219 PM CDT Sun Oct 23 2016 High pressure ridge over northern gulf will dominate wx pattern next few days, with above normal temps in the daytime. Cirrus will affect overnight lows which will be svrl degrees warmer than those of last night. Upper ridge to remain established into next wknd with continued dry and fairly persistent temps thru that time frame.
1117 AM MDT Sun Oct 23 2016 Upper ridging will strengthen today across the nrn Plains into the Canadian Plains. SErly winds today will continue into Monday with highs reaching the low 60s to mid 70s Mon aftn. Dry weather and slightly warmer than average temperatures will continue from Monday through the rest of the week as a mean upper ridge persists over the region.
A weak cold front is tracking southeast across the forecast area this morning while we are still under the influence of a upper level ridge. The frontal passage is dry and it will be only slightly cooler behind the front today. Temperatures for today are pretty close to the superblend guidance, but did go slightly cooler than superblend with the lows tonight in many spots, especially our northwestern cold air drainage locations.
The attendant cool air advection will cause temperatures to be 5-10 degrees cooler than yesterday, with highs in the lower 50s to lower 60s anticipated.
303 PM EDT Sun Oct 23 2016 High pressure, at the surface and upper levels, will continue to control the weather pattern for the first half of the week.
116 PM EDT Sun Oct 23 2016 Dry weather is expected today under high pressure. A crossing cold front will return shower chances to the area tonight, especially north of Interstate 80, before mainly dry and cool weather returns for the first half of the week. The stratocu should continue to decrease through the afternoon under ridging. The cold front is progged for an overnight passage. A crossing low level jet should also result in some gusty winds overnight in the ridges. Cool northwest flow will re-establish in the wake of the clipper and associated cold front. Can't completely rule out lake-enhanced showers across the north Monday, as the cooler air moves over the relatively warm Lake Erie waters.
There were some colder areas with patchy frost, including a couple of spots that touched freezing on the Plateau. An axis of high pressure was located over our eastern counties early this morning, and allowed maximum cooling. Since then, the ridge axis has moved to east TN. The southwest wind with sunny skies will help warm temps into the low to mid 70s today. This means we'll start to pick up some return flow and warmer temperatures today. Cirrus will also increase tonight into tomorrow ahead of a cold front which will switch winds to northwest at airports Monday morning.
Hi-res models keep the higher moisture profiles in the lower levels across northern/northeast SD into west central MN into the afternoon hours. Will continue to see cold air advection through the day as a subtle reinforcing shot of cooler air works into the CWA later today. Accompanying the cooler air during the day today will be stratus currently across much of northern and central ND.
Upper level high pressure otherwise will build in, with dry conditions tonight and Monday. Went closer to warmer GFS MOS low temperatures in the lower 60s tonight with low cloud development. It will be slightly warmer Monday as stratus breaks up midday. High in the lower to mid 80s expected.
A minor upper level trough was rounding the upper level ridge axis across the southern plains. The upper trough was moving into western MN and will dig and amplify as it moves into New England Tonight. The upper level ridge axis will amplify across the plains tonight as a more amplified upper trough moves onshore across the western US late Tonight. The front will come through dry as the broad upper ridge will continue across the southern and central plains. Highs should warm into the mid 70s across the southern half of the CWA and will be a bit cooler across the northern counties with highs in the lower 70s. Lows will be a bit cooler but still remain above seasonal norms, with lower to mid 40s.
A potent upper cyclone continues to spin over northeastern Canada with broad northwest flow from the Great Lakes and New England into the southeast states. Weak upper ridging extends along the northern Gulf Coast into the Southern Plains and Southern Rockies. At the surface, a weak trough extends from the Great Lakes southward across the Central Plains, with cool dry high pressure settling in across the southeastern CONUS. For the rest of today, pleasant weather conditions will continue as high pressure slowly settles in across the northern Gulf Coast and southeastern states. Expect colder temperatures in the low lying areas and along the Nature Coast. Temperatures will rebound quickly into the afternoon with highs perhaps a degree or two warmer than today, nearing 80 degrees over all of west central and southwest Florida.
