A high pressure system over the region will result in above normal temperatures through Saturday.
850 AM MST FRI MAY 13 2016 Strong high pressure aloft will bring well above normal temperatures through Saturday.
Forecast appears on track with a cold front moving across Se Ga this afternoon and Ne Fl tonight. as a cold front approaches. Scattered to numerous storms will move east across the waters this afternoon and early evening in advance of a cold front.
Upper level ridge has the region under a dry southerly flow, warming temperatures near 15 degrees above normal. Ahead of cold frontal passage tomorrow, may see isolated showers over Harney County tonight. Warm and dry conditions are expected today as the upper level ridge amplifies over the area. The next upper level trough moves onshore early Saturday morning with the potential for showers developing mostly in the Oregon zones.
15z subjective surface analysis indicates high pressure centered just northeast of little rock. A new cold front will drop south into the state late in the period. this will be short lived as another cold front will drop south through the state late tonight into Sat morning. with another shot of cooler and drier air to the state.
and cooler air moves into the region for the weekend. with better chances coming for the latter portion of the weekend as the boundary returns north as a warm front.
An approaching cold front this evening will bring chances of thunderstorms to each taf site. Winds will shift around to the northeast behind this cold front at kcds early Saturday morning. This trough will be draped from southeastern New Mexico into the eastern Texas Panhandle by late this afternoon and also ahead of a strong front. This cold front will be the primary driver of convective development during the overnight hours.

1006 AM EDT FRI MAY 13 2016 Drier and cooler weather will advect into the region today, in the wake of a cold front. Another cold front will move through Saturday morning, bringing a chance of rain. An upper level low will settle into the Great Lakes this weekend, providing cooler temperatures and a lingering chance of a shower. digging h5 s/w will allow a sfc cold front to drop se thru iln/s fa early saturday. lows tonight continue close to normal, ranging from the mid 40s nw to the lower 50s se. Highs on sat will be about 15 degrees below normal, ranging from the lower 50s north to the upper 50s south. expect Clouds clouds to begin to break up allowing temps to drop to lows ranging from the upper 30s north to the lower 40s se.
1120 AM EDT FRI MAY 13 2016 A reinforcing cold front crosses Saturday morning.
956 AM EDT FRI MAY 13 2016 Water Vapor imagery showing longwave trough from the Great Lakes swinging into the Deep South pushing a weak surface front into the Northern Gulf Coast region this morning. Weak Western Atlantic high pressure extends back into the area while weak frontal boundary sags into the E Gulf today.
Temperatures this afternoon to climb into the low to mid 80s.
908 AM EDT FRI MAY 13 2016 A strong cold front will move across the forecast area tonight ushering in much below normal conditions. A punch of drier air has spread over the area behind the cold front with the last of the sprinkles ending in nw pa. On average most places should be partly sunny today but highs will be about 10 degrees cooler than yesterday. A weak upper trough pushing across lake erie could trigger an isolated shra in the snowbelt this afternoon. Models in good agreement dropping arctic cold front. At the upper levels deep upper trough digs over the NERN states. Temps will hover in the lower to mid 50s all day.
Offshore flow and a building upper level ridge of high pressure aloft will make for a dry and very warm day for most of the area today.
High pressure is sliding south across the Southern Plains early this morning, with rather cool and decidedly less humid conditions over the area. Slightly higher dewpoints will begin to advect in across Kansas and northern Missouri by afternoon, resulting in a ribbon of CAPE ahead of an approaching cold front. That front will then usher in a much cooler airmass for the overnight hours tonight, with lows likely falling into the 40s by Saturday morning.
207 AM EDT Fri Mar 17 2017 High pressure will slide off to the south of the region tonight. A complex frontal system will move through the region Friday night and Saturday, before high pressure returns for the end of the weekend.
Light and variable winds will occur across our area, and along with the mostly clear skies will result in ideal radiational cooling, allowing temperatures to continue to drop into the low-mid 30s inland.
