242 AM EDT Mon Aug 21 2017 High pressure into Tuesday. strong cold front late Tuesday/Tuesday night. Cooler and drier high pressure into the weekend.
122 AM EDT Mon Aug 21 2017 A weak pressure trough will linger in the forecast area through Monday. However, upper ridging over the region will help keep moisture shallow and limit the thunderstorm chances.
An upper level trough will track from south-central Canada across the Northern Plains and Upper Missippi Valley today into tonight. This wave will eject slowly northeastward into western Kansas today, ahead of the main upper level trough to the north. A moderately-strong southerly low-level jet will develop tonight, ahead of a southward moving cold front which is progged to move into central Kansas after midnight. The cold front will push southward through southern Kansas Tuesday, with a chance of lingering showers/thunderstorms, while clearing occurs in the northern part of the state.
627 AM EDT Mon Aug 21 2017 A weak pressure trough will linger in the forecast area through Tuesday. High pressure centered off the coast will cause increased moisture in a southeast to south flow. However, the moisture will remain shallow because of upper ridging and limit thunderstorm coverage.
610 AM EDT Mon Aug 21 2017 High pressure will build south of the area today. Low pressure will approach from the west on Tuesday.
Temperatures will be cooler east of the Divide, with the plains cooling to below seasonal norms. Readings should be in the low to mid 80s.
300 AM EDT Mon Aug 21 2017 A weak upper level trough will return slight rain chances to the forecast today. Widespread showers and thunderstorms are expected with the approach and passage of a cold front Tuesday and Tuesday night. Isolated thunderstorms are possible by late afternoon as the ridging flattens and convective temps are reached. By Tuesday, strong low pressure is forecast to track across the Great Lakes, pulling a cold front toward the Ohio Valley. Showers and thunderstorms are expected as the front approaches, and as a pre frontal trough tracks across the area.
To the west of this low, an axis of higher moisture (precipitable water values around 2") is currently located over the western Gulf of Mexico. On Tuesday, the above mentioned TUTT low will begin to weaken and slow it's westward progress as it encounters the subtropical ridge axis.
530 AM EDT Mon Aug 21 2017 High pressure moving off the Mid Atlantic coast will bring a warm and increasingly humid southerly flow to the region into Tuesday. A strong cold front will move through the region late Tuesday and Tuesday night. Cooler and drier conditions will return for the second half of the week. High pressure will slide off the coast and a warm and more humid airmass will return to the region. Convection will tend to decrease quickly after sunset with a warm and muggy night in store ahead of an approaching cold front.
540 AM EDT Mon Aug 21 2017 A weak upper level trough will return low rain chances to the forecast today. Widespread showers and thunderstorms are expected with the approach and passage of a cold front Tuesday and Tuesday night. Isolated thunderstorms are possible by late afternoon as the ridging flattens and convective temps are reached. By Tuesday, strong low pressure is forecast to track across the Great Lakes, pulling a cold front toward the Ohio Valley. Showers and thunderstorms are expected as the front approaches, and as a pre frontal trough tracks across the area.
SHORT TERM (Today through Tuesday):Water vapor satellite imagery shows the center of 500 mb low pressure spinning over the central Gulf of Mexico south of the Mississippi River delta and north of the Yucatan Peninsula. Deeper tropical moisture, combined with the 500 mb low weakening the long-standing 500 mb high pressure ridge, will result in isolated showers and thunderstorms for the immediate three coastal counties of the BRO CWFA as well as all Lower Texas coastal waters.
This is occurring as meso- ridge waves rotate around the low to mid level stacked high centered near the Carolinas.
257 AM PDT Mon Aug 21 2017 A weak low pressure system off the Southern California coast will keep high temperatures a few degrees below average today with areas of low clouds with patchy fog and drizzle extending into portions of the inland valleys this morning.
