Aikyam-Lab/Synoptic-Bench huggingface dataset:
In the mid and upper levels we have broad cyclonic flow across 2/3 of the lower 48 and more amplified ridging in the west. Given this think Thursday night will be the cooler night in the short term period, with some low to mid 20s possible especially in the deeper valleys in the east. Given this leaned a little cooler toward the 10th percentile of the NBM lows. We will see high clouds through the day and will see clearing skies through the evening for most, with some lower and mid level clouds possible right along the higher terrain in southeast Kentucky late tonight into Thursday.
At the moment, wind speeds are highest around the lower Keys, with some offshore stations indicating sustained winds near 15 knots and gusts near 20 knots. A weak trough is moving over the Florida Keys and adjacent waters today, resulting in an increase in cloudiness and shower coverage.
1125 AM MDT Wed Nov 3 2021 08z surface analysis had high over the Midwest with developing warm front from central MT into eastern CO. Water vapour had upper ridge over the northwest CONUS moving eastward toward the northern Plains. Today through Thursday, upper/thermal ridge builds into the northern plains.
1114 AM CDT Wed Nov 3 2021 (18Z TAFS) WV imagery shows the upper-level trough moving through West Texas and Southeast New Mexico. At the surface, the cold front has cleared all terminals, leaving them mired in IFR-LIFR conditions. Subsidence on the backside of the trough and a resumption of return flow should scatter skies to VFR most terminals by the end of the forecast period. A cold front that is currently south of I-10 will continue to move south today. Temperatures will fall into the 30's and 40's overnight with near freezing temperatures possible in northern Lea and Gaines counties.
119 PM MDT Wed Nov 3 2021 An upper ridge building into the area today will keep things quiet and continued dry.
1252 PM CDT Wed Nov 3 2021 Some upper to mid level clouds have begun to spread across the terminals ahead of a cold front set to move in today thru early tomorrow. The main point of concern would be possibly reduced VIS as showers directly impact the terminals then the lower CIGs into MVFR / IFR.
Low-level dry air is preventing most of this from reaching the surface, but still expect a few light showers and sprinkles south of I-40 this afternoon with the greatest chances in the southern Valley and southern Plateau as the virga eventually moistens the low-levels. The highest confidence of this occurring is at TYS. Garuckas Chattanooga Airport, TN 44 54 39 57 38 / 40 20 0 0 0 Knoxville McGhee Tyson Airport, TN 41 52 36 57 36 / 20 20 0 0 0 Oak Ridge, TN 39 52 35 56 36 / 20 10 0 0 0 Tri Cities Airport, TN 37 51 30 56 30 / 20 20 0 0 0 TN.
TFJ Upper ridge builds into the area today and remains over eastern Montana on Thursday. This will bring warmer temperatures into the region that will be around 15 degrees above normal on Thursday. Some areas will have a chance of rain showers with the cold front.
130 PM MDT Wed Nov 3 2021 19Z analysis showed an upper ridge building over the region from the west. The upper ridge will continue to build over the region tonight and on Thursday resulting in high temperatures on Thursday ranging from 5 to 10F warmer than average, with periods of mid/high clouds.
Moisture will be on a slow return to the area as an elongated upper trough encroaches on the area. By this afternoon and into tonight, the upper trough will be across the central plains and elongated to the northeast into the great lakes. By Thursday, the northern stream trough will split and eject over the great lakes leaving the southern stream wave in its dust over Louisiana. Highs tomorrow will range from the mid to upper 60s even low 70s along and southeast of I-65 and highs in the low 60s northwest of I-65.

Temperatures will be cool again tonight under mostly clear skies, with pre-dawn readings in the lower to middle 30s. Temperatures will be similar to today, with afternoon highs mainly in the lower 60s.
A big negative with this system will be the amount of dry air in the lower and mid levels of the atmosphere ahead of it.
This high pressure system will continue to dominate into the southeast and keep the CWA dry today. Highs today will be a few degrees warmer than yesterday which will result in maximum temperatures around normal.
1225 AM EST SAT DEC 5 2015 DRY HIGH PRESSURE WILL REMAIN ACROSS THE REGION THROUGH THE REST OF THE WEEK.
The low cloud and fog deck will have a good chance of expanding in central Washington through the night. It is unclear if the low clouds will become expansive enough to sustain itself as high clouds and increased mixing arrive with a frontal system early Saturday morning.