The high level clouds over Utah now still on track to stream into Colorado this evening allowing for low temps tonight across northern UT and CO to moderate a few degrees as compared to last night. Temperatures on Friday will increase once again as a high pressure axis moves over the region again. The fortunate part with these high daytime temperatures is that at night the low temperatures are cooling enough to slow snowmelt into our streams and rivers. Southwest winds will increase on Saturday afternoon with the next longwave trough moving onshore the west coast.
522 AM CDT Fri Mar 17 2017 A cold front will move through the Panhandles this morning with winds shifting to the north and northeast 15 to 20 mph or 15 to 25 mph with higher gusts by late this morning.
638 AM EDT Fri Mar 17 2017 A ridge of high pressure will build into the region with clearing skies and cool temperatures expected today and tonight.
It should also be allowed to melt quickly, as the snow level recovers after the trough passes.
303 AM MDT Fri Mar 17 2017 Current observations across Wyoming and western Nebraska show a weak cold front located near Riverton in central Wyoming, stretching southeast past Laramie and along the Colorado/Wyoming/Nebraska border early this morning. Today will be slightly cooler into the afternoon, but temperatures will still be pleasant with relatively light winds. Pleasant warm weather is expected this weekend as temperatures rebound on Saturday as another ridge axis quickly moves eastward and amplifies across the central Rockies. Afternoon temperatures in the 70's to low 80's are expected across the high plains with slightly lower readings in the upper 60's west of I-25 including Rawlins and Laramie.
353 AM CDT Fri Mar 17 2017 (Today and Tonight) Look for dry conditions and warmer than normal temperatures for the next 24 hours.
A cold front move into HOB/MAF/INK late in the forecast period.
Latest WPC Surface analysis shows the high pressure resting comfortably over northern Florida with the center over the panhandle. with the addition of Florida mainland heating the high pressure system will fracture this weekend between the northern Gulf of Mexico out to the mid-Atlantic.
1129 PM MDT Thu Mar 16 2017 Winds are on the steady decrease this evening across the forecast area, enough so to allow the High Wind Warning and Red Flag Warning to expire on time. A cold fropa tonight will yield cooler temperatures for Fri with no high impact weather expected.
Generally dry weather can be expected across the region today as upper ridging builds over the Northern Rockies. Dry weather will continue into Saturday as upper ridging remains over the region and heights build aloft. Lee troughing over the area will support downslope winds, strongest across the western foothill locations. High temperatures in the 50s can be expected for most of the lower elevations today with temperatures warming into the 70s for most locations on Saturday.
634 AM EDT Fri Mar 17 2017 Today will be quiet as high pressure briefly builds into the area. High pressure builds in today cutting off the NW flow and bringing mainly clear skies. Fresh and deep snow cover will keep temps down a bit below what you would normally see given the time of year and ridge. this will delay the onset of the precipitation from the approaching warm front until very late at night. To begin the period Saturday evening, a closed 500 mb low will be located over PA with a developing low pressure system at the surface over the western Atlantic and an inverted trough hanging back into PA.
342 AM CDT Fri Mar 17 2017 Cold front at 08z was moving into the Red River valley. Signifcant warming occurs at 925-850 mb layer Saturday night with 850 mb thermal ridge peaking 12z Sun with +10 to +16C 850 mb temps at that time.
After another cold start this morning, temperatures will warm into the upper 60s to low 70s across the interior, and the low to mid 60s near the coast due to a light onshore flow. Low level moisture will slowly rebound due to the light onshore flow, and temperatures tonight will be warmer in the 40s, and near 50 along the coast.
1238 AM CDT Fri Mar 17 2017 A cold front will push south tonight, however this front will be Pacific in nature, and hence downslope momentum will be fairly substantial behind it. Temperatures should top out from the upper 60s to lower 70s, which is the higher end of most guidance, and justified given our very dry conditions.
333 AM EDT Fri Mar 17 2017 A ridge of high pressure will build into the region with clearing skies and cool temperatures expected today and tonight.
