Aikyam-Lab/Synoptic-Bench huggingface dataset:
Temperatures will be a couple degrees warmer today and 5-10 degrees warmer (near normal) on Friday.
The RAP shows freezing levels falling to around 700 feet AGL across the highest elevations of the Sandhills which are around 4000 feet. Only Boyd county is progged to remain above freezing tonight. Upper level ridging will build northward across the central plains this weekend. A thermal ridge will develop beneath the upper ridge, with mild to warm conditions expected.
648 AM EDT Thu Oct 6 2016 Dry weather and above normal temperatures are forecast to continue today through Friday as high pressure remains centered over New England. A cold front with limited moisture will provide a slight chance of showers Friday night.
346 AM MDT Thu Oct 6 2016 An upper level trof wl be moving acrs the state today. Cooler, below average temps are in store for today with highs mostly in the 50s ovr El Paso county with mainly 60s ovr the rest of the southeast plains, and in the 50s to around 60 in high valley locations. The upr trof wl move out of the area for tonight, with pcpn chances ending. MOS guidance lows for tonight are around freezing acrs all the sern plains.
555 AM EDT Thu Oct 6 2016 High pressure will provide cool, clear nights and warm days through Friday.
While deep layer moisture is expected to increase later in the day and overnight, it will not reach the high PWAT values (2+ inches) observed over the Jacksonville area. Ridging across the Mid Atlantic States extending out into the Western Atlantic will help steer Hurricane Matthew back toward the Florida Peninsula on Thursday.
134 AM EDT Thu Oct 6 2016 High pressure will provide cool, clear nights and warm days through Friday.
525 AM EDT Thu Oct 6 2016 Upper ridge of high pressure will maintain fair weather across our region through Friday night.
1146 PM MDT Wed Oct 5 2016 The lead short wave in the broad upper trough extending from the intermountain west through the plains states continues to lift northeast over the Great Lakes this evening as the second short wave dives into the base of the trough overnight tonight. This second short wave trough begins to lift out across the Central and Northern High Plains during the day on Thursday. A colder high pressure area moves quickly into the central high plains behind a cold front by late Thursday. As skies clear and winds go light Thursday night temperatures will fall into the lower to middle 30s.
115 AM EDT Thu Oct 6 2016 A large 500 mb ridge with above normal lower tropospheric temperatures will dominate our region through Friday evening.
221 AM EDT Thu Oct 6 2016 Dry weather and above normal temperatures are forecast to continue through Friday as high pressure remains centered over New England.
621 AM EDT THU OCT 6 2016 High pressure with dry weather lingering Thursday. Moisture from Matthew from the south and an approaching cold front from the west will increase the chance for rain into this weekend. High pressure will continue the dry weather across the forecast area through the near term period. With the high located to our NE, flow should generally be easterly, which will help keep afternoon temperatures running well above normal across the western slopes and lowlands. The area will be sandwiched between an upper trough approaching from the west and hurricane Matthew which should be moving north up the eastern seaboard.
Low level jet of 40 to 50 kts from the southwest will continue through the morning hours, backing with the approach of the upper trough. Energy ejecting out of the base of the upper trough early this morning will continue to develop convection across western Oklahoma with the cells moving northeast into southern and east central Kansas. High temperatures today will vary from the mid 70s near the Nebraska border to the lower 80s near central Kansas where more sunshine is expected. With northerly winds in place, much cooler conditions are expected Friday with afternoon high temperatures only reaching into the low/mid 60s.
230 AM CDT THU OCT 6 2016 Weather map shows high pressure ridging over most of the eastern U. Don't expect cooler air however, as highs today will reach the lower 90s. About the same story for Friday with highs rebounding into the lower 90s. The weekend continues to shape up with much cooler air and no precipitation across the region.
Will continue to see breezy winds today, albeit significantly weaker than yesterday so no headlines needed, and some sun especially across the southern half of the FA with temps around 50 and a bit cooler in the DVL BSN with thicker clouds. Would not be surprised if the higher elevations of Itasca Park or the Height of Land areas near Park Rapids to saw a dusting of snow. The other area of concern for overnight will be along the International Border as vort lobe swings around the upper low. By Friday the coldest push of 850mb temps rotate around the upper low along with vort lobe at 500mb.
