Aikyam-Lab/Synoptic-Bench huggingface dataset:
/NEW/ /Through Thursday Night/ Dry and calm weather can be expected to persist through Thursday night as a mid-level ridge continues to control the synoptic pattern. Elevated fire weather conditions are expected this afternoon, primarily west of the I-35 corridor where warmer temperatures and subsequent lower relative humidity values will reside. Slightly cooler temperatures in the low 80s are expected for East Texas Thursday afternoon, with a few readings in the upper 70s not out of the question. Locations along and west of the I-35 corridor will be warmer with temperatures in the upper 80s and low 90s as surface winds remain predominantly southerly through the day.
As the high takes hold the northeasterly winds will continue to advect in cooler air from the north which will allow overnight lows across much of the area to mid to upper 30s with 40s expected in the Chicago metro. Winds are also expected to ease this evening as the high moves in with speeds becoming less than 5 mph. Otherwise, expect mostly to partly sunny skies for our Thursday with fall-like conditions in the low to mid-60s and overnight lows in the upper 30s and lower 40s inland with mid-40s in the metro. The broader pattern across the CONUS will remain somewhat blocked with a partially cut-off trough across the Rockies and the remnants of Hurricane Ian stalling over the southeast states.
Highs are only expected to top out in the low to mid 60s for most, with perhaps a couple of upper 60s possible at the typical warm spots and in our far SW counties. Given that we only saw a few reports of patchy frost this morning with overall cooler and more widespread temps in the 30s, think we'll hold off on any SPS frost mention for now. The latest NHC forecast has Tropical Cyclone Ian moving northward through the Southeast US and towards the Appalachians while it weakens.
(This evening through Thursday) A pressure trough/weak surface front continues to slowly drift across the I-44 corridor (roughly Walters-Chickasha-Guthrie, OK line) this afternoon. HIs will range from the low to mid-90s ahead to mid-80s behind the front. The front will begin to "wash out" overnight across the far southern CWA, with overnight lows ranging from the low-60s (south) to low-50s (northwest). An area of Canadian high pressure, currently settling across the Upper Midwest, will influence sensible weather across the area on Thursday. Areas along and east of the I-35 corridor will notice "cooler" afternoon HIs (ironically still a few degrees above climo normals) in the low-80s.
245 PM CDT Wed Sep 28 2022 An upper trough continues to dig into the mid-Atlantic region this afternoon as a weak upper ridge begins to slide into the southern plains. A back door cold front arrived last night knocking temperatures down to around normal for this time of year as this afternoon's temperatures reside from the mid 70s to low 80s.
1202 PM PDT Wed Sep 28 2022 The arrival of a low pressure system Wednesday and Thursday will bring cooler temperatures and areas of rain.
145 PM CDT Wed Sep 28 2022 (Issued 145 PM CDT Wed Sep 28 2022) Tonight through Thursday night: High pressure will continue to build across the area tonight. The core of the high pressure is expected to shift through the eastern lakes into the northeast US by later Thursday night. The westward ridging of this high will maintain its influence this period.
Weakening high pressure and increasing onshore flow will bring about a cooling trend area-wide that will continue into the weekend.
Issued by National Weather Service Memphis TN 1225 PM CDT Wed Sep 28 2022 (Wednesday through Thursday) An upper ridge centered over Eastern New Mexico/West Texas will continue to dominate our weather today but will weaken slightly on Thursday. Farther east, northeasterly winds will be stronger, as will the cool air advection, which should keep daytime highs in the lower 80s in South Central Arkansas and Northeast/North Central Louisiana. These factors will delivering a reinforcing surge of cooler air into the region.
353 PM EDT Wed Sep 28 2022 A cold front is pushing through the region today with scattered showers. High pressure and dry weather move in on Thursday and persists into the weekend. A cold front with showers is sliding south this afternoon. By that time the saturated moisture drops to the lowest 5k feet. A large area of high pressure will build southeast to be over upstate NY Thursday night.
1118 AM CDT Wed Sep 28 2022 (Today through Thursday afternoon) Upper ridge centered over the region again today, as one trough swings across the NE US another one arrives on the NW coast. This 2nd trough will flatten the ridge as it moves inland Thursday.