An approaching cold front and upper disturbances will interact with a very warm, moist and unstable atmosphere and result in unsettled weather over all or parts of central Indiana through Tuesday evening. These cells were triggered by the upper wave moving over the lower Great Lakes which was seen nicely in water vapor imagery. Cirrus and re-newed convection suggest temperatures may be a degree or two cooler than MOS and the blend and especially in between 2 and 3 pm, when temperatures could drop a couple of degrees, even if cloud cover is less than expected. Still, highs in the mid and upper 80s north to the lower 90s south look good.
441 AM CDT Mon Aug 21 2017 An upper low near the Four Corners region and southern Rockies this morning will track slowly east and northeast through tonight as it approaches the Panhandles. Convection is expected to increase today and tonight with subsidence behind the departing upper trough on Tuesday resulting in a decrease in convection by Tuesday morning. However, a second upper trough will approach the Panhandles from the central and southern Rockies by late Tuesday as an upper high builds near far West Texas and the southern Rockies and allows for the upper flow to transition to northwesterly. A cold front will push slowly through the forecast area Tuesday before stalling late Tuesday just east and south of the Panhandles.
At the surface, a cold front extended from James Bay through ern Upper Michigan to cntrl WI. Today, expect mid clouds to gradually increase as WAA strengthens ahead of a trough developing from Nebrasaka into WI. Tonight, as the mid level trough deepens into the n cntrl CONUS the models have trended toward a stronger sfc wave of low pressure lifting into se Upper Michigan late tonight. On Tuesday, we could see some lingering showers across the east as a cold front continues to push across Upper Michigan. Behind this system, high pressure will slide down from Canada and linger across the area on the western side of longwave troughing.
655 AM EDT Mon Aug 21 2017 High pressure moving off the Mid Atlantic coast will bring a warm and increasingly humid southerly flow to the region into Tuesday. A strong cold front will move through the region late Tuesday and Tuesday night. Cooler and drier conditions will return for the second half of the week. High pressure will slide off the coast and a warm and more humid airmass will return to the region. Convection will tend to decrease quickly after sunset with a warm and muggy night in store ahead of an approaching cold front.
2024 is the next total solar eclipse, and that one will cross over Texas! Next order of matter is a cold front on Tuesday.
343 AM EDT Mon Aug 21 2017 High pressure into Tuesday. strong cold front late Tuesday/Tuesday night. Cooler and drier high pressure into the weekend. With weak high pressure in control today and tonight, the biggest effect on our weather will be lowering maximum temperatures by 1 to 2 degrees due to the eclipse this afternoon. For tonight, high pressure does slide eastward, but still controls things with a tranquil and mild night. As the uppe level trough digs into the Great Lakes, there will be two actual cold front pushing through the Ohio Valley and the mountains.
An upper low moving west across the Gulf of Mexico is expected to enhance onshore flow once again today, which should result in more scattered convection this afternoon, especially east of a line from Lufkin to De Queen. Thunderstorm chances are still expected to be on the increase from north to south beginning late Tuesday as a cold front and upper trough axis dive southeast towards the area.
404 AM CDT Mon Aug 21 2017 Broad upper level trough was over the Northern Plains with short wave in the flow.
Lows will be in the low to mid 70s, with some patchy fog possible towards daybreak. Lows will be in the low to mid 70s with only a few patches of light fog around at daybreak. Tomorrow, the subtropical ridge aloft over the Lower MS Valley will start lessening its grip a bit, but certainly not in a dramatic way.
Latest IR satellite imagery shows mostly clear conditions across the region with a few patches of mid clouds from the Tahoe Basin through the highway 50 corridor. This increase in clouds is associated with the lead edge of moisture being drawn up from the south as an upper low approaches the region.
Aloft, an upper level ridge rules across the southeast CONUS, with flatter flow across the majority of the Mississippi Valley. A more vigorous short wave trough is moving southeast out of the southwest Canada, currently moving through the British Columbia/Alberta border. The next 24 hours will remain dry, as the upper level ridge to our southeast remains in control. Meanwhile, the Canadian short wave trough will deepen and continue to move southeast, reaching the Great Lakes region by dawn Tuesday. As the short wave trough continues to amplify across the U. /Canadian border on Tuesday, low pressure will organize and deepen rapidly along the surface boundary to the east. The cold front will move southeast across the Ohio Valley Tuesday afternoon, with showers and thunderstorms breaking out along and ahead of the boundary.
