957 PM MST Mon Nov 16 2020 19Z Water vapor imagery and RAP analysis indicated CWA in broad northwesterly flow aloft with large H5 ridge to the west of the area, centered over the northern Rockies. Weather across the Tri State area will be quiet through the period as aforementioned H5 ridge amplifies and moves over the region. Temperatures will continue to warm and based on how fast todays temperatures reached or exceeded the expected values today, think the warmer solutions pushing into the lower 70s looks reasonable. Strong lee trough will develop Tuesday morning leading to increased southerly winds into the afternoon.
315 AM EST Tue Nov 17 2020 A strong but dry cold front will sweep across the area this afternoon. Strong, cool and dry Canadian high pressure will follow for the mid-week period, with the high's center settling across the region by the end of the week.
923 PM CST Mon Nov 16 2020 Skies will be mostly clear tonight with the winds shifting from the southwest to the northwest overnight as a cold front moves through the region. High temperatures will be cooler on Tuesday, in the 40s.
With the high clouds, it has been hard to judge the movement of the fog, but it still seems to be sagging south and east. An upper ridge over the northern/Canadian Rockies tonight will translate across the northern plains and shift east of the CWA tomorrow morning, when the area transitions to SW flow aloft.
Fog has been the other interesting development with the low stratus bank to the northeast hitting the ground in Sheridan county. As this trough lifts northward, winds should shift to a more southerly or southeasterly direction. Assuming no (or little) fog tomorrow, temperatures should warm up nicely and take a swipe at the snow on the ground, and many non- valley locations should stay above freezing tomorrow night. Wednesday should be warmer (again, assuming little/no fog in the morning), but the coverage of fog and low clouds will be the determining factor on where exactly we land.
230 AM EST Tue Nov 17 2020 A dry cold front will move through the area today, bringing substantially cooler and windy conditions.
245 AM CST Tue Nov 17 2020 Upper ridging is over the region with an upper trough just off the west coast. The upper ridge will become more centered over the central part of the country by this evening. Surface winds will mostly be out of the south to southeast this afternoon with high temperatures a little cooler than yesterday. Temperatures are expected to be a little warmer on Wednesday than those today; otherwise, conditions will be very similar.
958 PM CST Mon Nov 16 2020 At 130 PM, low pressure was located over western Wisconsin, with an area of snow located to the northeast of the low across north- central into northeast Wisconsin. As low pressure pushes farther southeast this afternoon, snow should taper off quickly over north-central Wisconsin. Winds will continue to be gusty across northeast Iowa and southeast Minnesota in the tight gradient behind the departing low-pressure system. High pressure will begin to nudge into the area later this evening, very gradually diminishing the cloud cover and allowing gusty west-northwest winds to die down. This high pressure remains in control for Tuesday, with a dry but cool day expected.
/NF/ Another clear night with a calm wind will lead to cooler than normal temperatures by morning. On Tuesday, high pressure ridging will strengthen over the area once again, from a high centered over the Ohio Valley. /15/ Quiet weather will prevail through the week as the region will remain under high pressure at the surface and upper ridging aloft.
A dry cold front will move through tonight with the only noticable feature is a shift in winds. Overnight lows will range from the middle 30s for the Plateau to near 40 in the warmer heat island of Nashville. Highs tomorrow will be a bit cooler than today /remember cold front passage/ with near 40 for the Upper Cumberland Plateau to middle to upper 50s across the south near the Alabama state line.
117 AM EST Tues Nov 17 2020 A dry cold front will move through the area on Tuesday, bringing substantially cooler and windy conditions.
and again to near 30 mph across the eastern half of the area Wednesday as a trough of low pressure approaches from the northwest.
533 AM CST Tue Nov 17 2020 Calm weather conditions on tap for today with partly sunny skies and highs in the lower 30s. A breif warm up is expected later this week with our southern portions of the CWA potentially climbing into the lower 50s. Northwesterly flow remains aloft over the Northland as an upper level ridge increases in amplitude over the Intermountain West. At the surface a high pressure dominates the region with partly sunny skies prevailing across the region. Look for temperatures to stay below freezing today.
