Aikyam-Lab/Synoptic-Bench huggingface dataset:
247 PM CST Sun Nov 6 2016 Quiet weather will prevail across central and southeast Illinois through Monday, as a sprawling ridge of high pressure extending from Quebec to the Gulf Coast continues to dominate the weather. Despite weak southeasterly return flow on the back side of the high, excellent radiational cooling of the dry airmass will allow low temperatures tonight to drop into the lower 40s. a broad upper trough over the southern Rockies will progress slowly into the southern Plains and help draw moisture northward ahead of the approaching northern features.
1103 AM MST Sun Nov 6 2016 The area of low pressure has weakened considerably and has now become an open wave or trough with the axis having moved over the Rocky Mountains. Since the system was barotropic as it moved overhead, little cold air advection took place so temperatures will be somewhat warmer than yesterday thanks to less cloud cover or precipitation but no major hot or cold swings are expected. Height rises overnight indicate high pressure building in allowing Monday to be a sunny and warm day.
324 PM EST Sun Nov 6 2016 High pressure will remain in control of the weather through the middle of the week.
305 PM CST Sun Nov 6 2016 Water vapor shows a distinct vort lobe rotating across southeast NM which will serve to reload the larger trough axis still atop the South Plains. With a weak cold front and north winds spreading south from the Panhandle by mid-late Mon morning, fog will erode leaving a shallow stratus layer that could linger longer than models indicate-particularly off the Caprock. PoPs on Mon were scaled back to focus mention in our eastern zones nearest the upper trough axis and more favorable ascent. Slow moving trough axis should be just east of the area Monday evening. As the main trough moves into the Ohio Valley, a trailing trough will persist back into Central TX into Chihuahua. A positively tilted ridge/block will set up out west.
A drier variety cold front dropping southward through the eastern plains tonight will result in downslope flow out of the north and northwest, inhibiting the return of low clouds and fog there. The upper low which brought widespread showers and thunderstorms to much of the area the past couple of days will move off to the east today. A weak backdoor cold front remain on track Monday, brining slightly cooler air and a chance for isolated showers or storms to the east slopes of the Sangre de Cristo mountains. Strong high pressure over the Great Basin will keep the storm track well north of the state through the week.
An approaching cold front will help lift ceilings to MVFR by mid- morning, and also shift winds around out of the north at about 10 to 15kts. /Issued 420 AM CST Sun Nov 6 2016/ Four Corners closed upper low is starting to open up now as it shifts eastward over the CO Rockies per water vapor imagery. Temperatures will remain fairly steady in the high 50s and low 60s with cloud cover in place through the day. Some of the high res models are trying to initiate some isolated thunderstorms after the main shield of precip moves through during the afternoon across the western half of CWA. As the upstream side of the upper trough shifts through the Plains Monday an accompanying surface cold front will shift southward through the Panhandles. Slightly cooler temperatures can also be expected.
1155 AM CST Sun Nov 6 2016 Sprawling ridge of high pressure extending from Quebec to the Gulf Coast will dominate the weather across central Illinois today, providing light winds and plenty of sunshine. The center of the high will reside to the east of Illinois, allowing for continued south-southwest winds into the area. Overnight lows will dip back into the lower 40s, with light and variable winds. This wave will start to sharpen early this week, as a broad upper low/wave currently over Colorado tracks into the Plains on Monday.
942 AM MST Sun Nov 6 2016 Dry north to northwest flow aloft will bring mostly clear skies and unseasonably warmer temperatures to the region this week.
After this initial wet period, the upper trough that's helped fuel the rain will split, with part drawn along the northern jet stream to the east, while some vorticity gets drawn back to our west - depending on the model, over Arizona, New Mexico, Northwest Mexico, or far West Texas.
300 PM EST Sun Nov 6 2016 More quiet and dry weather is in store for eastern Kentucky tonight through tomorrow night, as a ridge of high pressure remains entrenched across the region. Another chilly night is expected tonight, as clear skies and near calm winds lead to large ridge and valley temperature differences.
137 PM MST Sun Nov 6 2016 Water vapor shows upper trof pushing through the nrn Rockies with srn stream trof moving out of the cntrl/srn Rockies. A few -shra lifting newd through Neb associated with srn stream trof. Near freezing temps expected most areas Monday night with light winds and clear skies. Western CONUS upper ridge rebuilds over the northern plains by midweek, with dry conditions and very mild temperatures continuing.
1054 AM CST Sun Nov 6 2016 Another quiet morning is underway, with temperatures settling into the low to mid 40s for most, and mid to upper 30s across the far eastern Ozarks.
Clear skies tomorrow morning should give way to some cirrus moving in from the southwest as the upper ridge inches east. Forecast concerns include two cold fronts.
333 PM CST Sun Nov 6 2016 An upper level trough at 500 mb currently over Colorado will continue moving northward tonight, bringing an abnormally moist airmass into the region. Have nudged pops up some, but only into the lower chance range. Drier and cooler air will filter into the region from the northwest on Monday.
