1255 PM EST Mon Nov 7 2016 A building ridge of high pressure over the eastern continental United States will bring seasonally warm and dry conditions to the North Country through Tuesday, with abundant sunshine expected.
However, a trailing mid-level trough is expected to remain just east and south of the CWFA. A cold front has slowly moved south across the area today with low clouds hanging around especially in the northeast. Around midnight, a secondary push of cooler and drier air will dive into the region with breezy northerlies persisting much of the day on Tuesday. High pressure then builds in during the late afternoon yielding diminishing wind speeds.
158 PM PST Mon Nov 7 2016 High pressure will prevail for most of the upcoming week with dry conditions, light winds and above average daytime temperatures. Few changes to the going forecast were made with high pressure to remain over the intermountain west. With this pattern for the next 3 days, expect the mid slopes and ridges to remain quite mild overnight.
The strong/expansive high pressure ridge covering the eastern CONUS will gradually weaken and settle south across the SE CONUS late tonight into Tuesday. The mid level ridge over Florida will slowly flatten as short wave trough dives SE out of Canada into the Ohio Valley. Tonight's mins will remain several degrees warmer along the coast (U60s-around 70F) compared to inland.
225 PM EST Mon Nov 7 2016 A building ridge of high pressure over the eastern continental United States will bring seasonally warm and dry conditions to the North Country through Tuesday, with abundant sunshine expected.
337 PM EST Mon Nov 7 2016 High pressure brings a stretch of dry weather through Tuesday.
Ground moisture and generally light winds will be favorable for fog formation but atmospheric lifting from the larger scale trough could hinder development.
1139 AM CST Mon Nov 7 2016 A band of light rain is pushing into the CWA early this Monday morning, ahead of an elongated trough moving across the Central Plains. This trough and a series of embedded vort maxes will slowly move east through the area today and tonight. Temperatures will be a few degrees cooler today given cloud cover and precipitation influences, though readings will still be close to average.
High pressure will bring dry and warm weather over the next several days. High pressure over the forecast area will continue to build over the next few days. Maxes will remain in excess of 10F above seasonal normals, but the strengthening ridge will also allow for the strengthening of valley inversions, resulting in increasing urban haze through the end of the work week.
Upper-level trough that has brought showers to the region today will remain north and west of the region through Tuesday night providing periods of showers with possibly isolated thunderstorms.
927 AM MST Mon Nov 7 2016 Dry conditions with well above normal temperatures can be expected today and tuesday as strong high pressure builds over the desert southwest.
1144 AM CST Mon Nov 7 2016 Main concerns for the next couple days: rain chances tonight, mild temps becoming cooler for Tue. as latest 08z surface analysis indicates ridge of high pressure over the Ohio River Valley. Cooler air advects into the forecast area behind surface front Tuesday with 925mb temperatures falling into the plus 1 to plus to 5 degrees celsius range. This will result in high temperatures Tuesday to be in the lower to middle 50s. with a more amplified/broad upper level ridge working over the region for the weekend.
1255 PM EST Mon Nov 7 2016 High pressure will build over the area through Tuesday.
306 PM EST Mon Nov 7 2016 High pressure will be in control of the weather through Tuesday bringing clear skies and light winds.
215 PM CST Mon Nov 7 2016 Positively tilted short wave digging southeast from the Midwest will approach the region with an associated cold front Tue/Tue night. A broad area of high pressure will build east into the Ohio Valley region for much of the rest of the short term, keeping all areas dry but cooler.
257 PM CST Mon Nov 7 2016 Upper-level trough bringing rain today will be the only source of sensible weather through the next 7 days. Subjective 12Z upper-air analysis indicates 500mb trough axis through the heart of ND/SD/NE/KS and toward the OK-TX panhandles. Short-range models are persistent in dissipating shower activity as it moves into eastern NE this evening, with upper-level trough weakening and elongating and mid-level moisture veering southeastward.
The main weather feature of interest in the short term is a cold front that will move southeast across our region on Tuesday. Ahead of the front, temperatures will reach the lower and mid 70s today. The accompanying cold front will move southeast across the Lower Ohio Valley in the afternoon.
