342 PM CDT THU AUG 11 2016 Big changes in store for the area as a cold front approaches the area tonight/tomorrow. This cold front extends this afternoon from NE through western KS and will bring cooler weather and a focus for showers/thunderstorms through the weekend.
310 PM EDT THU AUG 11 2016 High pressure will remain to the east through the week.
A cold front now over the central High Plains will continue to move southeast toward the area this evening. As instability wanes overnight, some deintensification should occur although we have kept chances fairly high through the morning and confined the highest chances to the afternoon and evening as instability increases once again. Prior to outflow/cold front and or convective development, southeastern portions of the area should be able to reach Heat Advisory criteria. Cooler weather will arrive behind the front with mid to upper 80s common through early week.
330 PM CDT THU AUG 11 2016 Cold front extended from northern WI to nw KS with dewpoints south of the front in the mid to upper 70s with temperatures in the 80s and 90s. With the low level jet in place, combined with a short wave arriving from the west, and a cold front approaching from the northwest, this brings the decent forcing to trigger the thunderstorms. The storms will gradually diminish on Friday as the cold front sags southeast across the cwa. Lows tonight will be in the lower 70s with highs on Friday in the lower to mid 80s. Highs will be in the lower to mid 80s with lows in the lower to mid 60s. This will be ahead of a slow moving cold front that will push across the area on Friday.
The general synopsis this morning shows a cold front extending from southeast SD through southwest NE. The warm start will lay the groundwork for a very hot day as there has been warm advection in the past 12 hours and temperatures will start out a few degrees warmer than yesterday so expect highs to be 1-3 degrees warmer than yesterday for the majority of the forecast area. Late this afternoon into the evening, the cold front will push into the local forecast area with a slow southward progression through the overnight hours. A short wave trough will move across KS from the southwest this evening as well and appears likely to enhance moisture influx and convergence locally by late evening into early morning.
400 PM CDT THU AUG 11 2016 A cold front extends from around Ord down to Lexington late this afternoon.
Building high pressure will result in a warming trend over the next several days with inland temperatures reaching the triple digits.
914 PM EDT Fri Mar 31 2017 Low pressure and trailing cold front will move off the Mid Atlantic coast tonight.
1225 AM EDT Sat Apr 1 2017 Rain chances should end this morning as low pressure exits.
710 PM EDT Fri Mar 31 2017 A cold front will move through Eastern North Carolina this evening. High pressure will pass through from the northwest this weekend.
20z water vapor imagery shows high level clouds already entering western Iowa, which are associated with a piece of mid-level vorticity that ejected from this low. Given more filtered sunshine over northeastern Iowa, afternoon temperatures will be the highest there with readings approaching 60 degrees.
740 PM EDT Fri Mar 31 2017 A cold front moves through tonight.
/Issued 411 PM CDT Fri Mar 31 2017/ Ridge of high pressure continued to move through the Plains this afternoon as a closed low pressure system was making its way east southeastward near the Four Corners region. Underneath this ridge. High pressure shifts eastward overnight tonight with breezy southeasterly winds and warmer temperatures returning across the CWA Saturday. The upper low will continue to make progress across New Mexico during the day Saturday with thunderstorm potential developing across Western Oklahoma.
939 PM EDT Fri Mar 31 2017 Low pressure over Ohio will shift east across Pennsylvania this evening and then off the New Jersey Coast after midnight. High pressure will build into the Ohio Valley and Lower Great Lakes on Saturday.
Stacked low pressure system continues to move through the Ohio Valley heading toward the Atlantic coast. But for the moment, still getting some nuisance mid-level FGEN forced light precip stretched across the SE part of the CWA, as well as some drizzle/flurries through the higher terrain. Dry and substantially warmer on Saturday with temps ranging from the mid 40s to the mid 50s, although cloud cover does increase again through the day with a weak cold front dropping in the from the north.
749 PM EDT Fri Mar 31 2017 Low pressure over Ohio will shift east across Pennsylvania this evening and then off the New Jersey Coast after midnight. High pressure will build into the Ohio Valley and Lower Great Lakes on Saturday.
946 PM MST Fri Mar 31 2017 A cool low pressure system will continue to slowly circulate through northern Arizona tonight, and slowly exit into New Mexico Saturday.