130 AM EDT Thu Oct 6 2016 High pressure will remain in control across the region through the first half of the weekend. Thursday will be another pleasant day and warmer w/most areas apchg 70F or slightly warmer. Quiet weather will persist through Friday night with high pressure keeping its hold on the Northeast. The ridge axis will begin to shift off to our east late Friday and Friday night, placing us in southwest flow. This coupled with plenty of sunshine on Friday will bring temperatures in the lower to mid 70s in most places away from the coast; as is usual the coast will be a few degrees cooler. The high will continue to push to the east as a cold front approaches from the west.
611 AM EDT THU OCT 6 2016 The surface pressure ridge extending into the forecast area from the north will weaken through tonight. The inverted trough will remain near the Georgia and South Carolina coast through tonight.
Another mostly cloudy to cloudy evening is in store as a cold front pushes from central Texas into our area late tonight. The cold front is expected to arrive late Friday morning across the Edwards Plateau area.
140 AM EDT Thu Oct 6 2016 A large 500 mb ridge with above normal lower tropospheric temperatures will dominate our region through Friday evening.
it will be dry with cooler than normal temperatures.
206 AM EDT Thu Oct 6 2016 A large 500 mb ridge with above normal lower tropospheric temperatures will dominate our region through Friday evening.
329 AM CDT Thu Oct 6 2016 Focus for the next 24 hours in this region will be on rainfall chances as mid-upper level wave lifts northeast out of Colorado, followed by influx of cooler temperatures that will settle in for the rest of the week. Then will watch for a second area to develop into our southern areas around Sioux City-Storm Lake by early-mid afternoon, as a warm front lifts north from the central Plains. Much cooler air drops into the region, with sub-zero 850mb temperatures north of I-90 by 12Z Friday, and overnight lows expected to be in the 30s throughout the area.
Lows will remain firmly in the low 60s tonight as SE Michigan remains entrenched in the system warm sector featuring continued elevated Tds and a light southerly gradient. Longwave trough finally begins to collapse and lift NE Friday into Friday night. Cold advection behind the front will dump 850mb temperatures into the low single digits for the weekend, slightly warmer than yesterday's progs. South-southeast winds will then develop during the day in response to developing low pressure over the plains. The low will deepen as it lifts into Wisconsin tonight then into Lake Superior by Friday morning. The low will drive a cold front across Lake Huron late Friday and Lake Erie Friday night, causing the winds to veer to the northwest.
406 AM EDT Thu Oct 6 2016 Another dry and breezy day across the forecast area as high pressure continues to wedge down the Atlantic Coast. Rain chances increase on Friday with the highest pops east central and lowest chances west.
Meanwhile upstream surface obs were revealing a synoptic cold front stretching from northern MN to southwest Neb. Both HRRR/ESLR-HRRR indicate TSRA development along the cold front occuring sometime after sunrise. RAP13 gives PWS values around 2" pooling just ahead of the cold front by this afternoon. A drier/more stable air mass filters in with decent CAA bringing a noticeable cooler conditions on Friday. Time section though advertise temps quickly rebounding this weekend with highs in the low 70s.
high pressure will remain in control through the TAF period for continued dry.
135 AM EDT THU OCT 6 2016 High pressure with dry weather lingering Thursday. Moisture from Matthew from the south and an approaching cold front from the west will increase the chance for rain into this weekend. High pressure will continue the dry weather across the forecast area through the near term period. With the high located to our NE, flow should generally be easterly, which will help keep afternoon temperatures running well above normal across the western slopes and lowlands. Dry conditions under high pressure with southeasterly flow across the area. An upper trough approaches from the west as hurricane Matthew moves northward, our forecast area will be stuck in between for increased PoPs.
Warm conditions will persist today with highs in the lower/mid 90s out west to upper 80s/lower 90s over the northern Coastal Bend and Victoria Crossroads. Above normal temperatures will continue on Friday with highs in the lower 90s.
