Despite the weakening storm intensity, scattered showers and storms are still expected to progress into outlook area this morning with the low-level jet focused over central KS and with decent isentropic lift present. As a result, high temperatures should be able to quickly rise into the low/mid 80s.
154 PM EDT SUN SEP 4 2016 Upper level ridge builds overhead and keeps the area dry for the next several days. then possible cold front approaches late in the week. however the heat and humidity will be on the rise as upper ridge over the Southeast U. Large upper ridge becomes entrenched over most of the Eastern U.
253 PM EDT SUN SEP 4 2016 An expansive area of high pressure will remain across New England and maintain the dry weather pattern through mid-week.
258 PM EDT SUN SEP 4 2016 An expansive area of high pressure will remain across New England and maintain the dry weather pattern through mid-week.
High pressure aloft and on the surface will remain in control of the weather pattern.
Also the latest 14z HRRR model was indicating convective development over this same area later this afternoon as the thermal trough moves overhead.
122 PM EDT SUN SEP 4 2016 High pressure at the surface and aloft will keep the weather quiet over the next couple of days with little clouds or wind. Then models indicate some good moisture return on the backside of the high. Cool morning temperatures will lead to afternoon readings reaching around 80 as high pressure loosens its grip slightly and the air mass continues to modify. This will lead to a repeat performance for Labor Day except for afternoon highs warming more firmly into the lower half of the 80s, all of this with low humidity and just a few shallow cumulus and wisps of cirrus. Current water vapor satellite imagery indicates a moderate surge of upper level height falls occuring along the west coast while the ridge continues to mature a rex block with Hermine from the Great Lakes eastward.
638 PM EDT SUN SEP 4 2016 Fair weather expected to continue through this week, as dry high pressure dominates. Upper trough will shift southward and through the southeastern states later tonight, but due the dry conditions through the atmosphere, precip is not expected. May see a few more mid or upper level clouds tonight with the trough as it pushes through. The trough axis will be off the southeastern coast by morning.
We are being influenced by high pressure at the sfc and ridging aloft. Highs today will be a couple of degrees warmer than yesterday and span the 80s. High pressure is in control and will be for the next 24 hours.
A cold low pressure system is beginning to influence western Montana and central Idaho this afternoon, as it has begun to swing through central Idaho. With freezing levels dropping with the approaching low, small hail will be possible with any thunderstorms that develop, along with heavy rain and lightning. While snow accumulations are most likely in the mountainous terrain, some slushy snow is possible down into the high valleys of southwest Montana, such as Butte, though any accumulations will likely me minimal at best.
357 PM MDT SUN SEP 4 2016 An energetic trough was progressing through the northern Great Basin this evening. A dry breezy SW flow will dominate elsewhere on Monday as the Great basin trough deepens.
1254 PM CDT SUN SEP 4 2016 We will be between two disturbances within southwest flow due to the synoptic trough to the west over the Great Basin. The low-level jet is helping to perpetuate the current convection, but it should continue on its way out this morning, and by afternoon, most locations should be dry in between perturbations. The next wave comes tonight as a cold front approaches from the northwest. Strengthening of the low- level jet tonight will aid in the production of storms and could lead to an MCS containing severe weather, especially in our northwest by late evening into the overnight.
230 PM PDT SUN SEP 4 2016 Much cooler air will filter into the region tonight behind a cold front.
Temperatures today have warmed into the lower 90s across the region and dewpoints are running in the lower to mid 70s. The summer pattern will continue through most of the week as an upper ridge will prevail over the region. This will result in highs in the 90s each day and overnight lows in the lower to mid 70s.
242 PM CDT SUN SEP 4 2016 The high resolution convective allowing models show another round of storms developing this afternoon. Temperatures will remain warm in the low 90s through mid week before cooling to the low 80s by the weekend.
