With temperatures in the lower to mid 80s and dewpoints in the upper 60s to lower 70s ahead of the line, a broken line of showers and thunderstorms developed within the last couple of hours along the frontal boundary.
A thin line of showers and thunderstorms will move across between 00Z-03Z as a cold front moves across the area. The cold front currently extends from northern Alabama to south central Louisiana, with numerous showers and embedded scattered thunderstorms occurring ahead of the front. This cold front will continue to move southeast at a 25 mph, and will move into the extreme northwest portion of our forecast area late this afternoon. Much cooler and drier air will follow in the wake of the front late tonight through Thursday.
720 PM EST Wed Mar 1 2017 A cold front will rush through the area this evening bringing much colder air with showers and isolated thunderstorms.
710 PM EST Wed Mar 1 2017 The advance of a strong cold front has brought showers and thunderstorms to the Upper Ohio Region for today. Much cooler temperatures will then last through much of the weekend. Strong low level lapse rates look to extend up toward the lower part of the dendritic growth zone simultaneously with the column supporting a changeover from rain to snow. Fries Cold advection within upper troughing should result in limited lake and terrain enhanced snow showers.
/issued 227 PM CST Wed Mar 1 2017/ A cold front has moved through most of the region this afternoon, with much cooler temperatures filtering into the area in its wake. Mostly clear skies will continue as the region remains under dry quasi-zonal to slight northwesterly flow aloft, and given light winds expected tonight, lows will be much cooler than the past several nights. Temperatures overnight will generally be in the low to middle 30s for most of the area, with upper 20s possible across northern Lea county and the Marfa Plateau, and lower 40s through Terrell county and the Rio Grande Valley.
1007 PM EST Wed Mar 1 2017 It will be warm and windy ahead of a cold front this afternoon. Dry and cooler conditions will follow the front for the end of the week. Showers and thunderstorms continue to push through the cwa ahead of a cold front moving through the region. Drying will occur behind the cold front Thursday.
937 PM EST Wed Mar 1 2017 Low pressure approaches from the eastern Great Lakes tonight and lifts across northern Maine early tomorrow morning. High pressure will build toward the area late in the weekend. A low over lake Erie, with an associated warm frontal system that extends east across Maine. The low will move east into southern Quebec early tomorrow morning, its associated cold front will move into western Maine. The low will track across northern Maine tomorrow morning, as the cold front moves into western New Brunswick. Low pressure will exit through the Canadian Maritimes Thursday night with sharply colder air expected to move back into the area on gusty northwest winds.
High pressure will settle over the southern Plains tonight. As the high moves off to the east, south winds will increase. A weak trough of low pressure will probably move into far northwest Oklahoma late in the afternoon on Thursday, causing another shift in wind direction.
Have made some adjustments to the forecast this evening given some lingering precip across the Lower RGV and coastal waters. The cold front has moved south of RGV late this afternoon. /issued 243 PM CST Wed Mar 1 2017/ SHORT TERM (Now through Thursday night):The weak cold front continues to drift southeastward across the region, and is passing through Cameron and Willacy Counties currently. The cooler airmass and drier air behind the front will allow temperatures to fall into the 50s tonight.
901 PM EST Wed Mar 1 2017 A cold front was moving across Georgia this evening with a line of showers and thunderstorms along it. Overnight lows are forecast to be in the mid to upper 50s across inland southeast Georgia, and near 60 to the lower 60s elsewhere.
551 PM CST Wed Mar 1 2017 For the 02/00Z TAFs, VFR conditions will dominate behind recently departed cold front. Otherwise, clouds will be limited to cirrus still lagging behind the cold front but SKC conditions are expected at all sites after 02/03Z. /issued 301 PM CST Wed Mar 1 2017/ The aforementioned cold front has finally moved through the entire region, leaving behind mostly sunny skies and gusty northwest winds near 20 mph with higher gusts. Its possible some overnight lows may fall to around the freezing mark north of the interstate 30 corridor over the next couple of nights.
638 PM EST Wed Mar 1 2017 The advance of a strong cold front has brought showers and thunderstorms to the Upper Ohio Region for today. Much cooler temperatures will then last through much of the weekend. Strong low level lapse rates look to extend up toward the lower part of the dendritic growth zone simultaneously with the column supporting a changeover from rain to snow. Fries Cold advection within upper troughing should result in limited lake and terrain enhanced snow showers.