215 PM CST Sun Nov 6 2016 Upper impulse is currently situated over southeast CO/northeast NM and is continuing to lift out into the high Plains. This will result in surface ridging over the southern Plains keeping a dry forecast in place through Fri. There are no concerns until late this eve when MVFR cigs ~2,500ft spread slowly E into KGBD & KRSL as a N/S oriented lwr-deck trof likewise moves slowly E into Cntrl KS.
Upper wave has lifted into northern Idaho this morning while a ridge builds in from the west coast. The lower Snake Plain and central Idaho mountains could see sprinkles through early afternoon, but little chance of any measurable precipitation. A weak upper level system and accompanying cold front are working their way through the CWA this morning. Showers will end this afternoon, and tonight and tomorrow will be dry as ridging moves in aloft.
245 PM EST Sun Nov 6 2016 Models show good agreement with strong high pressure remaining anchored over deep south and maintaining dry conditions through the short term and beyond.
1225 PM EST Sun Nov 6 2016 High pressure will persist across the region through much of the week.
Temperatures will remain well above normal tonight as a prevailing southeasterly upslope flow does little to modify the air mass across the high plains. As the upper level trough moves into the Mississippi Valley Monday night the GFS and ECMWF both continue to support ridging aloft starting to move out into the northern plains as an upper level low develops and moves southwest across the southern Plains.
342 PM CST Sun Nov 6 2016 Upper level trough over NM and W TX should will continue to progress slowly eastward over the next several days.
109 PM MST Sun Nov 6 2016 Water vapor imagery shows the upper low moving across Colorado today with some moisture associated with this system pushing up into the Nebraska panhandle. As anticipated, westerly winds across southeast Wyoming have become breezy today as the leeside pressure trough deepens, with gusts 35 to 45 mph observed in some of the wind prone areas along and west of I-25. The weak cold front will move across the region this evening and into the early overnight time frame. High pressure will build over the area on Monday bringing cooler temperatures and less wind.
Otherwise, with a mild airmass in place, temperatures are on track to climb into the low to mid 70s this afternoon.
High pressure will bring dry and warm weather through the next seven days. Ridging continues to build over the Interior West through late in the workweek with little to no chance of precipitation state-wide.
The high resolution models are trending towards far eastern LaMoure and Dickey counties as the most likely location for any precipitation to develop, which occurs is between 00z-06z Monday. Currently, subtle embedded mid/upper level low moving north across eastern Montana, while a larger upper low over the Desert Southwest morphs into an open wave and moves east-northeast across the central Rockies. Water vapor imagery loop clearly shows these features rotating around the larger open wave and moving north across the high plains. Increasing boundary layer moisture today along to east of Highway 83 with dewpoint temperatures climbing into the low/mid 50sF. Pacific northwest short wave trough pushes into the Northern Plains early Monday shifting a cold front through the region. This will result in cooler temperatures for Monday and some breezy northwest winds.
250 PM EST Sun Nov 6 2016 Broad upper ridging to narrow a bit Monday as upper trough moves through the Plains states with upper cirrus clouds moving overhead.
At the surface, a ridge of high pressure centered over the Mid-Atlantic states is bringing mostly sunny skies to areas north of I-40. This trof will phase with northern branch energy dropping southeast from southern Canada on Monday.
111 PM EST Sun Nov 6 2016 A pesky upper trough over the Northeast and Canadian maritimes will continue to provide the North Country with cloudy skies, before high pressure building over the Great Lakes and Ohio Valley begins to shift east allowing some sunshine to develop this afternoon.
1023 AM CST Sun Nov 6 2016 Sprawling ridge of high pressure extending from Quebec to the Gulf Coast will dominate the weather across central Illinois today, providing light winds and plenty of sunshine. The center of the high will reside to the east of Illinois, allowing for continued south-southwest winds into the area. Overnight lows will dip back into the lower 40s, with light and variable winds. This wave will start to sharpen early this week, as a broad upper low/wave currently over Colorado tracks into the Plains on Monday.
Fog has all but dissipated across the far eastern plains and mountains, except for the high passes. A weakening upper level low over northwest Colorado will continue to lift northeast today. Due to more cloud cover today, expect slightly cooler temperatures over the eastern plains. As the upper level low continues to lift northeast, moisture is expected to slowly decrease through the afternoon and evening. A strong upper level ridge/trough blocking pattern across the continental US will likely result in few day-to-day changes on our weather.
The ridge will slowly slide east overnight into Monday. There will actually be cooler air just above the surface that flows over Wisconsin tomorrow, so expect high temperatures to be lower than they were today, in the lower to mid 60s.
254 PM CST Sun Nov 6 2016 High pressure continues to dominate the mid state, with above average temperatures to linger through the work week.
Satellite trends indicate progressive subsidence and clearing in the wake of a lead trough responsible for the MCS now entering north TX.
