Aikyam-Lab/Synoptic-Bench huggingface dataset:
142 AM PDT Wed Oct 16 2024 * The first storm of the week arrives today and ushers in cooler temperatures as well as our initial round of showers, including snow showers in the highest terrain.
(Today) Chilly start to the morning with a few sites falling near or below freezing, and a widespread light freeze probable across northeast OK and northwest AR this morning.
420 AM EDT Wed Oct 16 2024 Canadian high pressure will build southward towards the Appalachian Mountains today.
449 AM EDT Wed Oct 16 2024 * An upper level trough axis over the state this morning will move to the Mid Atlantic Coast this afternoon.
1244 AM EDT Wed Oct 16 2024 Strong high pressure builds southward from Canada across the Midwest to the mid-Mississippi Valley into Wednesday.
- A cold front will bring breezy conditions this morning and cooler temperatures for the rest of the week. (This evening through Wednesday) This afternoon, a broad upper-level trough was digging southward over the southern US. This feature was pushing a surface cold front into the southern Plains. High temperatures should be in the upper 60s to mid 70s, which is about 20 degrees cooler than what we have seen the past several days and should be a welcome change.
208 AM EDT Wed Oct 16 2024 Canadian high pressure will build southward towards the Appalachian Mountains by Wednesday.
1210 AM CDT Wed Oct 16 2024 (Tonight) A secondary cold front is moving south through the region, bringing even colder and drier conditions to the area as a positively tilted upper trough digs south into the Tennessee Valley.
- Near to sub-freezing temperatures likely later tonight into Wednesday morning, Freeze Warning remains in effect.
A longwave trough will continue to dig southeast into and through the southeast United States during the period. While this happens, high pressure at the surface will continue to settle south southeast into the Mid-South region and Tennessee Valley. This will result in continued quiet weather across the forecast area today, as cold advection continues to filter in a noticeably cooler drier airmass while highs struggle to climb out of the 60s.
Strong mid/upper ridge develops over the Great Lakes and East Coast with a pair of nearly-stationary upper lows across the southwest CONUS and Atlantic keeping the pattern stagnant. The next (very low) chance of rain arrives on Tue as ejecting upper low sends a weak cold front through the area. A large upper-level trough is sinking south through the Tennessee River Valley.
By that time, freezing conditions are expected near/west of Highway 51 where a Freeze Warning remains in effect, with low-mid 30s temps fostering frost further east where there's a Frost Advisory (both headlines through 8am). There's some concern about localized freezing conditions within the Frost Advisory as drier air advects south- southeastward into southeast Illinois the next several hours, but preparedness actions are pretty similar for both conditions as either will harm/kill tender vegetation.
141 AM EDT Wed Oct 16 2024 Showery, November-like weather will continue overnight as a trough moves south through the region, followed by lake effect showers through Wednesday morning.
An elongated upper level trough is digging into the southeastern US today, pulling a strong surface front into the Florida Peninsula. This will favor cold air advection, pulling noticeably cooler and drier air into the region.
(Today and tonight) Following yesterday evening's FROPA, weak ridging builds in aloft today with the next wave pushing into the northern Pacific. The widespread coldest temperatures in the forecast are expected today with highs in the lower to mid 60s across the forecast area.
Temperatures below freezing are expected across the area.
Temperatures warm above freezing region wide by 9AM.
- Temperatures will be much cooler today with breezy conditions this morning. (Today and tonight) In the wake of the cold frontal passage yesterday evening and last night, much cooler air was moving into our area early this morning and accompanied by gusty northeast winds. After highs in the 90-95 degree range yesterday, temperatures will be much cooler today with mostly sunny skies. This to occur as the high pressure system over the Midwest moves east into the Ohio and Tennessee River Valleys.
117 AM EDT Wed Oct 16 2024 A strong upper level trough of low pressure will cross the Ohio Valley tonight, with a deep and persistent northerly flow behind it.
