614 AM EST Tue Nov 3 2020 Areas of frost are possible this morning with 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.
346 AM CST Tue Nov 3 2020 As of 09Z Tuesday morning, midlevel ridging continues across the northwest US with troughing in the east. At the surface, a modest WAA pattern has taken shape with low-level ridging progressing east of the region.
425 AM MST Tue Nov 3 2020 Overnight GOES WV/IR imagery depicted a upper ridge axis from the southern Great Plains to the northern Rockies. High pressure centers were located along the ID/WY border and over western CO. 2 AM temperatures ranged from the lower 30s to lower 50s. The upper ridge axis to the west will finally progress to the east and flatten today and tonight. Gusty west winds of 25 to 35 mph will continue over the higher terrain of southeast WY.
Broad ridging will continue to take hold across the western half of the U. Through Wednesday, near zonal flow will set up across the nation, a weak trough will skirt the plains and Midwest, but will only support the continued highs in the upper 60s and 70s. We'll begin to see a pattern change through the end of the week, with a stout 500mb trough digging into the Pacific Northwest.
439 AM EST Tue Nov 3 2020 Drier and cooler high pressure will continue across the area, though with conditions moderating in the gusty NE flow.
An upper ridge overhead will shift to the east of the forecast area later today with slight cyclonic curvature moving over the region tonight as an upper short wave trough moves across the 4- corners region. The shifting of the ridge axis will allow for some cirrus to move across today, while at the surface tightening of the surface pressure gradient again today will result in a period of modestly breezy south to southwest winds. Finally, slight increase in 1000-500 mb thickness values point to temperatures a few degrees warmer than yesterday and in line with the increase seen in MOS guidance.
Upper level ridge remains in place today, and slides east over the area through the day and tonight.
After a chilly start to the day, high temperatures will range from the lower to upper 60s this afternoon.
640 AM 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.
In the upper levels, as a trough pushes eastward out of New England, our northwest cooler flow into Alabama transitions to a weaker zonal flow as a large upper ridge expands from Texas into Mexico and the Gulf Coast.
Upper level ridging will be in place over the region through much of the day today, with the flow becoming more zonal tonight and Wednesday. At the surface, a low pressure trough has set up from south central Canada to western Texas, with little movement expected today and tonight. This trough will slide slightly eastward on Wednesday. The period starts out dry with well above average temperatures as a ridge remains over the southwest CONUS.
The flow will become more zonal with some weak ridging trying to build into the area toward the end of the week. Temperatures have fallen into the lower to middle 30s across much of the Midlands and CSRA. H5 heights will continue to rise through the day and high pressure will dominate the weather across the region through the day and into tonight. Expect another chilly night with good radiational conditions as high pressure dominates the region. Cooler and drier air will enter the region through the period.
As of 09Z Tuesday morning, midlevel ridging continues across the northwest US with troughing in the east. At the surface, a modest WAA pattern has taken shape with low-level ridging progressing east of the region.
Early morning temperatures sitting in the lower to mid 40's across atleast 2/3rds of the CWA. Some upper 30's showing up early this morning across the Florida Parishes and coastal MS - more specifically across traditionally cooler drainage areas around the Pearl River/Pascagoula Basin. A brief synoptic overview across the region shows a progressive NW to SE flow upstream of a coastal Atlantic trough. We will rebound nicely later today with highs in the lower 70's and an all-around gorgeous day. Maybe a few degrees warmer, but generally have pulled overnight lows below suggested blended guidance with focus across drainage areas from the northshore east across the MS coast.
An upper level ridge over the Rockies moving east will bring higher temperatures and dry weather for the remainder of the work week. The ridge flattens to become more zonal near the end of the week preceding a deepening upper level trough, but above average temperatures and dry conditions are still expected during this period. The trough is expected to extend from the Pacific Northwest down to the southwest and initiate a low pressure system over Colorado.
630 AM EST Tue Nov 3 2020 High pressure will remain in control of the weather for most of the week. Despite the cloud cover and wind speeds around 5kts, many locations have still managed to drop into the lower 30s this morning as of 08Z. Highs today will be noticeably warmer than those seen yesterday as the airmass begins to modify, with afternoon temps climbing into the lower 60s. Lows tonight will also be a bit warmer, generally in the upper 30s to around 40.
) An anomalously strong ridge over the central CONUS today will focus the northern jet stream into southern Canada through the remainder of the week as broad mid-level zonal flow becomes the dominate feature of the Great Lakes region. While surface temps based on 925 hPa climatology indicate highs in the upper 60s today, the low mixing depths may place the 925 hPa layer within the inversion, thus making use of this climatology impractical.
