403 AM CST Fri Nov 11 2016 Today through tonight, High pressure with mostly clear skies have allowed temperatures to fall into the mid/upper 30s over much of North Central and Northeast MS overnight, and this has resulted in the threat for patchy frost in the Golden Triangle region. Dry northwest flow aloft will send another cold front toward the forecast area later today into tonight. This rain-free front will push through the ArkLaMiss region overnight and bring a reinforcing push of drier and cooler air.
621 AM EST Fri Nov 11 2016 A cold front will cross the region this morning, bringing colder air and gusty winds this afternoon into Saturday. Low Pressure may bring unsettled conditions midweek. Showers are entering the north as a cold front crosses the region. High pressure moves in overnight.
Otherwise, made minor adjustments to temperatures and dew points based on observations with temperatures expected to rise into the low to mid 70s under partly to mostly cloudy skies. /ISSUED 408 AM CST Fri Nov 11 2016/ Surface analysis this morning has weak high pressure over much of Texas. Water vapor imagery shows closed upper low over the S Rockies with SW flow aloft over much of the Texas Gulf coast. Lift from an embedded short wave trough has allowed for a few showers to develop from College Station to Bay City. An amplified upper level pattern should continue as the upper low over the S Rockies shears out over Texas as another trough axis shears out over the Mid-South.
925 AM EST Fri Nov 11 2016 A cold front will cross the region this morning, bringing colder air and gusty winds this afternoon into Saturday. Low Pressure may bring unsettled conditions midweek. Cold front is moving toward the coast now, with winds right behind the front gusting to around 30KT (35 MPH). Showers are entering the north as a cold front crosses the region. High pressure moves in overnight.
152 PM EDT Mon Oct 31 2016 A front that slipped south of the area last night, will return as a warm front tonight.
That flow will be enhanced a little with pm gusts as the gradient tightens some with a passing Great lakes wave to the north/west atop of the strong upper ridge.
Zonal flow across the area this tonight and Tuesday transitioning to ridging by Tuesday. Cooler day on Tuesday with downslope gradients still in place but less mixing will keep temperatures below 60 degrees. Mountains will see mountain shower activity especially during the afternoon as the flow turns a bit more cyclonic ahead of a ridge beginning to build into the Pacific Northwest.
Normal high temperatures for this time of year are usually in the lower 60s, and tomorrows high temperatures will range from the mid to upper 70s.
254 PM CDT Mon Oct 31 2016 Early-afternoon water vapor imagery and 12z upper-air analysis revealed the presence of a west-southwest mid-level flow regime stretching from a vigorous trough just off the Oregon and California coasts into the northern and central Plains. In the low levels, a surface cyclone attendant to this mid-level disturbance was analyzed over central North Dakota as of 18z with a trailing cold front (presently masked by downslope warming) extending south into central Nebraska.
A low pressure system moving across the area will keep temperatures down a bit while also producing some clouds along with a slight chance of showers in Lincoln County Tuesday.
SHORT TERM (Today through Tuesday): Isolated showers continue to remain offshore this afternoon as weak subsidence and midlevel dry air associated with the ridge aloft continue to stifle shower development despite the presence of a weak inverted trough over the Lower Rio Grande Valley. This will combine with additional forcing from the weak upper-level disturbance that will rotate around the ridge over the Gulf to cause isolated to scattered showers and thunderstorms late tomorrow morning and afternoon across the eastern half of the region. Highs tomorrow will be similar to today's remaining in the 80s aside from a few spots in the lower 90s along the Rio Grande.
/This evening through Tuesday/ Weak cold front aloft to continue to drop through the CWA tonight as the area of low pressure situated across SE SD continues to lift ENE into SRN Ontario. Even though cooler air pushing into the CWA than in previous nights, remaining cloud cover should help keep lows from dropping off too much. /Tuesday night through Monday/ Frontal boundary that moved through overnight will then begin to lift back northward Tuesday as a warm front becoming situated across the southern third of Iowa toward Tuesday night.
126 PM EDT Mon Oct 31 2016 High pressure across the western Great Lakes will shift east tonight and be overhead for Monday.