352 AM EDT THU OCT 6 2016 The surface pressure ridge extending into the forecast area from the north will weaken through tonight. The inverted trough will remain near the Georgia and South Carolina coast through tonight.
The short term period begins with a long-wave trough over the Canada and CONUS with the storm system, that brought much wind and precipitation to Northeast Montana, lifting farther north into Canada. This trough has tapped into cold Arctic air and has dragged the air mass down behind the low pressure storm system. A cool Pacific Ridge has set up over the pacific Northwest and southern British Columbia in response. Tonight into Friday temperatures are expected to again reach freezing overnight as high pressure settles in at the surface and an inversion and cold air drainage become a factor leading to highly stratified temperatures based on terrain.
302 AM CDT THU OCT 6 2016 Current surface analysis indicates low pressure near EKH/SPG with a warm front arcing across northern OK and then northeast toward central MO. Storms should shift north of the region this morning as the warm front retreats north as well, leaving our area fairly quiet thru the bulk of the day. Cooler air behind the front will finally bring more seasonable temperatures to the region on Friday, with highs forecast to drop 20 degrees or so from today's expected highs.
High pressure building over the west coast will bring warmer temperatures today. Upper ridge continues to slide across norcal on Friday bringing more warming with daytime highs jumping to a few degrees above normal for the first time in about a week.
Would not rule out an isolated thunderstorm this evening ahead of the line in the unstable air as the flow aloft backs some as an upper level trough digs across the central Rockies. More significant unsettled weather is expected to begin by Thursday and continue into the weekend as a large upper level trough evolves and digs across the western half of the nation. This upper level trough will allow a cold front to surge south late Thursday night and Friday into Mexico. In the meantime a weakening southern stream upper low is expected to take shape, eject and weaken as it moves across the southwest United States.
Cold Front Arrives Very Late It sure doesn't feel like October across the Missouri Ozarks this morning. All eyes will be just to our northwest this evening as a cold front moves into the region. There will be a sharp divide of temperatures initially on Friday across the Ozarks but as the cold front advances, all areas will see the much cooler temperatures. High pressure settles in for Friday night and the weekend with pleasant weather.
154 AM EDT Thu Oct 6 2016 High pressure will remain ridged over the region today bringing a pleasant autumn day with highs in the 70s.
301 AM EST Fri Feb 17 2017 A ridge of high pressure will bring continued warm and dry weather to eastern Kentucky today and tonight. Cloud cover will begin to increase from the southwest towards dawn tomorrow, and we will finally see precipitation chances return, as an area of low pressure approaches the area from the southwest.
Temperatures are quite cool this morning with deep-layer ridging in place across the region. The ridge should hang around long enough to keep conditions dry through this afternoon. Our current setup will change quickly tonight as the ridge shifts eastward ahead of an approaching upper-level trough.
Benign, dry, and quiet weather through Friday for west- central and southwest Florida as the region rests under stacked surface ridging and ridging aloft. normally warmer spots. High temperatures most spots will reach up into the lower/middle 70s. where the combination of developing afternoon onshore flow and the cooler shelf waters should hold readings in the upper 60s.
1220 AM EST Fri Feb 17 2017 Intense low pressure in the Gulf of St Lawrence will slowly drift towards Newfoundland by Friday morning.
1138 PM CST Thu Feb 16 2017 Warm above normal temperatures will continue this period across Kansas with daytime highs in the upper 60s and 70s, as upper level ridging builds across the central US.
312 AM EST Fri Feb 17 2017 Low pressure will continue to move through the gulf of Saint Lawrence today. High pressure will briefly build across the region tonight.
1055 PM CST Thu Feb 16 2017 Tonight will see light winds again as a weak trough of low pressure drifts into the area. This will lead into a very warm Friday as this trough of low pressure/cool front moves through.
Winds have veered and decreased over the past hour in response to cold front and destabilizing. Temps will be a bit cooler, but still expect highs above seasonal average.
That may lead to a significant cyclone over the middle section of the country late in the week, with the system not reaching the forecast area until after the end of the period.
