A short wave trough over the Colorado River Valley at the CA/AZ border will continue to move eastward flattening the upper level ridge over the Southern Plains by Wed. This will promote warm westerly downsloping winds that will bring warmer temperatures into the area by Wed.
The Freeze Warning and Frost Advisory were allowed to expire earlier, as temps gradually began to rebound above the lower/mid 30s. With a strong dome of high pressure continuing to drift ENE into the mid/srn Atlantic states, temps later today look to climb mainly into the mid 60s for most spots, under predom sunny skies. By the middle of the week, the ridge axis across the southern CONUS shifts farther east, backing the flow aloft to more westerly.
1200 PM EST Tue Nov 3 2020 High pressure will remain in control of the weather for most of the week. The overnight cirrus has cleared and little change was needed to the afternoon highs, which should run about 10 degrees warmer than yesterday. Lows tonight were untouched, also about 10 degrees warmer.
/issued 339 AM CST Tue Nov 3 2020/ A steady warm up will continue today under ridging aloft and increasing southerly sfc flow. A shrtwv trof will pass over the region tomorrow causing winds to shift out of the WSW which will help add a few degrees to our high temperatures.
1153 AM EST Tue Nov 3 2020 Warmer temperatures will continue to arrive through the upcoming week with highs in the 60s and eventually even some 70s heading towards the weekend. Return flow on the back side of a high pressure area will increase today and allow warmer air to flow back into the region.
218 PM CST Tue Nov 3 2020 Tonight and Wednesday: High pressure at the surface continues to slide east of the region through the short term period. This, while ridging aloft steadily increases from the west. Then Wednesday afternoon, highs will top out in the low and middle 70s under sunny skies. /19/ Wednesday night through Tuesday: Come Wednesday evening a >1028mb high will be centered just off the mid Atlantic seaboard and ridging back across the Gulf coast states.
Morning temperatures have remains mild in the 40s especially along and west of the RRV escarpment with lower temps near freezing mainly in valley.
905 AM CST Tue Nov 3 2020 The Freeze Warning and Frost Advisory were allowed to expire earlier, as temps gradually began to rebound above the lower/mid 30s. With a strong dome of high pressure continuing to drift ENE into the mid/srn Atlantic states, temps later today look to climb mainly into the mid 60s for most spots, under predom sunny skies. By the middle of the week, the ridge axis across the southern CONUS shifts farther east, backing the flow aloft to more westerly.
SHORT TERM (Now through Wednesday Night): 500mb ridging centered overhead will continue to provide strong subsidence across the area through the period. At the surface, high pressure across the northern Gulf coast this afternoon will gradually move eastward off the Mid- Atlantic coast by Wednesday night. Highs on Wednesday will reach the low 80s to mid 80s at most inland areas and the mid 70s along the coast.
South of this low a decent pressure gradient resides across western and central ND today, with a steady westerly wind of 15 to 20 mph and a few gusts occasional to 30 mph. Embedded S/WV slides east across North Dakota on Wednesday, and will result in another day of gusty west winds and slightly cooler temperatures.
Winds this afternoon will generally be light and variable as high pressure builds east across the area. /19/ It was a chilly start to the day across the CWA, as temperatures bottomed out from near freezing to the upper 30s.
215 PM EST Tue Nov 3 2020 Canadian high pressure continues to provide cold, dry air through Wednesday. High pressure overhead is the dominant feature for the next 36 hours with dry weather and clear skies. With light wind and clear skies associated with the high pressure system, good radiational cooling is expected again tonight with some patchy frost in some locations, mainly inland, although not as widespread as last night. Temperatures will warm closer to normal for both highs in the 70s and lows in the 50s Wednesday & Wednesday night as the high pressure influence continues.
200 PM EST Tue Nov 3 2020 High pressure will remain over the southeastern United States and temperatures will slowly increase through the week. Clear skies and calm winds with the location of the high will allow for excellent radiational cooling conditions overnight.
