Aikyam-Lab/Synoptic-Bench huggingface dataset:
Tonight and Thursday Warmer weather made a comeback this afternoon as increasing return flow ushered in temperatures in the upper 60s to low 70s. Southwest winds likewise began to ramp up late this morning and early afternoon as the pressure gradient tightened up between approaching low pressure to the northwest and departing high pressure to the southeast. A weak cold front will sweep southeast across the forecast area late tonight, although an abundance of dry air/building high pressure over the Plains should keep us dry. Expect post-frontal temperatures on Thursday to drop into the low to mid 60s across the Northwoods to the low 70s in the Fox Valley (~5 to 10 degrees above average).
The zonal pattern in place today will change to subtle 500mb ridging by Friday. At the surface, the cold front has almost made it through the entire FA now, resulting in a short period of gustier winds.
210 AM EDT Thu Oct 3 2024 Fog this morning, then a dry Thursday under high pressure. Fog has quickly developed across portions of the WV lowlands into the higher terrain. Cold front is exiting our mountain counties, with plenty of low level clouds and moisture in its wake. High temperatures across the lowlands will generally top out in the upper 70s to lower 80s. High pressure anchored over the Great Lakes for the end of the work week will yield northwesterly flow at the surface, but afternoon highs are still progged to hover above normal Friday afternoon. Should see the lowlands once again tip above the 80 degree mark and for the mountains observing highs in the 60s/70s.
118 AM EDT Thu Oct 3 2024 (Rest of today through Thursday) A respite from an more active weather pattern continues across South Florida as we remain anchored underneath a mid-level ridge aloft. Accordingly, the highest chances for showers and storms today will be focused around the Lake Okeechobee region, coincident with the most available moisture, and inland portions of the peninsula where sea breeze collisions will occur. With a mid-level trough advecting into the western Atlantic waters offshore of the mid-Atlantic/northeastern United States on Thursday, with mid-level ridging remaining situated over our region. Maximum temperatures will reach the lower to mid 90s in most areas both days with overnight lows in the 70s.
(Today) High pressure at the surface and aloft, situated over the eastern Lower-48 controlled this region's sensible weather. An advection of low/mid level stratus from the ESE could become a factor in attenuating the development of more fog, by blocking long wave radiation to space and slowing the cooling effect of clear skies. Later today, warmer conditions are expected as a southerly flow returns and higher heights are realized.
After fog dissipated later this morning, should be a very nice day and considerably warmer than yesterday with highs in the low to mid 80s. (Friday through next Thursday) 00Z guidance continues to depict a weak upper trough moving across Middle Tennessee on Friday, with southerly flow bringing dewpoints up into the 60s.
434 AM EDT Thu Oct 3 2024 A slow moving, weak cold front will dissipate across the area tonight, with showers slowly diminishing.
1227 AM CDT Thu Oct 3 2024 (Tonight through Thursday night) Ridging will continue over most of the area tonight with a very low chance of showers (<10%) over the waters. A broad trough over the southwestern Caribbean Sea and southern Gulf of Mexico will move further into the Gulf of Mexico, increasing our moisture. This will combine with a mid-level trough/cut-off low that will drift to the east across the area resulting in low to moderate (10-50%) rain chances will increase for Thursday night over the waters.
(Today through Friday Night) Dry conditions will persist across the state through the short term portion of the forecast (and beyond) as ridging aloft and at the sfc remain over the region. Temperatures are expected to be warmer than yesterday across the state with Td values bottoming out in the 40s/50s F by this afternoon. Normal highs for early October range from the mid 70s F to the lower 80s F which means daytime highs will be about 10-15 degrees above normal by Friday.
We're also watching an approaching inverted trough/tropical wave approach from the east, this will lead to an increase in low level moisture over the next 24-36 hours, especially near the coast.
1005 PM CDT Wed Oct 2 2024 Sfc ridging remains in place across the region this evening, with little change in placement expected over the next 24hrs as it lingers from the OH Valley SW into ECntrl TX.
257 AM MDT Thu Oct 3 2024 - Cooler temperatures are expected today behind a front.
310 AM EDT Thu Oct 3 2024 Dry high pressure filters into the region today before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms, back to the mountains. Drier conditions return this weekend as high pressure builds back into the region.