With an upper high remaining over the area and thicknesses not moving much, tomorrow will be similar to today, with highs in the 80s on the Caprock, and near 90F off the Caprock! Elsewhere around the nation (something that will have zero effect on west Texas).
118 PM CDT Wed Sep 28 2022 (Today through Thursday) Another dry cold front has moved through the area, bringing continued CAA and drier air to the mid state today. Northeast winds around 10 to 15 mph and gusts to around 25 mph will mix the low levels well, and bring in drier air to the surface, but the cooler highs should keep min RH values around 30 percent or higher for the eastern half. Slightly warmer temps in the east and south will drive min RH values to around 20 to 25 percent, and marginal fire danger conditions will be in place.
258 PM MDT Wed Sep 28 2022 Today will be the final day of much warmer than normal temperatures as the cutoff low begins to influence the state the remainder of the week. Ahead of this low, moisture is beginning to push northward into the state, evidenced by the increased CU field.
Remnants of "Ian" looks to move north and west to the Tennessee Valley over the weekend with models still struggling some on interaction/phasing potential of this feature with a weak trough diving south into the Great Lakes Sun into Mon.
212 PM CDT Wed Sep 28 2022 Autumnal weather continues under a clear sky with below normal temperatures today thanks to robust cold air advection in the low-levels. Temperatures will be a couple degrees warmer tonight than last night, which will keep the risk of frost out of the area. MRM A mid-level ridge will spread across the southern CONUS Thursday, helping surface temperatures to begin to moderate.
At the surface we have a high pressure centered west of the Great Lakes region extending south to the western Gulf Coast. Overhead there is an upper level high centered SE of the Four Corners States with a trough over the east coast with attached frontal boundary that made its way thru our area previously. This will pull cooler and drier air down into the region.
(Through Thursday) Breezy northeast winds are expected overnight into Thursday as Hurricane Ian moves across the Florida peninsula and high pressure is situated to the north over the Midwest. The funneling from the north and some mid/high clouds overtop much of the area will keep highs Thursday in the low to mid 70s.
The low levels will start responding to an incoming large upper low with lee trough development on Thursday. The warming lower troposphere with increased lower-mid tropospheric downslope will help temperatures top out from the lower 90s out around Elkhart to the lower 80s toward central/south central Kansas where surface winds will still have some easterly component to them.
(This afternoon through Thursday night) High pressure aloft, dry surface conditions, and surface winds less than 5kts at/around sunrise will favor another night of good radiational cooling conditions and below normal low temps. Aforementioned high pressure aloft will remain in place Thu PM and the low-level thermal ridge will be across the far ern CWFA.
209 PM EDT Wed Sep 28 2022 Upper level trough and cold temperatures aloft will lead clouds with scattered showers mainly across the Great Lake today. This high will slowly drift east across the Great Lakes through the end of the week resulting in dry weather. Mean long wave trof continues from the Great Lakes through New England. Clouds and a northerly wind will keep high temperatures cool today, ranging from the upper 50s north to the lower 60s south. Lows will drop once again to the lower 40s, with mid 40s expected in urban areas. Highs will still be below normal but warmer than today. They should range within 3 degrees or so of 65, cooler to the north and warmer to the south.
(Tonight) High pressure will continue to keep conditions dry through the night. An increase in pressure gradient will keep winds elevated overnight, especially in the higher terrain. We could see gusts 15-20 mph but in the higher terrain 25 to maybe 30 mph are possible.
A cold front will move through late in the period bringing a chance for showers and cooler temperatures. High pressure was in control across the region bringing mainly sunny skies and dry conditions. The high will begin to shift to the east tomorrow setting up southerly winds across the region that will bring more warmth that will last into the weekend.
1247 PM CDT Wed Sep 28 2022 Today and Tonight: Early morning satellite imagery showed the circulation around a large upper level trough over the eastern CONUS that will lift out to the northeast through the period. The strong gusty winds combined with the low relative humidities will result in a significant threat of wildfires today. Warmest temperatures are expected in the west and will be near normal in the lower 80s while much of our eastern zones will not make it out of the 70s. Under clear skies and a light northeast wind, radiational cooling of our dry airmass will lead to cooler than normal morning lows in the upper 40s to lower 50s.