343 PM CST Wed Jan 4 2017 (Tonight and Thursday) Mostly sunny and cool across West Central Texas this afternoon, with temperatures ranging from the lower 40s across the I-20 corridor at Sweetwater and Abilene to the low 50s across the I-10 corridor from Ozona to Sonora and Junction. Temperatures will struggle to climb above the freezing mark across the Big Country, with readings farther south climbing ahead of the front and then becoming colder by afternoon.
Satellite showing upper low center located over southwestern Oregon this morning with snow extending over most of southern and central Oregon. The low will continue to slowly move east today.
200 PM MST Wed Jan 4 2017 Light snow probabilities will increase along and north of the interstate this evening as moisture in the 850-500mb layer increases ahead of an approaching upper level trough.

Brisk nw winds of 15-25 mph between 1031 mb arctic high pressure over eastern Nebraska and 986 mb low pressure over southeast Canada. Arctic high pressure will continue to build into central and southeast Illinois today. Upper-level troffing continues to dig across the northern Plains, upper Midwest, and Great Lakes region through the period. A weak impulse/110 kt 300 MB jet streak will round the base of this digging trof passing through the forecast area later tonight into Thursday. Area of light snow will quickly streak southeast Thursday morning, with the highest chances south of I-70. Much of the latter part of the week into the weekend will be quiet, as high pressure drifts across the area.
257 PM EST Wed Jan 4 2017 High pressure will continue to build from west of the area this afternoon into tonight.
High pressure aloft will settle into the region by the first half of the weekend. A mild and moist westerly flow extends inland across the Great Basin this morning, while an upper low remains situated along the Pacific northwest coast. A surface boundary remains stalled roughly along I-80 this morning, with valley locations south of this boundary having mixed out and warmed into the upper 30s to low 40s, while north of the boundary temperatures remain near or below freezing. This boundary is expected to remain roughly stationary through the afternoon before pushing south this evening, as the upstream upper low moves inland and into the northern Great Basin.
Drier air pushed out the last of the low level clouds a few hours ago as high pressure nosed it's way southward into the region.
Not confident that ceilings will lower Thursday afternoon at this time, with dry air in the low levels lingering. Some freezing spray will linger for a time this afternoon toward the open waters. We remain in the zone between an arctic ridge stretched from the northern plains to Illinois and low pressure slowly pulling away to the northeast.
314 PM CST Wed Jan 4 2017 Shallow dome of cold and dry Arctic Air firmly in place across eastern OK and western AR this afternoon with temperatures struggling to warm much above freezing in some areas despite near full afternoon sun. however some increase in low level moisture possible across southeast areas by early Thursday morning and will need to watch this area for any patchy drizzle or freezing drizzle.
Meanwhile an elongated trough axis was stretched just off the Oregon coastline through Oregon into Idaho. In response at the sfc, a few areas of low pressure have developed across the northern CO and UT areas.
High pressure in the Central Plains will nose east into the region and help keep the arctic airmass in place through the weekend. A cold front has moved over the Appalachians and into the mid Atlantic states this morning. With cold advection, temperatures will struggle to rise much during the day today, with high temperatures ranging from the mid to upper 20s across the upper Miami Valley to the lower 30s into northern Kentucky.
128 PM PST Wed Jan 4 2017 Rain will spread across the region from north to south today and tonight as a cold front approaches.
At the surface, winds were from the north to northeast behind a cold front. The frontal boundary will come back through as a warm front tonight. Another cold front will drop through our CWA Thursday.
Radar continues to indicate widespread snow across the forecast area, with the low wrapping up over western Oregon. Upper level trough is moving onto the southern Oregon coast this morning. A broad swath of light to moderate snow has moved over the area and is expected to continue throughout the day as a warm front remains stalled along the Nevada border. The trough will begin to weaken this afternoon as it starts to move inland off the Oregon coast and tracks over southeast Oregon and southern Idaho this evening.