325 PM EST Tue Nov 3 2020 Water vapor imagery highlights a long wave trough pivoting east through the western North Atlantic. Mean layer ridging over the western Gulf of Mexico and Mexico is lending to subsidence over Florida and the eastern Gulf of Mexico. This ridging has also stalled Hurricane Eta near the coast of Nicaragua. MIMIC TPW loops and visibile satellite imagery highlight a sharp warm frontal axis developing over the Windward Passage and Jamaica. This trough axis will pivot around the broader circulation of Eta, as Eta decays over Central America. This inverted trough axis/warm frontal boundary will be on our doorstep Wednesday afternoon, overtaking the mC airmass.
945 AM MST Tue Nov 3 2020 Synoptic Overview: An upper level ridge, currently extending northward from the GOMEX into the Central High Plains, will flatten on Wednesday. as a deamplifying upper low (presently situated in central CA) progresses east across the 4-Corners (tonight) and Central/Southern Plains (Wed). as an upper level ridge amplifies over the Desert Southwest (Wed night), extending NNE into the Central/Southern High Plains (Thu). Tonight: Increasing upper level cloud cover -- in advance of the deamplifying upper low progressing east across the 4-Corners and Central/Southern Rockies -- will likely have some impact on radiational cooling. With this in mind, expect somewhat warmer lows in the lower 40s. Expect mostly clear skies with highs in the mid-upper 70s and lows in the lower-mid 40s.
It was a chilly start to the day across the CWA, as temperatures bottomed out from near freezing to the upper 30s.
A southwesterly breeze on the north side of high pressure centered over the deep south will continue a slow warming trend tonight, with lows dipping to the upper 30s to lower 40s under clear skies.
1237 PM EST Tue Nov 3 2020 Dry weather continues as high pressure settles in for the rest of the week and into the weekend. Clear, dry weather will continue as high pressure settles in and remains in control for the duration of the near term period. Model soundings indicate an inversion will set up tonight resulting in cooler temperatures in the valleys. Lows tonight are expected to range from mid 30s to 40 degrees in the lowlands and upper 20s to mid 30s in the mountains. Southwest flow in the low levels will pull warmer air into the area allowing temperatures to rise above normal on Wednesday. High's are forecast in the mid to upper 60s for the lowlands and 50s to mid 60s in the mountains.
Upper ridge will flatten this afternoon ahead of a weak upper disturbance. Winds will be light in the valleys, with gusty winds developing in the higher elevations this afternoon.
1026 AM MST Tue Nov 3 2020 A weak upper-level low pressure system continues to bring scatter mid and upper-level clouds to the Four Corners region this Tuesday morning. Thinking is that the HRRR/NAM Nest may be better resolving/modeling this low level dry air, and likely producing a much more realistic forecast. precipitation totals will be no more than a trace to a hundredth of an inch or so even in the higher terrain. The weak upper-level low pressure system will deamplify and shift east of the divide early on Wednesday.
At the sfc, a weak low pressure area will slowly move across srn Canada while a large high pressure area remains over the se USA and adjacent Atlantic Ocean.
/Tonight through Tomorrow Night/ Upper-level ridging will continue to pull east, as a trough begins to move through the midwest. This ridge movement will allow for transport winds to shift back to the south and southeast. However, cooler ground temperatures will help to absorb some of this afternoon heating and warm-air advection.
140 PM EST Tue Nov 3 2020 Warmer temperatures will continue to arrive through the upcoming week with highs in the 60s and eventually even some 70s heading towards the weekend.
Some of the highest gusts along the Reef Tract reached the high 30s. Dewpoints fell into the lower 60s with overnight lows in the lower to mid 70s. The SST sensor in Key West Harbor fell from 83 to 81 in 24 hours, while at the same time, the relatively shallow waters of Florida Bay fell from the lower to mid 80s to near 70. After 72 hours, a developing trough over the northern Gulf of Mexico should cause Eta or its remnants to turn northward and then northeastward.
With a better chance for some cloud cover as we move from 10th percentile moisture to closer to average some temperatures could be slightly cooler tomorrow. Cloud cover is not expected to be widespread enough to lead significantly cooler weather.
251 PM EST Tue Nov 3 2020 High pressure will build across the southeastern US tonight, then migrate offshore for the remainder of the week.