330 PM CDT SUN SEP 4 2016 Temperatures continue to warm on the western periphery of a large high pressure system centered over the northeastern CONUS. Southeast flow will continue to turn to a more southerly direction late tonight increasing the low level warmth and humidity.
But surge of deeper moisture moving up the coast about to reach the Lower Rio Grande Valley at 35 knots. Another area of convection being monitored is moving into the Lower Rio Grande Valley at around 35 knots.
Nevertheless, a relatively cool day is upon us thanks to another cold front that moved through early this morning. This will be the coolest day in forecast however as the broad upper trough across the Western CONUS will begin to lift north over the next 24 hours.
With the large upper trough over the West, temperatures remain below average and generally range from the 60s in the mountains, to the mid 70s to mid 80s elsewhere at mid-afternoon. Warming returns to the region beginning Labor Day as ridging from the eastern Pacific extends into NorCal and mostly light northerly flow develops.
Breezy southerly winds helping push temps tin the lower and middle 80s with dewpoints near 70. Modest isentropic upglide resumes tonight over a 50kt south- southwest low level jet with moisture in the low-mid levels not very near saturation at any particular level. The low level jet and high dewpoints should keep lows in the lower 70s for the most part.
302 PM EDT SUN SEP 4 2016 Post Tropical Cyclone Hermine will continue to lift slowly northeast along the East Coast through late week as high pressure persists over the Southeastern States. Will hang on to a slight chance PoP through the evening NE sections/Outer Banks then indicate gradual clearing as weak high pressure continues to build over the area. High pressure surface and aloft will continue to exert it's influence on the area with partly cloudy skies and warm temperatures. Highs will be in the lower 80s.
548 PM EDT Sun Sep 4 2016 High pressure will maintain dry weather and warm temperatures through midweek. No major changes were needed for the afternoon update of the near term forecast as high pressure remains entrenched on the western flank of post-tropical storm Hermine. Mid/upper ridging with neutralized, then warm temperature advection between Hermine and a Rocky Mountain trough will support further temperature moderation.
138 PM EDT Sun Sep 4 2016 Dry conditions are forecast for the foreseeable future through at least mid-week as strong high pressure continues to dominate the North Country's weather. Clear skies and above normal temperatures are in store for the next several days, with any effects from post-tropical cyclone Hermine remaining well south of the area. I'm starting to feel like a broken record here writing discussion after discussion about high pressure, light winds, overnight valley fog and warming temperatures day after day after day. * Strong high pressure persists, no effects from Hermine. * Temps tonight/tomorrow a couple degrees warmer than last night/today. The ridge of high pressure at the surface and aloft will remain over the region through the period with fair and dry weather expected.
126 PM EDT SUN SEP 4 2016 High pressure will remain in place across the region through mid week. High pressure and dry conditions will be in place across the area today.
104 PM EDT Sun Sep 4 2016 High pressure will maintain dry weather and warm temperatures through midweek. No changes were needed for the afternoon update of the near term forecast as high pressure remains entrenched on the western flank of post-tropical storm Hermine. Mid/upper ridging with neutralized, then warm temperature advection between Hermine and a Rocky Mountain trough will support further temperature moderation.
An amplified pattern is in place with a strong trough through western states northwest of our area, bracketed by a very strong ridge south of the Gulf of Alaska upstream and a strong ridge over Southeastern states downstream.
339 PM PDT SUN SEP 4 2016 Cooler than normal conditions will continue for interior locations through Monday. (Tonight through Monday) Another beautiful day is in progress across Northwestern California, with just a few ridge-top cumulus developing along eastern Del Norte and Humboldt counties, and near the Yolla Bolly Mountains. As the trough continues to leave the region, mid-level heights will start to slowly increase tonight.
238 PM EDT Sun Sep 4 2016 Post Tropical Cyclone Hermine is positioned 300 miles east of Ocean City Maryland. High pressure will move over the region for much of the work week. A cold front will approach from the west towards weeks end. The low pressure area which was formerly Hermine looks a lot more like a mid latitude cylone than a tropical storm. from the upper 60s in the cities to the mid 50s in the Highlands.