240 PM CDT Wed Sep 28 2022 For tonight, relative humidity (RH) values will climb back up between 60-75% as temperatures dip into the the low 50s to upper 40s. Otherwise, expect morning temperatures in the low 50s with afternoon temperatures peaking in the mid 70s.
Pacific surface cold front passed Burns/OR mid- afternoon and wind shifted to west 25-30 mph, but a gust of 52 mph was recorded there just after 6 PM PDT.
959 PM CDT Wed Sep 28 2022 (This evening through Thursday) A pressure trough/weak surface front continues to slowly drift across the I-44 corridor (roughly Walters-Chickasha-Guthrie, OK line) this afternoon. HIs will range from the low to mid-90s ahead to mid-80s behind the front. The front will begin to "wash out" overnight across the far southern CWA, with overnight lows ranging from the low-60s (south) to low-50s (northwest). An area of Canadian high pressure, currently settling across the Upper Midwest, will influence sensible weather across the area on Thursday. Areas along and east of the I-35 corridor will notice "cooler" afternoon HIs (ironically still a few degrees above climo normals) in the low-80s.
High pressure will build in its place promoting warmer and drier conditions across the region during the second half of the week and this weekend. Today's trough and associated weak front brought about 0.
This afternoon through Thursday night An upper Low is currently moving inland onto the Oregon/Washington coast as the amplified upper ridge continues to move eastward into the central US. The approaching trof will tighten gradients, bringing breezy to windy conditions this afternoon and evening. The trof moves through Nevada tonight through tomorrow night. The system's cold front will move across the state on Thursday, which is not expected to bring any precipitation, though it will start a cooling trend, mostly felt at first in northern Nevada.
520 PM MDT Wed Sep 28 2022 Semi-blocked pattern with a long wave ridge over the central CONUS will slowly allow eastern progression as a trough drops into the northern Rockies. Lee side trough will begin to shift east over the Northern Plains tonight, with an associated LLJ revving up over scentral SD. Upper trough will shift east and allow for increasing moisture and lift aloft, supporting increasing chances for showers and a few storms.
632 PM CDT Wed Sep 28 2022 Autumnal weather continues under a clear sky with below normal temperatures today thanks to robust cold air advection in the low-levels. Temperatures will be a couple degrees warmer tonight than last night, which will keep the risk of frost out of the area. MRM A mid-level ridge will spread across the southern CONUS Thursday, helping surface temperatures to begin to moderate.
234 PM PDT Wed Sep 28 2022 Breezy southwest winds will continue through early evening as a low pressure system tracks across the Pacific Northwest. Expect quiet fall weather for the next several days as dry conditions, lighter winds, and seasonable temperatures prevail as high pressure once again builds over the region. Highs will generally warm into the low 80s across western Nevada valleys with with low to mid-70s for Sierra valleys. Overnight lows will also be around season norms with colder Sierra valleys dipping to near freezing overnight as our limited cloud cover tracks eastward as the trough departs.
Ian has not developed a well-defined tail of convection that commonly forms as tropical cyclones move poleward.
(Tomorrow through Wednesday) Overall, more of the same as a blocking pattern established between remnants of "Ian" and Pacific NW trough which becomes cut off as main westerlies retreat back into Canada. Resultant ridging at the surface an aloft will keep persistent pattern of cool nights, warm days with very low daytime humidity, which offers no help in terms of fire weather. NBM forecast daytime highs generally accepted, while lows will continue to be nudged toward cooler CONSMOS, especially in areas that normally see more efficient radiational cooling.
The coastal communities that are already gusty from the pressure gradient squeeze between the high to the north and approaching storm, will have winds increase in speed.
928 PM CDT Wed Sep 28 2022 (Issued 928 PM CDT Wed Sep 28 2022) Temperatures have already dropped into the upper 30s to mid 40s across most of the area with warmer temperatures along the lake. Forecast is still on track for temperatures to fall into the low to mid 30s by early Thursday morning with 40s along Lake Michigan. RAH (Issued 145 PM CDT Wed Sep 28 2022) Tonight through Thursday night: High pressure will continue to build across the area tonight. The core of the high pressure is expected to shift through the eastern lakes into the northeast US by later Thursday night. The westward ridging of this high will maintain its influence this period.