358 PM EDT Mon Oct 31 2016 WSW flow aloft and 996mb low pressure over the Dakotas is resulting in broad strong warm air advection from the northern plains to the Upper Great Lakes. Strong low pressure moving from the northern Plains to north of Lake Superior tonight will result in gales to 40 knots over the east half of Lake Superior tonight. Once the low moves northeast of Lk Superior, west gales to 35 kts are expected Tue over Lake Superior, especially for the west half.
605 PM EDT Mon Oct 31 2016 High pressure centered over the eastern Great Lakes will shift to the east coast overnight. A warm front will lift north across the region on Tuesday.
1150 AM MDT Mon Oct 31 2016 A cold front will move through NE UT and NW CO this morning and early afternoon. As this front moved into the KSLC area precipitation increased and cloud tops have grown cooler. The front eventually washes out this evening, then another progressive trough and cold front approach NE UT Tue afternoon.
High pressure aloft will settle over the Great Basin midweek.
Models show the core of this 95-105kt jet sagging southward overnight as the deepening longwave trough over Nevada slowly migrates eastward towards the region. Past few hours high country wind speeds have weaken while winds on the plains notably in the higher areas along the northern border and along the Palmer Divide have picked up in speed with gusts in the 20-30 mph range in these higher areas. Strong flow aloft will still be over Colorado but through the day winds aloft will become more swly as the deepening upper level trough over the Great Basin moves closer. and in its wake cooler and slightly more humid air. Do not see as much cooling in the high country.
So far, the highest gust I've seen this morning has been at La Veta Pass where a gust to 61 mph was reported at 2:35 am. Sensors around the Junkins Fire indicate peak gusts of generally 30-40 mph so far, with 45 mph being the highest gust I've seen, occurring at a sensor well south of the fire at 2:56 am.
Later in the week, a low pressure system will pull moisture across Arizona producing a chance of showers and thunderstorms.
Later tonight low level moisture increases as a surface and upper trough approach.
323 PM EDT Mon Oct 31 2016 High pressure will build across the region through tonight.
Deep southwesterly flow over the region with abnormally high geopotential heights aloft will result in another day with high temperatures near 15 degrees warmer than normal.
A weak cold front is sliding south across Kentucky at this hour, with just enough post-frontal moisture to continue mention of a pockets of drizzle or sprinkles. South winds stay up a bit overnight, which should yield mild lows in the low 60s in most spots. Upper ridge centered over the Gulf Coast will strengthen over our region by Tuesday. Good mixing up around the 850 mb level will help translate 13-14 C 850 temps to the low and mid 80s at the surface.
Reinforcing ridge of high pressure building back in north of the area will gradually increase low level E/NE winds across central Florida. Expect a little more cloud cover tomorrow, but still partly sunny with highs still reaching the low to mid 80s. Mid-level anticyclone retrogrades into the gulf mid week. High Temps remaining above normal in the low to mid 80s with mild low temps in the mid 60s, except lower 70s immediate coast. Great Lakes trough digs well south into FL by late Fri and shifts east of the state Sat, possibly briefly cutting off.
306 PM CDT Mon Oct 31 2016 MSAS sfc pressure analysis had a low pressure trough in the Plains with the low itself centered in eastern North Dakota. The eastern periphery of the low stratus have actually been slowly eroding westward through the day. Also, analyzing forecast 925-850mb RH fields and moisture flux convergence, there will likely be an increase in low-level clouds through the afternoon into the evening along a developing warm front. For these reasons, nudged highs down toward CONSALL values, slightly cooler than SuperBlend.
228 PM EDT Mon Oct 31 2016 Very mild air will overspread tonight into Tuesday as a warm front lifts through.
With good mixing and subsidence behind the trough axis, winds have increased over the past few hours, mainly for areas along and east of the Laramie Range. An upper trough will amplify into northern Utah by Tuesday.
248 PM EDT Mon Oct 31 2016 A front that slipped south of the area last night, returns as a warm front tonight.
Deeper moisture pool continues to advect north through the Coastal Bend and Victoria Crossroads, east of the upper level low centered across the Rio Grande Plains. The upper level low will shift north into the Hill Country by Tuesday morning and them open and shear northeast Tuesday afternoon.