126 AM EDT Fri Mar 17 2017 Dry weather is expected tonight under high pressure. Precipitation chances return Friday and Saturday with approaching low pressure. Crossing low pressure across the Great Lakes will subdue the brief benign weather by Friday late morning. Some freezing rain can be mixed in the coldest regions - the valleys within the ridges and across the northern zones where ground temperatures may take longer to warm above freezing. An upper low is progged to cross the lower Great Lakes and Upper Ohio Valley region Saturday, reaching the Mid Atlantic coast Sun.
356 AM CDT Fri Mar 17 2017 The latest sfc analysis was indicating a wave acrs southwestern IA, with associated warm front extending southeastward along and just south of the DVN CWA into southern IL. Passing sfc trof and wave will veer the llvl winds to the west and increase them to 10-20+ MPH with higher gusts during the same time frame, but some lag in cool advection by this flow until late in the day.
410 AM EDT Fri Mar 17 2017 Cool high pressure over the area this morning will move off the southeast coast this afternoon. A cold front will bring a chance of brief showers Saturday.
1119 PM MDT Thu Mar 16 2017 20z surface analysis had low near KICR with trough into central WY and cold front into southwest SD into northeast WY. Friday, much cooler day expected. Upper ridge will build over the Rockies and head toward the CWA Friday night. Strong upper and thermal ridge expected Saturday with highs 15-30F above normal in the southwest and 5-15F above normal in the northeast given downslope flow and deeply mixed boundary layer.
Look for a pattern change this weekend as the next system moves in from the Pacific with cooler weather, clouds, and light rain showers.
An area of low pressure will move through southern Manitoba tonight, reaching northwest Ontario on Friday. Meanwhile, an upper level trof will close off into an upper low by Friday afternoon. As temps cool this evening, the rain will mix with snow, or just turn into freezing rain, then become all snow later this evening and overnight. Freezing rain is still possible for a time overnight as there will be just enough warm air just above the surface to melt the snow as it falls and turn it to freezing rain. A light glaze of ice is anticipated where freezing rain occurs. Confidence is low in the freezing rain and the amount of ice it may produce. An upper level ridge builds into the forecast this weekend with partly to mostly sunny skies along with above normal temps.
338 AM CDT Fri Mar 17 2017 Low level moisture continues to stream north into the Ozarks this morning as low pressure develops across southwestern Kansas. We suspect that the low levels will moisten over a deep enough layer to produce areas of drizzle from the predawn hours into this morning. A cold front will then move southeast into the Ozarks this afternoon likely reaching the I-44 corridor around 21 UTC. High temperatures today will actually be warmest behind that cold front across extreme southeastern Kansas and west-central Missouri due to clearing skies and cold air advection lagging. Highs should make the lower 70s over this area. In contrast, areas of south-central Missouri should only warm into the lower 60s due to persistent cloud cover. Large scale upper level ridging will then build over the area this weekend.
With temperatures hovering around freezing in Rolette County, we made a few calls and it sounds like there are now a few slick spots on area roads, especially towards the Turtle Mountains. This could lead to winds as high as 35 mph briefly before the pressure gradient relaxes as high pressure moves in. An upper level ridge quickly builds back into the Dakotas Saturday with strong warming over the west. There should be a large temperature difference across our area, with highs reaching into the 60s in far southwestern ND while the Turtle Mountains remains in the lower 30s.
341 AM EDT Fri Mar 17 2017 Cold high pressure will prevail through today.
637 AM EDT Fri Mar 17 2017 An approaching cold front will bring a mix of snow, sleet, and freezing rain across our area early today. However, temperatures should rise above freezing by late morning, diminishing any travel hazards by noon.
127 AM EDT Fri Mar 17 2017 Canadian high pressure over the area tonight providing another very cold night with a hard freeze expected. It will be warmer Friday due to a developing southerly flow as the high moves into the Atlantic. A cold front will bring a chance of brief showers Saturday.
315 AM CDT Fri Mar 17 2017 08z/3am surface analysis shows 1009mb low over western Iowa with warm front extending southeastward into central Illinois. Have therefore carried likely PoPs during the morning hours, with the higher PoPs quickly shifting into the far east and southeast by early afternoon as a cold front pushes into the area. Once the front passes, a cooler/drier airmass will arrive tonight with lows dropping into the lower to middle 30s. High pressure will provide quiet weather across central Illinois this weekend.