As this trough develops, the pressure gradient tightens and will result in breezy SW/S winds today.
Light winds becoming s around 10kts mid morning to early afternoon as lee trof remains w of TX/NM stateline. /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.
At the surface, a leeside trof will reside across eastern CO and eastern NM today, then slide slowly east into our region on Wednesday. Have continued to lean on the warmer side of MOS guidance, especially on max temperatures, given the overall synoptic and surface patterns today through Wednesday.
A few thunderstorms will persist over southern Nevada and northwest Arizona into this afternoon as a weak low pressure area lifts northeast.
635 AM CST Tue Nov 3 2020 Morning temperatures have remains mild in the 40s especially along and west of the RRV escarpment with lower temps near freezing mainly in valley.
except for south Florida which is currently in the lower 70s. Through mid-week high pressure both at the surface and aloft will dominate the weather pattern across the southern tier states.
941 AM 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.
Although maxT will be below average for early November, a diminishing wind will make it feel warmer than yesterday. Clear skies, light winds and decoupled boundary layer should allow for the lowest min temps (low-mid 30s) tonight to occur in the central and eastern valleys. Meanwhile, a southwest breeze over the western high terrain should provide some of the warmest overnight readings (low 40s) across the ridgetops along the Allegheny Front.
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 imagery shows the weak upper low that produced showers and thunderstorms over Nevada now lifting slowly to the northeast this morning.
Strong radiational cooling was occurring where winds were clam, resulting in rapid temperature drops into the lower 30s. Today and Tonight: Considerably warmer today as southwest flow ushers in substantial low level WAA (850 mb temperatures jumping 6 to 8 degrees C from yesterday) and heights remain anomalously positive. High clouds should be on the increase tonight as a weak upper level trough slides out of the Rockies. Temperatures should dip into the lower 40s by sunrise Wednesday.
VFR through the period as deep ridging continues to strengthen across the area. An upper trough axis continues ejecting eastward over Ontario and the extreme northeast CONUS, paving the way for deep nwly flow aloft across much of the central/southeast United States. Likewise, confluent flow over the Southern Appalachians will further reinforce surface ridging across the I20 corridor, eventually advecting northeast into the TN Valley Tuesday evening. Closer to home, current conditions favor ample radiational cooling with most rural obs at or below freezing, while heat island effects continue to hold urban areas in the mid 30s. High pressure to the south will favor weak sly waa while deep dry air suggests sunny skies. Tonight, calm/cool conditions will prevail yet again amidst the ridge center settling nearly overhead.
Tonight, with southerly flow increasing dew points, overnight lows will be a few degrees warmer than previous nights. Wednesday will be a repeat of fair weather under high pressure influence.
557 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.
/issued 439 AM EST Tue Nov 3 2020/ Drier and cooler high pressure will continue across the area, though with conditions moderating in the gusty NE flow.
VFR conditions expected through the period as high pressure remains overhead. and in the low 50s along the coast. High pressure overhead and dry air will keep skies clear today and allow temperatures to warm to around 80 over the region. Quiet weather continues Wednesday with slightly higher humidity and warmer temperatures into the lower 80s.
It's another chilly morning across Middle TN as high pressure dominates the region.
(Today and tonight) An upper level ridge will start over the area today, and move just east of the region by tonight as an upper level low moves east into UT by late Tuesday night. With the ridge over the area, mostly sunny skies, and southerly winds, temperatures should be a few degrees warmer with highs in the mid 70s to around 80 degrees. Lows tonight will mainly be in the lower 40s.
541 AM CST Tue Nov 3 2020 Dry high pressure over the region will maintain VFR, while winds remain light from the northeast. except for south Florida which is currently in the lower 70s. Through mid-week high pressure both at the surface and aloft will dominate the weather pattern across the southern tier states.
956 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.
616 AM EST Tue Nov 3 2020 An elevated warm front tracking through the Central Great Lakes this morning will bring in some mid/high clouds today, otherwise clear skies tonight. Ongoing weak warm air advection underway within this pattern only strengthens with time, anchored by increasing southwest flow across the lowest 3k ft.
430 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.
and Wednesday Quiet weather and well above normal temperatures are expected through the middle part of the week as an upper level ridge builds across the western Great Lakes region.
Outlook is for warmer temps with more high clouds and a. However, the high pressure is already slipping away to the east Monroe and Alexandria rounding up the 1028mb contour points now with a lingering center over LA/MS by 15Z. It will be 1026mb by mid afternoon over AL with a falling barometer and S/SW return flow boosting the mercury back to average on the high end.