705 PM CDT Fri Mar 31 2017 cold front and leading oedge of lower clouds moving southeast thru the fcst area at 00z. Some patchy fog potential in the lower level moisture regions of NE ND and NW MN overnight/Sat AM. Challenge for the evening into Saturday will hinge on cloud cover, light showers and fog as a weak cold front drops south across the forecast area. As the cold front pushes south across the forecast this evening 925MB CAA on northerly winds will push south stalling across the southern valley towards morning.
522 PM MDT Fri Mar 31 2017 Large upper low crossing the Four Corners region will continues its slow eastward drift tonight through Saturday. Inverted trough across the central high plains will continue to bring precip to the region. Any precip reaching the higher Black Hills will fall as snow. This will bring in warmer air with temps reaching the 50s to low 60s Saturday. The cooler spots will be across SW/SCentral SD where clouds will take longer to erode.
1020 PM EDT Fri Mar 31 2017 A cold front moves through tonight.
The periodic pattern and transition from ridge to trough (or closed low) back to ridge weather features will continue into early April. The next chance for measurable precipitation will be delayed at least 50 hours, as the building ridge over the Quad State region tonight gradually phases in with the northern stream ridge in Central Canada. The exiting low pressure center in the Northeast U. is slowly being followed by another closed low approaching the four corners region of the Desert Southwest U. low, forcing the low to open and accelerate eastward.
752 PM EDT Fri Mar 31 2017 Low pressure and trailing cold front will move off the Mid Atlantic coast tonight.
An upper level low is moving across the DELMARVA coast at this hour.
Surface analysis this afternoon shows an area of low pressure over the eastern Ohio Valley region with another area of low pressure near the 4-Corners region. In between, for much of the central CONUS, resides weak high pressure. Aloft, similarly placed upper level lows linger in the eastern and western portions of the CONUS while generally zonal flow exists from southwestern Canada into the Great Lakes. As the center of the weak high pressure shifts eastward, this will allow weak easterly winds to become more south and southwest, thus allowing for modest warm air advection to develop for tomorrow. As such, will look for highs tomorrow to be roughly 5-10 degrees warmer tomorrow than what was experienced today, particularly since no low clouds are expected tomorrow.
MVFR to IFR conditions will dominate forecast mainly across northwest Oklahoma terminals but development of at least MVFR restrictions expected mainly over terminals from KHBR/KCSM and KOKC northward Saturday morning, being on northern periphery of developing warm front. An upper level low/trough over Arizona will move slowly to the east over the weekend.
High pressure will keep mostly clear sky over our forecast area tonight. The ridge will flatten on Saturday as a short wave rides over. We will also see a thermal trough developing and this will lead to gusty north to northeast at the coast and the coastal range.
Cirrus will begin to return areawide on Saturday ahead of the deep upper trough out west along with some CU around 4Kft during the afternoon hours. /issued 451 PM CDT Fri Mar 31 2017/ For the Four State Region another night of cool weather will prevail with warming temperatures on Saturday with the Southerly flow aloft becoming more pronounced as ridging of high pressure aloft moves overhead and to the East.
An upper low centered over northeast Arizona will slowly exit east into New Mexico tonight.
925 PM EDT Fri Mar 31 2017 A cold front will exit off the coast overnight.
740 PM EDT Fri Mar 31 2017 Low pressure will deepen over the Chesapeake Bay this evening and pull away to the east overnight.
1041 PM EDT Fri Mar 31 2017 Low pressure located near Cape May this evening will push off the coast later tonight.
Today has been a cooler and pleasant day across the Tennessee Valley. This clearing trend should continue tonight and into Saturday as upper ridging and northerly surface winds allow at least a couple of days of drier weather.
An upper low centered over northeast Arizona will slowly drift south along the Arizona and New Mexico border tonight.
838 PM EDT Fri Mar 31 2017 A cold front will sweep east across the area this afternoon and evening. High pressure will then build into the Mid-Atlantic and Southeast through the weekend.