Snow amounts will vary between 2-4 inches around 6000 ft up to 8 inches over the highest peaks of the Sierra. Upper ridging then builds over NorCal providing drier weather with minor warming through the mid-week period.
*** The stacked low pressure system responsible for this Halloween rain and wind is slow to get out of eastern Montana, but the main impacts are beginning to wane this afternoon.
229 PM MDT Mon Oct 31 2016 Broad weak amplitude upper trough extends across the Pac NW into the northern Plains. Will also downgrade the High Wind Warning for Butte and Perkins counties to an advisory based on latest obs. Upper trough axis will move into the Great Basin region Tuesday with southwest flow across the region. Mean eastern Pacific trough will support a mean ridge over the western-to-central CONUS through the entire week.
Surface pressure falls across the plains will shift east today and force the ridge of high pressure out of the region. This displacement plus a strong southwesterly low-level jet should force a warm front northward through the CWA.
It is partly to mostly cloudy along the island chain with temperatures in the lower 80s. As mid to upper ridging reaches eastward through the eastern Gulf of Mexico and across the state, in conjunction with drier air pushing in aloft, the probability of measurable rain diminishes overnight and into early Tuesday. The dry forecast will extend through the middle of the week thanks to the localized ridging.
Southerly surface flow will persist through Tuesday as flow aloft becomes southwesterly with the eastward propagating upper-ridge. The boundary will stall as a large upper ridge builds over the southeastern CONUS. A steady supply of Gulf moisture will enter the local area along the western periphery of the ridge, which will set the stage for the next chance of mentionable widespread precipitation beginning Tuesday night.
Much cooler, more seasonable autumn air mass expected starting Tuesday and continuing through the remainder of the week.
353 PM CDT Mon Oct 31 2016 The upper ridging that has dominated our weather for several days is beginning to shift east. The arrival of 60F+ dew points will coincide with the onset of the low ceilings.
A cold front will slid southeast into the area this evening, effectively making trick-or-treating very comfortable as wind speeds drop near the front and temperatures remain warm. The tricky part come later as cooler air works in, but still remains light. A cold front will approach from the northwest and eventually cause wind to decrease and perhaps become variable for several hours as the front moves rather slowly.
134 PM EDT Mon Oct 31 2016 High pressure over the Great Lakes will advance down the east slopes of the Appalachians today and tonight behind a cold front.
Medium Pronounced WAA regime will continue into tonight with thermal ridge axis becoming established ahead of approaching frontal boundary.
Ridge building over the region bringing much drier air into the area will limit the potential for rain tonight into Tuesday.
155 PM EDT Mon Oct 31 2016 High pressure centered over the Great Lakes early this morning will build to the east and it should influence our weather through Tuesday.
South winds turning to the west/northwest following the cold front will remain breezy through the evening but should gradually diminish towards morning. Main highlight will be above normal temperatures with highs in the 50s and 60s with lows above freezing. High confidence with building upper ridge into the weekend. although considering the strength of the upper ridge it may take a few days longer for the pattern to evolve than what models are suggesting. Low pressure near the central ND/SD border as of 18z will move northeast throughout the period resulting in south/southeast winds this afternoon switching around to the west/northwest this evening and overnight.
Large scale high pressure ridging on top of the southeast CONUS with dry air and subsidence overhead and no precipitation to speak of.
343 PM EDT Mon Oct 31 2016 High pressure will travel east of the Great Lakes region tonight allowing a warm front to push northeast into the area.
301 PM CDT Mon Oct 31 2016 At h5 trough along the Pacific northwest coast with stronger wave moving through the Dakotas as seen in IR. There is a strong Hudson Bay low with a trough into the northeast CONUS. At the surface 994mb low near Fargo with a cold front through central Nebraska. The lower elevations in the Platte River valley will fall to near freezing. Cooler air over western Nebraska on Tuesday with passage of cold front yesterday. Temperatures on the order of 10f to 15f degrees cooler.