The band of deeper moisture remains across most of the region today with easterly flow (Sea Breeze Regime 2) becoming established as high pressure builds south.
It will be colder tonight, and the typical wind protected valleys will observe subfreezing overnight temperatures. They have already observed a hard freeze with the previous cold front. Confidence in this area getting below freezing is 80%. High pressure aloft will strengthen on Thursday for a slight warming trend and decreasing RHs. Another cold front is set to arrive on Friday. This front is different from the previous two cold fronts we have observed the past couple of weeks and will not have the same impacts in terms of blowing dust and super dry air that follows.
216 AM MDT Thu Oct 3 2024 - A respite in fire weather conditions for Thursday as a cold front sags into the area from the north.
118 AM EDT Thu Oct 3 2024 Temperatures this evening were a degree or two warmer than the same time last night, with dewpoints a degree or so lower. Aloft an upper ridge will translate through the southeastern US, and by tomorrow we'll return to a weak southwesterly flow under the near surface ridging regime. Despite the passage of a front this morning, dewpoints will remain relatively unchanged, and the different ridge positions will actually increase tomorrow's temperatures by a few degrees relative to today.
The zonal pattern in place today will change to subtle 500mb ridging by Friday.
1000 AM EDT Thu Oct 3 2024 Weak high pressure will nose into the region from the north this afternoon through Friday.
638 AM EDT Thu Oct 3 2024 Dry high pressure filters into the region today before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms, back to the mountains. Drier conditions return this weekend as high pressure builds back into the region.
High pressure will build to our south this afternoon through Friday.
The ridge that has held steady over the region will finally start to weaken today.
Issued by National Weather Service Huntsville AL 942 AM CDT Thu Oct 3 2024 High pressure over the Mid South will continue to build south and east into the lower Mississippi Valley and ArkLaMiss as a gradual warming trend continues today. Still, ample sunshine and light ESE flow will help warm temperatures into the mid/upper 80s -- to potentially the lower 90s this afternoon.
Persistent high pressure across the southwestern US will keep high temperatures 10 to 15 degrees above normal today, with record to near record warmth across central NV. Trough energy approaching the Pacific NW coast tonight moves onshore with the axis reaching eastern WA and OR by Friday afternoon. As this trough approaches from the NW the ridge across the southwestern US will shift eastward, with the flow aloft across NV becoming southwesterly. Lightest winds on Friday will be south of the Highway 50 corridor where gusts of 20 to 25 mph are expected in the afternoon and early evening hours.
526 AM MDT Thu Oct 3 2024 - Cooler temperatures are expected today behind a front.
529 AM MDT Thu Oct 3 2024 - Another record high possible for KALS, but plains will be cooler (but still above normal) as a front pushes across later this AM.
326 AM MDT Thu Oct 3 2024 - Another record high possible for KALS, but plains will be cooler (but still above normal) as a front pushes across later this AM.
Tonight lows will be warmer given the increased cloud cover and rain chances, with lows bottoming out in the upper 60's to lower 70's for most locations and middle 70's nearer the coast. Friday will be noticeably cooler for the same reason, with highs only making it into the upper 70's and lower 80's, warmest nearer the coast.
Did lower dew points a touch to be in the lower to mid 60s through the day based on Hi-Res guidance.
Current observations across the Reef averaging around 5 knots but as the low develops winds will start to freshen today. Mean layer ridging over the Central Caribbean will dissipate over the next few days. This will result in the Gulf having lower heights and a positively tilted upper-level trough to its northwest, which will promote weather makers down below. PoPs have been increased as a broad low-pressure system stays parked to our west and deep tropical moisture dominates our area.
High pressure remains in control of the Southwest CONUS and the high temperature records keep falling. Will continue to lean toward the warmer guidance and above in some places such as here at Grand Junction where the 75th percentile or higher of guidance has been working out. It could be slightly cooler across the North today as an almost indiscernible front wavers near the border and heights are suppressed just a bit by a wave passing well to the North. Heights spring back up tomorrow as the ridge central settle over the Southern Rockies and the upper flow pattern backs around to the Southwest.