136 AM EDT Wed Oct 16 2024 * An upper level trough will pivot through Pennsylvania through Wednesday, bringing additional scattered rain showers and perhaps a few snowflakes at higher elevations.
An area of moisture/cloud cover wrapping around the cyclone flow of the upper trough will keep sky cloudy/mostly cloudy over much of the area, except for the southern Plateau and parts of southeast Tennessee. For tonight, building ridge of high pressure and clearing sky over much of the region will allow temperatures to drop at or near freezing over the northern half of the area.
A cold front will bring showers to the region on Wednesday and around 20 degrees of cooling compared today.
855 PM PDT Tue Oct 15 2024 The arrival of a cold front tonight will produce widespread rain for the Inland Northwest.
- Warmer temperatures arrive after today with lows in the 50s and highs in the 70s, generally 10 to 15 degrees above normal for mid- October.
619 AM EDT Wed Oct 16 2024 * An upper level trough axis over the state this morning will move to the Mid Atlantic Coast this afternoon.
The resulting light winds and continued clear skies will allow for another night of efficient radiational cooling to near and below freezing, with widespread frost expected outside of Chicago and away from the immediate lakeshore through early Thursday morning. A return to southerly low level flow and warm advection commences as upper ridging builds east into the region overnight into Thursday.
Several locations outside of the warmer "concrete jungle" locations reported temperatures below 36 degrees and some patchy frost. This will open the door for several spots to be near freezing and a few low-lying areas should see upper 20s.
915 AM CDT Wed Oct 16 2024 - Lows tonight into Thursday morning will be in the low to mid 30s.
- Next cold front moves in tonight. Precipitation possible Thursday into Thursday night, with areas south of highway 200 getting the highest amounts. WEATHER PATTERN OVERVIEW: Upper ridge will move across the region, with a trough approaching the west coast. As the trough dives south at the end of the week, a closed low develops over the Great Basin. As the trough approaches and the ridge moves east today, a weak lee low pressure develops over central Montana. The front will move east overnight, with much cooler temperatures for Thursday.
- Gusty northeast winds and much cooler temperatures are expected today. Enjoy the fall weather today! Barnes Previous Discussion: /Wednesday and Thursday/ A strong cold front continues to move through the region, with gusty northeast winds filtering in behind the front. Locations along the Red River have already fallen into the 50s, and continued cold air advection should allow temperatures to bottom out in the lower 40s to mid 50s across the region by daybreak. A few spots in eastern Central Texas along low- lying river valleys could see temperatures fall into the mid 30s with a low (20-30%) of freezing temperatures in a handful of locations. High temperatures are expected to reach into the low to mid 70s Thursday afternoon. Despite the cooler temperatures, low humidity, unfiltered sunshine, and cured fuels will keep the wildfire threat elevated today and Thursday.
559 AM CDT Wed Oct 16 2024 (Today through Thursday afternoon) The long-awaited cold front is making steady progress south through the region early this morning. A strong and gusty northeast wind is ushering in cooler temperatures behind the front. With that said, the windy conditions should make it feel significantly cooler than the observed temperature. Much cooler weather is expected for the afternoon with widespread mid 60s to low 70s. Modest ridging takes back over tonight into tomorrow as large- scale troughing continues to develop to the west.
Temperatures below freezing are expected across the area. - Lows tonight into Thursday morning will be in the low to mid 30s.
646 AM CDT Wed Oct 16 2024 (Today through Thursday Night) The short term fcst remains settled in the wake of a strong cdfrnt fm Tues aftn, w/ seasonably cooler condns persisting, bringing frost potential and near-freezing condns to portions of the FA this mrng and again on Wed night/Thurs mrng. , readings in the low to mid 30s. Frost and potentially near or freezing condns are expected over much of N/Wrn to Nrn AR thru 12Z this mrng. In the wake of this frnt, aftn condns today wl feel much more like fall around the FA, w/ high temps only tipping the low to mid 60s in the Natural State. Some isolated instances of freezing may be seen as well, but widespread freezing condns are not expected.