407 AM EST Tue Nov 17 2020 Expect dry weather and brisk winds today as high pressure builds behind a cold front.
(Today and tonight) The upper level ridge of high pressure across across the middle of the country will bring plenty of sunshine today to West Central Texas.
High pressure continues to dominate the weather through the period with mostly clear skies and light winds.
422 AM MST Tue Nov 17 2020 The midlevel ridge is beginning to pass over the region and some high clouds have formed on the edge of the moisture confined to the north. The ridge axis is expected to move overhead this morning with weak southwest flow developing in it's wake. A deepening low pressure over the Pacific Northwest will push the ridge off the east and allow southwest flow to become established and remain in place through the week.
On our marine district, winds are northeast near 15 knots, except near 20 knots on the waters west of Seven Mile Bridge to beyond Dry Tortugas. A weak cold front draped across South Florida and the adjacent Atlantic and Gulf waters this morning will sag southward and into our area later today and stall over the Florida Straits tonight, before becoming diffuse. Meanwhile, a formidable area of high pressure over the entire east central United States will strengthen and expand into the eastern United States, and down the Sunshine State while bridging the aforementioned front.
/issued 245 AM CST Tue Nov 17 2020/ Upper ridging is over the region with an upper trough just off the west coast. The upper ridge will become more centered over the central part of the country by this evening. Surface winds will mostly be out of the south to southeast this afternoon with high temperatures a little cooler than yesterday. Temperatures are expected to be a little warmer on Wednesday than those today; otherwise, conditions will be very similar.
VFR conditions are expected to prevail over the next 24 hours with high pressure in control and shallow boundary layer moisture. /issued 331 AM CST Tue Nov 17 2020/ SHORT TERM (Now through Tuesday): Very mild, and pleasant weather conditions are expected over the next couple of days, as mid level ridging remains centered over South Texas. This ridging pattern, along with a shallow moist surface layer, will keep mentionable PoPs out of the short term. Afternoon temperatures will reach the lower 80s today, and warm up slighlty into the mid 80s on Wednesday. Tonight will be cool, with temperatures ranging from the mid 50s in the northern ranchlands, to near 60 across the lower RGV.
345 AM CST Tue Nov 17 2020 Another cool start underway across the area this morning, with temperatures running generally in the lower/mid 40s away from the immediate coast. More robust warming (especially with overnight temperatures) is expected late week and into the weekend as the low level flow takes on an increasing onshore component.
815 AM EST Tue Nov 17 2020 A crossing cold front will usher scattered rain to snow showers to region today with accumulating snow along and north of Interstate 80 corridor and in the ridges tonight. Rain and snow showers are being observed ahead of the cold front where warmer temperature is evident; though a quick transition to snow showers is occuring as cold advection supports steepening lapse rates. Overall, snow totals by Wednesday morning will be highest in the aforementioned counties and in the ridges. Any remaining snow shower activity will come to an end Wednesday morning as ridging moves in from te west. Dry conditions and warmer temperatures will then prevail the remainder of the week with high pressure in control.
Mid and high clouds are increasing across NorCal early this morning as the trough approaches. Significant snowfall is forecast across the higher mountain elevations later today into Wednesday with several feet of accumulation expected near the higher northern Sierra passes and across the peaks.
334 AM MST Tue Nov 17 2020 08z surface analysis had low over north central MT with warm front into western NE. Water vapour had upper ridge building from the Rockies into the northern plains. Today, thermal ridge builds into the CWA with highs 10-15F degrees above normal per warm front moving eastward. Tonight ahead of lee trough, 3-4mb/3hr pressure falls develop over western ND into central SD. Wednesday, thermal ridge peaks over the CWA.
400 AM MST Tue Nov 17 2020 High pressure ridge axis will be centered over the forecast area today before shifting east allowing more of a zonal flow aloft for Wednesday.
Axis of mid/upper level trough will shift offshore the eastern U. Breezy northerly winds behind this boundary today will usher in a drier and cooler airmass, with highs in the mid to upper 70s across the area with sunny to mostly sunny skies expected. Cooler temperatures expected into tonight, with lows in the low to mid 50s over the interior. VFR conditions today and into tonight as breezy northerly winds usher in a cooler/drier airmass. Breezy northerly winds behind cool front south of the area will usher in a drier and cooler airmass today, with RH values falling into the 30s this afternoon over the interior from the I-4 corridor westward.