335 AM EDT Mon Aug 21 2017 Above normal temperatures will persist across the Ohio Valley through Monday ahead of a cold front. The cold front will bring showers and thunderstorms on Tuesday, then drier and cooler air moves in for the rest of the week. Tonight a potent upper level system over the Hudson Bay will begin to wrap up into an upper level low and head south. Also at this time the cold front has yet to enter our CWA. However, as the cold front pushes off to our southeast and drier air begins to filter in behind the front, expect pcpn to taper off from the northwest as we head into Tuesday night. This will lead to mainly dry and cooler conditions.
Otherwise, upper and surface ridging will produce VFR conditions and light and variable winds at all TAF sites.
643 AM EDT Mon Aug 21 2017 High pressure centered off the coast will cause increased moisture in a southeast to south flow. However, the moisture will remain shallow because of upper ridging and limit thunderstorm coverage.
131 AM EDT Mon Aug 21 2017 High pressure will bring clear skies and seasonal temperatures to the region tonight. A strong cold front will approach the region later on Tuesday, bringing a chance of stronger thunderstorms with it. Cooler and drier conditions will return for the second half of the week. Strong high pressure and subsidence providing a clear overnight. High pressure moves east with southerly and more warm and humid flow returning. Any convection will decrease quickly after sunset with a warm and muggy night as area in the warm sector ahead of cold front.
Ridging takes hold overnight into Sunday morning with plenty of clear air upstream. Southwest winds will gust to near 20 knots ahead of a low pressure system moving east through central WI. PC A weak wave of low pressure will track across central WI into Lower MI today. A surge of warm advection on the nose of a 35-40 kt wnwly LLJ will accompany the low this morning into the early afternoon. A cold front will likely come off Lake MI in the wake of the low for late today into the evening but should be relatively modest for this time of year. A mid level ridge will move over the region. High pressure moving across the upper Great Lakes will create an enhancement of the northeast winds. It will surge inland creating a surface boundary against southwest winds from approaching low pressure.
632 AM CDT Sat May 13 2017 Continued VFR with light southerly winds under an upper ridge.

Dry conditions expected today as the trough axis shifts east and drier air slowly moves in from the west. Morning clouds will greet the area on Sunday, as mid and upper level moisture moves southward on the back-edge of the exiting trough.
652 AM CDT Sat May 13 2017 High pressure moving across the region today will maintain VFR conditions. As the high moves off to the east tonight and tomorrow, the north to northeast winds will swing back around to the southeast.
The 7 am regional surface analysis showed a 1006 mb low approaching Columbus, GA, with a trailing "cold front" through Pensacola, FL and into the central Gulf of Mexico. Vapor imagery and upper air data showed a weakening, positive-tilt trough from north GA through southern MS. 500 mb winds along the southern flank of this trough (i. We expect the highest PoPs will be this morning, especially in south GA where the southern end of a relatively weak QLCS was moving quickly eastward.
1255 PM EDT Sat May 13 2017 Hydro Weak low pressure with move through today with only a slight chance of showers.
741 AM EDT Sat May 13 2017 Aviation Weak low pressure with move through today with only a slight chance of showers.
1155 AM EDT Sat May 13 2017 Low pressure and a trailing cold front track east across SC this afternoon. Weak high pressure will build over NC.
A weak weather disturbance will push a second cold front across northern and central Utah today.
1011 AM EDT Sat May 13 2017 Low pressure continues moving across the region and will move through the Midlands late this morning and offshore this evening. This will keep showers and thunderstorms over the area today with high pressure and drier air overtaking the region tonight.
536 AM MDT Sat May 13 2017 Mid/upper-level ridge axis has shifted east into the plains with southwest flow ensuing in its wake. At the surface, 994mb low pressure area was centered just east of Billings at 07Z, with a well-defined cold front extending south/southwest thru western WY. As a result, expect the aforementioned cold front to make very little progress towards the CWFA during much of the day. The late arrival of the cold front will be problematic when it comes to convection, likely delaying any development until early/mid afternoon ovr the Laramie Range and late afternoon/evening ovr E-central WY and the N Nebraska Panhandle. Temperatures will be a few degrees cooler Sunday behind Saturday nights weak fropa.