Temperatures have not dropped to at or below freezing for any appreciable area and/or time frame, and there will not be any counties removed from the frost/freeze program. However, many sheltered locations (like Lancaster, OH airport) are observing below freezing temperatures. Cloud cover begins to decrease during the evening hours, and the winds will follow, setting the stage for another round of frost/freezing temperatures. Given the higher chance for lighter winds, and the high pressure building in from the south, more widespread temperature values between 30 to 33 degrees are expected. The high pressure continues to build over the region during the afternoon, supporting light and variable winds. Abundant sunshine will modify the cooler air mass, resulting in high temperatures around the 60 degree mark.
600 AM CDT Wed Oct 16 2024 (Today and tonight) Following yesterday evening's FROPA, weak ridging builds in aloft today with the next wave pushing into the northern Pacific. The widespread coldest temperatures in the forecast are expected today with highs in the lower to mid 60s across the forecast area.
- Cooler and more unsettled late in the week, with a good chance of rain and possible snow across portions of northeast WY and the Black Hills. Upper ridging continues across the northern Plains, with the main axis now sliding into the eastern Dakotas to MN. An upper trough is moving into the Pac NW. A cold front will cross the northern half the CWA Thursday morning, then stall in the afternoon. Models still show the Pac NW upper trough pushing into the western third of the CWA Thursday night.
(Now through Thursday night) A much cooler and drier airmass continue to move into the region this morning as strong high builds southward. High temps today will only climb into the low 60s across far northern areas to upper 60s to near 70 along the coast.
Cold front is moving through the area with drier air spreading south. Boundary will continue to move south with breezy north to northeast winds setting up behind it as high pressure builds in from the north. An elongated upper level trough is digging into the southeastern US today, pulling a strong surface front into the Florida Peninsula. This will favor cold air advection, pulling noticeably cooler and drier air into the region.
A longwave trough will continue to dig southeast into and through the southeast United States during the period. While this happens, high pressure at the surface will continue to settle south southeast into the Mid-South region and Tennessee Valley. This will result in continued quiet weather across the forecast area today, as cold advection continues to filter in a noticeably cooler drier airmass while highs struggle to climb out of the 60s. Look for lows tonight to range from the mid 30s north to the lower 40s south.
(Today through Thursday) A broad upper trough over the eastern U. will shift off the Atlantic Seaboard by Thursday as a narrow upper ridge shifts E from the Great Plains to the OH Valley. At the surface, sprawling high pressure will move from the Central Plains to the E U. After a cool start, high temperatures today will range from the lower 50s across the NE mountains to the mid 60s across the SE half of the County Warning Area. The coldest night of the fall thus far is expected tonight, with low temperatures ranging from near 30 in the NE mountains to the lower 40s across the extreme S. Temperatures will warm a bit for Thursday as the upper trough departs and the upper ridge approaches.
Strong mid/upper ridge develops over the Great Lakes and East Coast with a pair of nearly-stationary upper lows across the southwest CONUS and Atlantic keeping the pattern stagnant. The next (very low) chance of rain arrives on Tue as ejecting upper low sends a weak cold front through the area.
The ridge center was located over E NE. This will help our temperatures drop a couple of degrees cooler tonight.
High temperatures will once again be cooler than normal for mid- October with low/mid 40s at higher elevations and upper 40s to low 50s in valley areas.
518 AM CDT Wed Oct 16 2024 (Today) Chilly start to the morning with a few sites falling near or below freezing, and a widespread light freeze probable across northeast OK and northwest AR this morning.

631 AM CDT Wed Oct 16 2024 - Temperatures will be much cooler today with breezy conditions this morning. (Today and tonight) In the wake of the cold frontal passage yesterday evening and last night, much cooler air was moving into our area early this morning and accompanied by gusty northeast winds. After highs in the 90-95 degree range yesterday, temperatures will be much cooler today with mostly sunny skies. This to occur as the high pressure system over the Midwest moves east into the Ohio and Tennessee River Valleys.