406 PM CDT SUN SEP 4 2016 The Panhandles will remain in an area of SW flow aloft between mid-a upr lvl high center across the deep south and a trough w/ base digging into NV. H7 theta-e ridging across the wrn 3rd indicates bit of a monsoon connection there while low level SFC to H85 gulf moisture is more evident across the east (hence the mid-upr 60s dewpoints).
The higher instability is across western portions of the county warning area. The other concern is the low level wind shear later this evening as the low level jet kicks in.
A large trough of low pressure aloft is entrenched over the northern Rockies region which places northeast Montana in a steady moist SW flow aloft. Monday: The closed upper low center becomes an open wave and moves directly over northeast Montana.
257 PM EDT SUN SEP 4 2016 High pressure over the Lower Great Lakes will continue to gradually shift eastward over the next couple of days.
1022 AM EDT Tue Oct 4 2016 High pressure will build over the eastern United States through mid week. Otherwise, RAP soundings show dry air remaining in place today as inland high pressure wedge holds. High pressure will remain north of the area while tropical cyclone Matthew moves north from the Bahamas.
918 AM EDT Tue Oct 4 2016 High pressure will remain across the region through the end of the week. The high pressure ridge will remain over the area through the period. A filling upper level low will be over Cape Cod and will slowly fill as it move southeast into the north Atlantic. High pressure will continue to reign supreme through the short term with sunny skies, light winds and abv normal temperatures. Main question continues to center around the strength of the sub-tropical ridge and what impact that wl hv on the mvmnt of Matthew and this still rmns to be seen. Other than that, expect VFR through the period under high pressure.
1208 PM EDT Tue Oct 4 2016 High pressure will remain across the region through the end of the week. The high pressure ridge will remain over the area through the period. A filling upper level low will be over Cape Cod and will slowly fill as it move southeast into the north Atlantic. High pressure will continue to reign supreme through the short term with sunny skies, light winds and abv normal temperatures. Main question continues to center around the strength of the sub-tropical ridge and what impact that wl hv on the mvmnt of Matthew and this still rmns to be seen. Other than that, expect VFR through the period under high pressure.
Models show that we'll have a decrease in showers over the Rogue Valley this morning and afternoon, then showers fill in again tonight and Wednesday as an upper trough moves through. Upper troughing with a few fast-moving impulses will maintain clouds and the chance for rain across much of the forecast area through midweek.
The highest areal coverage of showers will likely occur from coastal se Ga across ne Fl. Inverted trough with numerous showers over the ne Fl waters this morning with strong high pressure building in from the north.
740 AM EDT TUE OCT 4 2016 High pressure positioned northeast of the area will be the main influence on our local weather through much of the week. One dissipating cold front will near northwest Ohio Wednesday night.
Otherwise expect the low driving the trowal to slowly lift northward through the day today, bringing precipitation with it. The biggest change was to warm temps just a bit across the east where dry slotting will allow a bit warmer airmass to push in from the south. However, little accumulation is expected as temperatures are expected to remain at or above freezing. The main band of wrap around precip will also lift north this evening as the upper low moves north into Saskatchewan.
634 AM CDT Tue Oct 4 2016 Vigorous upper trough ejecting into the Plains this morning is already forcing an extensive line of showers and thunderstorms from Texas into the Dakotas. Much of this activity will likely weaken later in the day as the low-level jet that is currently feeding it weakens. Convection will then likely regenerate along an advancing cold front across central and eastern KS later this afternoon as the primary upper trough approaches from the west. Cold front will lose much of its punch overnight as the main upper- level energy bypasses the region to the north. However, by late afternoon a warm frontal boundary will begin to organize and lift north toward into eastern KS and western/central MO.