1112 AM CST Tue Nov 3 2020 A broad upper-level ridge will dominate the region today with large- scale subsidence as it progresses eastward into the central U. At the same time, low-level flow will become increasingly southwesterly and continue to advect warmer air into the Midwest evidenced by 850- hPa temps rising to 15C by the afternoon. On Wednesday, the southwesterly low-level flow will continue and strengthen upon approach of a compact upper-level trough exiting the Rockey Mtns as the ridge shifts into the eastern U. Although some thin upper-level clouds may arrive during the afternoon, this evolution should lead to even warmer high temps Wednesday--as much as 10 to 20F above average.
1210 PM EST Tue Nov 3 2020 High pressure builds into the area today and will settle along the coast on Wednesday.
1001 AM EST Tue Nov 3 2020 High pressure will build across the southeastern US today, then migrate offshore for the remainder of the week. These winds will gradually lessen through the day as mid level troughing loses its influence on the area and the surface gradient slackens as high pressure builds into the southeastern states. As a longwave trough exits into the Canadian Maritimes, mid- level heights rebound considerably. A temperature inversion above the boundary layer will stunt some of this warming trend, but expect highs to be around 10 degrees warmer than the previous day. Upper 50s to low 60s can be expected over much of the region with 40s to low 50s across the Blue Ridge and Allegheny Front.
The short term forecast remains quiet as high pressure remains in control. Dew points will slowly creep up overnight which will keep our lows roughly 10 degrees warmer tonight. Our quiet weather pattern will persist through the day Wednesday with highs reaching the upper 70s along the coast to the low 80s out west.
The flow will become more zonal with some weak ridging trying to build into the area toward the end of the week. Cold, cold temps this morning have risen into the low and mid 60s across the area this afternoon. The trough has moved off to our northeast, and led to negligible temperature advection in the lower levels, which has allowed us to warm like we have today.
1136 AM EST Tue Nov 3 2020 Canadian high pressure continuing to provide cold, dry air through Wednesday. Latest sfc analysis shows broad 1028 mb high pressure centered over MS. Aloft, deep NW flow continues behind an upr-level trough pushing farther offshore. Slight warming trend continues into Wed with high pressure sliding off to the NE. High pressure and dry air will continue to bring quiet weather on Wednesday night.
1241 PM EST Tue Nov 3 2020 High pressure will build over the region both at the surface and aloft and linger over the area through the end of the week. Winds will decrease today and temperatures will be slightly warmer. Otherwise, the near term period will be tranquil with a warming trend as 850mb temperatures rise back toward +10C during the next 24 hours as the upper trough and associated cold air mass lifts out of the eastern U. The orographically induced cirrus across the eastern areas should erode after daybreak as the culprit disturbance moves east of the area and the upper trough lifts out. There is still some potential for gusty winds, especially this morning, with direction becoming more west to southwest helping to bring the warmer air back to the region.
Clear skies and calm winds prevail during the period given aforementioned surface ridging. Another tranquil weather day is in the forecast for Wednesday, with clear skies and highs reaching the lower to middle 70's across the region.
1229 PM EST Tue Nov 3 2020 Strong high pressure centered over the Gulf states will move off of the East Coast by Wednesday. From this center, a ridge of high pressure will extend back to the Texas coast and linger through the end of the week. By the weekend the ridge will slide northward and weaken, letting moisture increase over the Ohio Valley. The warming trend that began at the start of the week will continue as highs push into the lower to mid 60s.
255 PM EST Tue Nov 3 2020 As we head into the evening hours, upper ridging will become more zonal.
340 PM EST Tue Nov 3 2020 GOES water vapor channels highlight well a broad mid-upper level ridge extending over much of the western half of CONUS. Through the day, this eastward moving ridge has helped to push out a lingering surface boundary draped across the eastern forecast area and as a result, skies have begun clearing in the east. For the evening, as the sun continues to pivot across the sky toward the western horizon, the low level inversion will strengthen as surface temps cool, decoupling the lower boundary layer. We'll see temps falling into the 30s away from the lakeshores and the low 40s by the water. Given the similar setup and that daytime mixing exceeded guidance today, I hedged max temps on the high side, putting 60s in the west half and mid 50s in the east.
242 PM CST Tue Nov 3 2020 Northwest upper level flow and ridging over the western United States brings calm weather for our area. Strong southwesterly flow at the low levels continues to usher in warm air from the SW US. Late in the week, an upper level trough deepens into the Pacific NW. Model guidance hints a similar frontal structure to the cold front that passed through early last week which brought gloomy days and breezy conditions both ahead and behind the front along with multiple days of precipitation.