1237 PM EST Wed Jan 4 2017 A dry cold front will cross the area today allowing colder and drier air into the region. Moisture will begin returning to the area Thursday as low pressure begins developing in the far western Gulf of Mexico.
235 PM MST Wed Jan 4 2017 Upper air analysis shows upper low across the Great Lakes region with a trough extending westward toward ND/MT. Surface analysis shows arctic high pressure building into the northern plains. Skies will clear out Thursday as the center of the high crosses the region. Slightly warmer air will begin working back into the area Thursday night.
/issued 433 AM CST Wed Jan 4 2017/ The cold front that ushered in cooler air last night has moved through the region this morning, leaving low clouds across most of the region. Predawn temperatures have fallen into the 30s across our northwest zones as cold air advection remains very strong in the wake of the cold front even with cloud cover and strong post frontal winds.
301 PM CST Wed Jan 4 2017 High pressure has been the dominant weather feature of note today, but things change as we head towards the end of the week.
342 PM CST Wed Jan 4 2017 A surface trof of low pressure was located over western Lake Superior at 20Z. Meanwhile, high pressure was over the Dakotas. A northerly flow aloft was found over the forecast area being pulled down from northern Canada as a closed low departs. As the high moves closer, expect the wind to diminish after sunset. That results in warmer wind chill values than previous forecast. The aforementioned surface trof will stay over western Lake Superior through Thursday.
300 PM CST Wed Jan 4 2017 1040 mb Arctic high pressure over British Columbia Canada and ridging southeast into the MO valley will continue below normal temperatures across central and southeast IL the next several days. Lows tonight in the low to mid teens, with upper teens by highway 50. The snow should be pushing off to our east Thursday night as high pressure starts to build east into central Illinois.
A weak short wave trough embedded in the flow moves across the forecast area early Thursday.
Also light precip may develop over northern with flurries, while in the southwest light rain or light freezing drizzle or sleet.

Expect periods of sun and warmer temperatures today.
257 PM EST Wed Jan 4 2017 A cold front moving through the region will bring blustery west winds and noticeably colder temperatures for the rest of the week. The weather will remain unsettled into the weekend with seasonal but below normal temperatures and continued chances for snow mainly over the higher terrain. Bufkit model soundings indicate we'll be well mixed through the low levels, able to tap into the westerly low level jet of around 50 knots.
Arctic high pressure will continue to build into the region this morning while cold air and northwest winds combine to create bitterly cold wind chills across the area. The center of the high is to the west over eastern MT. northwest winds will continue as the high remains to the west. The main upper trough will move through the area tonight. clouds will likely decrease across the area and warmer air will begin to move into the area aloft.
258 PM EST Wed Jan 4 2017 Latest surface analysis and IR satellite imagery show weak cold front currently across south central Florida this afternoon with abundant cloud cover across S Florida. The higher instability is more noticeable along the eastern portion of S Florida and the Atlantic waters. Front begins to exit the area into Florida Straits quickly tonight bringing cooler and dry air into the region under northwest flow. Expect cooler temps tonight ranging from mid to low 50s interior and mid to low 60s along the east coast metro.
The cooler airmass behind the front that pushed through yesterday has already begun to erode away. Cooler air is still holding on across the NE Permian Basin where temperatures are in the 40's. The front will make it to central portions of the area just after sunrise Thursday before hanging up across the higher terrain during the afternoon. Look for a wide range of temperatures Thursday afternoon with the Rio Grande seeing highs near 80 and Snyder possibly not making it much above freezing.
High pressure continues to strengthen across the Northern Rockies, inducing widespread clearing for all but Lemhi County, Idaho this afternoon.
222 PM EST Wed Jan 4 2017 Low pressure will continue to lift north of the region tonight.
But solutions are on track with a sharp cold front arriving out of the Texas Panhandle during the early morning hours on Thursday. Afternoon temperatures for the most part will be sub-freezing.
