216 PM CST Wed Feb 15 2017 Low pressure in the Desert Southwest will slowly work its way across the Southern Plains, and be be approaching the Quad State by the week's end. Until then, we'll be sandwhiched between the backside of a long wave trof riding along the Eastern U. and surface to upper high pressure in the High Plains.
311 PM CST Wed Feb 15 2017 Little in the way of cloud cover expected through Thursday, with relatively light southerly flow shifting around to the west later tonight as a warm front moves east across the forecast area. The light winds and clear skies should allow for decent radiational cooling tonight, with lows a few degrees below freezing for most of the area.
1254 PM EST Wed Feb 15 2017 Low pressure moving into the forecast area this morning will merge with a cold front and move off the coast this afternoon.
124 PM CST Wed Feb 15 2017 Low pressure in the Desert Southwest will slowly work its way across the Southern Plains, and be be approaching the Quad State by the week's end. Until then, we'll be sandwhiched between the backside of a long wave trof riding along the Eastern U. and surface to upper high pressure in the High Plains.
308 PM EST Wed Feb 15 2017 In the wake of a low pressure system and cold front moving off the Mid-Atlantic coast, a secondary cold front will cross the area tonight.
223 PM CST Wed Feb 15 2017 An upper trough is over the northeast US with a portion of the trough lingering over northern Mexico. Upper ridging will be present over the central US with the previously mentioned lingering trough moving over southwest TX on Thursday.
High pressure will then build in for the beginning of the weekend with drier and warmer conditions expected. A deepening upper low projected to cross into New York this evening will reinforce colder air across the area. The combination of colder air with increasing moisture in the low levels will assist in generating more snow showers, especially across the favorable upslope terrain. Model soundings depict steep lapse rates through the snow growth zone with sufficient moisture overnight across the ridges of WV and MD. Given the quick breakdown of the inversion height as high pressure is progged to build late tonight, snow accumulation should overall remain below advisory criteria elsewhere. Building high pressure should end the snow showers later on Thursday and keep temperatures slightly cooler than average.
Fresh high pressure along the front range is 1026MB and if forecast to drift E overnight at 1022MB over Jena by this time tomorrow 15z.
There will be some occasional light freezing rain through midday and then surface temperatures will begin to warm above freezing. Some location along the east slopes of the Washington Cascades could see some freezing rain well into the afternoon before the warming occurs. Overnight temperatures are expected to remain near or above freezing so not expecting any freezing rain impacts overnight. Freezing Fog Advisory until 10 AM PST this morning for ORZ044- 507. Freezing Rain Advisory until noon PST today for ORZ041-044-507. Freezing Fog Advisory until 10 AM PST this morning for WAZ029. Freezing Rain Advisory until noon PST today for WAZ024-027>029- 521. Freezing Rain Advisory until 4 PM PST this afternoon for WAZ026- 520.
1153 AM CST Wed Feb 15 2017 High pressure continues to build over the area from the west. Lowered max temperatures in the far north a couple of degrees to the high 40s as they are slow to warm up this morning. with winds becoming light and variable overnight as high pressure settles across the state. Southerly winds will return for Thu as the high shifts east.
Northerly flow at the surface and clearing skies have allowed temperatures to fall to near freezing this morning across much of the area. Temperatures will climb to near normal with light winds as high pressure centers over Texas this afternoon.
A ridge of cold high pressure is settling into the forecast area this morning on the heels of yesterday's cold front passage. Highs today to get into the high teens and 20s for most locations, but probably the coldest day of this work week. Upper level ridging will start to impact the Northland starting Thursday night, with the upper level ridge remaining dominant into the first part of the weekend.