657 AM CDT Sat May 13 2017 A weak wave of low pressure will track across central WI into Lower MI today. A surge of warm advection on the nose of a 35-40 kt wnwly LLJ will accompany the low this morning into the early afternoon. A cold front will likely come off Lake MI in the wake of the low for late today into the evening but should be relatively modest for this time of year. A mid level ridge will move over the region. High pressure moving across the upper Great Lakes will create an enhancement of the northeast winds. It will surge inland creating a surface boundary against southwest winds from approaching low pressure.
The mid-level ridge axis will shift east of the forecast area this evening and will be replaced by a long fetch of SWly flow aloft moving in from the subtropical Pacific. Slightly warmer than normal temps are expected under abundant sunshine and light to moderate southerly winds Sunday.
1055 AM CDT Sat May 13 2017 High pressure over the southern plains should keep light northerly winds in place today with mostly clear skies. /ISSUED 652 AM CDT Sat May 13 2017/ High pressure moving across the region today will maintain VFR conditions. As the high moves off to the east tonight and tomorrow, the north to northeast winds will swing back around to the southeast.
Farther south it is a different story where stronger heating will occur pushing high temperatures into the low-mid 90s with near record highs especially at Vero Beach. Over these areas, better heating will produce hot temperatures in the low-mid 90s and RH values should fall slightly below 35 percent.
/issued 528 AM CDT Sat May 13 2017/ The low cloud deck extends over much of Louisiana and deep east Texas still this early morning, all moving S/SW in the low level flow around 20 mph. All in all it will be a nice day with high pressure of 1015mb over N Arkansas sinking southward into the Mississippi valley. The cooler NE winds will end soon with a warm up as Southerly winds return during Mother's Day from West to East.
A large closed upper level low pressure system continues to sit over the region. The center of the low is over Portland but sill slowly move eastward Washington late this afternoon and overnight.
An upper level trough axis continues to move eastward across eastern and southern AL, as well as the northwest FL Panhandle this morning, while a weak cold front meanwhile continues to push across south central AL and the northwest FL Panhandle. An upper trof over the southeast states (phased with an upper trof over the interior eastern states) moves off to the extreme northeast Gulf and western Atlantic through tonight.
Mid level ridge axis to shift over the forecast area today. On the surface, warm frontal boundary currently along the ND/SD border into west central Mn expected to lift north to near the highway 2 corridor by evening. North of the boundary cooler but still seeing highs in the 70s. Thermal ridge axis ahead of surface boundary reaches the western fa by tomorrow morning. Region shifts into mid level sw flow Sunday as upper ridge shifts east.
646 AM CDT Sat May 13 2017 After some isolated morning fog in a few areas, the sun will again dominate the region with high pressure in firm control. As the high moves off to the East, the pressure gradient will tighten up some allowing the winds to kick around to the South as the next short wave approaches the region.
601 AM CDT Sat May 13 2017 Amplified upper level ridge remains the dominant feature over the next few days as it slowly traverses eastward across the center of the country.
702 AM EDT Sat May 13 2017 A cold front will pass through from the west today. A weak and dry cold front will move through from the north Sunday night.
Temperatures today will be in the lower 80s across the region with light winds which makes this a great day for outdoor activities. /issued 528 AM CDT Sat May 13 2017/ The low cloud deck extends over much of Louisiana and deep east Texas still this early morning, all moving S/SW in the low level flow around 20 mph. All in all it will be a nice day with high pressure of 1015mb over N Arkansas sinking southward into the Mississippi valley. The cooler NE winds will end soon with a warm up as Southerly winds return during Mother's Day from West to East.
Low pressure centered over Mississippi with associated cold front stretching from the low south into the northern Gulf coast. This low pressure will gradually make its way into the Florida Panhandle shifting the low level flow more southerly overnight. Dewpoints in the upper 60s combined with max temperatures near 90 degrees will lead to heat indexes from the low to mid 90s. Mother's Day, both the GFS and ECMWF prog the cold front to press over southern Florida continuing the trend of higher pops over South Florida for most of the day.