This will allow temperatures to drop into the low to mid 20s over much of the region due to the good radiational cooling.
with weakened surface winds as the region falls just downstream of an approaching cold front. /ISSUED 955 AM CST Wed Jan 4 2017/ The cold front that pushed through last night has cleared the coast, as indicated on visible imagery. Therefore, lowered both the high and low temperatures a tad. Lows temperatures tonight should be in the low 40s near College Station, and in the low-mid 50s along the Gulf. Forecast soundings are continuing to show saturation filtering back into the lower levels of the atmosphere this evening. A stronger cold front will push off the coast Thursday evening.
Forecast time-height sections/soundings indicate the low clouds should linger although ceilings are expected to rise a little with slow warming. /issued 245 AM CST Wed Jan 4 2017/ Weather map shows cold front now across the Gulf just south of the 60nm coastal waters boundary.
A dry cold front near the coast this morning will continue to push southeastward and over the Gulf. cool trough will remain anchored over the region allowing mid and high level cloud cover to continue to stream across the north central Gulf region. Today's high temperatures will be considerably cooler than what we've experience the past few days. Tonight's lows should fall into the low to mid 30s and upper 30s to low 40s near the coast.
222 PM CST Wed Jan 4 2017 Upper level analysis and water vapor channel satellite imagery depicts a closed mid-upper level low moving inland from the Oregon coast early this afternoon.
109 PM CST Wed Jan 4 2017 Udated the forecast to lower the high temperatures for today and made adjustments to the rain chances for early Thursday and into the afternoon. Cloud cover today will keep temperatures slightly cooler today and lowered the forecast highs. /issued 433 AM CST Wed Jan 4 2017/ The cold front that ushered in cooler air last night has moved through the region this morning, leaving low clouds across most of the region. Predawn temperatures have fallen into the 30s across our northwest zones as cold air advection remains very strong in the wake of the cold front even with cloud cover and strong post frontal winds.
326 PM EST Wed Jan 4 2017 The tightly packed pressure gradient, from a low pressure system currently over Quebec, has resulted in gusty winds today. These winds will slowly slacken this evening and tonight as the low continues to track off to the northeast and away from the region. For the remainder of the evening into the overnight hours, weak surface ridging will build in bringing drier conditions before another chance for snow showers re-enters the picture on Thursday. An area of vorticity and longwave troughing will push across the region tomorrow. This troughing coupled with westerly winds is expected to bring another chance for more snow showers during the day tomorrow.
/Issued 1011 AM CST Wed Jan 4 2017/ Cold high pressure firmly situated over the region today.
MVFR cigs are expected through the afternoon ahead of a cold front. Expect variable cloudiness during the day as the trough and front move through, but no precipitation is expected. Temperatures this afternoon will range from around 60 in the north to the lower 70s in the southeastern Big Bend.
Some additional MVFR/IFR cigs and vsbys from some low clouds and patchy fog may redevelop after 06Z tonight ahead of a secondary cold front working its way south through the region, otherwise VFR will continue.
Cold front on track for between about 08z and 12z Wednesday morning. RMcQueen Potentially will be updating for warmer highs today across at least the western south plains and extreme southwest Texas panhandle; short range solutions trending warmer. A dry cold front is expected to arrive near 12Z Thursday morning.
208 PM CST Wed Jan 4 2017 Strong cold front will push through tonight.
High pressure will build into the area, reinforcing Arctic air through the weekend. Forecast lows at the warmer end of guidance. Road model shows that road temperatures will be below freezing at the start of the day but be able to warm above freezing from mid morning through much of the afternoon. However, road model shows pavement falling below freezing again in the late afternoon/early evening.
A cooler and drier airmass will filter in through the night, with the low/mid clouds diminishing this evening. The high clouds may stick around a bit longer.
The winds will shift towards the east and southeast today but back towards the northeast tonight as a cold front moves across the area. Another surge of cold air is expected to move into the region later tonight into Thursday morning as upper trough swings across the Northern/Central Plains into the Great Lakes area.
