153 AM EDT Sat May 7 2022 A trailing cold front will move east across the Carolinas tonight. The low pressure and a reinforcing cold front from the north will then wobble from central VA southeast across eastern NC and offshore through Saturday. The warm front and rotating storms have shifted well to our NE. The main cold front is still over central NC with some weak convection.
1212 AM EDT Sat May 7 2022 Rain and cooler temperature expected through Saturday evening with the slow passage of a low pressure system. Low pressure will continue its slow advancement across the Ohio Valley region tonight.
355 AM CDT Sat May 7 2022 H5 analysis from earlier this evening had low pressure over Indiana. A trough extended south of this feature into Alabama and Georgia. West of this feature a positive tilted ridge extended from northeastern Nebraska into central Ontario. West of the ridge, a broad trough of low pressure was present across southwestern Canada into the northwestern CONUS. At the surface, a trough of low pressure extended from eastern Montana, south to eastern Wyoming. East of the trough, southerly winds will increase today. Highs will reach the lower to middle 80s, west of highway 83 and the combination of temperatures and dew points in the 50s, will lead to a corridor of 1500-2500 J/KG SB CAPE's east of highway 61 and west of highway 83.
410 AM EDT Sat May 7 2022 Low pressure over West Virginia this morning will move southeast today. High pressure will then build in leading to a prolonged period of dry weather. Showers rotating around low pressure located in West Virginia continue to move across the eastern part of the forecast area. As the low pushes southeast, precipitation will diminish through the morning. Northerly winds will be breezy across much of the area today, High pressure will start to build in through the period.
302 AM EDT Sat May 7 2022 Discussion/Marine - Fair wx this weekend - A ridge of high pressure will bring fair wx through the weekend. Skies will clear today in subsidence under the ridge and as a drier airmass continues to advect in. High temps today will reach the low to mid 60's.
431 AM EDT Sat May 7 2022 Weak ridging extending from eastern Cuba into the southwestern Gulf of Mexico has begun to weaken and lose its grip across the island chain and surrounding waters.
151 AM EDT Sat May 7 2022 A large ridge of high pressure will dominate our weather for the 7 days. Slightly cooler temps anticipated on Sat night, with lighter winds and clearer skies, wl support lows in the l/m 20s to l/m 30s most locations, with some frost likely.
This should help temps warm into the lower 70s, finally back to normal or slightly above for the first time this month.
With the cold front now through the region, a dry and mostly clear day is on tap for the area. This is due to low PW values less than an inch, and dry air advection into the region across the low and mid levels. Overall, temperatures will remain cool once again, with highs forecast to climb into the low to mid 80s areawide. Lows tonight will be cooler, with upper 50s across SE Alabama and SW Georgia, and low 60s across the Florida Panhandle and Big Bend.
Some light fog may develop early this morning over the northwest fringe of the forecast area, where winds have gone calm along the ridge axis.
302 AM CDT Sat May 7 2022 Cloud cover and light rain continue as the upper low continues to impact the eastern CONUS. The low will slowly progress eastward today, with light rain/drizzle possible through the day especially in the east.
Light showers or light rain continues across much of the region as disturbances move around the upper level low and the low level flow has an upslope west to northwest component. Stratus has built down to the ridgetops leading to reduced visibilities from fog in some areas as well. Further west, an upper level ridge was centered over Mexico and extended into the Southern Rockies and southern to western Great Lakes. The upper level low is expected to work to the mid Atlantic coast this evening and then meander near to just off the coast tonight and into tomorrow.
Lingering showers under an upper low on today, with cooler temperatures. Discussion: In the upper levels, a trough will be over the Mid-Atlantic and Southeast today. A ridge will build into the Mississippi Valley tonight. At the surface, low pressure will be near the North Carolina Coast today, moving offshore tonight as high pressure builds into the Ohio Valley and the Southeast. Showers will be off and on today for most of the region as wrap around moisture behind the low lingers. The best chance for rain will be in SW Virginia and the higher elevations of the mountains due to terrain forcing with perpendicular northwesterly flow. The higher elevations may see showers through around midnight.