303 PM EST Mon Nov 7 2016 High pressure will persist across the region into the middle of the week.
Cloud cover will gradually increase tomorrow from west to east ahead of an approaching cold front.
1232 PM EST Mon Nov 7 2016 High pressure will prevail through Tuesday keeping the region dry. The next chance for rain will be on Tuesday as a cold front sweeps across the area. High pressure will build quickly back in the region and dry weather will return. Mostly clear skies with calm winds prevail over the region as high pressure at the surface with ridging aloft builds over the region. The ridge will shift east today and generate strong WAA over the region. Monday night temps will be fairly chilly as strong radiational cooling takes places and temps fall into the low 30s to mid 20s. With the strong WAA sfc temps will rise into the low to mid 60s.
Highs today in the lower to mid 70s still look reasonable. Models have initialized well and are in good agreement, showing the upper level ridging weakening through tomorrow afternoon when weak vort max moves across the area.
A high pressure ridge will keep the air mass dry and stable.
133 PM MST Mon Nov 7 2016 High pressure will remain in control through the middle of this week.
The smoke should begin to disperse tomorrow evening, as winds shift to the southwest and then west and northwest and increase in speed as a cold front approaches and eventually moves through the area.
240 PM CST Mon Nov 7 2016 An upper level low pressure system over the Central Plains today will remain cut off from the main flow and drift southwestward over the next several days. High pressure should rebuild behind the front with a return to dry weather and slightly cooler temperatures.
1154 AM CST Mon Nov 7 2016 /18Z TAFS/ The main concerns with regard to aviation over the next 24 hours will be thunderstorm chances and low clouds following a cold front. /issued 436 AM CST Mon Nov 7 2016/ (Today and Tonight) An unsettled pattern will continue during the next 24 hours as an upper level trough remains over the area. Also, clouds will break up some this afternoon and allow some instability to take place across the eastern 1/2 of the area and combines with low level moisture, dewpoints in the lower to mid 60s.
257 PM EST Mon Nov 7 2016 High pressure will build over the area through Tuesday.
245 PM EST Mon Nov 7 2016 A ridge of high pressure at the surface and aloft will remain over the region through Tuesday.
202 PM EST Mon Nov 7 2016 A large area of high pressure will slowly recede off to the southeast overnight and Tuesday.
101 PM EST Mon Nov 7 2016 High pressure brings a stretch of dry weather through Tuesday.
1038 AM MST Mon Nov 7 2016 High pressure will remain in control of the weather for southeast Wyoming and Nebraska Panhandle through the upcoming week.
As the low-levels cool tonight, we expect fog to develop across most areas. The fog should begin to dissipate by mid-morning as a cold front moves in from the north. The cold front will continue to move southward Tuesday night and with drier air filtering in to the low-levels, rain chances will be on the decrease.
A cold front will move through the terminals tonight and moisture will increase rapidly behind it. A cold front will move into the are this afternoon, and through all terminals by 08/03Z. Clouds and a few showers may stick around across the eastern Permian Basin where cooler temperatures reside. A cold front will arrive early Tuesday morning with gusty northerly winds and much cooler conditions. Meanwhile, a ridge will build over the top of this system and keep it nearly stationary to our southwest for several days. Models have come into better agreement with the placement of the low, but differ in their amount of moisture and precip across our region.
High pressure will bring dry and warm weather over the next several days.
The smoke should begin to disperse tomorrow, as winds shift to the southwest and then west and increase in speed as a cold front approaches the area.
311 PM EST Mon Nov 7 2016 High pressure will extend into the region from the north through Tuesday.
348 PM EST Mon Nov 7 2016 High pressure will prevail through Tuesday keeping the region dry.
131 PM CST Mon Nov 7 2016 The upper trough over the Central Plains this morning will split apart with some of the energy moving NE and some of it retrograding back to the SW.
310 PM CST Mon Nov 7 2016 Reinforcing cold front will move into the Texas and Oklahoma Panhandles this evening and overnight, with increasing wind speeds.
259 PM EST Mon Nov 7 2016 High pressure centered across the northeast states will move southward and weaken. Meanwhile a cold front will move southeast across the Great Lakes on Tuesday and through the region Tuesday evening.