Warmer than normal temperatures continue tomorrow with highs ranging from upper 30s to upper 40s across the forecast area with winds in E ND turning to the west and helping mix down some warmer 10 to 12C 850mb air. Otherwise, models indicate strong warming as upper ridge develops over the area, and thickness values along with 850hPa temps of around 10C to 12C support the forecast reasoning. Therefore, it is not unreasonable to see daytimes highs in the low 40s in the north, with potential of hitting low 50s in the north as more open ground supports greater heating. The pattern appears to become a bit more active toward the end of the period with slightly cooler temps, but values are still expected to remain above seasonal norms.
819 AM PST Wed Feb 15 2017 A wet and mild storm system will bring a threat for freezing rain to Central Washington and rain in Idaho and Eastern Washington.
A low pressure system will move across the Southern Appalachian Region tonight.
941 AM MST Wed Feb 15 2017 Upper blocking pattern has set up across the western to central CONUS with upper ridging slowly building into the region. Strong surface ridging sits across the northern to central plains. Upper ridging will continue through the weekend.
1035 AM MST Wed Feb 15 2017 An amplified ridge over the Intermountain West continued to bring drying to the area overnight. Strong radiational cooling resulted in temperatures which were, on average, about 5 degrees cooler than the night before. The ridge axis will drift eastward today bringing a couple of degrees of warming at the 7H level. The same holds true for Thursday as the flattened ridge axis moves overhead bringing another degree of warming at 700 mb. However, GFS MOS does appear to be on point with sub- freezing highs in the Gunnison Basin as the stagnant, snow covered valley continues to radiate energy away tonight.
254 PM MST Wed Feb 15 2017 High pressure drifting eastward over the Desert Southwest will bring dry conditions and above-normal temperatures to the region through Thursday.
1133 AM CST Wed Feb 15 2017 Sharp ridge over the western CONUS between Aleutian low and upper low over the Great Lakes. Ridge extends over western Canada and north to the Arctic Circle. Strong upper level ridging across much of the western US will keep conditions dry across Nebraska through the end of the week and into the weekend.
321 PM CST Wed Feb 15 2017 Deep upper level trough was located across the Great Lakes region keeping the low stratus across lower MI and into the upper OH valley, under the cyclonic flow. This along with a very dry airmass and light to calm winds will allow temperatures to drop to the chilly levels, due to a weak ridge of high pressure over the area. Lows should range from the lower to mid 20s north to around 30 in our far southern cwa. Afternoon highs should range from the mid 40s at Freeport, IL to the lower 60s at Memphis, MO.
330 PM EST Wed Feb 15 2017 In the wake of a low pressure system and cold front moving off the Mid-Atlantic coast, a secondary cold front will cross the area tonight.
Guidance has generally been on the low side for temperatures recently. Expect that trend to continue for today and Thursday despite the arrival of a cooler air mass.
157 PM MST Wed Feb 15 2017 Upper ridge covers the western CONUS. With high pressure over the northern plains, skies are mostly sunny. The upper ridge will gradually move over the central states, with warm and dry weather continuing, along with mostly sunny skies and west-southwest surface winds.
Gusty north northwest winds this afternoon will relax this evening as high pressure builds further into the region.
1035 AM CST Wed Feb 15 2017 High pressure at the surface continues to build in from the northwest, resulting in dry airmass with near seasonal temperatures this afternoon, along with clear skies. Despite the low humidity and a modest north wind, which has locally gusted near 20 mph, yesterday's rainfall will provide a nice reprieve from recent fire danger.
325 PM EST Wed Feb 15 2017 High pressure will build in from the south tonight and Thursday.
Gusty east winds today, otherwise dry and warmer conditions the second half of the week. A stronger Pacific storm system will bring a very good chance of valley rain, mountain snow, cooler temperatures and gusty winds this weekend. The low that passed through us yesterday is now near southern Sonora and central Baja, serving to dirty up the base of a developing ridge as it loses higher latitude support. We'll see a warming trend with the larger scale ridge, but the easterly return flow will keep that from getting out of hand the next 2 days. Still on track for a stronger, windier, wetter, and cooler system to impact the area over the weekend.