639 PM CDT Wed Sep 28 2022 (Tonight through Thursday night) Upper level high pressure system continues in control across the Rockies and Southern Plains. At the surface, a ridge of high pressure is forecast to dominate the local area through the short term period. Therefore, expect another cooler night with lows in the mid 50s across the Hill Country, lower 60s along I-35 corridor and mid 60s along the Rio Grande. Therefore, Thursday's overnight lows are forecast to be even cooler with some spots getting to the lower 50s across the Hill Country and between the mid 50s and mid 60s elsewhere.
Y area (mainly NW/W of GRB) will probably drop to/below freezing, but at this point the best course of action seems to be to just maintain the FR. Lows tonight are expected to range from 25 to 30 across the north, with lows in the lower to middle 30s elsewhere. Wisconsin will be positioned between upper troughs over the Rockies and the southeast United States.
630 PM EDT Wed Sep 28 2022 A cold front is pushing through the region today with scattered showers. High pressure and dry weather move in on Thursday and persists into the weekend. The cold front is dropping through northeast PA this evening, with some lingering showers from the Southern Tier southward. By that time the saturated moisture drops to the lowest 5k feet. A large area of high pressure will build southeast to be over upstate NY Thursday night.
Skies are clear, but we are still a little warm in TX with low to mid 70s, while much of our sites along and E of I-49 are much cooler in the 60s and even upper 50s and lower 60s in S AR. We will keep a good spread at daybreak with no fog or anything, and just a welcomed cooler trend that may even keep highs in the 70s areawide. The cooler trend will bottom out tomorrow night with ideal radiational cooling.
932 PM EDT Wed Sep 28 2022 An upper level trough will cross the area tonight, then lift out to the northeast Thursday.
605 PM EDT Wed Sep 28 2022 (Through Thursday) Breezy northeast winds are expected overnight into Thursday as Hurricane Ian moves across the Florida peninsula and high pressure is situated to the north over the Midwest. The funneling from the north and some mid/high clouds overtop much of the area will keep highs Thursday in the low to mid 70s.
747 PM CDT Wed Sep 28 2022 (This evening through Thursday Night) An upper ridge centered over Eastern New Mexico/West Texas will continue to dominate our weather. These factors will delivering a reinforcing surge of cooler air into the region.
614 PM CDT Wed Sep 28 2022 (Tonight) High pressure will continue to keep conditions dry through the night. An increase in pressure gradient will keep winds elevated overnight, especially in the higher terrain. We could see gusts 15-20 mph but in the higher terrain 25 to maybe 30 mph are possible.
358 PM MDT Wed Sep 28 2022 Today will be the final day of much warmer than normal temperatures as the cutoff low begins to influence the state the remainder of the week. Ahead of this low, moisture is beginning to push northward into the state, evidenced by the increased CU field.
This nudge is to account for surface winds holding up and a bit better probability temps stay a tad warmer. /CME/ For tonight, relative humidity (RH) values will climb back up between 60-75% as temperatures dip into the the low 50s to upper 40s. Otherwise, expect morning temperatures in the low 50s with afternoon temperatures peaking in the mid 70s.
The pressure gradient between Hurricane Ian over FL and a high pressure system over WI will help maintain a NNE breeze, and this will tend to mix the near surface air a little.
Tonight into Thursday and as the cyclone departs, winds will become northwest at all terminals.
Periods of locally breezy winds, strongest this evening through the Delta and Sierra ridgetops. Current visible satellite imagery shows some bands of moisture in the form of high clouds associated with an upper level trough passing over northern California this afternoon. This trough will move over the Pacific Northwest over the next day or so, with the main impacts being slightly cooler temperatures and locally breezy onshore winds through the Delta and over the Sierra ridgetops through this evening. As this trough shifts eastward, the winds will shift from the west-southwest to the north direction Thursday.
An upper trough continues to dig into the mid-Atlantic region this afternoon as a weak upper ridge begins to slide into the southern plains. A back door cold front arrived last night knocking temperatures down to around normal for this time of year as this afternoon's temperatures reside from the mid 70s to low 80s.
(Rest of tonight) Evening model guidance suggests that moderate north-northwest flow aloft will persist across the TN Valley overnight, along the southwestern flank of an amplified longwave trough across the northeastern CONUS.