Had to lower dewpoint temperatures several degrees as the airmass behind the cold front is drier than previously expected. /issued 551 PM CST Wed Mar 1 2017/ For the 02/00Z TAFs, VFR conditions will dominate behind recently departed cold front. Otherwise, clouds will be limited to cirrus still lagging behind the cold front but SKC conditions are expected at all sites after 02/03Z. /issued 301 PM CST Wed Mar 1 2017/ The aforementioned cold front has finally moved through the entire region, leaving behind mostly sunny skies and gusty northwest winds near 20 mph with higher gusts. e freezing mark north of the interstate 30 corridor over the next couple of nights.
732 PM EST Wed Mar 1 2017 A cold front will bring showers and thunderstorms late tonight.
MVFR visibilities are expected to improve to VFR within the next 1-2 hours and persist through the TAF period as increasing northerly winds behind today's cold front push residual moisture off the coast. /ISSUED Issued by National Weather Service Corpus Christi TX/ The cold front has moved through Southeast Texas and is currently along the coast and will continue eastward this evening and tonight. High pressure will build in from the north and keep breezy conditions along the coast and offshore tonight while inland areas should see winds decrease to lighter levels.
There will be a large difference in temperatures tonight between ridgetops and valleys due to a strong developing low level inversion. Believe most locations will fall below freezing (32F), except near the Red River east of Wichita Falls. High pressure will settle over the southern Plains tonight. As the high moves off to the east, south winds will increase. A weak trough of low pressure will probably move into far northwest Oklahoma late in the afternoon on Thursday, causing another shift in wind direction.
807 PM MST Wed Mar 1 2017 Updated forecast to extend the High Wind Warnings for the Bordeaux and Arlington areas until 11 PM late this evening. Flow aloft backs slightly to west northwest, inducing a more well developed surface lee trough and enough mixing to keep temperatures from bottoming out too much.
649 PM EST Wed Mar 1 2017 A line of showers and isolated thunderstorms blossomed along the cold front. Also updated the hourly temperatures, as readings have dropped off into the lower 50s behind the front, while some 60s hang on in far southeastern Kentucky. Main area of showers and thunderstorms has exited the state, but radar shows a few showers developing ahead of the approaching cold front. The cold front is on the door step of the forecast area at 3 PM. Much colder air will move into the area in the wake of the cold frontal passage this evening, with lows by Thursday morning in the lower to middle 30s. It will also be much cooler on Thursday with highs from 45 to 50.
445 PM MST Wed Mar 1 2017 Mostly sunny and cool conditions will continue rest of today through Thursday under a drier northwest flow aloft as a ridge of high pressure builds across the west. The exception to the mostly sunny conditions is the northern Park range where some light orographic snowfall is occurring at the higher peaks. Still adjusted through Thursday night towards the cooler side of guidance and a bit colder than guidance in the eastern most snow-covered valleys.
619 PM EST Wed Mar 1 2017 It will be warm and windy ahead of a cold front this afternoon. Dry and cooler conditions will follow the front for the end of the week. Convection continues to push eastward along and ahead of a cold front with some discrete cell convection starting to blossom over northeast GA and Upstate SC recently. Drying will occur behind the cold front Thursday.
/28/ Tonight and Tomorrow: As a cold front continues working southeastward through the forecast area this afternoon, some thunderstorms along the front have become strong to severe. A noticeably cooler night is then on order for tonight behind the cold front. Some locations may be as much as 20 to 30 degrees cooler than last night.
The cold front has moved south of RGV late this afternoon. /issued 243 PM CST Wed Mar 1 2017/ SHORT TERM (Now through Thursday night):The weak cold front continues to drift southeastward across the region, and is passing through Cameron and Willacy Counties currently. The cooler airmass and drier air behind the front will allow temperatures to fall into the 50s tonight.
Locally breezy east-northeast winds are developing as anticipated while high pressure builds into the Great Basin. A fair weather pattern will develop through the weekend as high pressure rebuilds over the west coast.
359 PM PST Wed Mar 1 2017 High pressure will remain in control of the forecast through Thursday night with frost forming tonight and then lasting through Thursday morning.
