Aikyam-Lab/Synoptic-Bench huggingface dataset:
This cold front will continue to slide southeast today which will keep temperatures fairly steady and in the low 30s over our northern areas to around 50 along the Kansas and Missouri border.
Overnight temperatures will range from the low 20s for northwestern counties to low 30s into south central Kansas. Otherwise, expect a cold front to push through during the morning hours turning winds out of the north. Afternoon high temperatures will still be warmer than the previous day due to downsloping winds pushing into the 50s for all of the CWA, warmest into the south central counties.
222 AM EST Thu Nov 12 2020 A cold front will push off to the southeast of the CWA overnight. High pressure building into the Ohio Valley will bring cooler and drier weather to the region for late in the week.
920 PM CST Wed Nov 11 2020 In wake of a cold front, light rain has tapered off but plenty of low cloud cover remains. These clouds will be slow to clear overnight, thanks to the moist boundary layer conditions at the low levels.
Upgraded the High Wind Watch to a Warning for WY Zone 110. A cold front currently positioned over northeast Wyoming will sweep south through the Nebraska Panhandle this evening with northerly winds and slightly cooler temperatures. Additional forcing from the front along with upslope flow along the Pine Ridge will support snowfall tonight across Converse and Niobrara Counties in Wyoming and over towards Chadron and the northern Nebraska Panhandle.
1118 PM EST Wed Nov 11 2020 A cold front will push off to the southeast of the CWA overnight. High pressure building into the Ohio Valley will bring cooler and drier weather to the region for late in the week.
1107 PM EST Wed Nov 11 2020 A cold front will push off to the southeast of the CWA overnight. High pressure building into the Ohio Valley will bring cooler and drier weather to the region for late in the week.
1210 AM EST Thu Nov 12 2020 Aviation - Weak front to move through the area Thursday night - Stronger system expected over the weekend - Temperatures mostly back to reality for the next 7 days -- Weak front to move through the area Thursday night -- Clouds will clear this evening as temperatures warm in the lowest 5,000ft. A weak cold front will approach the area Thursday night and increase moisture below 5,000ft.
1053 PM CST Wed Nov 11 2020 For the 06Z TAFs, a weak cold front will move across the terminal sites on Thursday, with winds becoming north to northeast. /Issued 533 PM CST Wed Nov 11 2020/ For the 00Z TAFs, a weak cold front will move across the terminal sites on Thursday, with winds becoming north to northeast.
The center of high pressure remains overhead or just east of the region during the day. Area of stratus/strato-cu downwind of Lake Michigan will steadily erode into this evening as drier air associated with approaching high pressure works east into the region. This will bring clear skies by late this evening/overnight with temperatures dropping into the upper 20s to lower 30s as wind speeds continue to weaken as the pressure gradient slackens with the building high pressure. This high will build across the area on Thursday and provide sunny skies and seasonable temperatures around 50 degrees.
213 AM CST Thu Nov 12 2020 Cold front that brought rain to Middle Tennessee yesterday has moved off to the east, with much cooler temperatures in the 40s to low 50s at present.
Models are hinting that a trough-like feature to our west and northwest could spawn some showers towards dawn. Regardless, an expansive high pressure dropping down across the Central Plains will nose into the Gulf of Mexico starting Thursday, bringing additional dry air. An expansive high pressure will nose in from the northwest during the day on Thursday leading to a col and a further slackening of winds.
The higher coverage of high clouds over southeast CO will continue to exit to the east this evening. Still think the highest chances for this snow will be along/north of Cottonwood Pass, with the window of highest potential expected to be from around midnight through early to mid morning on Thursday. Also did not really stray from previous thoughts on the winds and temperatures tonight, with gusty conditions expected to continue for the higher terrain and remain possible for areas lee of the Eastern Mountains, and west of I-25. Gusts up to 40 mph still possible for these locations in the lower terrain, and once again will support warmer low temps tonight.
1228 AM CST Thu Nov 12 2020 Updated for 06Z aviation discussion 06Z TAF discussion: The cold front is almost through the region early this morning. A cold front has now passed through the ArkLaMiss tonight dropping low temps into the mid 40s across the Delta region and low to mid 50s elsewhere. The front will exit the region this evening, but in its wake, some non-trivial amount of moisture will linger in the low levels particularly across south and east portions of the area.