By this afternoon flow aloft will become southerly as ridging builds over the southern states and a southern stream develops over the region.
1058 AM EDT Thu Oct 3 2024 High pressure to the north has bridged the old frontal trough that was draped across central FL which is resulting in a steadier onshore (ENE-E) flow today.
639 AM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
611 AM CDT Thu Oct 3 2024 (Today and tonight) The forecast area will remain underneath a weak mid/upper level trough that is wedged between upper ridging over the desert southwest and the southeastern CONUS. The ridge to the west will begin to expand eastward tonight as a fast-moving trough in the northern stream treks from the Dakotas to the western Great Lakes. This trough will also push a weak cold front into, and possibly through, the forecast area by sunrise Friday and will result in cooler overnight lows, especially across the northwestern third to half of the forecast area.
The ridge still dominates the weather pattern over Interior Central California today.
503 AM EDT Thu Oct 3 2024 An upper ridge will begin building into the area today. High pressure builds in behind a dry front midweek with continued dry conditions Thursday and Friday. This will do little to change the overall weather pattern with highs once again in the low to mid 80s and light easterly winds.
506 AM MDT Thu Oct 3 2024 - Breezy to windy conditions at times this morning behind a cold front.
Temperatures at 2 AM PDT ranged around the low 70s in much of the Valley. High temperatures will remain well above normal today, with Valley conditions reaching the high 90s to low 100s again, accompanied by widespread Moderate HeatRisk (areas of Major HeatRisk today in the foothills).
544 AM CDT Thu Oct 3 2024 - A cold front will trigger scattered light showers late tonight into Friday morning. A cold front currently extending from Lake Superior southwestward to Nebraska will sink slowly southward today. Thermal ridging ahead of the boundary will boost 850mb temps into the 15-17C range, resulting in afternoon high temperatures topping out in the upper 70s to lower 80s. 25 along/west of a Galesburg to Beardstown line where moisture transport via the low-level jet will be greatest. Given cloud cover and morning showers, temperatures will be a bit cooler on Friday with highs ranging from the middle 70s along/north of I-74 to the lower 80s south of I-70.
935 AM EDT Thu Oct 3 2024 Dry high pressure filters into the region today before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms, back to the mountains. Drier conditions return this weekend as high pressure builds back into the region.
516 AM CDT Thu Oct 3 2024 (Today through Friday Night) Dry conditions will persist across the state through the short term portion of the forecast (and beyond) as ridging aloft and at the sfc remain over the region. Temperatures are expected to be warmer than yesterday across the state with Td values bottoming out in the 40s/50s F by this afternoon. Normal highs for early October range from the mid 70s F to the lower 80s F which means daytime highs will be about 10-15 degrees above normal by Friday.
636 AM CDT Thu Oct 3 2024 (Today) High pressure at the surface and aloft, situated over the eastern Lower-48 controlled this region's sensible weather. An advection of low/mid level stratus from the ESE could become a factor in attenuating the development of more fog, by blocking long wave radiation to space and slowing the cooling effect of clear skies. Later today, warmer conditions are expected as a southerly flow returns and higher heights are realized.
- Warm Thursday with Isolated Showers Possible Thursday Night Weather for Thursday will feel more like late summer as 850mb temps in the low teens combine with ample sunshine to bring highs in the mid 70s. An advancing high and northerly flow brings slightly cooler temps with highs around 70.
613 AM CDT Thu Oct 3 2024 Updated at 610 AM CDT Thu Oct 3 2024 - Warm and dry weather with worsening drought conditions for the foreseeable future (Today and tonight) Today will be a hot day as the low-level thermal ridge strengthens ahead of an advancing cold front that will move southward across the Plains. The Grand Ensemble of GEFS, GEPS, and ENS members has a mean 850 mb temperatures ranging from 20 to 25 deg C with the highest values across western into north central Oklahoma. Probabilistic guidance has about a ~30% for locations across north central Oklahoma to reach 100 deg F, which is reasonable given the location of the low-level thermal ridge.
While this slow exit will leave us warm and dry over the mid-week, it will allow for a weak cold frontal boundary to sneak into the far northwester portions of the Panhandles Thursday into Friday.