1056 PM CDT Fri Mar 31 2017 Ridge of high pressure building in from the Northern Plains/southern Canada was slowly eroding stratocumulus cloud cover from north to south across the forecast area. Some increase in high/mid clouds then expected through the early morning hours ahead of a trough of low pressure dropping through the Northern Plains. Plan on lows tonight ranging from the middle/upper 20s across central WI, to the lower/middle 30s along and west of the Mississippi River. Mid-level trough continues to drop southeast through the region Saturday for some patchy mid/high cloud. Will be watching some moisture return from the Central Plains later Saturday night ahead of a closed low moving out into the plains of Colorado.
Cold front located from Brunswick Ga to near Live Oak Fl will push southward overnight and be just south of the area by 12z Sat. Cold front will cross area waters tonight, followed by building high pressure through the weekend.
1205 AM EDT Sat Apr 1 2017 IFR ceilings will lift slowly to MVFR overnight into Saturday morning and then scatter out to VFR by midday as drying northwest flow of 10-12 knots continues to feed into area in advance of building high pressure. This high will settle over area Saturday night and bring generally clear conditions and light winds by the end of the forecast period. If the low clouds (clearing from northwest to southeast) occurs a couple hours before sunrise (Tri-Cities Region), could see fog development, as advertised by 12z NAM CPD's. Saturday morning clouds (likely along/south of I-69) will dissipate as diurnal mixing helps speed up the process from north to south, and afternoon 925 mb temps of 5 C points to highs in the lower 50s, as some insolation is used up drying the moist/saturated ground.
1256 AM EDT Sat Apr 1 2017 High pressure will begin building into the region tonight and will continue through the weekend.
Challenge for the evening into Saturday will hinge on cloud cover, light showers and fog as a weak cold front drops south across the forecast area. As the cold front pushes south across the forecast this evening 925MB CAA on northerly winds will push south stalling across the southern valley towards morning.
1156 PM CDT Fri Mar 31 2017 VFR is already deteriorating ahead of schedule near PVW as a cold front arrives with more gusto. /issued 1047 PM CDT Fri Mar 31 2017/ Updated the forecast through Sat to account for a more aggressive cold front that is now favored to stall near or south of Highway 380 by midday.
1114 PM EDT Fri Mar 31 2017 Low pressure located near Cape May this evening will push off the coast later tonight.
These clouds would only affect the far southeast for several more hours until the low level winds turn more northerly. Still expect drying in the low levels to prevent significant fog from developing overnight. High pressure over MN will then reach wrn WI by Sat AM and gradually move across srn WI through Sat.
913 PM EDT Fri Mar 31 2017 Clouds continue to stream across the forecast area around upper low over northeast KY this evening. Light showers will end in the next few hours over extreme northeast Tennessee and southwest Virginia as precipitation moving around upper low shifts to the east.
620 PM CDT Fri Mar 31 2017 Low cloud coverage remains over the area as remnants of the cut off low pressure system that came through this week. These clouds are expected to stick around over night keeping our low temperatures from dropping much with lower 40s expected with the low clouds starting to erode in the afternoon. A finger of the low level jet will advect into the area Saturday night creating enough warm air advection and isentropic lift to develop some rain showers and isolated thunderstorms along the nose of this feature.
The low ceilings should slowly lift through the morning hours and raise above 3000 ft around midday Saturday. The better rain and thunderstorm chances will begin west of the TAF sites Saturday afternoon with the approach of a dryline and upper level low. /ISSUED 346 PM CDT Fri Mar 31 2017/ An upper level low currently over Arizona this afternoon will be the big weather maker for this weekend.
635 PM CDT Fri Mar 31 2017 Ridge of high pressure building in from the Northern Plains/southern Canada was slowly eroding stratocumulus cloud cover from north to south across the forecast area. Some increase in high/mid clouds then expected through the early morning hours ahead of a trough of low pressure dropping through the Northern Plains. Plan on lows tonight ranging from the middle/upper 20s across central WI, to the lower/middle 30s along and west of the Mississippi River. Mid-level trough continues to drop southeast through the region Saturday for some patchy mid/high cloud. Will be watching some moisture return from the Central Plains later Saturday night ahead of a closed low moving out into the plains of Colorado.
1011 PM EDT Fri Mar 31 2017 Low pressure and a trailing cold front will move well east of the Mid Atlantic coast tonight. High pressure builds over the area for the weekend.