Although temperatures will rise close to and above normal for the first part of this weekend, the weak cold air advection behind the cold front will moderate temperatures on Saturday.
348 AM CDT Fri Mar 17 2017 The surface map this morning features an area of low pressure over southern Manitoba with a cold front crossing the CWA. Winds will shift to the west, then northwest behind the passage of this cold front. A secondary cold front in NW ND will slide across the CWA by the mid morning hours with gusty winds and cloudy skies expected. The WAA, along with upper level ridging will spread across the eastern Dakotas Saturday night with lows only falling into the 30s.
Passage of the surface front and mid/upper trough axis occurs Saturday morning, and rapid drying/clearing should follow.
321 AM EDT Fri Mar 17 2017 Today will be quiet as high pressure briefly builds into the area. High pressure builds in today cutting off the NW flow and bringing mainly clear skies. Fresh and deep snow cover will keep temps down a bit below what you would normally see given the time of year and ridge. this will delay the onset of the precipitation from the approaching warm front until very late at night. To begin the period Saturday evening, a closed 500 mb low will be located over PA with a developing low pressure system at the surface over the western Atlantic and an inverted trough hanging back into PA.
252 AM PDT Fri Mar 17 2017 High pressure ridge will start breaking down as a cold front moves into Central California Saturday afternoon and evening with light showers across Yosemite.
310 AM EDT Fri Mar 17 2017 A ridge of high pressure will build into the region with clearing skies and cool temperatures expected today and tonight.
115 AM EDT Fri Mar 17 2017 An approaching cold front is expected to cause a mix of snow, sleet, and freezing rain across our area late tonight and Friday morning with just some light rain or drizzle in the afternoon as temperatures rise above freezing.
Showers and a few thunderstorms will affect the forecast areas late Friday afternoon and during the evening hours, as weak instability develops ahead of a cold front, that will approach from the north.
413 AM MDT Fri Mar 17 2017 A flat ridge will be over the area today as a weak disturbance moves over northern CO and southern WY. The upper level ridge will rebuild over the area tonight. Highs today across the southeast plains will be around 10 degrees cooler than yesterday, in the wake of a front. Look for highs in the upper 60s to lower 70s across the plains, and in the 60s in the high valley locations.
354 AM EDT Fri Mar 17 2017 High pressure will build in from the west today providing dry but cool weather. High pressure will slide off shore Saturday as low pressure develops south of New England.
With the center of the high near the area, winds will likely go calm tonight under mostly clear skies. The official forecast went close to the cooler MOS guidance given the expected radiational cooling conditions. Another upper level low will traverse the Great Lakes region Saturday, with the associated trailing cold front moving through the region during the daytime.
306 AM CDT Fri Mar 17 2017 A cold front is moving though our area this morning. Models and MOS are in reasonable agreement clustered around the lower 70s for most of the area, possible only as warm as the upper 60s around Hays and Wakeeney.
High pressure is beginning to build into the western US this morning, which will quickly transition into a moist southwesterly flow over north central Idaho and western Montana during the day so cloud cover will increase and lower by this afternoon.
Models have an upper ridge with weak zonal flow aloft over the CWA Saturday and Saturday night.
415 AM EDT Fri Mar 17 2017 An approaching cold front will bring a mix of snow, sleet, and freezing rain across our area early today. However, temperatures should rise above freezing by late morning, diminishing any travel hazards by noon.
219 PM CDT THU JUN 23 2016 209 PM CDT Surface plots indicate convergent winds along an inverted trough extending from Winnebago and Ogle Counties SE toward Kankakee. Trough feature will wash out this evening, leaving a humid airmass in place with surface to H85 RH values 85 to 95 percent. H85 temps rise into the middle teens which should correspond to max temps in the mid 80s, except cooler near the lake.
Low level moisture continues to advect northward into the forecast area underneath the upper level ridge in place this afternoon, yielding muggy conditions and an increase in scattered fair weather cumulus across the region. A few shallow showers were able to develop a few hours ago, generally in areas confined to the coast in our far southwestern and southeastern Florida counties where dewpoints have managed to remain in the lower 70s so far this afternoon. Cloud cover is expected to dissipate with the loss of daytime heating this evening, with temperatures falling into the lower 70s inland and mid 70s near the coast.