746 AM EDT Tue Oct 4 2016 High pressure will build over the eastern United States through mid week. Slightly drier high pressure will continue to build in from the north while a broad trough lingers just off the coast. The deepest moisture will remain off the coast where the coastal trough will continue to spur scattered to numerous showers and tstms. High pressure will remain north of the area while tropical cyclone Matthew moves north from the Bahamas.
1001 AM EDT Tue Oct 4 2016 An upper level low, which has impacted our weather for several days, is finally exiting by sliding off the coast.
1240 PM EDT Tue Oct 4 2016 High pressure will bring dry conditions today with partly cloudy skies and high temperatures in the mid 70s.
Some mid and high level clouds may advect in during the afternoon ahead of approaching cold front. Water vapor loop reveals a shorter wave length ridge persisting over the Great Lakes with mesoanalysis showing much better anticyclonic flow at the surface compared to yesterday. Highs in the low 70s, several degrees warmer than yesterday, remain a reasonable expectation. The weather through late week will be moderated mainly by the evolution of the closed low over Montana that is presently anchoring the developing longwave trough over the western US.
Tranquil weather conditions exist across northern AL/southern TN this morning, provided by an amplified mid-level ridge which is currently shifting eastward across the region. Little change in this pattern is anticipated overnight, as models suggest that the deepening upstream trough will lift northeastward into the southern Canadian provinces -- maintaining a moderate southwest flow aloft over the TN valley. However -- as mentioned yesterday -- guidance from the GFS/GEM/UKMET and ECMWF is now in unanimous agreement that the Atlantic subtropical ridge will begin to build westward into the southeastern Atlantic coast/southern CONUS on Wednesday, as a trough near the coast of New England weakens and lifts east-northeastward.
An upper low over Vancouver Island will cause clouds and showers to increase over south-central Washington this afternoon.
905 AM EDT TUE OCT 4 2016 High pressure positioned northeast of the area will be the main influence on our local weather through much of the week. One dissipating cold front will near northwest Ohio Wednesday night.
Strongest gusts near 30kt after 20Z over northeast NM and the higher terrain.
741 AM EDT Tue Oct 4 2016 A ridge of high pressure will build over the region today and remain over the area through the end of the work week.

1147 AM EDT TUE OCT 4 2016 Hydro A large area of High Pressure over Quebec builds southeast today and Wednesday. Mid to upper level lift then spreads in during the day as a closed low settles in over North Dakota and becomes nearly stationary or drifts north in time.
846 AM EDT Tue Oct 4 2016 Building high pressure will maintain dry and warm weather for much of the week. Otherwise, high pressure will build in today, fog will dissipate, and mostly sunny skies will return.
1256 PM EDT Tue Oct 4 2016 High pressure will build over the eastern United States through mid week. High pressure will remain north of the area while tropical cyclone Matthew moves north from the Bahamas.
1143 AM EDT Tue Oct 4 2016 A ridge of high pressure will build over the region today and remain over the area through the end of the work week.
1001 AM EDT Tue Oct 4 2016 Building high pressure will maintain dry and warm weather for much of the week. High pressure should maintain dry weather the rest of the day with temperatures several degrees above seasonal levels.

Looking ahead, a weak mid/upper level trough stretching from western Saskatchewan into central Montana this morning will push into western ND this afternoon/evening.
640 AM CDT Sun Mar 26 2017 Upper level trough moving into northern New Mexico will be the weather maker for the short term period. the warm front and associated surface moisture does not look to get into southwest MO until Sunday evening. Highs will range from around 60 in the Lake of the Ozarks region to near 70 in extreme southwest Missouri closer to the warm front.
1212 PM EDT Sun Mar 26 2017 High pressure will crest over the region on Today. Low pressure will approach from the west tonight into Monday. Temperatures this hour have climbed into the low to mid 20s north and into the lower 30s downeast. Clouds will continue to increase tonight as the high continues to move east and a warm from approaches from the west. Pcpn wl gradually wind down late Mon ngt but expect pcpn to continue acrs the far north in wrap-arnd cyclonic flow with upr-lvl trof lurking nr the region.