927 AM EDT Sat May 13 2017 Low pressure over the southern Appalachians will deepen as it reaches the mid Atlantic Coast this evening and then move up the East Coast on Sunday. A weak cold front will drop across the lower Great Lakes tonight.
Warmest readings central and northeast this afternoon with highs a couple of degrees cooler in the south/southwest. GFS shows some weak Theta-E advection riding the ridge across western Iowa past 09z Sunday.
737 AM EDT Sat May 13 2017 Low pressure and its associated rainfall will track off the southeast and mid-Atlantic coast this evening, then deepen as it shifts north off the New England coast Sunday. The high-res models having a hard time, but the 10z HRRR showed some semblance of showers in the mountains. Some stratocu and cooler air aloft with upper energy over Northern VA may clip the Lynchburg to Buckingham area this afternoon with a few showers, but all in all anticipate increasing sunshine.
848 AM EDT Sat May 13 2017 Low pressure will track East across the region Today, with a cold front sliding through Tonight.
1049 AM EDT Sat May 13 2017 Data from the Key West morning radiosonde balloon indicated a very dry and stable air mass persisting through most of the lower troposphere. The higher levels had moistened and destabilized somewhat owing to the approach of a large-scale trough and associated forcing for ascent. Currently, air temperatures in most Keys island communities are rising slowly through the lower 80s, with dewpoint temperatures holding steady in the lower 70s. Significant wave heights will range from 1 to 3 feet, with the 3-feet seas most likely over the extreme southeastern Gulf of Mexico north of Dry Tortugas National park (the Pully Ridge buoy currently is reporting 2.
Main story today will be the low humidity values and increased winds.
Strong SW flow ahead of a cold front will keep the SCA and SCEC conditions in place across the coastal waters today.
542 AM MDT Sat May 13 2017 12Z TAF CYCLE Southwest winds aloft will strengthen today as an upper low moves into the PACNW. South to southwest breezes continue overnight across the higher terrain and eastern plains.
1037 AM EDT Sat May 13 2017 A cold front will push off the coast today. A weak and dry cold front will move through from the north Sunday night.
1059 AM CDT Sat May 13 2017 No significant changes to the forecast, but minor adjustments to the high temperatures and sky cover.
1033 AM EDT Sat May 13 2017 Low pressure will continue to move up the Atlantic seaboard through Sunday.
Maliawco With the cold front having now moved through most of the area, west, post-frontal winds are coming in stronger than forecast models showed. High pressure and clearing will arrive by Sunday morning as the upper low center will be cut into by a short wave ridge embedded within the otherwise SW flow aloft.
A mid level ridge will move over the region. High pressure moving across the upper Great Lakes will create an enhancement of the northeast winds. It will surge inland creating a surface boundary against southwest winds from approaching low pressure.
A broad high pressure area will build eastward, out of the Mississippi Valley, during the forecast period.
Once the low cigs lift/break up, VFR conditions expected for the remainder of the period all sites.
1033 AM EDT Sat Mar 24 2018 High pressure is centered over Central Florida and supports moderate northeast to east breezes across the Florida Keys. This high should slide southeast today, turning breezes to south of east. The forecast is on track and calls for no rain chances and a warmer afternoon. From synopsis, an area of high pressure centered over North Florida will slide east and then southeastward into the western North Atlantic this afternoon and tonight.
a wet snow heavy at times with some thunder-snow this morning to near the highway 34 corridor.
Short wave ridging aloft today moves east on Sunday and is replaced by southwest flow aloft over the region. This southwest flow aloft will bring a series of disturbances across the central high plains region ahead of the trough deepening into the far southwest U.
This weather system and associated cold front will intensify and move through all of northwest and west central Montana from mid morning through the afternoon hours where widespread precipitation will occur. Given road surface temperatures will be above freezing any snow accumulations that may occur will be on the grassy surfaces.