338 AM CST Fri Feb 17 2017 Early morning water vapor imagery shows upper low now over central TX.
341 AM EST Fri Feb 17 2017 A warm front will lift north across the region today.
1011 PM MST Thu Feb 16 2017 Upper ridge across Colorado today, leading to extremely warm temperatures areawide, with readings near/just short of record maxes at Pueblo and Colorado Springs as of 2130z. On Friday, upper wave moving across the Nrn Plains will push a very weak cold front south through eastern Colorado early in the day, though impact looks to be limited to just some slight cooling of max temps, as mid level heights/temps only fall a minor amount. A few showers may reach the Continental Divide Fri afternoon as moisture increases ahead of West Coast upper low, though precip looks to be spotty and light during the daytime hours.
Currently, upper level ridge pushing east of the Northern Plains replaced with southwesterly flow aloft. Rather potent mid level S/WV trough over the Northern Rockies advancing eastward early this morning. At the surface a trough/cold front extends from southwestern ND north-northeast across my central counties. As the trough moves slowly east through 12Z, high res models indicate westerly winds increasing over my west along with increasing dewpoints. S/WV trough slides east across North Dakota today. West winds expand east in the wake of the cold front this morning along with weak CAA. While we are forecasting cooler temperatures versus the past couple of days, still very mild despite the CAA with decent mixing expected along with periods of sunshine.
High pressure centered along the Louisiana Gulf Coast is ridging across our region this hour, making for somewhat variable winds. This flow, combined with ridging building in aloft, will make for a nice mid February warmup. Cloud cover tonight, again in the Bluegrass, into the morning hours should help us start off warmer compared to this morning.
241 AM CST Fri Feb 17 2017 A temporary rex block will continue over the Plains into the weekend with a cutoff cyclone moving slowly across the Gulf Coast and an upper-level ridge over the central and northern Plains. Along and ahead of the trough the surface to 850 mb flow will turn southwest allowing for good mixing within the 850 mb thermal ridge. This should allow for highs today to be 3 to 6 degrees warmer than we saw on Thu with record highs likely at KOMA/KLNK.
1208 AM EST Fri Feb 17 2017 High pressure will build across the southeastern states through Friday.
323 AM CST Fri Feb 17 2017 Upper low was making its way northeast out of West Texas overnight. Local skies fairly clear save some cirrus that make its way west behind weak upper high to the northwest. Some mid and and high clouds should eventually reach mainly southeastern areas late today and tonight as the upper low takes a more easterly track. Low level temp trends for this afternoon show very similar temps, with again well above normal values with highs in the low to mid 70s anticipated and overnight lows close to normal highs for mid February.
100 AM EST Fri Feb 17 2017 Upslope and lake-enhanced snow showers will diminish overnight as high pressure starts to build into the area from the west. An occluded cyclone /968 hPA/ continues to be near the Canadian Maritimes. High pressure is building in from the lower Great Lakes. These should end prior to daybreak with the lowering subsidence inversion. With the high pressure area passing over the area, plenty of sun is expected on Friday.
327 AM EST Fri Feb 17 2017 Split flow across the CONUS features an upper low across Texas and a building mid level ridge across the upper Ms Valley/wrn Great Lakes. This mid level ridge will expand across Lower Mi today, while the upper low over Texas drifts to Oklahoma. The sfc warm front will nudge into SW Lower Mi. The mid level ridge will dampen as it pushes east of Lower Mi tonight as a mid level short wave impulse races from ND across Lake Superior. This will result in a tightening of the low level westerly gradient, leading to a core of strong winds above the shallow stable layer across srn Lower Mi. This will drive the sfc warm front across the forecast area, with 925mb temps forecast to rise to a record +12C overnight.
A weak lee trof will bisect the region today. There will be less downslope winds compared to yesterday, and thus highs will be a few degrees cooler.
Upper level ridge over the area and do expect a good deal of sunshine and winds will turn west-southwest this afternoon, esp in the RRV and eastern ND. A weak trough will extend south of the low and move into the RRV this aftn and along and west of this winds to turn the west or southwest. This will aid in warming so did go on the high end of guidance.
231 AM EST Fri Feb 17 2017 High pressure will build in from the west today and will crest over the region tonight as a warm front lifts into the northeast.