617 PM CDT Wed Sep 28 2022 (This evening through Thursday) A pressure trough/weak surface front continues to slowly drift across the I-44 corridor (roughly Walters-Chickasha-Guthrie, OK line) this afternoon. HIs will range from the low to mid-90s ahead to mid-80s behind the front. The front will begin to "wash out" overnight across the far southern CWA, with overnight lows ranging from the low-60s (south) to low-50s (northwest). An area of Canadian high pressure, currently settling across the Upper Midwest, will influence sensible weather across the area on Thursday. Areas along and east of the I-35 corridor will notice "cooler" afternoon HIs (ironically still a few degrees above climo normals) in the low-80s.
615 PM MDT Wed Sep 28 2022 Today will be the final day of much warmer than normal temperatures as the cutoff low begins to influence the state the remainder of the week. Ahead of this low, moisture is beginning to push northward into the state, evidenced by the increased CU field.
Quiet weather continues across the region as weak upper level ridging builds overhead and amplifies a bit into the weekend.
727 PM EDT Wed Sep 28 2022 Upper level trough and cold temperatures aloft will lead clouds with scattered showers mainly this evening across the Great Lakes. This high will slowly drift east across the Great Lakes through the end of the week resulting in dry weather. Mean long wave trof stretches from the Great Lakes through New England. Expect cool lows from near 40 to the lower 40s. Temperatures will still be below normal but trending warmer. Highs to range from the lower 60s far north to the upper 60s south.
624 PM CDT Wed Sep 28 2022 For tonight, relative humidity (RH) values will climb back up between 60-75% as temperatures dip into the the low 50s to upper 40s. Otherwise, expect morning temperatures in the low 50s with afternoon temperatures peaking in the mid 70s.
We continue to see the stubborn mid/upper ridge remaining anchored across the central CONUS through the beginning of the work week leading to a continuation of mild and dry weather conditions.
Temps will range from the lower 70s in western Iowa to upper 70s in Fairbury, Lincoln, Albion, and such on our western periphery. The ridge situated between Ian's remnants and a cutoff low meandering across the central Rockies allows temps to push above late September norms.
So far precipitation has been showery, but as the system slows down and settles into a blocking pattern with upper level ridge that remains in place over Canada, it will transition to more stratiform precipitation.
1144 PM CDT Wed Sep 28 2022 (Rest of tonight) Evening model guidance suggests that moderate north-northwest flow aloft will persist across the TN Valley overnight, along the southwestern flank of an amplified longwave trough across the northeastern CONUS. (Thursday through Friday night) An upper level trough coming onto the west coast will amplify the vast ridge in place across the central CONUS and run into the trough across New England. This eastern trough will affect Hurricane Ian which all eyes are on.
(Today through Friday) Dry conditions continue, but the cooler high temperatures are preventing min RH values from getting as low as earlier this week. Enhanced low level mixing with strong winds and dry air aloft may bring min RH values to around 20 to 25 percent for some areas, especially west and south where temps may get a few degrees warmer.
After a chilly start in the 30s to lower 40s, sunny conditions will help temperatures rebound to the lower to upper 60s by afternoon, warmest across the southwest counties. A blocking pattern aloft, with an upper ridge over the Central U. VFR and light winds will continue through tomorrow with high pressure in control.
Significant coastal flooding is ongoing across vulnerable low-lying areas on the Bayside of the Upper Keys, and we expect this to continue for the next couple of days, with little if any relief during the low tides. However, areas of leftover street flooding in low-lying sections of the Lower Keys, including Midtown and New Town Key West, will take some time to abate.
338 AM CDT Thu Sep 29 2022 (Issued 338 AM CDT Thu Sep 29 2022) Today and Tonight: High pressure over the Great Lakes Region early this morning will continue to slowly shift northeast and meander into the New England States late tonight. With high pressure overhead this morning, mostly clear skies and chilly temperatures are expected. Warmer water temperatures will keep the lakeshore areas warm enough to keep the frost at bay.
(Today and tonight) Upper level high pressure and dry mid to upper levels will remain over the forecast area today.
24 hour temperature delta map showed similar to last evening, but around 3 to 5 degrees cooler over east AR.