The jet streak within the upper level trough should stregthen in the upstream region, helping progress the trough to the SE during the day. Elsewhere, highs will remain in the low to mid 60s, with a few far eastern locations barely reaching 60. Much more mundane weather is expected to end the short term, as high pressure builds beneath a developing ridge over the Midwest. With a delay in WAA over the region, these clearing skies will push temperatures near the dew point overnight, leading to lows in the low 40s.
Low had cold front into ID and trough into eastern WY. Low will drag a cold front through the CWA this afternoon/evening. 1KJ/kg MLCAPE will develop along cold front with modest MLCIN. 0-6km bulk shear around 50kts will support isolated strong/severe storms during peak heating when cap should break along cold front.
We will be located on the back side of the system and a ridge building across the Plains. Regardless, the greatest coverage of sky cover will remain north of the TN River and the cloud cover combined with the NW flow CAA will provide cooler daytime highs in the mid/upper 60s which is ~10 degrees below normal. As the Mid Atlantic system keeps pushing eastward, the dense cloud cover will start to move out and the ridge currently stretched across the Plains will filter in drier air to help erode additional cloud cover and will finally slack the winds.
Lows will be on the cool side, with readings in the lower 40s northeast and mid 40s elsewhere.
Weak impulses on the back side of the upper low over ern KY will continue to provide scattered light rain showers across the mid state overnight. Not too much cooler advection expected overnight. Clouds and patchy showers/drizzle will continue to spin around an upper level low and impact our terminals through the night and into Saturday morning.

Expect these conditions to continue through the morning hours as ample low level moisture coincident with a broad 850mb thermal trough slowly advects eastward. Continued cloudiness and a NW wind will quell diurnal gains in temperatures today, with afternoon highs peaking in the upper 50s to low 60s east of I-65 and into the low to mid 60s to the west. May also feel a few gusts in the 20-25mph range this afternoon as the pressure gradient remains tight between the departing low and building high pressure to the west.
454 AM EDT Sat May 7 2022 Low pressure was centered along the Virginia coast will drift southeast today and tonight with scattered showers and isolated thunderstorms over the region.
955 PM MDT Fri May 6 2022 The deepening trough continues to draw southward along the Pacific Coast today, and is starting to turn our flow more from the southwest. The leading edge of the trough will move east, bringing a jet streak across western WY by 12Z Saturday. The trough will also bring midlevel instability to the NW corner of the state. The trough will also bring a cold front across the state during the afternoon, focusing some of the winds, and bringing the rain chances east across the divide into central WY.
A cloud deck is pushing into the MO Bootheel and West TN this morning as another piece of upper level energy rotates around the upper low over the upper OH Valley. By late this afternoon high pressure at the surface and aloft build in and sunshine will increase east of the MS River.
1121 PM EDT Fri May 6 2022 Low pressure was over the Mid Mississippi and Tennessee Valleys this afternoon with a front extending from the low into the Carolinas.
Cool northeast flow lingers at the surface associated with our exiting low pressure system, which is currently centered over WV. Aloft we have a rapidly amplifying ridge entering in from the west, which will eventually lead to subsidence and decreasing clouds through the day. The upper ridge building into today will linger all the way through next Friday, and will preclude much if any precipitation through the period.
327 AM EDT Sat May 7 2022 Our region will be in between high pressure across eastern Canada and low pressure along the Virgina coast through tonight.
Showers and a chance of thunderstorms will accompany a cold front as it crosses through Oregon early tonight and into southwest Idaho after midnight. Isolated showers this evening increasing in coverage late tonight/early Saturday with cold frontal passage. Surface winds: SE-SW 15- 25kt, shifting to the NW 10-20kt behind cold front.