/Today through Wednesday/ Quiet conditions remained in place overnight across the area with high pressure to the south allowing for light southerly winds into the state.
1141 PM CST Wed Nov 11 2020 VFR dry with broad cyclonic flow aloft but lacking disturbances other than an upper trough passing far to the north. Winds will begin to veer to the west as a cold front begins to drop southward across the foothills of the Rockies. The cold front should be moving into our northern counties by noon tomorrow before pushing through the FA by sunset. Highs tomorrow should not be greatly affected by the cold front given it will be passive and slow moving. Winds behind the cold front will be out of the northeast gusting to 20-25 mph. Late Thursday, a cold front will move from the Central Plains into the area thanks to a trough traversing the Midwest.
High pressure ridge extended from MO to IL bringing wall-to-wall sunshine and southwest winds to the dvn cwa. Tonight: Clear with a light south wind and lows in the upper 20s to lower 30s, as the high pressure slips slowly to our east. This is ahead of a deepening trough in the Upper Midwest.
Highs will be in the low to mid 60s today with lows tonight ranging from the mid 20s (northwest) to the mid 30s (southeast).
110 AM EST Thu Nov 12 2020 Dry and cooler headed into the weekend.
1255 AM EST Thu Nov 12 2020 Drier air will move into the region tonight as high pressure builds into the Great Lakes. High pressure will continue to provide dry weather and seasonal temperatures the rest of the week into the start of the weekend. Much cooler air will be moving into the region with lows in the 30s across most locations overnight. On Thursday, stiff mid-level southwesterlies continue while high pressure continues to dominate at the surface. Short wave and associated cold front will be passing across the region at the beginning of the period.
In wake of a cold front, light rain has tapered off but plenty of low cloud cover remains. These clouds will be slow to clear overnight, thanks to the moist boundary layer conditions at the low levels.
Expect increasing cloud cover from northwest to southeast as a cold front enters Southeast Oklahoma late in the period. Under mostly clear skies, temperatures tonight to radiate down to the lower to middle 40s areawide. Afternoon high temperatures on Thursday to climb into the lower to middle 70s. West to southwest flow aloft to advect mid to upper-level clouds across the region on Thursday night allowing for overnight low temperatures to be slightly warmer in the lower 50s.
/issued 1101 PM CST Wed Nov 11 2020/ Clear skies and a much cooler night ahead in the wake of our latest frontal passage. The bulk of this forecast period should see VFR conditions and light winds as high pressure takes command of our area weather. A cold front is stretching from the Lower Atchafalaya River Basin northeast across the Appalachians and into eastern Great Lakes. High pressure is building east across the mid Mississippi Valley. As the cold front departs the area a drier and slightly cooler air mass will filter in.
Light snow should continue through the night in the mountains but it is still too dry at the lower levels in the plains for precipitation. Watching an upper level trof which is over the Northern Rockies this afternoon, as this system will quickly move across Colorado tonight and early Thursday. Expect westerly winds to increase over the mountains Thursday morning as the trof passes along with increasing subsident flow. Expect temperatures will be a bit cooler Thursday afternoon behind the trof and breezy conditions on the plains, especially over northern border sections.
A cold front has now passed through the ArkLaMiss tonight dropping low temps into the mid 40s across the Delta region and low to mid 50s elsewhere. The front will exit the region this evening, but in its wake, some non-trivial amount of moisture will linger in the low levels particularly across south and east portions of the area.
A cold front will move across the area this evening.
1201 AM EST Thu Nov 12 2020 Back edge of a mid-level cloud deck is very close to I-65, but difficult to see in IR imagery because the lower/mid-40s sfc temps under the clear skies are too close to the +4-5C cloud-layer temps noted in the ILN and OHX soundings at 0Z. High pressure traveling from Illinois to Ohio will supply us with cool, dry air on north breezes of 5-10mph tonight. Lows tonight will be in the 30s where skies clear, and in the low-mid 40s where clouds hang on. Tomorrow looks great as that high proceeds to upstate New York but continues to control our weather as it ridges southwestward into the Ohio Valley.