MORNING UPPER AIR CHARTS AND HI-RES SHORT RANGE MODELS SHOWED A WEAK MID LEVEL TROUGH WORKING THROUGH EASTERN NEBRASKA. BUT WAS DAMPENING AS IT ENCOUNTERED RIDGING TO THE EAST. MEANWHILE A MORE BROAD TROUGH WAS NOTED IN THE PACIFIC NORTHWEST MOVING INTO THE NORTHERN ROCKIES. A PIECE OF THIS TROUGH IS FORECAST TO BREAK AWAY AND TRACK INTO THE PLAINS SATURDAY AND SATURDAY NIGHT. IT APPEARS TEMPERATURES WILL BE ABOVE FREEZING DURING POTENTIAL RAIN EPISODES. SO NOT EXPECTING FREEZING RAIN. BUT ALSO IN THE LOW LEVELS WHERE SOUTHERLY FLOW MAINTAINS WEAK POSITIVE THETA-E ADVECTION. LOWS TONIGHT SHOULD HOLD IN THE LOW TO MID 30S BEFORE REBOUNDING ONLY INTO THE 40S SATURDAY AFTERNOON GIVEN CLOUD COVER. BUT WEAK RIDGING AND LIGHT SURFACE WINDS SUGGESTS 40S FOR HIGHS WILL BE ALL WE CAN MUSTER.
1221 AM EST SAT DEC 5 2015 LARGE AREA OF STRONG HIGH PRESSURE AND DRY AIR REMAINS LOCKED OVER THE ERN HALF OF THE US LATE THIS EVENING. WITH PRONOUNCED RIDGING EXTENDING THRU MICHIGAN. HIGH PRESSURE OVER FAR SW INDIANA WILL SHIFT EAST. MIGHT IT EXPAND BACK OUT AGAIN AFTER SUNSET? OUR LOW LEVEL FLOW WILL BACK MORE TO THE SSW AS THE HIGH MOVES EASTWARD. A LARGE AREA OF HIGH PRESSURE OVER THE NORTHEASTERN UNITED STATES WILL CONTINUE TO DOMINATE NORTHERN MICHIGAN'S WEATHER THROUGHOUT THIS FORECAST PERIOD.
Main short-term challenge is the extent and impact of potential freezing fog late tonight into Sat morning. Thinking is that we will see a repeat of the valley fog late tonight, but a few factors weigh against any expansion onto the higher/flatter terrain even though winds will be light and RH fields could support a "sunrise surprise. Therefore will limit the mention of fog to the valleys, but where it does occur freezing fog will be a concern.
HIGH PRESSURE WILL BUILD FROM THE MIDWEST INTO THE TN VALLEY REGION TONIGHT AND TOMORROW. HIGHS WILL BE COOLER THAN THE PAST FEW DAYS BUT STILL ABOVE NORMAL. COOLER.
135 PM EDT WED MAR 16 2016 WINDS WILL BE GUSTY TODAY DUE TO A STRONG PRESSURE GRADIENT FROM DEEP LOW PRESSURE OVER THE WESTERN GREAT LAKES. THIS LOW PRESSURE SYSTEM WILL REMAIN OVER THE REGION THROUGH THURSDAY.

229 PM MDT WED MAR 16 2016 WV IMAGERY AND RAP AFTERNOON ANALYSIS SHOWS NW FLOW EXTENDING FROM THE PACIFIC NORTHWEST INTO THE HIGH PLAINS WITH A CLOSED UPPER LOW CENTERED OVER THE WESTERN GREAT LAKES REGION. I KEPT SPRINKLE MENTION THROUGH THE EARLY EVENING AS THE LOSS OF DAYTIME HEATING/DECOUPLING OF THE LOWER ATMOSPHERE SHOULD HELP STABILIZE CONDITIONS AND PUT AN END TO ANY SHOWERS THAT FORM. LEE TROUGH STRENGTHENS AND SHIFTS EAST AS STRONGER UPPER TROUGH MOVES INTO THE CENTRAL ROCKIES AND A COLD FRONT APPROACHES THE REGION FROM THE NORTH. HOWEVER AS LEE TROUGH SHIFTS SOUTHEAST THE AIR MASS MAY NOT SEE AS MUCH OF A RECOVERY AHEAD OF THE FRONT. WE WILL PROBABLY SEE HIGHS IN THE 50S/LOW 60S (SIMILAR TO SLIGHTLY WARMER THAN TODAY).
358 PM CDT WED MAR 16 2016 ABOVE SEASONABLE TEMPS AGAIN TODAY WITH CURRENT OBS IN THE LOWER 70S. 10 DEGREES COOLER THAN THE RECORD SETTING TEMPS YESTERDAY. DRY AIR HAS ALSO FILTERED INTO THE REGION BEHIND THE COLD FRONT THAT MOVED THROUGH OVERNIGHT.