256 AM CDT Sat May 7 2022 Upper ridging will build in from the west will promote mostly dry conditions and warming temperatures throughout the weekend. A large upper trough over the western CONUS should shove the main ridge axis just to east of the CWA putting most of the area under southwest flow.
401 AM EDT Sat May 7 2022 Moisture will wrap around the backside of the low pressure system that will move over the mid-Atlantic today.
East winds will dominate and keep areas near Lake Michigan cooler. Low pressure over the Ohio Valley / mid Atlantic region will slide to the east as a ridge of high pressure pushes into Wisconsin.
405 AM EDT Sat May 7 2022 Showers have concluded along the MI/OH border early this morning as a Ohio Valley closed low migrates toward the Mid-Atlantic. Weakening dynamics expected aloft today as a pattern shift gets underway locally ahead of an inbound ridge axis. Aggressive system-relative isentropic downglide appears most pronounced within the mid-levels from an eastern Canadian anticyclone. Coastal communities likely even cooler given onshore flow off the relatively chilly Lake Huron waters. AVA increases overnight as the Great Lakes become encompassed by a latitudinally expansive ridge axis extending from the Gulf Coast to Hudson Bay.
309 AM EDT Sat May 7 2022 A cold front will sink slowly south across west central and southwest Florida through the day.
420 AM EDT Sat May 7 2022 Patchy light rain will end across the Southern Tier this morning as low pressure slowly moves off the Mid Atlantic coast.
1011 PM CDT Fri May 6 2022 Isolated to scattered light to moderate showers will continue as the back edge of a departing area of low pressure moves further away from our area.
1255 AM CDT Sat May 7 2022 Dry weather continues Saturday morning as upper level ridging remains over region.
1120 PM EDT Fri May 6 2022 A trailing cold front will move east across the Carolinas tonight. The low pressure and a reinforcing cold front from the north will then wobble from central VA southeast across eastern NC and offshore through Saturday. The warm front and rotating storms have shifted well to our NE. The main cold front is still over central NC with some weak convection.
103 AM CDT Sat May 7 2022 For the 07/06Z TAF update, a slow-moving warm front will continue to meander across our airspace, instigating MVFR low clouds and -RA over Deep East Texas airspace by 07/09Z-12Z. And only from daybreak into the mid morning hours along our weak returning warm front tail.
510 AM EDT Sat May 7 2022 Low pressure was centered along the Virginia coast and will drift southeast today and tonight with scattered showers and isolated thunderstorms over the region. High pressure, along with cooler and drier weather build in for Sunday.
Clear skies on Sunday with highs in the 80s as high pressure builds into the region.
848 AM EDT Sat May 7 2022 Low pressure was centered along the Virginia coast and will drift southeast today and tonight with scattered showers and isolated thunderstorms over the region. High pressure, along with cooler and drier weather build in for Sunday.
We will be located on the back side of the system and a ridge building across the Plains. Regardless, the greatest coverage of sky cover will remain north of the TN River and the cloud cover combined with the NW flow CAA will provide cooler daytime highs in the mid/upper 60s which is ~10 degrees below normal. As the Mid Atlantic system keeps pushing eastward, the dense cloud cover will start to move out and the ridge currently stretched across the Plains will filter in drier air to help erode additional cloud cover and will finally slack the winds. The ridge will continue to build and the height rises combined with the plentiful sunshine will help daytime highs rebound up into the mid/upper 70s on Sunday.
SCA conditions will continue across the waters through this evening as the front stalls and high pressure builds behind it.
Short wave ridge axis will reside over the area today, with the low level thermal ridge continuing to strengthen.
A cloud deck is pushing into the MO Bootheel and West TN this morning as another piece of upper level energy rotates around the upper low over the upper OH Valley. By late this afternoon high pressure at the surface and aloft build in and sunshine will increase east of the MS River. Upper ridging begins to strengthen over the region and surface winds become southeasterly. Upper ridging will dominate as an omega block forms over the CONUS.
Cloud cover is expected to slightly increase from the southwest as a building high pressure restores some southerly flow, which will increase moisture. Lows will dip into the lower 50s to low 60s.