243 PM EST Mon Nov 7 2016 Dry high pressure will will persist over the area through Tuesday.
353 PM EST Mon Nov 7 2016 High pressure will be situated east of the area overnight and Tuesday allowing for southerly flow. A cold front will move through Tuesday evening and Tuesday night. This will allow for warmer temperatures overnight tonight than last night. Lows overnight will generally be in the low to middle 40s except for some upper 30s east of Columbus. Southerly flow will pick up on Tuesday in advance of a cold front that will move through Tuesday evening into Tuesday night.
1016 AM CST Mon Nov 7 2016 Mid and high level clouds along with the isolated light showers in the east this morning will continue to move east with the upper level low pressure trough axis. Surface and upper trof passing overhead this AM. A low level jet continues to result in gusty winds for the coteau, though these winds will continue to weaken as the trof passes through and the direction becomes more northwesterly. High pressure moves overhead for Tuesday.
1158 AM EST Mon Nov 7 2016 High pressure will be in control of the weather through Tuesday bringing clear skies and light winds.
The upper trough currently over the region will move off to the east tonight.
1234 PM EST Mon Nov 7 2016 High pressure centered across the northeast states will move southward and weaken as a cold front moves across the Great Lakes on Tuesday. High pressure will then settle across the central and southern Plains.
1055 AM MST Mon Nov 7 2016 Upper trough which brought some precip to parts of the region yesterday was located over western Kansas. As the trough continues to move east, surface flow over the plains will take on a northerly component as a weak cool front moves south. Max temps today will be a bit cooler than yesterday, with highs generally topping out at around 70F along the lower ark rvr valley and L/M60s on the divides. Min temps will continue well above normal with lows remaining above freezing across nearly all of the plains, with lows mainly in the mid 30s, and 20s in the SLV.
1201 PM EST Mon Nov 7 2016 High pressure will crest over the area through Tuesday.
Deep but fairly progressive upper trof continues to make its way across the Great Lakes, with the trof axis progged to reach the East Coast by Friday morning. Cloud cover will stick around the longest in the Bluegrass region, where temps will struggle into the mid 30s, while south- central Kentucky is able to punch solidly into the lower/mid 40s. Expect temps to quickly drop to around freezing on Friday evening, but then slowly rise toward daybreak Sat.
224 PM CST Thu Dec 29 2016 Northwest winds will continue into the overnight hours as high pressure continues to build into the region. Tomorrows high temperatures will be a couple degrees above todays as the flow becomes more southerly and the ridge axis moves over the forecast area. Ridging Friday night will quickly move off to the east in the fast zonal flow as another weather system moves quickly into the area for the first part of the weekend.
/issued 1025 AM CST Thu Dec 29 2016/ Cooler air continues to flow into Oklahoma and north Texas this morning. /issued 444 AM CST Thu Dec 29 2016/ The cold front has moved through bringing a slightly cooler, albeit still seasonable, airmass.
Ended up dropping the light snow area a little further southward, but the higher snow totals should remain over the far northern Red River Valley over toward the Lake of the Woods and the Upper and Lower Red Lakes, where 2 to 4 inches, and maybe even 5 are possible. The strongest winds look to remain over the higher elevations west of the Red River Valley, but they could easily translate into the valley and a little further eastward as well.
Models show an upper ridge to move into Colorado and flatten tonight into Friday. The low level pressure and wind fields point to fairly normal diurnal winds patterns, maybe favoring a bit of downsloping. This is more the case over the high county and foothills as cross sections show a bit of mountain wave set tonight into Friday. For temperatures, Friday's highs look to be 4-8 C warmer then this afternoon's highs. A series of lows will move into the region bringing cooler temperatures and a chance of snow to the region.
The winds at Devils Lake have already lost the higher gusts. With good push of warm advection ahead of the low, temperatures could be tricky so will stay consistent with inherited temperatures.
