of an impact on temperatures as we have warmed up rather quickly after a chilly start, with most locations in the lower 60s at the 1PM hour. Tonight, expect another chilly one, but not nearly as cold as the last couple of nights as mid level cloud cover acts as a bit of an insulator and a return to south/southeasterly flow resumes with high pressure having moved east into the southeast CONUS.
207 PM EDT Thu Nov 2 2023 After one more chilly night tonight, the weather will trend warmer and stay dry into the weekend.
With the expected light freezing rain overnight, it was deemed prudent to issue a Winter Weather Advisory for the areas expected to receive measurable amounts of freezing rain through Friday morning. Chances for measurable freezing rain remains moderate to high (40-60%) for the areas within the Advisory, and the impacts would be significant if the freezing rain occurs as forecast, as all surfaces accumulating ice would become extremely slippery. Temperatures already warm enough across most of the ridge tops for rain, and with afternoon timing of onset, river bottom temperatures should also support rain. While the ensembles have increased the potential QPF amounts with this system, the freezing rain threat has diminished somewhat, as the highest probability for 0. 10" of accumulation is across the southwest half of the CWA, where temperatures will be warmer.
219 PM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. A weak cold front is forecast to cross our region by mid week. Strong sfc hipres will remain dominant thru Fri as it ridges in from the northeast. Highs on Fri will be held a little below normal, but modify warmer than today due to high insol. Maxes will range from the lower/mid 60s non/mtns to arnd 60 degrees over the mtn valleys.
143 PM EDT Thu Nov 2 2023 High pressure will settle over the mid-Atlantic region today, remaining there through the weekend.
(This evening through Friday) The warming trend continues Friday as the lee trough along the Texas and New Mexico state line strengthens, and south to southwest winds become gusty at times.
- Very warm Friday (90-100% chance) - Mild weekend into next business week The lee trough will reform across the high plains of Colorado this evening. This matches well with the EPS, which shows 90-100% chance of highs warmer than 70F. Afternoon relative humidity looks to only bottom out in the 15 to 20% range and winds associated with the weak sfc trof should be light as there isnât much winds in the boundary layer. No significant UL trofs are expected to traverse across the FA with any resultant weather. Generally zonal flow aloft and weak lee troughing at the sfc.
Breezy northeasterly winds continue with the area between strong high pressure off the coast of the mid-Atlantic and weak troughing developing along our coast. Overnight lows will range from the low 40s inland SE GA to the low 60s along the NE FL coast.
Issued by National Weather Service State College PA 140 PM EDT Thu Nov 2 2023 A large area of high pressure will become our dominant weather feature through most of the upcoming weekend. As an upper trough slowly lifts out to the northeast and surface ridging establishes itself, at least partly sunny days with above normal temperatures for early November should be the rule.
Further to the north, a trough over Ontario will interact with high pressure to our southeast, strengthening the MSLP gradient over Indiana. Temperatures will be a bit warmer today given increasing southerly flow and modest warm air advection. Gradient induced winds overnight, while not as gusty, should help keep temps above freezing in many locations. A few pockets of sub-freezing air may still develop especially in sheltered areas / valleys.
Cold front settles into the CWA from the north Friday.
High clouds will gradually move across the region this evening and overnight as a high pressure system weakens and west/southwest low-level flow and WAA spread across the region.
This is tied to low level moisture rising above the modified (yet still cooler) air mass. Increased cloud cover will result in low temperatures tonight a few degrees warmer than last night, ranging from the upper 50s to low 60s.
For today, temperatures will be warmer than yesterday, generally 70 degrees. Deep dry west flow pattern with upper level ridging will keep conditions dry with skies clear and light and generally variable winds through the period. Starting Friday, min humidity will be critical across the lowlands and 16 to 25 percent in the higher terrain.
However, warming is occurring and most valley locations have now warmed to several degrees above freezing. This trend will continue into tonight, and with precipitation and cloud cover continuing, we do not expect to see temperatures drop much below freezing tonight. And in fact, by this evening, snow levels are expected to rise to 8000 feet or higher, meaning all but the highest mountain peaks should see rain.
140 PM EDT Thu Nov 2 2023 Warmer today compared to the past few days, with highs in the upper 40s to low 50s. While lows drop to near to below freezing tonight, a hard freeze is not expected. Southwest winds could gust up to 20-25 mph at times today (and again Friday), transporting much warmer air northward. Tonight, lows will be near freezing with breezy conditions continuing.
1147 AM EDT Thu Nov 2 2023 High pressure, centered over West Virginia this morning, will slowly push to the Mid Atlantic coast over the next several days. Meanwhile, a dying cold front will stall out just north of the state this weekend.
Even with the clear skies, the steady southerly wind will keep temperatures from dropping as low as they have the past couple of mornings with lows generally in the low/mid 30s. Highs tomorrow are expected to work into the low 60s for many locations across southern IN/central KY. --------------------------------------------------------------------- A cold front will approach from the northwest this weekend but it will be weak and getting weaker.