256 PM CDT Mon Oct 31 2016 Under sunny skies temps have warmed into the low to mid 80s this aftn.
258 PM EDT Mon Oct 31 2016 Warm air advection ongoing ahead of low pressure in the plains is leading to developing light showers/sprinkles over northern MN and into western WI. Upper air pattern consists of a 500 mb ridge across the central U. with troughs in New England and another on the west coast. Strong low pressure moving from the northern Plains to north of Lake Superior tonight will result in gales to 40 knots over the east half of Lake Superior this afternoon into tonight. Once the low moves east of Lk Superior, west gales gusts to 35 kts are expected Tue over much of Lake Superior.
These showers were associated with a weak cold front moving towards the region. Min temps tonight will be much cooler that todays earlier min temps, with lows in the 40s most of the plains and 20s and 30s mtns. It will be cooler with much less wind over the region. Temps will cool into the lower 60s across the lower parts of El Paso county to low 70s across the southeast plains. Skies will be mainly clear across the lower elevations but a few showers cant be ruled out across the NW slopes of the central mtn region.
From the start of the extended, in the upper levels, a low closes off over the southwestern states while a ridge dominates the High Plains region into the weekend. High temperatures will reach the lower 70s and maintain during this time.
319 PM MDT Mon Oct 31 2016 The cold front which has produced gusty winds at many areas throughout the day will continue to dissolve over western Colorado. A second trough reaches eastern Utah on Tuesday and keeps a cooler airmass overhead the region. This trough will bring a few isolated showers to the higher terrain on Tuesday, but will not produce any major impacts to the region. This trough will split into a northern half and southern half over the next few days with its axis sitting over the UT/CO border.
However, ridging develops over the Plains late in the week after a longwave trough moves from the Northern Plains and Canadian Prairies into the Great Lakes region.
307 PM EDT Mon Oct 31 2016 High pressure centered over the eastern Great Lakes will shift to the east coast overnight. A warm front will lift north across the region on Tuesday.
317 PM EDT Mon Oct 31 2016 High pressure will continue to build over the region through the rest of today.
145 PM CDT Mon Oct 31 2016 Winds are shifting to the west and northwest behind the low pressure trough this afternoon. Cooler, but still unseasonably warm weather, is expected behind the low.
Upper heights will rise on Tuesday as upper low off CA coast moves onshore and digs across the Great Basin. Temps at 850mb rise as thermal ridge edges eastward.
249 PM CDT Mon Oct 31 2016 Warm front has moved through the area as the temperatures and dew points have taken a jump. I have shaded toward the warm side due to the southerly wind staying up overnight and some cirrus flying over the ridge.
Still on track for some of our max temp records to be threatened today as we climb into the upper 80s and even into the lower 90s.
333 PM EDT Mon Oct 31 2016 High pressure over the northeast will keep dry conditions in central New York and northeast Pennsylvania through Tuesday night.
246 PM EDT Mon Oct 31 2016 A diffuse cold front over the northern Midlands will dissipate.
Also, an upper level high pressure ridge will remain parked over the Gulf of Mexico, keeping our area with above normal temperatures for Tuesday. 21 (Tuesday night through next Monday) By Tuesday night, a potent upper level trough will be digging southeastward into the souther AZ/northern Mexico area.
318 PM CDT Mon Oct 31 2016 Upper level ridging to remain anchored across the eastern U.

LOW PRESSURE WILL CONTINUE TO DEVELOP OVERNIGHT ACROSS KANSAS PROVIDING THE PRESSURE GRADIENT TO KEEP WINDS UP.
149 PM PDT Mon Oct 31 2016 A low pressure system is expected to bring a slight chance of showers, primarily from Merced County to Yosemite.
320 PM EDT Mon Oct 31 2016 High pressure building eastward across the North Country this afternoon and tonight will eventually scour out low clouds currently over the area for a mostly clear and cool night.
355 PM EDT Mon Oct 31 2016 High pressure over the northeast will keep dry conditions in central New York and northeast Pennsylvania through Tuesday night.
Remnant upper low seen on w/v imagery over s Tx will get absorbed in the sw flow aloft and move across cntl/ne Tx on Tue.
This precipitation is caused by a low pressure area centered along the nd/mn border late this afternoon. The low will move northeast into southern Canada by early Tuesday morning. High pressure will build into the forecast area Tuesday morning causing breaks in the clouds from south to north during the day.