631 AM CDT Thu Oct 3 2024 (Today through Friday) Upper level ridge will shift eastward today, as a northern stream trough crosses the northern Plains and broad troughing breaks off over Texas.
640 AM EDT Thu Oct 3 2024 Weak high pressure will nose into the region from the north this afternoon through Friday.
610 AM EDT Thu Oct 3 2024 High pressure builds in from the southwest today providing fair weather and a warming trend into Friday.
529 AM MDT Thu Oct 3 2024 - A respite in fire weather conditions for Thursday as a cold front sags into the area from the north.
1050 AM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
628 AM EDT Thu Oct 3 2024 - Warmer today with temperatures climbing well into the 70s.
/Issued 1256 AM CDT Thu Oct 3 2024/ /Through Friday/ A strong mid-level ridge axis along with a return to southeasterly low-level flow will contribute to well above normal highs the next couple of afternoons with readings in the 90s. /Issued 232 AM CDT Thu Oct 3 2024/ /Friday Night Onward/ A dry and unseasonably hot period will continue this weekend as a strong mid level ridge remains anchored from the southern Rockies to the Southern Plains. Even though the ridge will briefly become compromised on its southern flank by an upper low over South Texas, subsidence associated with the much larger ridge will most likely suppress any convective attempts this weekend.
934 AM EDT Thu Oct 3 2024 High pressure builds in from the southwest today providing fair weather and a warming trend into Friday.
718 AM EDT Thu Oct 3 2024 (Today through Friday) The mid-level ridge will continue to hold over South Florida on Thursday, with a batch of drier air still lingering as well mainly in the southernmost counties (Miami-Dade, Monroe, parts of Broward and Collier). On Friday, an easterly trough will progress into the central Gulf of Mexico. Temperatures will generally be in the low 90s across South Florida for the end of this week with heat indices staying below advisory criteria due to the drier air cluster, which keeps dew points slightly lower.
611 AM CDT Thu Oct 3 2024 (Today through Friday) Broad high pressure over Texas combined with lower pressure centered over the Bay of Campeche to the south will support the ongoing but somewhat unusual light to moderate northeast wind regime. Immediate tropical cyclone formation chances remain negligible through 48 hours. Rain chances seem to be confined to the Gulf today, but will increase for Kenedy County and the lower RGV on Friday. Daytime high temperatures will trend slightly warmer than normal, in the lower 90s, with overnight low temperatures near normal in the upper 60s to near 70.
1046 AM MDT Thu Oct 3 2024 - Breezy to windy conditions at times this morning behind a cold front.
246 PM EDT Thu Oct 3 2024 Dry high pressure moves off the East Coast tonight before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms to the mountains. Drier conditions return over the weekend as high pressure builds back into the region.
The ridge axis shifts overhead Friday afternoon and high temperatures are expected to best records once again. A weak shot of cooler/drier air should help with Friday night low temperatures again. This could inhibit radiational cooling enough to affect lows, but it looks like we see lows pretty close to recent mornings, if not a couple degrees cooler.
Friday will be even warmer than today with Highs in the mid to maybe even upper 80s.
A highly amplified ridge will remain entrenched over the region through the weekend, with temperatures continuing to run about 15 degrees above normal.
1123 AM CDT Thu Oct 3 2024 - A few light showers tonight with a cold front.
This is due to a low pressure system to the north skirting past the area.
1157 AM CDT Thu Oct 3 2024 Updated at 1155 AM CDT Thu Oct 3 2024 - Warm and dry weather with worsening drought conditions for the foreseeable future (Today and tonight) Today will be a hot day as the low-level thermal ridge strengthens ahead of an advancing cold front that will move southward across the Plains. The Grand Ensemble of GEFS, GEPS, and ENS members has a mean 850 mb temperatures ranging from 20 to 25 deg C with the highest values across western into north central Oklahoma. Probabilistic guidance has about a ~30% for locations across north central Oklahoma to reach 100 deg F, which is reasonable given the location of the low-level thermal ridge.
Areas of fog have moved further inland, with the lowest visibilities on the coastal mesas so far this morning. As a ridge of high pressure builds back over Southern California, the marine layer is expected to become shallower and staying confined to the coast.