1034 PM MST Wed Nov 11 2020 One minor ripple in the broader upper level trough over the region is crossing northwest CO at this time.
1250 AM EST Thu Nov 12 2020 A cold front will push off to the southeast of the CWA overnight. High pressure building into the Ohio Valley will bring cooler and drier weather to the region for late in the week.
228 AM CST Thu Nov 12 2020 Warmer temperatures on tap for today as the southern plains remains under a quasi-zonal setup with above-normal 850mb temps thanks to persistent south/southwest flow.
High pres ridging southward acrs the region will provide N-NE winds 5-10 KT today, bcmg lt/vrbl tonight. /issued 316 AM CST Thu Nov 12 2020/ High pressure ridging down from the north will bring a modified dry continental airmass into the region for the next couple of days that will provide cooler night time temperatures.
244 AM MST Thu Nov 12 2020 Current surface map places cold front across northern Nebraska.
The models show a short wave ridge of high pressure will move across the region this afternoon through tonight. The airmass will become increasingly dry and stable after 12z, with high pressure at the surface and aloft. Across the northeast plains, a weak cold front will push into the Denver area by late this morning. High temperatures will be slightly cooler than yesterday, in the low to mid 40s. In Denver, the wind will be lighter and more variable as a Longmont anticyclone is expected to develop. A short wave trough embedded in the strong zonal flow will move onto the west coast Friday.
609 AM CST Thu Nov 12 2020 The entire seven day forecast is completely dry with this essentially zonal progressive pattern with relatively low moisture available, save for the chance of flurries that have been thrown in for our north/east today with the pass of an upper level trough and associated surface cold front. Synoptic lift abruptly ends this afternoon as the trough progresses east and any flurries should be out of here by sunset.
431 AM CST Thu Nov 12 2020 Today: This morning the synoptic pattern consists of a deepening trough axis over the northern Plains & lee side of the Rockies while mostly mean zonal flow exists across the southern half of the CONUS. There is also some lower clouds & fog in the Highway 45/Interstate 59 corridors, but this will lift by mid-morning. For forecast elements, expect temperatures to be cooler than the past few days but slightly above normal, only a few degrees above in the Highway 82 corridor to nearly 5+ degrees over the southern half of the region. Tonight: As remnants of Eta move off the Atlantic seaboard & trough axis swing into the Great Lakes, another cold front will move off to our northwest into the Mid-South & Great Lakes.
A cold front will continue pushing southeast through the Plains in the wake of the wave. Warmer air aloft quickly spreads east over the area with H85 near 10C across western NE by afternoon. At the surface a leeward trough will develop from near Rapid City down through Denver. The pressure gradient will tighten east of this trough with gusty south winds. Otherwise much warmer with highs ranging from the upper 40s to mid 50s (warmest across western NE). Warmer air aloft quickly spreads east over the area with H85 near 10C across western NE by afternoon. At the surface a leeward trough will develop from near Rapid City down through Denver. The pressure gradient will tighten east of this trough with gusty south winds. Otherwise much warmer with highs ranging from the upper 40s to mid 50s (warmest across western NE).
Any patchy fog will lift shortly after daybreak and then we will continue to see quiet conditions for Thursday as short wave ridging pushes to the east. Some high clouds associated with a short wave trough pushing into the PacNW will move over the area throughout the day. Our weather will become more active on Friday as a trough digs out of the Gulf of Alaska into the PacNW. Widespread precip is expected for the afternoon and evening as the cold front moves through the area. Breezy southerly winds can also be expected on Friday especially over the higher elevations.
Conditions dry out tonight as a weak cold front pushes across the central FL peninsula into early Friday morning.
Scattered to broken mid level clouds are forecast to spread across the CWA today ahead of a cold front expected to move into Northeast Oklahoma late this afternoon and exit West Central Arkansas late this evening. scattered to broken mid clouds along with the high clouds will remain possible behind the front tonight. /Issued 328 AM CST Thu Nov 12 2020/ Temperatures have fallen into the lower to mid 30s in some locations across eastern Oklahoma and northwest Arkansas early this morning with some patchy frost possible. Should see decent warm up this afternoon ahead of cold front that will move into northeast Oklahoma by late afternoon. Another cold start expected Friday morning behind front with a few locations falling to around freezing across far northeast Oklahoma and northwest Arkansas.