736 PM EDT Fri Mar 31 2017 High pressure building into the area tonight will prevail through the weekend.
940 PM PDT Fri Mar 31 2017 Mostly clear and mild this weekend with high pressure building aloft.
539 PM MDT Fri Mar 31 2017 Upper low currently over northern Arizona will wobble slowly to northern New Mexico by Saturday afternoon. Vorticity lobe rotating around the main upper low will provide synoptic scale lift for precipitation, which will overspread the area from southwest to northeast tonight. Saturday night: Upper low will continue to transition eastward with rain/snow activity ending west to east with best chances still in the evening period.
945 PM EDT Fri Mar 31 2017 Frontal trof has reached the I-4 Corridor and will continue to work its way thru the CWA overnight. Forward momentum will diminish, however, as the parent low lifts into New England, while a weak post frontal ridge, sandwiched inside an H30-H20 jet min, spins in place over the Lwr MS Valley. Gentle to moderate W/SW breeze will diminish to a light to gentle W/NW breeze by daybreak as the lcl pgrad slackens with the passage of the frontal trof.
Still expect drying in the low levels to prevent significant fog from developing overnight. High pressure over MN will then reach wrn WI by Sat AM and gradually move across srn WI through Sat.
1001 PM EDT Fri Mar 31 2017 A cold front will move through Eastern North Carolina tonight. High pressure will pass through from the northwest this weekend.
747 PM EDT Fri Mar 31 2017 Upper low moving across northeast KY this evening still generating a few very light showers over NE TN but do not expect these to be that significant so dropped showers. More significant will be the lower clouds across all of east TN. Clouds decrease Saturday as ridging aloft replaces upper low.
1025 PM EDT Fri Mar 31 2017 Forecast on track for this near term as high pressure continues to build in and mostly clear skies prevail aside from far north GA with lingering stratocu. this is not an April Fools joke! It will be beautiful with light west winds and temperatures rebounding into the mid 60s across the higher elevations to around 80 across central GA.
patches of fog possible near KBKE and KMYL and in the higher mtn valleys.
1156 PM CDT Fri Mar 31 2017 Low cloud coverage remains over the area as remnants of the cut off low pressure system that came through this week. These clouds are expected to stick around over night keeping our low temperatures from dropping much with lower 40s expected with the low clouds starting to erode in the afternoon. A finger of the low level jet will advect into the area Saturday night creating enough warm air advection and isentropic lift to develop some rain showers and isolated thunderstorms along the nose of this feature.
801 PM EDT Fri Mar 31 2017 Low pressure will continue to move toward the southern New England coast tonight.
637 PM CDT Fri Mar 31 2017 A mid/upper ridge was moving over the central Conus while low clouds and below normal temperatures remained entrenched across the forecast area. A warm front may lift north across the Oklahoma state line into Southern KS on Saturday but temperatures north of the front will likely remain below normal once again with moist upslope flow and limited insolation.
1038 PM EDT Fri Mar 31 2017 High pressure building into the area tonight will prevail through the weekend.
722 PM EST Wed Dec 21 2016 High pressure over the region will weaken and move south of the area overnight. A weak and dry cold front will move through the area late Thursday.
High pressure will then track across the Central Plains on Thursday shifting winds around to the southwest.
558 PM CST Wed Dec 21 2016 Initial forecast concern will be closed cyclone off the coast of Baja California as it tracks northeast over the next 36 hours. Clouds will be on the increase during the day on Thursday ahead of this system, but with bare ground and a southwest wind we should see highs again climb into the lower to middle 40s despite the clouds.
High pressure remains over the Southeast with weak low level winds. Lows will be in the low 40s in the eastern half of the region and high 40s in the western half where cloud cover is greater.
Upper troughing behind the front, combined with some lake enhancement, could result in a few snow showers mainly N of PIT Thursday. Maintained the low chance pops in the mentioned area.
918 PM CST Wed Dec 21 2016 Cold front continues to push through far southeast OK this evening with light north winds in most places behind the front. Cold front, currently located south of a ICT/MCI line will move into northeast Oklahoma shortly with front quickly sweeping south to the Red River by late evening. Upper low currently off the southwest CA coast will begin to lift northeast across the desert southwest on Thursday.
