Aikyam-Lab/Synoptic-Bench huggingface dataset:
355 AM MST Mon Dec 19 2016 Wide range of temps early this morning across the area, with coldest readings in the San Luis Valley and across the lower Arkansas Valley, where snow cover and fairly strong inversions have combined to drop readings well below zero. Air mass will continue to slowly moderate today as increased westerly flow brings warmer air aloft into the region, while surface arctic air gradually retreats farther to the east. Snow covered lower Arkansas River Valley from about Pueblo to Kansas will likely struggle to break the inversion once again, and temps around La Junta and Lamar may stay at or slightly below freezing. For the higher elevations, highs will be in the 20s and 30s.
Next up for discussion is snow in the mountains and a messy mix for the lower elevations. Looking at the latest soundings, while there is some potential for light freezing rain/sleet around Pocatello westward. The highest snow amounts will be in the Sawtooths were up to a foot (and perhaps a bit higher) is possible. For those areas, where we are looking to mix out, little accumulation of any snow/sleet/freezing rain to be minimal.
922 AM EST Mon Dec 19 2016 High pressure will dominate the region for the first half of the week.
909 AM EST Mon Dec 19 2016 Cold Arctic high pressure builds over the area today. A warm front will move north of the region Tuesday.
739 PM EDT Wed Oct 12 2016 A large area of high pressure will cover the eastern United States through tonight.
Thus made a minor adjustment to the hourly temperatures to show the lower temperatures. /issued 243 PM CDT WED OCT 12 2016/ Vigorous cold front had cleared the forecast area as of 19z. Isentropic lift will increase ahead of an upper level trough tonight.
722 PM EDT Wed Oct 12 2016 A cold front will pass through the commonwealth during the morning and midday hours on Thursday.
Otherwise, a cold front will slowly move south tonight and bring areas of MVFR conditions with showers and a few thunderstorms.
622 PM CDT WED OCT 12 2016 19z/2pm surface analysis shows cold front approaching the I-55 corridor. Once the front passes, skies will gradually clear from west to east overnight as a much cooler/drier airmass flows into the region. With strong high pressure firmly in control of the weather, sunny and cool conditions are expected on Thursday with highs only in the upper 50s and lower 60s. The affects of the chilly high pressure will linger on Thursday night, as mostly clear skies for a majority of the night help low temps dip into the lower 40s.
Surface analysis shows a cold front stretching from the Permian Basin towards eastern Oklahoma and this boundary will approach the Southeast Texas terminals tonight, stalling near College Station/ Huntsville 12-15Z Thursday.
Will keep the headline as is, with widespread frost expected as temps approach the or fall below the freezing mark. /Thursday through Wednesday/ Still expected to be cooler and dry into Thursday with little overall changes made through the mid/long range as well. High pressure shoves to the east into Thursday night with return flow setting up aloft bringing h85 temps back into the low teens Celsius. Stronger trough to slide along south central Canada into the weekend with southerly flow and waa picking up ahead of that wave.
912 PM MDT Wed Oct 12 2016 Upper ridge in place over the northern Rockies was providing a clear sky over most of Montana. Dry weather can be expected through Thursday as a low amplitude ridge sets up over the region continuing a warming trend.
Tonight and Thursday Cold front moving across the region early this afternoon and should continue to move away from the area tonight.
A subtle and weak upper level trough will also approach the mid state region during the overnight hours tonight. Model solutions start to diverge here, with the latest GFS and NAM/DGEX solutions ushering another upper level distrubance across the mid state at least during the first half of Sun, with the latest ECMWF solution being more progressive and developing upper level ridging across our area sooner on Sun than the above mentioned other solutions.
Much of the region is expected to see patchy frost overnight, with far northwest Missouri flirting with freezing temperatures. A weak open wave and returning moisture on the western edge of high pressure may provide a slight chance of precipitation south of Interstate 70 Thursday night.
As of mid afternoon, a cold front was analyzed from near Madison, Wisconsin southwest through central Missouri. Visible satellite showed mostly sunny skies prevailed across the lower Ohio Valley with broad southwest flow helping to take temperatures up into the middle to upper 70s. This cold front will race into the region later this evening and overnight, bringing with it a chance of showers and perhaps a thunderstorm. The highest chances /50-60 percent/ will be found north of the Ohio River, while central Kentucky will have lower chances /30-50 percent/ mainly midnight to sunrise Thursday. A quick shot of cool Canadian high pressure will bring seasonable temperatures and north winds to the area Thursday. A cool night is in store as lows fall into the low 40s across the Bluegrass to around 50 for south- central Kentucky.
1045 PM EDT Wed Oct 12 2016 Currently - A large high pressure system extends along the Atlantic and the Gulf coasts, resulting in moderate to fresh northeast breezes across the Florida Keys and surrounding waters. Satellite imagery corroborates model output in depicting a subtle lower level trough extending across the northern Bahamas and nosing into South Florida. The combination of more headroom under the solid inversion and the subtle trough has been sufficient to generate isolated to scattered weak shower activity, along with a number of outflow boundaries. Short Term Update - Surface ridging to our north will maintain moderate to fresh northeast breezes across the Florida Keys area. A ridge extending along the Atlantic and Gulf coast states is producing moderate to fresh northeast breezes across Florida Keys waters.
Patchy fog will be possible south of the Highway 84 corridor early Thursday morning as low-level moisture edges northward. A cold front was approaching the region from the northwest. Mid afternoon temperatures were in the lower to middle 80s. Lows for tonight will range from the upper 40s east to the lower 60s northwest. Opted to go with the cooler Canadian guidance for our eastern counties.
The front will switch winds to the northwest to northeast overnight, as cooler air filters into AR. Otherwise, a cold front will slowly move south tonight and bring areas of MVFR conditions with showers and a few thunderstorms.
752 PM EDT Wed Oct 12 2016 High clouds are moving in from the west out ahead of the approaching cold front. This is allowing for a quick drop off in the cooler eastern valleys. As such, have dropped the low temperatures a couple of degrees, with some places likely making it into the mid 40s, as clouds will remain thin overhead until later tonight. Will keep isolated to scattered POPs in the forecast, but did delay the arrival a touch more based on the latest trends in the higher resolution model guidance. High pressure will control our weather through the evening as a cold front approaches from the west. Light south winds will keep open valleys and ridges much warmer and even temperatures in the deeper valleys will likely rise back into the 50s after midnight as clouds come in.
A warm front will move through the northern part of the valley during the day on Thursday and may bring some precipitation to the far northern part of the valley and surrounding foothills and mountains.
High pressure at the surface will remain stretched from the Atlantic coast into the gulf states Thursday.
928 PM EDT Wed Oct 12 2016 A cold front will cross the area by Thursday morning. Shower chances will increase after midnight as the upper trough over the northern Great Lakes swings a cold front toward the region. Front will continue to make progress across the upper Ohio Valley early, followed quickly by building high pressure. With northwest flow and moisture lingering in the high terrain, have kept chance PoPs in the forecast through Thursday afternoon.
Temperatures will respond accordingly as highs climb into the mid 50s over southwestern MN/northwestern IA, to the lower to mid 60s through the James River Valley and south central SD.
Reduced the coverage of freezing fog as a result. TFJ Upper ridging will be the dominant player tonight into Thursday, making for mostly clear skies, light winds and warming temps.
Chances for showers will move in with a cold front from the northwest during the TAF period, and mainly impact KCKV.
1033 PM MDT Wed Oct 12 2016 A weak trough moving ashore over southern California continued to spread cirrus, mainly of the thin mostly transparent variety, over the region this afternoon.