208 PM CST Tue Nov 3 2020 Tranquil and seasonably mild wx conditions prevail across the mid TN Valley this Tue, with a strong dome of high pressure layered from the srn Atlantic states into the much of the region. Current temps are mainly in the lower/mid 60s for most locations, and these values may climb another degree or two before max heating ends.
1232 PM EST Tue Nov 3 2020 Dry high pressure will linger through the end of the week. Heights rise through the period as a flat upper ridge builds in tonight and Wednesday. The weak lee trough this afternoon dissipates tonight as the center of high pressure moves into the area. Light W to SW winds east of the trough and N wind west of the trough become calm to light and variable overnight with clear skies. Expect light southerly winds to develop Wednesday as the high pressure center moves offshore.
This trough has caused some elevated winds in the southern Panhandle this afternoon. A little cooler tomorrow over today as GFS 700mb temperatures fall from +10C this afternoon to +6C Wednesday.
459 PM MST Tue Nov 3 2020 Moderate instability and moisture over our SW CWA has kept clouds in place through the day and limited sunshine and hence temperatures are a bit cooler than expected. Modest ascent coming from a wave that was a closed low to our West earlier today on the H500 hand analysis map. Overnight lows to be near the same trend though the dry air snow up high will keep the some of the high valleys and usual sinks on the cool side of normal.
High pressure in place across the Deep South and Mid- Atlantic will maintain another night of dry weather and seasonal temperatures. Overnight lows settle into the low 60s across the interior and into Volusia County, with normally cooler spots northwest of I-4 in the upper 50s. High pressure remains anchored across much of the Deep South and Mid-Atlantic states into Wednesday.
A pattern change to much cooler weather is forecast to occur by week's end, with a chance of rain and snow mainly over the Sierra. Water vapor images show the disturbance moving south towards the Baja coast allowing for ridge over the E Pac to build inland.
629 PM EST Tue Nov 3 2020 High pressure builds in starting this afternoon, bringing much warmer and drier weather for the rest of the week. By this evening, these will also be diminishing as ridge of high pressure settles in over NY/PA. Despite weak warm air advection at 850mb low temperatures will be from the mid 20s far east to the low and mid 30s along the I81 corridor and west. Wednesday the low level flow shifts to southwest and increases while aloft heights build as a broad ridge moves east. Models continue to depict with good agreement, that not only will the high pressure to our south persist; it will actually build further north to sit directly over our region this weekend.
/NEW/ Update: No significant changes were made with the evening update as the region remains under the influence of high pressure. Highs will be slightly warmer with a few areas warming to near 80 degrees. Temperatures tomorrow are expected to be slightly warmer than they were today as the southwesterly winds pick up during the afternoon. Slight compressional warming will allow for more locations to climb into the lower 80s.
849 PM CST Tue Nov 3 2020 A forecast update is in place for cooler lows tonight using a blend of the guidance plus bias correction. Given the lows in the upper 20s in some areas Tuesday morning, the forecast update attempts to capture the potential cooling overnight using the coolest guidance available.
544 PM EST Tue Nov 3 2020 GOES water vapor channels highlight well a broad mid-upper level ridge extending over much of the western half of CONUS. Through the day, this eastward moving ridge has helped to push out a lingering surface boundary draped across the eastern forecast area and as a result, skies have begun clearing in the east. For the evening, as the sun continues to pivot across the sky toward the western horizon, the low level inversion will strengthen as surface temps cool, decoupling the lower boundary layer. We'll see temps falling into the 30s away from the lakeshores and the low 40s by the water. Given the similar setup and that daytime mixing exceeded guidance today, I hedged max temps on the high side, putting 60s in the west half and mid 50s in the east.
558 PM CST Tue Nov 3 2020 Updated for 00Z aviation discussion 00Z TAF discussion: High pressure continues to dominate the regions. Tonight and Wednesday: High pressure at the surface continues to slide east of the region through the short term period. This, while ridging aloft steadily increases from the west. Then Wednesday afternoon, highs will top out in the low and middle 70s under sunny skies. /19/ Wednesday night through Tuesday: Come Wednesday evening a >1028mb high will be centered just off the mid Atlantic seaboard and ridging back across the Gulf coast states.