Elevated water levels will still be possible through the high tide cycle this afternoon, so a Coastal Flood Advisory remains in place for the west coast. High pressure builds in for the end of the week into the weekend, with no headlines expected.
A weak weather disturbance will move through on Friday with breezy winds and light snow possible over the high Sierra Nevada.
325 AM CST Thu Nov 12 2020 High pressure will be centered over the Great Lakes region today, and we will see continued dry and seasonable conditions. Models show a weak cold front pushing across the middle Mississippi and lower Ohio valleys late tonight into early Friday, then high pressure sliding across the region Friday afternoon into Friday evening. The front will pass through dry, then cooler air will follow, with high temperatures Friday dropping to several degrees below normal.
522 AM CST Thu Nov 12 2020 The main focus today will be a mid-level trough and associated cold front that will swing through this afternoon and evening. Upper level support from the trough and transient low to mid-level frontogenesis behind the surface front likely will focus a quick 1 to 3 hour window of precip this afternoon into early evening. Tonight, as surface ridging builds in and skies quickly clear following the trough passage, temps will fall into the teens to low 20s, so wet roads could refreeze. Surface ridging will pass east of the MS Valley on Friday with plenty of sunshine but below average highs in the 30s to low 40s.
Early this morning, high pressure was located to the south and east of the area. An approaching upper level wave will lead to an increase in clouds and bringing a cold front through the area this evening. Cold front will be chances for rain this evening. Discussion: Upper level wave will swing through the area this evening bringing with it a cold front.
A weak cold front will enter the Big Country this evening, pushing south to an San Angelo to Brownwood line around midnight.
Southerly winds should pick up a bit today with the highest speeds across the western counties. A weak cold front will approach the area tonight and as it does so, moisture should increase further ahead of the front. Cloud cover should stick around for most of the day on Friday and this should lead to highs being a few degrees cooler than today.
849 AM EST Thu Nov 12 2020 Showers end this morning as high pressure builds in, with gradually clearing skies.
613 AM CST Thu Nov 12 2020 Not quite as cold this morning compared to yesterday, with temperatures ranging from near freezing to as warm as 40 degrees within the more urban areas of the Kansas City metro. A cold front will approach the region from the northwest this afternoon, entering into far NW Missouri by around 2 pm, through the KC metro by around 6 pm, and completely through the remainder of the region by around 9 pm tonight.
423 AM EST Thu Nov 12 2020 Drier air will move into the region today as high pressure builds into the Great Lakes. High pressure will continue to provide dry weather and seasonal temperatures for the rest of the week.
328 AM CST Thu Nov 12 2020 Temperatures have fallen into the lower to mid 30s in some locations across eastern Oklahoma and northwest Arkansas early this morning with some patchy frost possible. Should see decent warm up this afternoon ahead of cold front that will move into northeast Oklahoma by late afternoon. Another cold start expected Friday morning behind front with a few locations falling to around freezing across far northeast Oklahoma and northwest Arkansas.
526 AM CST Thu Nov 12 2020 A cold front moves through with snow entering from the southwest this morning and spreading north and east today.
551 AM CST Thu Nov 12 2020 (Today and tonight) Surface cold front over western Kansas will move southeast into the area today as a mid-level trough moves from the northern and central Rockies to northern and central Plains.
423 AM CST Thu Nov 12 2020 Not quite as cold this morning compared to yesterday, with temperatures ranging from near freezing to as warm as 40 degrees within the more urban areas of the Kansas City metro. A cold front will approach the region from the northwest this afternoon, entering into far NW Missouri by around 2 pm, through the KC metro by around 6 pm, and completely through the remainder of the region by around 9 pm tonight.
Cold front lays across the northern half of the CWA this morning. so kept the High Wind Warning going this morning.
353 AM PST Thu Nov 12 2020 Below average temperatures will continue through Friday with today a little warmer and Friday a little cooler.