639 AM CDT Sat May 7 2022 Upper ridging will build in from the west will promote mostly dry conditions and warming temperatures throughout the weekend. A large upper trough over the western CONUS should shove the main ridge axis just to east of the CWA putting most of the area under southwest flow. Warmer temperatures aloft should keep areas south of I-70 from seeing storms late tonight/early Sunday morning. The upper ridge will essentially stall over the central CONUS as it gets sandwiched between the upper low over the western Atlantic and the upper trough over the Rockies. This will promote much warmer temperatures to reside across the region going into the beginning of the week.
With the cold front now through the region, a dry and mostly clear day is on tap for the area. This is due to low PW values less than an inch, and dry air advection into the region across the low and mid levels.
246 AM MST Sat May 7 2022 Strong high pressure over the region will persist today matching temperatures seen yesterday with highs around 100 degrees across the lower deserts.
554 AM EDT Sat May 7 2022 It will be noticeably cooler and less humid today with a chance of showers and perhaps a rumble of thunder in the Northeastern Midlands.
Highs today will be in the low 80s for our northern counties, and mid to upper 80s for points south. Lows tonight are expected to range from the low and mid 50s over inland areas to the lower 60s closer to and along the coast.
844 AM CDT Sat May 7 2022 The base of an upper level trough lies across the Southeast this morning. At the surface, the cold front that impacted the area yesterday has now moved off the East Coast with a low centered over the Mid Atlantic. Across the Tennessee Valley, CAA on the backside of the trough axis has resulted in a surface inversion with a stratus deck formed at the top of it. As the Mid Atlantic system keeps pushing eastward, the dense cloud cover will start to move out and the ridge currently stretched across the Plains will filter in drier air to help erode additional cloud cover and will finally slack the winds. The ridge will continue to build and the height rises combined with the plentiful sunshine will help daytime highs rebound up into the mid/upper 70s on Sunday.
Cloud cover and light rain continue as the upper low continues to impact the eastern CONUS. The low will slowly progress eastward today, with light rain/drizzle possible through the day especially in the east. On Sunday the low should be off the east coast, and upper level ridging will start moving east in its place.
813 AM EDT Sat May 7 2022 Rain and cooler temperature expected through Saturday evening with the slow passage of a low pressure system. Stacked low pressure continues to slowly trudge eastward towards the Delmarva area this morning. As the low pulls off to the southeast, high pressure will slowly build throughout the day on Saturday, though clouds will be maintained under easterly flow. High pressure will build overnight Sunday, and clouds will dissipate. When combined with clear skies and light winds, the ridges and western PA will likely drop into the 30s.
Strong high pressure remains centered over eastern sections of Hudson Bay early this morning. with ridging extending into the Northern Great Lakes. High pressure center will continue to slowly drift eastward into Quebec over the next 24 hours. low pressure will continue to creep eastward out of the Ohio Valley. High temps this afternoon will again warm into the low to mid 60s.
653 AM EDT Sat May 7 2022 Low pressure was centered along the Virginia coast and will drift southeast today and tonight with scattered showers and isolated thunderstorms over the region. High pressure, along with cooler and drier weather build in for Sunday.
An approaching upper trough will also be joining the party, which will act to keep winds elevated across central NV. Sunday, as effects of the upper trough become more pronounced, a slight northerly component will be introduced into the upper flow in addition to the strengthening pressure gradient which will boost wind speeds for Sunday afternoon. Precipitation wise, as the upper trough starts its transit across NV, light valley rain and mountain snow showers will affect far northern Humboldt and Elko Counties Saturday afternoon. Precipitation is expected to transition to a wet snow for the higher elevation valleys for the overnight Saturday and again Sunday evening as cooler air arrives. Temperatures will be cooling through the weekend, with a large north to south gradient as the upper trough digs into NV.