Areas of fog were impacting much of the Ozarks this morning as high pressure slides east of the area and southerly winds return low level moisture to the area. This will also bring a return of temperatures in the lower 80s this afternoon.
Behind the clouds, cold front will follow suit with winds becoming northwest overnight.
321 PM EDT Mon Oct 31 2016 Temperatures in the lower 50s this afternoon across southeast Michigan, falling into the upper 40s post sunset, as mainly just some high clouds linger this evening, before low clouds reform overnight. Narrowing 850-700 mb theta-e ridge/moisture plume will be streaking northeast over Tri-Cities and Saginaw Bay region overnight, with PW values over 1. 25 inches, and low pop seems warranted with the convergence provided by the low level jet. At the very least, low level convergence with the front should support low clouds, which should temper the warm up during the day, but still sneaking into the lower 70s, especially toward Ohio border where 80 degrees is still not out of the question with with more sunshine.
It's not ghouls or goblins to blame for the heat, but the ongoing drought and the ridge of high pressure that has been so prevalent over the region these last few weeks and months. Tomorrow will be similarly warm as the ridge remains overhead.
155 PM EDT Mon Oct 31 2016 High pressure will continue to build over the region through the rest of today.
530 PM EDT Mon Oct 31 2016 High pressure will continue to build over the region through the rest of today.
648 PM EDT Mon Oct 31 2016 High pressure will build across the region through tonight.
Dew points continue to surge ahead of a warm front lifting up from the south, with mid 50s over the CWA and lower 60s just south of St. The cold front that is currently over the eastern Dakotas into northeast Colorado will make some headway on Tuesday, but will still be to our northwest by late Tuesday afternoon. 850 mb temperatures should surge to around 15C by afternoon, as a tongue of warmer air is transported northeast out of the southern Plains. A strengthening warm frontal circulation extending from eastern Kansas to N Illinois Tuesday night will start the development of rain showers and a few thunderstorms north of Peoria.
The upper wave continues east this evening which will force a cold front into southwest Kansas tonight with the front becoming stationary from northeast into south central Kansas late tonight through Tuesday. Cooler air spreading over the area behind the front will keep temperatures in the 70s over much of the area on Tuesday. Closer to the front over south central Kansas, highs will likely be a little warmer, in the lower 80s. Another upper level short wave trough moves into the western states on Tuesday.
521 PM EDT Mon Oct 31 2016 A diffuse cold front over the northern Midlands will dissipate.
An upper level trough continues to move southeastward through the Mid-Atlantic region, with an intensifying upper level jet streak to its south over the southeastern CONUS. Lows tonight will range from the low-mid 50s across SE Alabama and SW Georgia to lower 60s across much of northern Florida.
The well advertised cold front is continuing to make its way SW to the local area. Lows will still fall into the lower 50s overnight. Mostly cloudy skies in the morning should give way to mostly sunny skies in the afternoon, as high pressure to our west builds eastward. A somewhat tightening pressure gradient as the ridge builds in should produce winds in the 5-15 mph range, with some higher gusts, especially in the higher terrain. Minimum relative humidity values should be reduced into the low/mid 30s percent range in some spots Wed afternoon.
Dry and Cool weather is expected for Indiana the next few days as High Pressure from Canada settles across the central plains and the Ohio Valley.
High pressure at the surface was building over the region, and will make for a fabulous day across the Ozarks. This same high pressure system will facilitate the first widespread frost of the cold season across southern Missouri and far southeast Kansas. Conditions will be very ideal for maximum radiational cooling, leading to temperatures falling into the low to mid 30s. Meanwhile, a mean upper ridge will persist across the nation's midsection, keeping skies mostly clear and winds out of the south.
227 AM CST Wed Nov 9 2016 High pressure will settle into the Mid-South today.
As high pressure shifts south and east. Have a strong elevation shadow in the low temperature grid, with the warmest temperatures along the Buffalo Ridge.
230 AM CST Wed Nov 9 2016 High pressure was located across the region this morning with clear skies and light winds producing a wide spread in temperatures prior to sunrise.