Cooler temperatures behind a weak cold front are starting to filter into the Oklahoma Panhandle. The upper level low we've been watching in the Pacific will begin moving into Baja tomorrow morning, and moisture from this system will approach the Panhandles. Surface temperatures will start out in the upper 20s to low 30s, and it may take some time for the lower levels to moisten up overnight. Further east, P-type becomes quite messy and complicated given the uncertainty of both surface temperatures warming to freezing or just above, and the strength of a warm nose intruding into the area.
851 PM EST Wed Dec 21 2016 High pressure will move offshore this evening. A dry cold front will move through the area Thursday afternoon.
606 PM EST Wed Dec 21 2016 A mid-level trough will move through the Great Lakes late night and Thursday, with a weak cold front moving through the Ohio Valley early Thursday.
The lower clouds have scattered out a bit late this afternoon. There could be brief LIFR conditions around daybreak as winds go nearly calm and moisture pools ahead of an approaching weak cold front. A cold front of modified maritime polar air mass characteristics will push south into Central Texas tonight however, slowing by the time it reaches the Ranchlands around midnight, and then pushing slowly through the area through Thurs.
Southwest winds will shift to the north this evening as a cold front moves through the area. The cold front is expected to be through KABI within the next few hours with the front through all terminals by 05Z. Tonight, a cold front will move through the area. Temperatures will fall into the 30s across the CWA, but temperatures will be noticeably cooler tomorrow. Temperatures will be cooler Thursday behind the cold front, with highs ranging from the upper 40s north of I-20 to the mid 50s along the I-10 corridor.
A cold front is progged to move through the area late tonight into Thu morning.
temps have warmed into the lower 70s thanks to downslope adiabatic warming. Could see some brief light freezing rain early around sunrise but will take a while to saturate top down across central and eastern sections of the South Plains.
Colder night on tap in the wake of the cold frontal passage. Relatively cool day with cloud cover, though temperatures will be above freezing.
Winds will be light and variable to south at 3 to 8 mph this evening, while overnight a cold front will move through the state and switch winds to the west to northwest at 5 to 15 mph.
907 PM EST Wed Dec 21 2016 High clouds were moving across central Georgia from the northwest, and the high clouds will continue to stream into southeast Georgia as they scatter out overnight.
525 PM CST Wed Dec 21 2016 A weak cold front/wind shift dropping through the region this afternoon is moisture starved and mostly cloud-free. In fact thanks to zonal upper flow, the airmass behind this front is more of Pacific origin so that temperatures tonight will actually be a few degrees warmer than last night.
525 PM CST Wed Dec 21 2016 Current VFR conditions are forecast to give way to predominately MVFR conditions during the overnight period with ceilings lower in advance of a cold front approaching from the north. The cold front will pass through the region from 11Z through 15Z resulting in a shift to northerly winds for the day tomorrow.
915 PM EST Wed Dec 21 2016 High pressure will continue to push off the east coast through tonight.
Winds will continue to be gusty tonight and beyond in the Livingston area as lee side troughing continues ahead of a Canadian low pressure system.
Low temperatures tonight will remain above freezing. Clouds will linger into tomorrow as a dry cold front moves into the region. so no freezing fog threat tonight for all areas. Models agree on an approaching cold front helping to maintain some cloudiness tonight and early on Thursday along and ahead of the front. clearing skies and a cooler airmass will bring freezing temps back to far north GA Thursday night.
Another dry and mostly sunny day is expected Thursday as upper ridge axis crosses the region. Upper low will weaken into an open wave as it comes onshore early Thursday and transitions northeastward.
A large area of low pressure off the Baja Coast will continue to increase moisture over Arizona tonight with mild temperatures.
927 PM EST Wed Dec 21 2016 A mid-level trough will move through the Great Lakes late night and Thursday, with a weak cold front moving through the Ohio Valley early Thursday.
1022 PM EST Wed Dec 21 2016 High pressure over the region will weaken and move south of the area overnight. A weak and dry cold front will move through the area late Thursday.
637 PM EST Wed Dec 21 2016 Low pressure will swing into the region later tonight into Thursday with a period of light snow and minor accumulations.