529 AM CST Tue Nov 17 2020 High pressure will keep skies mainly clear during the coming TAF period. High pressure continues to be the main influence over South Central Texas tonight. High pressure will remain in place through this period.
/issued 345 AM CST Tue Nov 17 2020/ Another cool start underway across the area this morning, with temperatures running generally in the lower/mid 40s away from the immediate coast. More robust warming (especially with overnight temperatures) is expected late week and into the weekend as the low level flow takes on an increasing onshore component.
519 AM CST Tue Nov 17 2020 Upper level high pressure will build overhead later today. /issued 330 AM CST Tue Nov 17 2020/ Upper level high pressure sharpening across the southwestern U. and Great Basin this morning will shift across the Rockies into the high plains this afternoon, then edge east tonight.
High pressure advancing from the mid-Mississippi to Wabash Valley today will provide us with brisk northwest breezes and cool temperatures. Tonight the high will strengthen and move right overhead with light winds and mostly clear skies. Went on the cool side of guidance because of this, and took our eastern sheltered valleys down into the lower 20s. After a cold start Wednesday morning, high temperatures in the afternoon will remain a bit below normal reaching the low/mid 50s with a few upper 40s across the Bluegrass.
944 AM EST Tue Nov 17 2020 Upper troughing in place over the Ohio Valley will gradually exit off to the east today, replaced by ridging from the west. High pressure advancing from the mid-Mississippi to Wabash Valley today will provide us with brisk northwest breezes and cool temperatures. Tonight the high will strengthen and move right overhead with light winds and mostly clear skies. Went on the cool side of guidance because of this, and took our eastern sheltered valleys down into the lower 20s. After a cold start Wednesday morning, high temperatures in the afternoon will remain a bit below normal reaching the low/mid 50s with a few upper 40s across the Bluegrass.
SHORT TERM (Now through Tuesday): Very mild, and pleasant weather conditions are expected over the next couple of days, as mid level ridging remains centered over South Texas. This ridging pattern, along with a shallow moist surface layer, will keep mentionable PoPs out of the short term. Afternoon temperatures will reach the lower 80s today, and warm up slighlty into the mid 80s on Wednesday. Tonight will be cool, with temperatures ranging from the mid 50s in the northern ranchlands, to near 60 across the lower RGV.
524 AM CST Tue Nov 17 2020 Warmer air will push into the region during the short term. H85 temps will rise by 10 to 12C as upper ridging builds in. A front will begin to move through the Dakotas late in the period as the low moves off the Hills.
A weak cold front currently sitting just to the north will slip south of the mid-state this morning and bring us a shot of cooler dry air. Aloft an upper ridge starts to build early Wed as well. Upper ridging and SFC/LL high pressure hold right on into late weekend as later on Sun a cold front ahead of an approaching trough moves into the MS river valley. Behind this upper trough, another fast mover is right on its heels, and it will move over the area Tues night. It will be accompanied by a weak SFC/LL trough axis and another shot of moisture so that will keep at least a chance for showers running Sun night through Tue.
304 AM CST Tue Nov 17 2020 A cold front will move through the Mid-South over the next couple of hours. Temperatures will be cooler today with highs expected to be in the mid 50s to around 60 degrees across much of the area. These locations will likely still see highs in the lower to mid 60s. High pressure will build over the Mid-South tonight and will remain over the region through Wednesday Night.
Today Through Wednesday Night An amplifying upper ridge over the Rockies today will move into the Plains tonight and into the Great Lakes Wednesday. Lows tonight will be in the lower 30s to lower 40s and in the 40s Wednesday night.
531 AM CST Tue Nov 17 2020 Aside from a bit of stratus along the James River Valley, current satellite imagery reveals clear skies and quiet conditions across our area, with latest observations showing temperatures hovering in the low 20s thanks to efficient radiational cooling. Otherwise, expect dry conditions to prevail today as an amplified upper level ridge moves overhead the region, with highs ranging in the 50s across south central SD to near 40 degrees in areas east of I-29.