927 AM EST Tue Nov 3 2020 Dry high pressure will linger through the end of the week. There will be some gusty NW winds across the mountains, mainly at the higher elevations with lower wind speeds in the valleys. Otherwise, broad upper trofing will continue to lift NE of the region and farther offshore as heights gradually recover and broad upper ridging spreads farther eastward. At the sfc, robust, dry high pressure will remain over the region thru the period and will slowly shift east and then northeast later tonight and tomorrow. With the high in place, we can expect another day of mostly clear skies and light winds from the W and SW. Lows early Wed should remain well-above freezing but still about a category below normal.
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.
and in the low 50s along the coast. High pressure overhead and dry air will keep skies clear today and allow temperatures to warm to around 80 over the region. Quiet weather continues Wednesday with slightly higher humidity and warmer temperatures into the lower 80s.
250 AM MST Tue Nov 3 2020 Overnight GOES WV/IR imagery depicted a upper ridge axis from the southern Great Plains to the northern Rockies. High pressure centers were located along the ID/WY border and over western CO. 2 AM temperatures ranged from the lower 30s to lower 50s. The upper ridge axis to the west will finally progress to the east and flatten today and tonight. Gusty west winds of 25 to 35 mph will continue over the higher terrain of southeast WY.
However, the high pressure is already slipping away to the east Monroe and Alexandria rounding up the 1028mb contour points now with a lingering center over LA/MS by 15Z. It will be 1026mb by mid afternoon over AL with a falling barometer and S/SW return flow boosting the mercury back to average on the high end.
Upper heights will rise today as the East Coast trof departs, giving way to zonal flow.
830 AM EST Tue Nov 3 2020 High pressure builds into the area today and will settle along the coast on Wednesday.
920 AM 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.
340 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.
513 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.

Temperatures are running 5 to 15 degrees warmer at 10 AM CST this morning than at this time yesterday. Upper level ridging will be in place over the region through much of the day today, with the flow becoming more zonal tonight and Wednesday. At the surface, a low pressure trough has set up from south central Canada to western Texas, with little movement expected today and tonight. This trough will slide slightly eastward on Wednesday. The period starts out dry with well above average temperatures as a ridge remains over the southwest CONUS.
Low temperatures tonight will remain fairly cold in the upper 30s to mid 40s, but should be at least a few degrees warmer than last night.
1241 PM CST Tue Nov 3 2020 An upper ridge axis currently over the Rocky Mountain region will flatten out across the Northern and Central Plains today. Highs today mostly in the upper 70s with 80 or slightly warmer southwest into central NE. Looks to be only a degree or two cooler Wednesday.
Issued by National Weather Service State College PA 322 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.
A large area of high pressure covers much of the southeast U. Not much change is expected in the weather pattern for the next few days as high pressure remains over much of the eastern U. Temperatures tonight will be milder than the past couple of evenings with lows Wednesday morning in the low to mid 40s. Wednesday will see temperatures a few degrees warmer than today with highs in the lower 70s.
Issued by National Weather Service Lubbock TX 1145 AM CST Tue Nov 3 2020 (Today and tonight) An upper level ridge will start over the area today, and move just east of the region by tonight as an upper level low moves east into UT by late Tuesday night. With the ridge over the area, mostly sunny skies, and southerly winds, temperatures should be a few degrees warmer with highs in the mid 70s to around 80 degrees. Lows tonight will mainly be in the lower 40s.
222 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.
Overnight GOES WV/IR imagery depicted a upper ridge axis from the southern Great Plains to the northern Rockies. High pressure centers were located along the ID/WY border and over western CO. 2 AM temperatures ranged from the lower 30s to lower 50s. The upper ridge axis to the west will finally progress to the east and flatten today and tonight. Gusty west winds of 25 to 35 mph will continue over the higher terrain of southeast WY.
Broad upper ridging across most of the central CONUS today. West to southwesterly winds will continue throughout the period, and there should be plenty of sunshine for warmer than average temperatures during the day. Went on the higher side of guidance for tomorrow's highs, with several spots in southeastern ND still getting into the low 70s even with a bit more cloud cover than today. As this happens big upper low over desert SW rolls to the north and east, albeit slowly. Transition to snow should take a while with warmer temps persisting into and through the day on Sun. Much colder air slated to move back in behind the sharp trough Mon and Tue as 850 mb temps plummet below -10 C.
131 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.
156 PM MST Tue Nov 3 2020 Current surface map places weak trof over the eastern Dakotas.
1259 PM EST Tue Nov 3 2020 High pressure centered over the southeastern US will ridge into the area through tonight.
1052 AM EST Tue Nov 3 2020 A cooler morning across east central Florida on this first Tuesday of November.
1252 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.