616 AM CDT Sun Mar 26 2017 Winds have turned light and stratus has slowly settled this morning in areas along and just west of the Buffalo Ridge. Conditions will slowly improve mid- morning, with fog hanging around the higher elevation areas through noon. This morning: A narrow corridor of light rain persists across parts of Southwest Minnesota, tied to vorticity axis on the northwestern quadrant of larger upper low centered over western Illinois. Elsewhere, stratus will remain, with visibilities dipping below one mile at times along the Buffalo Ridge into mid morning.
1022 AM EDT Sun Mar 26 2017 A front will remain stationary across the area through this evening before returning as a warm front late tonight and Monday.
Temps given this persistent southerly advection will stay at least 5- 7 degrees above normal for highs today and slightly warmer for Monday with many locations close to the 80 mark.
A weakening stacked low pressure system is centered in the vicinity of Quincy, IL and Burlington, IA early this morning. The mid/upper level portion of the system has a trough axis extending southeast to the Gulf of Mexico. As the trough moves northeast, it is interacting with a moist flow of air off the Gulf, resulting in a large area of showers.
633 AM CDT Sun Mar 26 2017 The low clouds mentioned earlier continue to lift slowly northward, and now encompass most of the area except the Devils Lake region into the northern Red River Valley.
935 AM EDT Sun Mar 26 2017 A weak U/L trough will push across the region today, with strong ridging surface and aloft developing in its wake tonight and Monday. The trough has weakened the mid level subsidence inversion and has slightly increased deep layer moisture with PCPW climbing to just over an inch on the TBW 12Z sounding.
A lull in the weather will continue for central and southern Nevada as weak ridging quickly moves across the state.
with weaker storms driven by low amplitude upper level troughs. A weak long wave ridge is now moving out to the east. An upper level trough is approaching the coast. Winds have been gusty over the ridges. The last of the short waves and the long wave trough will move through the area Monday. Showers will diminish in the wake of the trough. After that, there will be a longer break in the action as a long wave ridge moves toward the west coast.
Weak high pressure aloft will keep some scattered to broken mid level clouds over the mountains, while the plains remain mostly clear.
Upper low is working its way out of the region towards the Great Lakes, which will decrease precip chances as the day progresses.
A moist southerly lower level flow has returned bringing low stratus and patchy fog to our area in response to falling surface pressures across the Plains ahead of an upper level trough moving to the east over the Central/Southern Rockies. A strong cap may persist inhibiting convective development, however, solar heating and a left exit region of a compact upper level jet as the trough moves across the Plains could break it allowing for isolated storms that would rapidly become strong to severe late this afternoon into evening. The trough moves further to the east on Monday toward the Mississippi Valley causing a weak cold front to drift into the Hill Country and Central Texas by midday and stall across our area.
The area of low pressure will lift northeast into the Lake Michigan region and as it does, the areal extent of the drizzle and showers will diminish. Temperatures will have a difficult time making much progress while these low clouds persist though they should raise a bit this afternoon as the low continues to depart to the east. The next upper low system now over southeast Colorado will reach eastern Kansas tonight.
402 AM PDT Sun Mar 26 2017 Dry and a little warmer today under weak high pressure aloft. another low pressure system will move inland through California with cooling.
Max Temps will reach into the lower 80s inland while an Atlc Coast Sea Breeze will develop and push well inland and keep the Atlc Coast in the 70s for Max Temps.
714 AM EDT Sun Mar 26 2017 Aviation/Marine Rain will continue today and tonight as low pressure moves across Lower Michigan.
As the low-level inversion begins to lift and break, expect the ceilings to either scatter out, or else to lift to all MVFR between 14Z and 17Z, and then to VFR between 17Z and 22Z.