/issued 304 AM CST Tue Nov 17 2020/ A cold front will move through the Mid-South over the next couple of hours. Temperatures will be cooler today with highs expected to be in the mid 50s to around 60 degrees across much of the area. These locations will likely still see highs in the lower to mid 60s. High pressure will build over the Mid-South tonight and will remain over the region through Wednesday Night.
648 AM EST Tue Nov 17 2020 A cold front will track from the Ohio Valley to off the southeast coast by the end of the day. This front will lead in colder air and high pressure.
557 AM EST Tue Nov 17 2020 A strong but dry cold front will sweep across the area this afternoon. Strong, cool and dry Canadian high pressure will follow for the mid-week period, with the high's center settling across the region by the end of the week.
419 AM MST Tue Nov 17 2020 Warm & dry conditions can be expected today across a large portion of southeast Wyoming and the western Nebraska Panhandle with short wave ridging overhead. Winds are expected to increase near the Arlington/ Elk Mountain areas by early this evening w/ surface pressure falls spreading across the central & northern high plains, in advance of deep upper-level troughing over the western US.
216 AM MST Tue Nov 17 2020 08z surface analysis had low over north central MT with warm front into western NE. Water vapour had upper ridge building from the Rockies into the northern plains. Today, thermal ridge builds into the CWA with highs 10-15F degrees above normal per warm front moving eastward. Tonight ahead of lee trough, 3-4mb/3hr pressure falls develop over western ND into central SD. Wednesday, thermal ridge peaks over the CWA.
526 AM CST Tue Nov 17 2020 High pressure and clear skies with VFR conditions will be the rule across the area. Today Through Wednesday Night An amplifying upper ridge over the Rockies today will move into the Plains tonight and into the Great Lakes Wednesday. Lows tonight will be in the lower 30s to lower 40s and in the 40s Wednesday night.
321 AM MST Tue Nov 17 2020 The midlevel ridge is beginning to pass over the region and some high clouds have formed on the edge of the moisture confined to the north. The ridge axis is expected to move overhead this morning with weak southwest flow developing in it's wake. A deepening low pressure over the Pacific Northwest will push the ridge off the east and allow southwest flow to become established and remain in place through the week.
Well above normal temperatures are expected once again today as we remain under the influence of strong high pressure. Temperatures are expected to return closer to normal this weekend as an area of low pressure moves through the region. Well above normal temperatures have once again become our main weather headline thanks to strong high pressure over the region.
Warmer temperatures are expected today and again on Wednesday, as the warm front tracks through the area early this morning. Gusty winds will accompany the warmer temperatures tomorrow, with gusts up to 40 mph possible along the ridges of the Rocky Mountain Front, the Little Belt Mountains, and the southwestern mountains.
232 AM MST Tue Nov 17 2020 Upper ridge will be over Montana today which will bring some very warm air aloft for mid November. Better mixing on Wednesday will result in warmer surface temperatures even though the air aloft will be not as warm as today.
Fortunately the air mass was relatively moist with dew points in the lower teens, so that kept temperatures from falling off too much overnight. Skies will be mostly sunny, so did raise temperatures toward the high end of the blended guidance. Lows near 40 across southern MN decreasing to the lower 30s across central MN are likely Wednesday night.
Once the fog lifts, much of the Northern Rockies will be under a transient ridge of high pressure today. The ridge does not last long, though, as an upper-level closed system of low pressure spinning off the coast of Washington migrates north and east. The low pressure circulation will also send some Pacific moisture up from the southwest. Snow levels will drop behind the cold front, but not enough to bring snow down to the valley floors.
219 AM MST Tue Nov 17 2020 Warmer temperatures are expected today and again on Wednesday, as the warm front tracks through the area early this morning. Gusty winds will accompany the warmer temperatures tomorrow, with gusts up to 40 mph possible along the ridges of the Rocky Mountain Front, the Little Belt Mountains, and the southwestern mountains.