At lower elevations cross- sections continue to show a weaker stable layer and mountain wave that will continue gusting in the lower foothills from 25 to 28 mph into the early afternoon hours. Minimum temperatures tonight will be warmer than last night with the continued warmer foothills and urban corridor due to some downsloping pressure gradient still existing. Temperatures will be slightly warmer but the northwesterly flow will keep them cooler than average.
Meanwhile, weak upper level ridging is moving ashore off the Pacific into the Intermountain West. Near the surface, weak high pressure is shifting slowly east-southeast across the Texas Panhandle. With lighter winds and less near surface turbulence, the temperatures are likely to fall a few more degrees than last night, and as cold as the low teens in the higher terrain far western counties based on the various MOS output that is colder than the models.
Warm and dry again on Thursday as a weak ridge builds over the Intermountain West.
A ridge positioned over the PacNW will keep skies mostly clear for the rest of today. Tonight, clear skies will help patchy fog and freezing fog form in west side valleys. The ridge will begin to push eastward tomorrow afternoon, and we will transition to a more progressive pattern.
/issued 347 PM CST Wed Mar 1 2017/ The cold front has moved through the area and we will begin transition to a colder high pressure system for the next couple of days. As an upper level trough moves to the east.
The cold front has pushed through the forecast area this evening and all associated showers and thunderstorms have exited as well. Skies will be clear overnight with high pressure pushing into the region at the surface. /28/ Prior discussion below: Tonight and Tomorrow: As a cold front continues working southeastward through the forecast area this afternoon, some thunderstorms along the front have become strong to severe. A noticeably cooler night is then on order for tonight behind the cold front. Some locations may be as much as 20 to 30 degrees cooler than last night.
High pressure east of the Bahamas continues to ridge west across the Florida peninsula. Another day of above average temps can be expected tomorrow before a cold front moves through the area late tomorrow bringing in some cooler temps and less humid conditions for the end of the week. High pressure ridging across the peninsula will produce southwest winds around 5-10 knots over the coastal waters tonight and early tomorrow morning.
559 PM EST Wed Mar 1 2017 It will be warm and windy ahead of a cold front this afternoon. Dry and cooler conditions will follow the front for the end of the week. Convection continues to push eastward along and ahead of a cold front with some discrete cell convection starting to blossom over northeast GA and Upstate SC recently. Drying will occur behind the cold front Thursday.
Cold front continues to march across the mid state this afternoon with a line of storms well ahead of the surface boundary about to exit Middle Tennessee. Drier air is already working its way in behind the front with considerably cooler air poised to advect into the region overnight.
High pressure continues to retreat east away from the U. this evening, with the western edge of the ridge between the Keys and Bahamas. As of 1030 pm, the radar started to detect the development of showers south of the Lower and Middle Keys. A cold front, located this evening over the southeast U.
A broad flat "dirty" ridge over the area is moving slowly east. There will also be patchy fog/freezing fog over the west side valleys later tonight. A trough will dig offshore tonight into Thursday. This will initially pump up the ridge over the area.
Drier airmass to continue to spread south across the region in wake of a cold front.
Fairly strong cold air advection will continue via northwest flow on Thursday, as an area of high pressure pushes toward the Tennessee Valley. This will make for a cooler day on Thursday, with highs in the lower to mid 50s. A stronger (but dry) cold front is still expected to push through the area on Thursday night. This should bring breezier conditions to the area, but mainly in the higher elevations.
910 PM EST Wed Mar 1 2017 The advance of a strong cold front has brought showers and thunderstorms to the Upper Ohio Region for today. Much cooler temperatures will then last through much of the weekend. Pressure rises as well as rapid cold advection behind this evening's cold front will work to continue to allow the column to be unstable, thus allowing for increased vertical mixing in the post-frontal environment. Strong low level lapse rates look to extend up toward the lower part of the dendritic growth zone simultaneously with the column supporting a changeover from rain to snow. Fries Cold advection within upper troughing should result in limited lake and terrain enhanced snow showers.
The cold front continues to push southeast towards the area. Our approaching cold front continues to push eastward, stretching from OH down to southwestern LA. National radar mosaic shows a narrow line of thunderstorms ahead of the cold front. The dynamics for this system are potent for neighbors to our north, but as the front approaches our local area, instability will be dropping quickly and the low level, mid and upper level jets will be lifting northeastward.