Afternoon humidities down in the low to mid teens this afternoon. Warmest/windiest day will be Thursday as upper ridge axis moves east of the CWFA.
Many will see overnight lows fall into the upper 20s to right around 30 as high pressure settles into the region, skies clear and winds relax.
Clear skies and light winds overnight will be favorable for radiational cooling across the region, and lows can be expected to fall into the lower to mid 40s tonight. Conditions will warm slightly more on Thursday with the return of onshore flow, and highs will warm into the mid to upper 60s along the coast to the lowers 70s inland. Temperatures will continue on a warming trend into Thursday night, with lows staying in the lower to mid 50s overnight.
1018 AM MST Wed Feb 15 2017 Dry and warmer weather returns today as the upper ridge continues to nose over top east-west oriented trof across the southern U. Exception will be the San Luis Valley and southwest and central mountains where temperatures will be similar to a degree or two warmer. Should be warmer tonight along the lee of the mountains were lee troffing and some enhanced westerly drainage flow will continue.
Winds will be out of the southeast Thursday, so expect temps to remain cooler near Lake Michigan, in the mid 30s max. Well inland, sunshine and warm air advection will help temps warm into the lower 40s.
The model dewpoints have been too high with forecast soundings easily saturating in the low levels.
Fresh high pressure along the front range is 1026MB and if forecast to drift E overnight at 1022MB over Jena by this time tomorrow 15z. /issued 501 AM CST Wed Feb 15 2017/ Upper level trough continues to pull out of the region with plenty of wrap around moisture and low clouds still blanketing our CWA early this morning. This low cloud cover has resulted in areas of patchy light rain and drizzle persisting overnight and will carry this chance into the mid to late morning hours across most of our eastern zones. A warming trend will begin taking shape beginning Thursday with upper ridge setting up over the region.
149 PM MST Wed Feb 15 2017 Large scale ridging is in place across the Intermountain West extending eastward into the Central High Plains. At the surface lee troughing extending across eastern Colorado, with weak SW gradient extending over our CWA.
355 PM CST Wed Feb 15 2017 After a seasonable day today, warmer temperatures are expected tomorrow with a return to southerly winds and as a low-level thermal ridge develops across the Southern Plains.
/Issued 1035 AM CST Wed Feb 15 2017/ High pressure at the surface continues to build in from the northwest, resulting in dry airmass with near seasonal temperatures this afternoon, along with clear skies. Despite the low humidity and a modest north wind, which has locally gusted near 20 mph, yesterday's rainfall will provide a nice reprieve from recent fire danger.
Despite mostly sunny skies by this afternoon, ongoing (albeit weakening) cold air advection will result in many locations climbing only into the lower 60s today.
/issued Issued by National Weather Service Shreveport LA/ Water vapor imagery shows a trough of low pressure moving across the Eastern half of the US this morning. with the associated cold front pushing south along the gulf coast. cooler and drier air will filter into the region today. with temperatures running 10 to 18 degrees cooler today than those of yesterday. believe most areas will dip to around freezing tonight.
1155 AM CST Wed Feb 15 2017 High pressure will dominate over the area through the period with VFR conditions. (ISSUED 1153 AM CST Wed Feb 15 2017 ) High pressure continues to build over the area from the west. Lowered max temperatures in the far north a couple of degrees to the high 40s as they are slow to warm up this morning. with winds becoming light and variable overnight as high pressure settles across the state. Southerly winds will return for Thu as the high shifts east.
307 PM EST Wed Feb 15 2017 Lake effect snow shower activity will slowly wane late today into tonight as a ridge of high pressure builds east into the region. This trend will accelerate late tonight into Thursday as upper troughing shifts east and H85 temperatures warm substantially, especially to the west over Lake Michigan.
Winds should decrease with high pressure over the area. Despite mostly sunny skies by this afternoon, ongoing (albeit weakening) cold air advection will result in many locations climbing only into the lower 60s today.