/issued 211 PM CST Tue Nov 3 2020/ SHORT TERM (Now through Wednesday Night): 500mb ridging centered overhead will continue to provide strong subsidence across the area through the period. At the surface, high pressure across the northern Gulf coast this afternoon will gradually move eastward off the Mid- Atlantic coast by Wednesday night. Highs on Wednesday will reach the low 80s to mid 80s at most inland areas and the mid 70s along the coast.
623 PM EST Tue Nov 3 2020 Canadian high pressure will continue to provide cool, dry air through Wednesday. High pressure overhead is the dominant feature for the next 36 hours with dry weather and clear skies. With light wind and clear skies associated with the high pressure system, good radiational cooling is expected again tonight with some patchy frost in some locations, mainly inland, although not as widespread as last night. Temperatures will warm closer to normal for both highs in the 70s and lows in the 50s Wednesday & Wednesday night as the high pressure influence continues.
505 PM CST Tue Nov 3 2020 After a chilly start the day has warmed nicely with temperatures reaching into the low 70s by early afternoon. A mid-level ridge stretching across the central CONUS and a parched atmosphere will continue to keep conditions mostly clear and dry into the weekend.
Northwest flow will develop behind the departing trough on Wednesday, with a very weak cool front passing through. Despite the passage of this cool front, Wednesday also looks very warm, with highs in the mid 70s along the urban corridor and upper 70s in the far east, with cooler temperatures across the higher terrain.
522 PM CST Tue Nov 3 2020 Unseasonably warm conditions were observed over the region today in response to an upper level ridge of high pressure that was translating across the nations midsection. Mild and quiet weather is expected tonight with overnight lows ranging from the middle 40s to the low 50s.
Tranquil and seasonably mild wx conditions prevail across the mid TN Valley this Tue, with a strong dome of high pressure layered from the srn Atlantic states into the much of the region. Current temps are mainly in the lower/mid 60s for most locations, and these values may climb another degree or two before max heating ends.
828 PM EST Tue Nov 3 2020 Clear skies at this time with large high pressure ridge dominating the southeast U. The high will move east-northeast through Wednesday morning with low level flow becoming more easterly and ushering some low level moisture to a very dry airmass. Strong high pressure will be north northeast of the region this period. This pattern will lead to an increasingly moist and warmer onshore flow.
As we head into the evening hours, upper ridging will become more zonal.
A ridge over the western Gulf of Mexico will continue to provide benign weather to our neck of the woods in the short-term with prevailing southerly winds and dry weather.
608 PM EST Tue Nov 3 2020 Warmer temperatures will continue to arrive through the upcoming week with highs in the 60s and eventually even some 70s heading towards the weekend.
929 PM EST Tue Nov 3 2020 Another clear, quiet night with high pressure in control. As we head into the evening hours, upper ridging will become more zonal.
851 PM EST Tue Nov 3 2020 High pressure will build across the southeastern US tonight, then migrate offshore for the remainder of the week. High pressure will continue to build over the Appalachians, which should lead to ideal conditions for radiational cooling. Min temps will range from the upper 20s and lower 30s in the colder valleys west of the Blue Ridge Mountains, to the middle 40s in downtown Washington and Baltimore.
419 PM MST Tue Nov 3 2020 Current surface map places weak trof over the eastern Dakotas.
/issued 257 PM EDT Wed Sep 1 2021/ Showers and thunderstorms continue across the region this afternoon as a trough trailing the remnants of Ida over the northern Gulf region and high pressure over the SW Atlantic are responsible for deep, moist W/SW flow across the state. A trough of low pressure trailing the remnants of Ida continues drifting south through the eastern Gulf of Mexico through Thursday with breezy west to southwest winds and numerous to widespread showers and thunderstorms.
Models show a weak upper trough push across the CWA tonight into Thursday morning. The upper ridge builds back in by day's end. The low level winds have a downsloping component to them a good part of tonight, with mainly upslope on Thursday. For temperatures, Thursday's highs are 3-56 C cooler than today's highs.
Overnight temps will drop to the lowest we have felt since early August.