531 AM CST Tue Nov 17 2020 (Today and tonight) Upper ridge builds out across the Plains today with mild temperatures and another day with abundant sunshine. Winds will increase some today as pressure falls occur across the high Plains in advance of developing western trough. Winds will stay up some overnight and temperatures will remain several degrees warmer than the last several nights.
VFR conditions prevail with ENE winds that may become gusty at times this afternoon with high pressure in control, and a subsequently tighter pressure gradient.
520 AM CST Tue Nov 17 2020 Today will feel a bit cooler than yesterday as a weak backdoor cold front pushes through the area tonight. The northerly winds and cooler airmass will be more noticeable over norther central Missouri with highs in the upper 40s to lower 50s, but the KC Metro will feel the effects too with highs in the mid to upper 50s. This cool down will be brief as upper level ridging and strong southerly return flow in the low levels builds into the region Wednesday. This higher wind combined with lower relative humidity will increase fire danger along the KS/MO border and burning is not recommended. The higher winds will come with WAA though as our high temps get into the upper 60s with some pockets of 70s in NW Missouri.
Strong winds ahead of the approaching system will affect the high sierra, the West Side Hills and the Kern county mountains into Tuesday afternoon. Upper level clouds moving across central CA this morning ahead of an approaching trough off the California coast. Models show strong SW winds developing this afternoon over the higher elevations of the sierra before the arrival of moisture along a front. The associated cold front will sweep from North to South across the Central California interior on Tuesday evening into Wednesday morning.
639 AM EST Tue Nov 17 2020 Expect dry weather and brisk winds today as high pressure builds behind a cold front.
815 AM EST Tue Nov 17 2020 A dry cold front will move through the area today, bringing substantially cooler and windy conditions.
317 AM CST Tue Nov 17 2020 Aside from a bit of stratus along the James River Valley, current satellite imagery reveals clear skies and quiet conditions across our area, with latest observations showing temperatures hovering in the low 20s thanks to efficient radiational cooling. Otherwise, expect dry conditions to prevail today as an amplified upper level ridge moves overhead the region, with highs ranging in the 50s across south central SD to near 40 degrees in areas east of I-29.
620 AM EST Tue Nov 17 2020 A dry cold front will move through the area today, bringing substantially cooler and windy conditions.
Upper ridging, centered to the west of the CWA, can be seen in the cloud field on the IR satellite pictures at this time. This ridge is progged to push eastward across the CWA today, with weak zonal flow aloft tonight. The low level pressure and wind fields show lee troughing today and tonight. For temperatures, highs today look to be 1-4 C warmer than yesterday's highs. With this increase in flow, expect an increase in winds over the higher mountains and exposed east slopes.
523 AM CST Tue Nov 17 2020 (Today and tonight) The upper level ridge of high pressure across across the middle of the country will bring plenty of sunshine today to West Central Texas.
Post frontal clear/cool/dry regime continues across the local area as high pressure dominates the area. A slight moderation in temps expected today with highs in the low to mid 70s as upper ridge centered over Mexico expands across slightly over the northern Gulf Coast. A reinforcement of the continental airmass will occur late tonight into Wednesday morning as the ridge to the north lifts north, tracks east, then pushes back south again.
329 AM CST Tue Nov 17 2020 Calm weather conditions on tap for today with partly sunny skies and highs in the lower 30s. A breif warm up is expected later this week with our southern portions of the CWA potentially climbing into the lower 50s. Northwesterly flow remains aloft over the Northland as an upper level ridge increases in amplitude over the Intermountain West. At the surface a high pressure dominates the region with partly sunny skies prevailing across the region. Look for temperatures to stay below freezing today.
455 AM MST Tue Nov 17 2020 Warm & dry conditions can be expected today across a large portion of southeast Wyoming and the western Nebraska Panhandle with short wave ridging overhead. Winds are expected to increase near the Arlington/ Elk Mountain areas by early this evening w/ surface pressure falls spreading across the central & northern high plains, in advance of deep upper-level troughing over the western US.
314 AM MST Tue Nov 17 2020 Well above normal temperatures are expected once again today as we remain under the influence of strong high pressure. Temperatures are expected to return closer to normal this weekend as an area of low pressure moves through the region. Well above normal temperatures have once again become our main weather headline thanks to strong high pressure over the region.