The region remains anchored underneath a mid- level ridge aloft with light flow throughout the vertical column. This will act to focus the best convergence and rain chances across inland areas this afternoon with a foci in the Lake Okeechobee region where precipitable water values remain the highest for the time being. Temperatures will generally be in the low 90s across South Florida for the end of this week with heat indices staying below advisory criteria due to the drier air cluster, which keeps dew points slightly lower.
1052 AM MDT Thu Oct 3 2024 - Cooler temperatures are expected today behind a front.
After a chilly start, steady 850mb warm advection during the day looks to result in highs about 10 degrees warmer than today. Strong 850mb warm advection continues Friday night, with some low level wind shear possible due to the strong winds expected in the low layers.
Elsewhere, precipitation chances remain on the low side through sunset. High pressure to the north has bridged the old frontal trough that was draped across central FL which is resulting in a steadier onshore (ENE-E) flow today.
A warmer air mass continues to advect into the region from the west this afternoon. Highs will continue to warm into the lower/mid 80s across central Missouri with upper 80s to around 90 occurring elsewhere. Lows tonight will be in the middle 50s to the lower 60s. An upper level trough is currently over the northern plains and will move east into the Great Lakes region tonight into Friday. Temperatures will be a few degrees cooler tomorrow than today along and north of I-44 with temperatures south of I-44 being similar to what is occurring today as the front stalls over the area.
1257 PM CDT Thu Oct 3 2024 (Today through Friday) High pressure will get nudged east today as a mid-level low moves into South Central Texas. Unfortunately, there isn't nearly enough moisture in the column to take advantage of the lift associated with this low. Afternoons will be a different story, with continued above normal highs in the lower to middle 90s.
(Tonight through Friday night) Water vapor imagery shows an upper low over north-central Mexico, with ridging over much of central and north Texas. Look for lows to drop into the lower 60s to near 70 degrees.
144 PM EDT Thu Oct 3 2024 Dry today under high pressure.
400 PM CDT Thu Oct 3 2024 - A few light showers tonight with a cold front.
Issued by National Weather Service Huntsville AL 1210 PM CDT Thu Oct 3 2024 High pressure over the Mid South will continue to build south and east into the lower Mississippi Valley and ArkLaMiss as a gradual warming trend continues today. Still, ample sunshine and light ESE flow will help warm temperatures into the mid/upper 80s -- to potentially the lower 90s this afternoon.
1047 AM MDT Thu Oct 3 2024 - Another record high possible for KALS, but plains will be cooler (but still above normal) as a front pushes across later this AM.
112 PM EDT Thu Oct 3 2024 - Sunny and warm weather today transitions toward cloudy conditions and closer to normal temperatures Friday as a cold front moves across Lower Michigan.
Temperatures on Friday will be cooler than the last few days given the increased cloud cover and rain chances.
(This evening through Friday Night) Leading edge of a elongated coastal trof stretching from the Bay of Campeche to the wcntl LA waters will continue to slowly track westward and a bit further into the TX coastal waters tonight into the weekend.
158 PM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
The trough will shift eastward across Central AL through tomorrow. Once the mid-level trough passes through, dry air will begin filtering back in from the northwest with rain chances decreasing late in the day tomorrow.
146 PM EDT Thu Oct 3 2024 Weak high pressure will nose into the region from the north this afternoon through Friday.
129 PM EDT Thu Oct 3 2024 Dry high pressure moves off the East Coast tonight before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms to the mountains. Drier conditions return over the weekend as high pressure builds back into the region.
Lows tonight drop into the upper 50s to lower 60s before a very weak cold front moves into the Permian Basin. Cold front is a misnomer, it is a wind shift as temperatures behind the front aren't any cooler than ahead of the front. Consider yourself lucky if highs are a degree or two cooler tomorrow.
In turn, temperatures will begin to slightly rebound over the next 36-hours, with highs tomorrow ranging in the low to mid-90s. Overnight lows will begin to rebound as well, with lows tonight dropping into the upper-50s and low 60s, before climbing into the low and upper-60s by tomorrow.