Model soundings and guidance continue to indicate mainly liquid precipitation, however a combination of evaporational cooling as well as upslope flow could result in conditions favorable for freezing rain, mainly across higher terrain from the Guadalupe Mountains south to the Davis Mountains late tonight into early Friday. However, a light glaze of ice due to freezing rain may be possible, particularly on bridges and other elevated surfaces. Friday will be another cool day, with highs again in the 40s and 50s, and rain chances Friday morning confined mainly across the Lower Trans Pecos, Stockton Plateau, and Big Bend Area.
139 PM MST Thu Dec 29 2016 19Z water vapor imagery indicated northwest flow across the Tri- State area with short wave ridging in place across the northern rockies. Main concern through the afternoon will once again be fire weather as dry layer aloft has been mixing down much drier air allowing dewpoints to fall into the lower single digits. weather will remain quiet through Friday with temperatures warming into the low 60s by tomorrow afternoon.
High pressure was analyzed across the intermountain west and should slide towards the southeast through the afternoon and overnight hours. High pressure is expected to slide close enough to the Metroplex and Waco TAF sites such that a 3-5 hour window of variable winds are expected Friday morning. Thereafter, persistent southerly flow should develop in response to the deepening Colorado trough.
254 PM CST Thu Dec 29 2016 Analysis of 12z upper-air data and early-afternoon water vapor imagery indicate the amplification of a broad-scale trough across the eastern half of the nation. In the low levels, strong gradient flow on the backside of the synoptic- scale trough to our east has yielded breezy conditions today, especially across our eastern counties. On Friday, considerable low-level warm advection is forecast ahead of a cold front which will begin to move into the northern part of the forecast area by evening. Abundant sunshine coupled with the low-level warming will boost afternoon temperatures into the 50-55 degree range over our western counties with 45-50 degrees in the east. The cold front will advance southeast through the mid Missouri Valley Friday night with gusty northwest winds developing in it's wake.
Northwesterly flow aloft will be decreasing and turning westerly through tonight as an upper ridge moves in from the west coast. Warm advection will allow for slightly warmer temperatures today, however much lighter winds may keep some low lying spots and areas with snow cover similar to or even slightly cooler than yesterday. Warm weather Friday likely followed by a harsh return to cold Friday will quite warm in most areas with warm advection aloft, strengthening lee trough, and downslope warming. By tomorrow night, a cold front is still on track to push across the plains bringing a surge of somewhat cooler and more moist low level air.
958 AM PST Thu Dec 29 2016 Light snow is expected to develop today as a weak warm front moves across the region. The threat and intensity of the snow will increase tonight and early Friday as a cold front pushes across the region. however expect this to pick up overnight after 4PM as the cold front begins to sag south. /sb 12Z TAFS: Main feature this morning will be a weak warm front and the precipitation it is expected to produce. The band of precipitation along this warm front is fairly narrow and should impact EAT MWH GEG SFF and COE between now and 16z before it moves north of these locations. After the front moves north confidence is good that all sites will be VFR until cold front moves in after 00z.
211 PM MST Thu Dec 29 2016 An upper level ridge over the area has been keeping the weather dry today and has resulted in relatively light winds in most locations. The upper ridge will be flattened over the area tonight as an upper trof moves into the Pacific NW and the northern Rockies. At the same time an upper low will move to just off the southern CA coast. Westerly breezes tonight near the mtns should keep temps relatively warm, while other areas without wind tonight will be a littler cooler. On Friday, the flow aloft will be westerly and the mountains, the lower east slopes and the I-25 corridor will likely see some breezy conditions in the afternoon. Temps will generally be warmer on Friday, with the southeast plains seeing the biggest increase in temps over today.
Temperatures are in the lower 80s with dewpoints near 70. This morning's sounding (12Z KKEY) sampled light winds through the lower troposphere. The mid-latitude cyclone currently swinging into New England has led to rising heights from the southern Plains to the Canadian Rockies (see 12Z plan view RAOB analyses). The sharpening ridge in the wake of the mid latitude low supports a developing high pressure dome centered near the panhandle of Texas. This high has an artic tap on its eastern flank. The strengthening high pressure system will spill southeast towards the Texas Gulf coast tonight, blasting a cold front across the Gulf of Mexico and through the Florida Keys Friday morning.