/ISSUED 401 PM CDT WED MAR 16 2016/ COLD FRONT WHICH USHERED IN THE SLIGHTLY COOLER AND MUCH DRIER AIR MASS HAS STALLED TO OUR SOUTH AND IS BEGINNING A SLOW RETREAT NWD THIS AFTERNOON.
1247 PM CDT WED MAR 16 2016 THE LOW PRESSURE SYSTEM RESPONSIBLE FOR THE STRONG AND GUSTY WESTERLY WINDS TODAY HAS MOVED FURTHER EAST. STRONGEST WINDS WILL DEFINITELY BE EAST OF I-35 BUT AS THE LOW PULLS OFF AND GRADIENT TAKES ON MORE OF A WESTERLY DIRECTION STRONGEST WINDS MAY EXTEND MORE TOWARDS FORT DODGE. THE UPPER LEVEL LOW WILL STALL OVER NORTHERN LAKE MICHIGAN THROUGH MUCH OF THURSDAY BEFORE BEGINNING TO SHIFT OFF TO THE EAST AS ANOTHER SYSTEM DROPS SOUTH FROM CANADA. THIS PROCESS WILL SWING A TROUGH SOUTH INTO IOWA AND BRING COLDER AIR INTO THE STATE.
HIGH PRESSURE IN THE CENTRAL PLAINS CONTINUES TO BUILD EASTWARD IN THE WAKE OF A RECENTLY DEPARTED COLD FRONT FROM EARLIER THIS MORNING, CURRENTLY SPRAWLING FROM THE GREAT LAKES DOWN THE SPINE OF THE APPALACHIANS, AND SWWRD INTO THE NWRN GOMEX. THIS SHOULD TRANSLATE TO RH VALUES FALLING INTO THE LOWER 20S AND UPPER TEENS LATER THIS AFTERNOON.
214 PM EDT WED MAR 16 2016 A COLD FRONT WITH LITTLE MOISTURE WILL CROSS THE AREA THIS AFTERNOON AND EVENING.
THE WEATHER WILL BE RATHER QUIET THROUGH THURSDAY AS AN UPPER RIDGE BUILDS OVER THE AREA. CURRENT VISIBLE IMAGE SHOWS CLOUD COVER GRADUALLY DECREASING AND THAT TREND WILL CONTINUE INTO TONIGHT AS THE THERMAL TROUGH DEVELOPS ALONG THE COAST AND OFFSHORE FLOW INCREASES. AS PREVIOUSLY MENTIONED, THE OFFSHORE FLOW WILL INCREASE AND SHOULD BE STRONG ENOUGH FOR A CHETCO EFFECT TO SET UP RESULTING IN MILDER TEMPERATURES TONIGHT AND WARMER TEMPERATURES THURSDAY AFTERNOON.

HOWEVER AS LEE TROUGH SHIFTS SOUTHEAST THE AIR MASS MAY NOT SEE AS MUCH OF A RECOVERY AHEAD OF THE FRONT. WE WILL PROBABLY SEE HIGHS IN THE 50S/LOW 60S (SIMILAR TO SLIGHTLY WARMER THAN TODAY).
A weak cold front will pass through southeastern NM and the Permian Basin of west Texas overnight before becoming quasi- stationary along I-20. However, MVFR, if not IFR, conditions could affect KMAF after 17/06Z ahead of a cold front. Will forego inclusion of the lower ceilings/ visibility this forecast since they will occur near the end of the forecast period, and may not occur at all if the front proves faster than the latest data suggests. /issued 434 AM CDT WED MAR 16 2016/ An upper trough is currently over the Northern Plains and Upper Midwest resulting in westerly flow over the CWA. Temperatures on Thursday will cool to near normal values as a cold front moves through the area during the day.