1011 AM CST Wed Jan 4 2017 Cold high pressure firmly situated over the region today.
Surface wise, a trough of low pressure is draped from south central Florida into the extreme southeast Gulf of Mexico. The aforementioned trough will migrate through our entire area this evening, with a weak pressure pattern along with drier air to follow late tonight and continue through the balance of this week.
Expect slow improvement late in the morning from south to north as the warm front moves further north. Today Through Tuesday Night An upper ridge will be over the central part of the U. An upper trough will then move through the state Tuesday. Rain chances will continue across central sections but will move north as a warm front moves in from the south. A cold front will then approach north Arkansas Tuesday night. This will bring in some cooler air. warmer temperatures are anticipated for today and Tuesday.
The ongoing winter weather advisory for the north is the highlight in the short term period.
623 AM EST Mon Feb 6 2017 Rain chances will be increasing late today through this evening as a low pressure system approaches from the Central Plains.
523 AM EST Mon Feb 6 2017 Warmer temperature can be expected today and rain tonight as low pressure moves toward the Great Lakes. Rain is progged to develop this evening as low pressure digs out of the Plains and across the Great Lakes.
Current temperatures are in the low to middle 50s. Most of the region will see morning lows in the low 50s. Rain is surging back to the North in response to a trough deepening over the Southern Plains. bringing warmer moister air across the Midsouth.
Breezy to windy conditions are then anticipated to develop by this afternoon as the low level pressure gradient tightens in response to a deepening sfc trof of low pressure over ern CO and ern NM, which will slide eastward today.
Abundant moisture was spreading over the western US ahead of a short wave trough entering the Pac NW. At the sfc, a stationary frontal boundary extends acrs northern LA into northeast TX, separating warm and moist air acrs the area (where temperatures are in the upper 60s) from a cooler airmass to the north (with temps in the 50s). Patchy fog and low clouds are seen acrs southern portions of LA, with dense fog developing on the coast near Cameron and over the nearshore waters as the warmer air spreads north acrs relatively cooler shelf waters. A mostly zonal flow will prevail aloft through midweek while warm and moist onshore flow continues in the lower levels.
639 AM EST Mon Feb 6 2017 Low pressure traveling from the Mississippi Valley to the Great Lakes will bring widespread showers and possibly thunderstorms tonight through Tuesday.
A lee trough will develop from western Kansas into the Texas Panhandle, resulting in an increased surface pressure gradient across West Central Texas.
808 AM EST Mon Feb 6 2017 High pressure will bring dry weather and mild temperatures today.
Fairly tricky forecast setting up in the short term as we will have to time frontal passage as well as the onset of colder air and and freezing drizzle or light snow. Attention will then turn to the evening and overnight hours as light snow and freezing drizzle become more of a possibility. Soundings are somewhat supportive of freezing drizzle and there could even be some very light icing in spots. Overall, any light snow or freezing drizzle accums look to stay on the light side overnight into Tuesday morning, before precip moves out of the area by Tuesday afternoon.
645 AM EST Mon Feb 6 2017 Aviation A low pressure system will track eastward from Wyoming through Michigan today and into Tuesday. A period of freezing rain will be possible across interior and northern parts of Lower Michigan for the Tuesday Morning commute.
Strength of the low level jet inhibiting fog formation with patchy fog mainly along the coast with MVFR vsbys. Temperatures will be slightly warmer than yesterday with breezy conditions expected this afternoon and early evening over the southern Coastal Bend. Low level jet will develop again this evening but shift to the east overnight as trough axis moves toward the Brush Country. The trough axis will move into the Coastal Bend with low level flow east of the trough axis becoming south-southwest Tuesday. Expect cooler water temperatures will keep wind speeds down slightly for the bays and near shore waters north of Port Aransas.
Today will likely see temperatures climbing into the low 70s with several areas seeing highs nearing the mid-70s. Low-level moisture will continue to stream into the region ahead of the trough, but a warm, dry layer above the moist boundary layer will provide an effective cap through the afternoon. Cap begins to erode by 03Z as cooler mid-levels air moves in.