Mid- level Water Vapor shows the trough previously over the Carolina Coast that was supporting light and easterly winds started to deteriorate. Although these showers will be fast moving and shallow because of the higher amount of showers possible.
627 AM CDT Wed Oct 16 2024 (Today through Thursday Night) A relief from the heat, at last! A cold front is moving across SE TX and is currently extending near Bay City/Matagorda Bay per radar and satellite imagery. Surface observations in the past couple of hours have reported gusts from 20 to 35 mph with the higher gusts along the barrier islands/nearshore waters. This front will also leave us with cooler conditions. Temperatures will be 20+ degrees cooler than yesterday! Strong cold air advection will keep today's highs in the 70s to near 80 degrees. Light winds, mostly clear skies and surface dewpoints mainly in the 30s degF will result in temperatures into the upper 30s to mid 50s inland and into the low 60s along the coast. Cooler readings expected across the Brazos Valley and Piney Woods area.
Temps will fall to lows near 40F tonight over the northern tier but will be about 15 degrees warmer on the south shore due to the lakes as well.
This will open the door for several spots to be near freezing and a few low-lying areas should see upper 20s.
603 AM CDT Wed Oct 16 2024 (Today) The upper trough that brought mainly clouds and gusty winds to our area yesterday will continue to move towards the eastern seaboard today. Meanwhile, an upper ridge will build over the Southeastern states right behind it. After temperatures in the upper 30s to lower 40s this morning, highs will struggle to warm past the mid 50s to lower 60s today (cooler in the east).
(Today through Thursday Night) A relief from the heat, at last! A cold front is moving across SE TX and is currently extending near Bay City/Matagorda Bay per radar and satellite imagery. Surface observations in the past couple of hours have reported gusts from 20 to 35 mph with the higher gusts along the barrier islands/nearshore waters.

Light winds, mostly clear skies and surface dewpoints mainly in the 30s degF will result in temperatures into the upper 30s to mid 50s inland and into the low 60s along the coast. Cooler readings expected across the Brazos Valley and Piney Woods area.
622 AM CDT Wed Oct 16 2024 (Today through Thursday) The most recent surface analysis from the Weather Prediction Center indicates a cold front stretching from Houston to Austin to Dell City. However, another round of scattered showers and thunderstorms is anticipated for Deep South Texas and the Rio Grande Valley on Thursday as precipitable water values briefly increase in tandem with the passage of a 500 mb trough. Finally, with seas increasing along the Lower Texas Coast tonight through Thursday, a High Risk of rip currents will exist at the local beaches at least through that time period.
- Warmer temperatures arrive after today with lows in the 50s and highs in the 70s - 10 to 20 degrees above normal for mid- October.
1220 PM CDT Wed Oct 16 2024 (Today and tonight) Following yesterday evening's FROPA, weak ridging builds in aloft today with the next wave pushing into the northern Pacific. The widespread coldest temperatures in the forecast are expected today with highs in the lower to mid 60s across the forecast area.
Through Thursday Night: An upper-level ridge is building across the central CONUS and has started to build into the Midwest. While some areas last night did experience freezing conditions, the temperatures were not quite cold enough to constitute a deep freeze and officially end the growing season. Therefore, another Freeze Warning has been issued for all of northern IL and northwest IN outside of Lake, IL and Cook counties for the potential for near to below freezing temperatures. After a chilly start to our Thursday, temperatures will rebound into the the low to mid-60s for the afternoon due to the aforementioned warm advection and sunny skies.
As high pressure builds in, we'll begin to see the wind diminish, and wind Thursday should be a good bit lighter than it was today. We are lowering the elevated wild fire danger threat to limited for Thursday based on the low RH forecast with lighter wind. A few locations could dip into the mid 30s over northeast portions of the area, making patchy frost possible, but significant frost is not expected with all lows well above freezing.