Increasing H50 thickness and height values, combined with relatively light southwest surface flow in response to lee surface pressure falls in northeast New Mexico during the day tomorrow will lift temperatures into the low to mid 70s under mostly sunny skies. Friday morning low temperatures will also be warmer than the past few days as our gradual warm up, both day and night, continues into the weekend.
A weak disturbance and cold front will bring more clouds than sun over the weekend along with a few showers mainly for areas north and west of the Capital District. High pressure will remain situated to the south and east of the region through Friday afternoon. An upper-level trough and weak cold front will begin to approach the region Friday night. The main forcing with the upper trough will pass to the north of the region.
255 PM CDT Thu Nov 2 2023 Key Messages: * A cold front will move through the area tonight bringing increasing cloud cover to the area Friday.
147 PM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. A weak cold front is forecast to cross our region by mid week. Fair, cool, and dry across the region through the next 24 hours as a nearly zonal flow aloft hold high pressure at the surface over the Carolinas/Mid-Atlantic. Temps should recover maybe a category warmer this afternoon, but still on the order of ten degrees below normal, under lots of sunshine.
241 PM EDT Thu Nov 2 2023 After one more chilly night tonight, the weather will trend warmer into the weekend. The high sliding off to the east will allow for some light S'ly winds to persist on ridgetops tonight, but many valley locations could decouple and go calm. As a result, while overall we expect a less frigid night than last night, valley locations could easily drop at least 5 degrees cooler than surrounding higher elevations, and essentially the entire area will dip to or below freezing. High pressure slides east into the Atlantic as a weak front drops into the Ohio Valley heading into the weekend.
1154 AM CDT Thu Nov 2 2023 (Rest of Today) Below-freezing temperatures this morning have warmed into the low to mid 30s throughout most of the Tennessee Valley and are forecast to continue rising into the upper 50s to low 60s by this afternoon. High pressure to our east will allow us to have clear skies today and continued dry conditions.
715 PM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. A weak cold front is forecast to cross our region by mid week. Strong sfc hipres will remain dominant thru Fri as it ridges in from the northeast. Highs on Fri will be held a little below normal, but modify warmer than today due to high insolation. Maxes will range from the lower/mid 60s non/mtns to arnd 60 degrees over the mtn valleys.
618 PM CDT Thu Nov 2 2023 (This evening through Friday Night) High pressure has moved eastward into the Gulf of Mexico, allowing onshore flow to return this afternoon. Lows tonight will be slightly warmer than the last couple of nights, with temperatures in the 40s and 50s. Lows on Friday night will be slightly warmer than tonight, with temperatures in the upper 40s to near 60.
933 PM EDT Thu Nov 2 2023 High pressure will keep conditions mainly dry through the weekend, although a weak front nearby may bring a few showers to Central NY at times.
Key Messages: * A cold front will move through the area tonight bringing increasing cloud cover to the area Friday.
710 PM EDT Thu Nov 2 2023 High pressure will slowly translate to the Mid Atlantic coast through Friday bringing dry and milder conditions. Meanwhile, a dying cold front will stall out just north of the state this weekend.
Short Term Update - The previously mentioned high will build out further off the northeast Atlantic coast but will maintain a hefty ridge across the southeast. While showers cannot be ruled out, the best region for their formation will remain across the warmer Atlantic waters. A powerful ridge will remain anchored over the southeastern United States and will maintain strong and gusty northeasterly breezes across Keys waters through the overnight period.
A weak upper level trof will traverse the region through the day Friday, but with an extremely dry column overhead (0.
Normally colder spots should dip near or below freezing once again. An afternoon that's 10 degrees warmer than today seemed a stretch for what will be just insolation from weak sun angles (as opposed to actual advection).
A weak cold front will cross northern Utah tonight.
845 PM EDT Thu Nov 2 2023 High pressure will slowly translate to the Mid Atlantic coast through Friday bringing dry and milder conditions. Meanwhile, a dying cold front will stall out just north of the state this weekend.
759 PM EDT Thu Nov 2 2023 Breezy northeasterly winds continue with the area between strong high pressure off the coast of the mid-Atlantic and weak troughing developing along our coast. Overnight lows will range from the low 40s inland SE GA to the low 60s along the NE FL coast.
957 PM EDT Thu Nov 2 2023 Dry high pressure continues over our region through the weekend and into the next work week. A weak cold front is forecast to cross our region by mid week. Strong sfc hipres will remain dominant thru Fri as it ridges in from the northeast. Highs on Fri will be held a little below normal, but modify warmer than today due to high insolation. Maxes will range from the lower/mid 60s non/mtns to arnd 60 degrees over the mtn valleys.
750 PM EDT Thu Nov 2 2023 High pressure will keep conditions mainly dry through the weekend, although a weak front nearby may bring a few showers to Central NY at times.
909 PM EDT Thu Nov 2 2023 High pressure to the north and a trough to the south is keeping a tight pressure gradient across the area.