548 PM CST Wed Mar 1 2017 The synoptic pattern this afternoon features a strong PV anomaly digging into the southern Great Lakes, which has helped to carve out an upper-level trough over much of the Midwest into the northern Plains. While this trough will push further to the east tonight, yet another PV anomaly will help sharpen the trough over the Midwest by late Thursday. The gusty west-northwest winds we have experienced this afternoon will die down this afternoon as the boundary layer decouples and surface ridging briefly nudges into the region. Given the deep mixing, expected sunshine, and strong WSW winds ahead of the surface cold front dropping through, have raised highs above guidance over central and eastern MO.
459 PM MST Wed Mar 1 2017 Decided to expand the high wind warning through midnight to include SE Fremont & SW Natrona Counties (zone 19).
A sunny and breezy day had taken shape after a strong cold front moved through the region last night. Cooler temperatures were in place as winds were gusting in the 20 to 30mph range across the area. Winds will lighten up this evening as a lobe of high pressure slides over the Ozarks and temperatures fall into the 20s tonight. High pressure will be in control of the regions weather for the end of the week and into the weekend. A relatively flat upper level ridge will slide over the region which will help to bring a warming trend to the Ozarks through the weekend.
Minimum temperatures tonight will be warmer than last night with the continued warmer foothills and urban corridor due to some downsloping pressure gradient still existing. Temperatures will be slightly warmer but the northwesterly flow will keep them cooler than average.
628 PM EST Wed Mar 1 2017 MVFR conditions at KTRI will continue ahead of the cold front through 02z. The cold front will move through the terminals over the next hour or so with winds shifting around to the west.
544 PM CST Wed Mar 1 2017 Early afternoon surface analysis indicated ridge axis from central ND into western NEb. The surface reflection of this trough is low pressure over eastern MT and this will also track southeast through SD and into IA over the next 24 hours.
430 PM CST Wed Mar 1 2017 The synoptic pattern this afternoon features a strong PV anomaly digging into the southern Great Lakes, which has helped to carve out an upper-level trough over much of the Midwest into the northern Plains. While this trough will push further to the east tonight, yet another PV anomaly will help sharpen the trough over the Midwest by late Thursday.

535 PM CST Wed Mar 1 2017 A cold front currently extends from Cameron NE to Opelousas and is moving to the SE early this evening. VCSH and some TEMPO -RA will be possible for KLFT and KARA over the next 2-3 hours before the cold front moves through. /issued 240 PM CST Wed Mar 1 2017/ Wx map shows cold front moving through Central and Western Louisiana this afternoon. With temperatures in the lower to mid 80s and dewpoints in the upper 60s to lower 70s ahead of the line, a broken line of showers and thunderstorms developed within the last couple of hours along the frontal boundary.
Snow chances are highest in the highway 14 corridor and across much of southwest Minnesota late tonight and Thursday morning. A decent amount of forcing and moisture, expect highest amounts of up to 3 inches of snow in the Buffalo Ridge area.
Cooler air will arrive tonight. /issued 538 PM CST Wed Mar 1 2017/ The cold front has moved through the area and we will begin transition to a colder high pressure system for the next couple of days. As an upper level trough moves to the east.
816 PM EST Wed Mar 1 2017 A strong cold front will pass through the area tonight.
/issued 551 PM CST Wed Mar 1 2017/ For the 02/00Z TAFs, VFR conditions will dominate behind recently departed cold front. Otherwise, clouds will be limited to cirrus still lagging behind the cold front but SKC conditions are expected at all sites after 02/03Z. /issued 301 PM CST Wed Mar 1 2017/ The aforementioned cold front has finally moved through the entire region, leaving behind mostly sunny skies and gusty northwest winds near 20 mph with higher gusts. Its possible some overnight lows may fall to around the freezing mark north of the interstate 30 corridor over the next couple of nights.
A low pressure system over the ne pac will continue to spin disturbances into our area tonight and showers will persist into Saturday morning. The first strong Pacific low pressure system continues to move across Vancouver Island into the B. May also see some strong gusts Saturday evening as the second system's cold front moves across the basin.
Upper ridging will be over the region today with south to southwest winds.