A few lingering sprinkles/showers across the northeastern portion of the FA will diminish before daybreak as an upper level low moves further away. This, along with northwesterly winds, will keep temps a bit cooler across eastern areas with highs in the upper 60s. Western areas will be a bit warmer with highs in the lower 70s where breaks of sun are more likely in the afternoon. An upper level ridge begins to build across the area on Sunday allowing for more seasonable temps in the low to mid 70s.
More seasonable temperatures will return this afternoon with highs generally expected to warm into the low to mid 70s. A pattern shift will allow mid-level ridging to become largely dominant across the central CONUS. That ridge builds over the area today with the axis moving east by tomorrow.
This should help temps warm into the lower 70s, finally back to normal or slightly above for the first time this month. Certainly that area has the best chances for storms late tonight, but overall, think the severe threat is on the lower end this far east. The rainfall will be welcome though, with the highest amounts from one half to one inch falling where extreme drought remains. It's also in this area that has missed out on the higher rainfall amounts from the previous few days.
An upper level ridge will move into south Texas today and then move east into the western Gulf of Mexico on Sunday. An area of low pressure will develop over the Texas Panhandle to western Kansas tonight ahead of an upper trough over the northern and central Rockies.
947 AM EDT Sat May 7 2022 The weak ridging ranging from eastern Cuba into the southwestern Gulf of Mexico is promoting warm and calm weather across the Keys and local waters.
500 mb high pressure will gradually build farther northeast from neighboring Mexico and increasingly over the Lone Star State. This ridge will not only produce dry weather for the entire BRO CWFA, but will also generate well above normal daytime high and overnight low temperatures.
Much warmer, summer- like weather arrives going into the new week with most of the area expected to warm into the 80s to low 90s especially by midweek. Visible satellite imagery at 10am/15z shows the western edge of cloud cover associated with low pressure over the mid-Atlantic extends from roughly Indianapolis, IN, to Lawrenceville. Temperatures today will be warmer than the last several days with values in the middle to upper 60s expected, which will surely feel pleasant despite cooler northeast winds. Temperatures look to be a few degrees warmer on Sunday, though more cloud cover will be present and winds will be breezy.

1100 AM EDT Sat May 7 2022 Low pressure over West Virginia this morning will move southeast today. High pressure will then build in leading to a prolonged period of dry weather. The low pressure system to our east this morning will continue to drift east/southeast through the day. Northerly winds will be breezy across much of the area today, High pressure will start to build in through the period. It will be cool tonight with lows in the lower to mid 40s. This will occur as a strong Omega blocking pattern develops from the lower Mississippi River Valley northeast into the Great Lakes and beyond into eastern Canada.
Models depict a mid-level trough over the Atlantic states, with a mid low pushing an associated sfc frontal boundary into the Big Bend area of northern Florida. Temperatures remain on the warm side with afternoon highs in the low to mid 90s.
Band of mid and high clouds with the cold front continues to move south toward central California early this morning.
647 AM EDT Sat May 7 2022 Low pressure over West Virginia this morning will move southeast today. High pressure will then build in leading to a prolonged period of dry weather. Showers rotating around low pressure located in West Virginia continue to move across the eastern part of the forecast area. As the low pushes southeast, precipitation will diminish through the morning. Northerly winds will be breezy across much of the area today, High pressure will start to build in through the period. It will be cool tonight with lows in the lower to mid 40s. This will occur as a strong Omega blocking pattern develops from the lower Mississippi River Valley northeast into the Great Lakes and beyond into eastern Canada.
Any lingering influence of the low level thermal trough will give way to an increasing southerly 850 flow.
144 PM CDT Sat May 7 2022 /Updated at 1135 AM CDT Sat May 07 2022/ A low pressure system is slowly moving east towards the Atlantic Coast over the Carolinas. High temperatures will range from the lower 80s in the south to the upper 60s in the north where persistent cloud cover is causing cooler conditions. mostly clear skies and high pressure will allow temperatures to be more uniform through the day with high temperatures in the upper 70s and lower 80s.