Otherwise, still expecting a pleasant weather day with high pressure in control. Current large scale pattern shows deep cut off low just off the Pacific Northwest coast, slowly progressing eastward, with an upper level ridge centered over the Northern Plains. The deep upper level low reaches western Montana by 00z Sat with southwest flow aloft over our region while low level southerly flow continues advecting moisture northward.
Building high pressure will lead to an inland warming trend Friday and through the weekend. Despite mostly sunny conditions this afternoon, temperatures will likely be the coolest of the week due to increased onshore flow and slightly cooler temperatures aloft. Overall, afternoon temperatures will be near seasonal averages today with low/mid 70s coast, 70s inland near the bays and into the low/mid 80s inland. SFO Bridge Approach.
a cold front will be dropping south across portions of MO. Today through Friday night Upper ridge remains in place but has been been flattened out by a short wave trough thats moving through the Ohio valley. This trough is producing widespread severe weather in the Ohio Valley as it merges with a larger trough off the eastern seaboard. As Ohio Valley system moves into the eastern United States, it will drag a cold front towards the region from the north.
(Issued 1042 AM CDT THU JUN 23 2016) Warm start to this morning as temps were mainly in the lower 70s. That trend continues with current obs across the TN Valley ranging from the lower 80s under some cloud cover in NE AL to the upper 80s in NW AL. High pressure remains anchored across the region along with mid and upper-level dry air as seen on WV satellite. High temps today will be in the low-mid 90s. Southwesterly winds will become more westerly and gusty after 24/16Z at both TAF sites on Friday as a cold front stalls over northern Alabama.
246 PM EDT THU JUN 23 2016 A cold front sinking southward and into Virginia today and North Carolina Friday will move into the forecast area Friday night. Freezing level and WBZ heights will be 15 kft and 13 kft respectively and with hot temperatures hail threat will be lowered.
Despite this low value, enough low level moisture was in place over the Gulf waters and that was leading to some isolated showers. a weak cyclonic circulation/inverted trough was moving westward over the east coast of Mexico from the western Gulf. As the inverted trough moves inland, subsidence over deep south Texas was decreasing while lift/moisture was slowly increasing.
315 PM EDT THU JUN 23 2016 No real sensible weather concerns tonight as an expansive high pressure area over the Northern Plains continues to build toward the Western Lakes.
Short wave trough and attendant cool temperatures aloft will aid in the development of widely scattered showers across central and northern zones late this morning and this afternoon. Otherwise, Partly to mostly sunny skies are expected along with warmer temperatures than yesterday.
1244 PM CDT THU JUN 23 2016 An upper level ridge that extends from New Mexico across Texas into northern Florida will continue to be the main weather feature across the region through Friday.
No convection on the scope thanks to the ridge aloft and a strong cap between h85 and h7. The ridge will remain in control over the area with low level temps continue to rise a degree or two.
Heat Advisory for Northwestern Middle Tennessee this afternoon Dew points will be running a tad higher than previously forecast over northern parts of Middle Tennessee, as moisture pooling takes place ahead of cold front dropping southward across the Ohio River Valley. A cold front will drop southward into southern Kentucky this evening and produce the the likelihood for isolated to scattered thunderstorms, especially over northern parts of the Mid-State.
700 PM EDT THU JUN 23 2016 No real sensible weather concerns tonight as an expansive high pressure area over the Northern Plains continues to build toward the Western Lakes.
304 PM CDT THU JUN 23 2016 Weak high pressure across the region has brought a stellar day to the area, with temps in the 70s and lower 80s, and comfortable humidity.
MUCH COOLER FRIDAY. RETURN TO WARMER CONDITIONS STARTING THIS WEEKEND. In general, snow amounts should be on the light side, except several inches possible in the higher terrain of Glacier National Park. Breezy conditions should also be common in the valleys with significantly stronger winds over the higher terrain.