320 PM EST Thu Dec 29 2016 A cold front crossing the area today will move offshore this evening.
1217 PM CST Thu Dec 29 2016 Pacific high pressure centered over the Rockies moves into Texas today. the forecast shows 30 to 40 mph gusts with the higher speeds north. Temperatures are much cooler north with highs in the 30s where there is snow cover. a warm front currently across British Columbia will lift through Nebraska. New Year's weekend will be dry, but a cold front will surge south through the area late Friday night as an Alberta Clipper system crosses the northern plains.
945 AM PST Thu Dec 29 2016 Above normal highs today with weak high pressure aloft.
259 PM EST Thu Dec 29 2016 Accumulating snow is expected in the high terrain of Pennsylvania, West Virginia, and Maryland, as well as in the counties north of I-80, through Friday. With steep lapse rates and saturation to almost 650mb, a period of heavy snow is possible, especially in the high terrain overnight. In addition to the snow fall, gusty wind with deep mixing through the boundary layer will blow any new snow around, further deteriorating conditions over the high terrain. Snow showers will likely continue into the ridges through early friday night with saturation remaining in the dendritic growth zone, but accumulating snow should end.
/issued 446 AM CST Thu Dec 29 2016/ (Today and Tonight) Look for much cooler temperatures for the next 24 hours. Another cold front continues to push south across Texas this morning. This front will produce winds from the north today, along with much cooler afternoon highs, mainly in the lower to mid 50s. However, cloud cover and light winds should help maintain lows above the freezing mark tonight.
Have shaded to the low end of guidance. Have bumped the highs tomorrow for the central into east central mo where the light southwest wind will kick in faster.
At the surface, high pressure will continue to drift off to the East allowing low pressure to shift out of the Plains into the Upper Midwest. A weak warm front associated with the low will move across the forecast area during the day on Friday. Soundings indicate some mid and high level moisture which will produce some clouds tomorrow but there will be too much dry air in the lower levels to expect precip. Our main sensible weather reflection with this system will be a weak cold frontal passage leading to slightly cooler temperatures for the weekend.
1125 AM CST Thu Dec 29 2016 Today-Friday: Brisk northwest winds anticipated today will become light downslope tonight as high pressure builds in the region.
/Issued 1105 AM EST Thu Dec 29 2016/ A cold front oriented SW to NE, draped just south of metro ATL east to Athens will continue to march south. Temps much cooler Friday but still only a few degrees below average for this time of year.
1105 AM EST Thu Dec 29 2016 A cold front oriented SW to NE, draped just south of metro ATL oeast to Athens will continue to march south. Temps much cooler Friday but still only a few degrees below average for this time of year.
1014 AM MST Thu Dec 29 2016 Clear skies and generally calm conditions are being reported across the forecast area this morning as a ridge of high pressure temporarily resides over the Western CONUS. Under these conditions current temperatures are running in the low to mid teens in the high country and low to mid 20s in the lower elevations. Mostly clear skies will allow temperatures to climb into the mid 20s to mid 30s in the high country and mid 30s to lower 40s at lower elevations this afternoon. The current satellite water vapor image is showing a ridge of high pressure positioned over the Western CONUS with a cut off low centered off of the Southern California coast.
1122 AM EST Thu Dec 29 2016 An upper level trough will allow for snow showers across the area today into Friday.
Low pressure over the Great Lake and eastern Canada will dominate Indiana weather into Friday, when high pressure should take over.
An upper level trough and vorticity associated with it will move into the area today. Looking at the latest model soundings, these showers will likely start off as a mix of rain/snow as sfc temps will be in the lower 40s this afternoon and moisture may not be quite deep enough to produce many ice crystals. Again, very little if any snow accums are expected from this upper trough, but if timed correctly could result in a few slick spots for the Friday morning commute. Temperatures today should top out in the low to mid 40s.
High pressure is currently centered over the Oklahoma Panhandle at this time. The high is forecast to move southeast into North Texas tonight. Temperatures will be seasonably chilly with lows Friday morning mainly in the lower 30s. On Friday, the high will scoot to the east and reach central Alabama. Temperatures will remain seasonal with highs in the low to mid 50s. By Friday night, a cold front will start to approach the region from the northwest.