Most inland locations should dip to near or below freezing once again. An afternoon that's 10 degrees warmer than today seemed a stretch for what will be just insolation from weak sun angles (as opposed to actual advection).
These winds should help to keep us a bit warmer than last night but lows will still be in the low to mid 30s with some 20s possible. A weak trough will move through tomorrow, which will increase winds slightly.
High pressure and a very dry airmass will keep overnight lows cold and near freezing. Some moderation as we hit Friday afternoon with highs about 5 degrees warmer area wide. 75 Previous short-term discussion: (This afternoon through Friday) A cold and dry airmass remains in place over the Southeast as a high pressure center moves east over the Mid-Atlantic region. Highs will reach the low to mid 60s today then upper 60s to lower 70s tomorrow with plenty of sun and a mostly cloudless sky. We'll have another night with most areas at or below freezing.
647 PM EDT Thu Nov 2 2023 High pressure will keep conditions mainly dry through the weekend, although a weak front nearby may bring a few showers to Central NY at times.
928 PM EDT Thu Nov 2 2023 High pressure continues across the area tonight. (This afternoon through Friday night) Other than another night of sub-freezing conditions and patchy frost, no significant weather impacts or forecast concerns expected in the short term period. Daytime temps not too bad today (55 to 65) and will be even warmer Friday (60s). Overnight temps last night were well below freezing at many locations, especially far N and NW. May be some time until we see sub-freezing temps based on latest guidance.
Some brief high cloudiness may pass to our north overnight, but not expecting cloud cover this far south, even though an upper level trough axis will be approaching the area around daybreak. Warm air advection and maybe some slightly more persistent winds in our highest elevations could keep temperatures from dropping much below the lower to mid 30s.
307 PM MDT Thu Nov 2 2023 A collapsing ridge begins to flatten out the upper level flow over the region this afternoon and early this evening. Although, some gusty winds will likely mix down onto the higher terrain features of northwest Colorado Friday afternoon.
530 PM MDT Thu Nov 2 2023 A collapsing ridge begins to flatten out the upper level flow over the region this afternoon and early this evening. Although, some gusty winds will likely mix down onto the higher terrain features of northwest Colorado Friday afternoon.
Light southerly flow across the region will keep temps a little warmer than previous nights with readings mainly in the low to mid 30s.
703 PM EDT Thu Nov 2 2023 (Through Friday) Seasonably cool and quiet conditions are expected to persist through the day tomorrow, with high temperatures generally remaining near average (in the 70s) and low temperatures remaining below average (from the low 40s in Alabama and Georgia to the low 50s in the southeast Big Bend).
(This afternoon through Friday night) Other than another night of sub-freezing conditions and patchy frost, no significant weather impacts or forecast concerns expected in the short term period. Daytime temps not too bad today (55 to 65) and will be even warmer Friday (60s). Overnight temps last night were well below freezing at many locations, especially far N and NW. May be some time until we see sub-freezing temps based on latest guidance.
659 PM CDT Thu Nov 2 2023 (Tonight) Temperatures have reached the mid 50s to low 60s throughout the Tennessee Valley this afternoon under clear skies under the influence of high pressure to our northeast, over the Appalachian region. However, dry weather will continue to dominate the area due to the aforementioned high pressure. Low temperatures are forecast to drop into the low to mid 30s, however, we have officially ended our Autumn Frost/Freeze program and therefore, no Frost/Freeze products will be issued to account for this.
1056 PM EDT Thu Nov 2 2023 High pressure will slowly translate to the Mid Atlantic coast through Friday bringing dry and milder conditions. Meanwhile, a dying cold front will stall out just north of the state this weekend.
High pressure at the surface was now centered just to the east of the Appalachians this evening. Expect the temperatures to continue falling with temperatures reaching the freezing mark and lower again by early Friday morning but a couple degrees warmer than this mornings lows.
803 PM EDT Thu Nov 2 2023 After one more chilly night tonight, the weather will trend warmer into the weekend. It's another starry night outside as high pressure maintains clear skies. The high sliding off to the east will allow for some light S'ly winds to persist on ridgetops tonight, but many valley locations could decouple and go calm. As a result, while overall we expect a less frigid night than last night, valley locations could easily drop at least 5 degrees cooler than surrounding higher elevations, and essentially the entire area will dip to or below freezing. High pressure slides east into the Atlantic as a weak front drops into the Ohio Valley heading into the weekend.
Light winds and clear skies will allow for good radiational cooling tonight, so nudged tonights Min temps slightly cooler to latest guidance values that usually work well in these cases. Current dew point values are sitting just below freezing, so expect this to be a reasonable floor for cooling potential. Tomorrows high temperature will be in the low to mid 70s.
806 PM EDT Thu Nov 2 2023 High pressure will remain over the area into the weekend with another very cold night expected tonight. High pressure over the area will keep winds light to calm and skies abundantly clear overnight, resulting in ideal radiational cooling. General troughing will give way to zonal flow across the eastern CONUS as the deep trough quickly pulls away over the Atlantic.