1037 PM CST Thu Feb 16 2017 Tonight will see light winds again as a weak trough of low pressure drifts into the area. This will lead into a very warm Friday as this trough of low pressure/cool front moves through.
The forecast H850 temperature of 15C are warmer than anything measured by the MPX raob according to the SPC climatology site.
310 AM EST Fri Feb 17 2017 A warm and sunny Friday is in store for the region with upper level ridging in place and a strong southerly flow. Temps should easily warm into the low to mid 60s this afternoon. Lows will range through the low to mid 40s with the coolest locations over southeast IN and the KY Bluegrass.
Convective showers have developed this evening along a passing Pacific cold front from near Butte northeast to Fort Benton, including the Helena and Great Falls areas, where wind gusts in excess of 45 mph occurred. A Pacific cold front has pushed through the forecast area, but lingering moisture/lift in the wake of the front is keeping SHRA/SHSN going, mainly impacting areas near KGTF/KLWT/KHLN/KBZN.
A dry, warm airmass was in place across the central plains early this morning under the influence of upper ridging across the northern and central plains. Have followed closer to the rap for highs today with readings ranging from the mid/upper 60s in our northwest zones to the low/mid 70s in our southeast zones. Forecast soundings indicate post frontal mixing in our western counties near h85 with winds at the top of the layer around 20kts and cannot rule out a couple of hours with wind gusts near 20 mph or so and combined with low relative humidity values in the low 20th percentile, will mention near critical fire weather conditions in the HWO for locations west of a line from Elwood/Lexington to Ord.
1100 PM CST Thu Feb 16 2017 Latest surface analysis indicates a warm front was lifting slowly north across the forecast area early this evening. High pressure continues to dominate the weather map across much of the Plains and Midwest this afternoon. However, a weak warm front continues to move through the region this afternoon, and southerly winds usher in warmer temperatures. The warm temperatures are part of a longer warming trend, and tonights lows will remain above freezing for Central Illinois.
1032 PM MST Thu Feb 16 2017 Upper level ridge across the Northern Plains this afternoon. Weak cold front slips through the area Friday with highs around 10F cooler than today.
326 AM EST Fri Feb 17 2017 High pressure builds overhead through late morning.
345 AM EST Fri Feb 17 2017 A warm front will move north through the area today bringing well above normal temperatures to the region with record high temperatures possible heading into the weekend.
A ridge extends from the Northern Gulf of Mexico northwards to the Northern Plains. A closed low is currently spinning across Texas and will impact the weather just beyond the short-term forecast period. At the surface, a ridge of high pressure stretches from the Northern Gulf Coast into the Great Lakes region. The closed low currently across Texas will transitions into an open wave and track to the northeast into the Mid-Mississippi River Valley by late tonight.
Upper ridge axis will be positioned overhead by the afternoon hours and with southwesterly flow the mercury will continue to rise.
A weak ridge of high pressure will build into the region early this afternoon.
427 AM EST Fri Feb 17 2017 High pressure will bring clearing skies today along with seasonal temperatures.
324 AM EST Fri Feb 17 2017 High pressure will build across the southeastern states today.
The thermal ridge will be passing directly overhead, with moderate southwesterly surface flow, ample sunshine, and relatively low dewpoints.
Clear skies prevailed across the greater Tennessee Valley and surrounding region, thanks to a light southerly flow around an area of high pressure over the NE Gulf of Mexico. Some higher altitude clouds exiting south of northern stream were moving this direction, but dissipating over the mid Mississippi Valley, as they moved into short-amplitude ridging building across the southern states. Lows overall should be warmer mainly in the mid 30s most locations, but around 30 in the colder spots. The work week will end on dry and warmer note.
252 AM EST Fri Feb 17 2017 Drier and cooler air has pushed across South Florida this morning with temperatures beginning to fall with 40s sneaking into southern central Florida and solid 50s across much of southern Florida save for some east coast sites. Some portions of the interior could see temperatures reach into the lower 80s today. Preferred a slightly warmer blend of models for today, especially over the interior, which was about a degree warmer than the blend.
1253 AM EST Fri Feb 17 2017 Skies will begin to clear Friday as low pressure moves northeastward.