1230 PM EDT Wed Oct 16 2024 A trough will move east of the area throughout today as high pressure begins to build in from the west. The high will settle over the region through the weekend. A ridge will continue building into the region this afternoon allowing for enough warming to start shutting off rain chances through this evening.
1245 PM CDT Wed Oct 16 2024 (Today through Thursday afternoon) The long-awaited cold front is making steady progress south through the region early this morning. A strong and gusty northeast wind is ushering in cooler temperatures behind the front. With that said, the windy conditions should make it feel significantly cooler than the observed temperature. Much cooler weather is expected for the afternoon with widespread mid 60s to low 70s. Modest ridging takes back over tonight into tomorrow as large- scale troughing continues to develop to the west.
1201 PM CDT Wed Oct 16 2024 - Temperatures will be much cooler today with breezy conditions diminishing this afternoon. (Today and tonight) In the wake of the cold frontal passage yesterday evening and last night, much cooler air was moving into our area early this morning and accompanied by gusty northeast winds. After highs in the 90-95 degree range yesterday, temperatures will be much cooler today with mostly sunny skies. This to occur as the high pressure system over the Midwest moves east into the Ohio and Tennessee River Valleys.
200 PM EDT Wed Oct 16 2024 * An upper level trough axis will move to the Mid Atlantic Coast this afternoon.
The subsidence associated with this has yielded clear skies over a vast expanse of the central US, with light winds and temperatures in the lower 60s across our county warning area.
This is due to a post-frontal air mass that has arrived behind troughing and an attendant frontal boundary that has crossed further into the Gulf of Mexico. Temperatures will remain much cooler than average for this time of the year with maximums/minimums in the upper 60s to lower 70s/40s to lower 50s, respectively.
126 PM EDT Wed Oct 16 2024 Quiet weather to remain in place through this weekend with high pressure in control. Key Message: 1) Freeze Warning in the mountains tonight and frost advisory east of the Blue Ridge. As high pressure settles in tonight, look for lighter winds and clear skies.
- Cooler temperatures will continue through the end of the work week. /NEW/ /Through Thursday/ Get outside and enjoy the beautiful fall weather that presently sprawls across North and Central Texas! Temperatures are currently 20-25 degrees cooler than they were at this time yesterday.
(This afternoon through Thursday) A strong ridge will be building over Central Alabama through the short term period while the upper-level trough moves east over the Eastern Seaboard.
(Tonight through Thursday night) A cold front has arrived in the Rio Grande Valley from the north- northeast and will bring about more seasonal temperatures and showers/thunderstorms to the region. Temperatures will remain seasonal through the short term period, with temperatures today reaching the upper 80s and temperatures Thursday reaching the lower 80s. Low temperatures will get down to the mid-to-low 60s throughout the the upper Valley and the lower 70s along the coast into the lower Valley. Due to the passage of the cold front, marine conditions are expected to deteriorate, generating rougher surf, which will increase chances for dangerous rip currents along the beaches.
In the wake of the front is a relatively drier and cooler airmass which will provide some cooler temperatures and low rain chances.
(Thursday through next Wednesday) After the chilly morning on Thursday, continued dry weather with a gradual warmup is expected through the rest of the forecast period as an upper level ridge shifts eastward and builds over the eastern CONUS.
50s return across the Lower Trans Pecos and Big Bend. Upper level ridge quickly scoots across the Plains during the day on Thursday and highs across the region tick up a few to several degrees with most spots reaching into the 70s. A weak disturbance moves in behind the ridge tomorrow evening allowing for better ascent.
309 PM EDT Wed Oct 16 2024 An upper level trough axis will slide to the east.
Cold front is continuing to move through southwest Florida at this time with much cooler drier air overspreading the area on breezy north to northeast winds. Strong high pressure will settle over the eastern U. A cold front has moved through the waters with north to northeast winds increasing to Small Craft Advisory criteria. Advisory level winds and seas will persist through the upcoming weekend as high pressure settles in north of the waters. A cold front has moved through the area with breezy north to northeast winds ushering in cooler drier air.