301 AM CST Thu Nov 12 2020 The main focus today will be a mid-level trough and associated cold front that will swing through this afternoon and evening. Upper level support from the trough and transient low to mid-level frontogenesis behind the surface front likely will focus a quick 1 to 3 hour window of precip this afternoon into early evening. Tonight, as surface ridging builds in and skies quickly clear following the trough passage, temps will fall into the teens to low 20s, so wet roads could refreeze. Surface ridging will pass east of the MS Valley on Friday with plenty of sunshine but below average highs in the 30s to low 40s.
* None High pressure continues building directly into Southeast Michigan this morning as we sit beneath the left entrance region of an upper jet streak over the eastern Great Lakes. As the surface anticyclone advances in south of M-59, conditions become more favorable for patchy fog and likely frost over the next few hours due to enhanced near-surface moisture from the recent rainfall. Additional clouds begin to fill in tonight as a midlevel trough swings into the Great Lakes from the northern Plains. The surface cold front pushes through Friday morning, delivering little more than mostly cloudy skies. The front ushers in a cooler air mass to the tune of about -7C at 850mb, which paired with lingering cloud cover through the day will keep temps well in the 40s on Friday.
351 AM CST Thu Nov 12 2020 A cold front moves through with snow entering from the southwest this morning and spreading north and east today.
640 AM EST Thu Nov 12 2020 Drier air will move into the region today as high pressure builds into the Great Lakes. High pressure will continue to provide dry weather and seasonal temperatures for the rest of the week.
338 AM MST Thu Nov 12 2020 Current surface map places cold front across northern Nebraska.
Surface analysis shows Eta along the Florida west coast near Cedar Key, with a large high pressure extending southwestward from the central Atlantic Ocean into the Bahamas. CAM guidance suggests that the best rain chances will remain along lingering low level convergence zones near or just east of the Upper Keys, and over the Gulf waters to the northwest of the Lower Keys. Weak troughing and ample low level moisture will linger over the Keys within light/variable flow tonight, with a ridge building at all levels across our region from Friday through the weekend.
Cold front that brought rain to Middle Tennessee yesterday has moved off to the east, with much cooler temperatures in the 40s to low 50s at present.
527 AM MST Thu Nov 12 2020 Went ahead and extended the High Wind Watch west to include Rawlins. Cold front lays across the northern half of the CWA this morning. so kept the High Wind Warning going this morning.
Today Through Friday Night 10Z mesoanalysis shows surface ridging over the state with calm conditions and clear skies area wide. Efficient radiational cooling has led to temps in the 30s and low 40s this morning with some locations in northern AR likely to see freezing temps near dawn. Surface ridging will slide northeast today and tonight as another mid-level wave traverses the central Plains. Another cold front will approach from the northwest this evening through tonight. Additional mid-level troughing will move towards the Rockies Friday night.
There is a slight chance for a light rain or snow shower tonight as a cold front arrives.
A cold front will move across the area this evening. Latest surface map shows an axis of high pressure extending just north of I-70 into central Indiana. Some high clouds have been streaming northeast into the area, and surface observations are starting to show some lower visibilities in light fog near the ridge axis. Otherwise, a fairly quiet day on tap as the high drifts east, with increasing southeast winds allowing temperatures to reach the mid 50s. Behind this system, high pressure quickly builds in again on Friday, with temperatures expected to only reach the 40s. Warm advection will be taking place Friday night as the high moves off to the east.
316 AM CST Thu Nov 12 2020 High pressure ridging down from the north will bring a modified dry continental airmass into the region for the next couple of days that will provide cooler night time temperatures.
Expect lows will be cooler tonight down into the low to mid 40s for most locations. A front will extend southward from this low and is forecast to pass through the forecast area late on Friday as high pressure passes to the north later Friday night. Highs on Friday will climb into the mid to upper 60s ahead of the frontal boundary with lows on Friday night in the low to mid 40s.
With the expected cloud cover, antecedent snow cover, and persistent CAA, highs today will generally be stuck below the freezing mark. Southerly flow becomes established for Friday as subtle mid level ridging moves overhead.
