1051 AM EDT Thu Jun 9 2022 A cold front will pass across the region today into tonight, before stalling in the vicinity into the weekend. Fairly deep W-WSW flow in the low and mid levels will prevent the sea breeze from making much inland progress this afternoon. a little cooler than in recent nights. A cold front will stall in the vicinity on Friday. Highs are forecast to reach around 90 into the lower 90s closer to the Altamaha. A mid level trough will prevail over the eastern U.
757 AM EDT Thu Jun 9 2022 A weak cold front will cross the region today causing a few afternoon and evening showers and thunderstorms.
As a Pacific low pressure system deepens off the coast of British Colombia a warm southwesterly flow will develop resulting in the warmest day of the coming week. Expect upper 70s in Western Montana, while some locations in the lower Hells Canyon in west central Idaho will warm to the upper 80s.
Temps have already climbed into the upper 60s to low 70s, so highs on the warmer side in the mid to upper 70s still seem good. Area is west-northwest flow at 500 mb with 500 mb ridging ongoing into eastern Montana into eastern Saskatchewan. There are a couple of 500 mb short waves that will come over that ridge and then southeast thru the area the next 48 hours. As for temps today, went toward the 75th percentile on temps, a tad warmer than strict NBM.
A strong ridge of high pressure over Arizona will bring hot temperatures through this weekend. The hottest temperatures yet this season are in store, with Excessive Heat Warnings in effect for the lower elevations.
625 AM CDT Thu Jun 9 2022 (Today through Friday) Scattered showers are pushing south and exiting mid state region as surface cold front continues to push south of the I-40 Corridor. As a cold front continues to push south and eventually south of mid state region as these morning hours progress, clearing skies with dry and less humid conditions should prevail today. Coolest day of next seven days will be on Friday when highs span mid 70s to lower 80s as high pressure influences from our north try to build into mid state region.
632 AM CDT Thu Jun 9 2022 (Today) Light-moderate showers continue to spread southeastward across portions of the TN Valley this morning in the residual warm/moist sector airmass to the south of a cold front currently dropping through Middle TN.
High pressure will return to the area Thursday afternoon into Friday.
716 AM EDT Thu Jun 9 2022 A low pressure system is lifting through the area this morning, bringing rain showers.
642 AM CDT Thu Jun 9 2022 High pressure centered over eastern Nebraska and Kansas this morning will drift eastward through the day, ending up near the Mississippi/Ohio River confluence by 00Z this evening. A mostly sunny sky and strong June sunshine will push afternoon highs up to near normal in the low to mid 80s despite our cool start in the mid and upper 50s. The short wave will dig southeast through the Missouri Valley into the lower Ohio Valley overnight tonight into Friday afternoon. Carney The long wave pattern is amplified by Friday's system, with the trough over the eastern CONUS and a strengthening ridge across the Intermountain West.
A ridge builds in from the west this weekend bringing warm and dry conditions.
Once the fog burns off, a dry day is expected today with temperatures warming into the low to mid 80s.
Anderson (Issued 314 AM CDT Thu Jun 9 2022) Today through Friday: High pressure moving across the area has resulted in calm winds and clear skies. The recent rainfall and cooler temps has allowed for dense fog to develop across much of the area.
617 AM CDT Thu Jun 9 2022 For today, an area of low pressure to our southwest will bring a chance of showers and thunderstorms to mainly south central and southeastern South Dakota. Abundant low level moisture with dewpoints still in the low to mid 50s and light southerly winds could allow for fog to develop overnight into Friday morning.
To start off this forecast period, large-scale ridging dominates the Intermountain West, fairly weak troughing will have just moved through much of the Great Lakes region, leaving Upper Michigan in the middle as UL jet axis stretches from the Srn Manitoba/Ontario border across the heart of the Great Lakes region into the base of the aforementioned trough axis. By Friday, two ML lows will have succumbed to the Fujiwhara effect across the eastern portions of Canada, allowing for a trough axis to traverse across the U. In other words, all of this melds together to form a picture of some SHRAs developing, some containing lightning, but overall, still speaking on the low-end of chances.
As of 08Z surface analysis, the cold front that was responsible for this evening's showers and thunderstorms is slowly crossing through the forecast area. Otherwise, high pressure is building in behind the departing front. High pressure will continue to be present over the area but upper- level flow will usher below average temperatures into the region through the end of the period. Fog will be possible tonight as the area is expected to be under clear skies and cooler overnight temperatures.
1037 AM EDT Thu Jun 9 2022 A cold front crosses the area this afternoon, then stalls across the southeastern states tonight. High pressure builds into the area Friday.
617 AM CDT Thu Jun 9 2022 (Today and tonight) Expect temperatures to be a little cooler today and no heat hazards will be issued.
1023 AM EDT Thu Jun 9 2022 High pressure will build across the area today. There will still be a period of mostly cloudy skies into early afternoon until high pressure begins to build in. Highs will be in the lower to mid 70s. Upper level troughing remains entrenched on Friday night while a weak surface wave moves through the Ohio Valley.
404 AM CDT Thu Jun 9 2022 High pressure centered over eastern Nebraska and Kansas this morning will drift eastward through the day, ending up near the Mississippi/Ohio River confluence by 00Z this evening. A mostly sunny sky and strong June sunshine will push afternoon highs up to near normal in the low to mid 80s despite our cool start in the mid and upper 50s. The short wave will dig southeast through the Missouri Valley into the lower Ohio Valley overnight tonight into Friday afternoon. Carney The long wave pattern is amplified by Friday's system, with the trough over the eastern CONUS and a strengthening ridge across the Intermountain West.
936 AM EDT Thu Jun 9 2022 A cold front will stall to our south today. High pressure will build overhead tonight into Friday.
755 AM EDT Thu Jun 9 2022 A cold front exits east this morning yielding mainly dry conditions today and Friday. Farther south, a few showers and thunderstorms linger along convective outflow, with the surface cold front still working in the vicinity of the Ohio River. Aside from some lingering upslope showers, and perhaps a sprinkle or two out of some low-topped more vigorous cumulus (capped around H850-H800 as cold air undercuts the warm airmass in place) across the lowlands. Friday starts off dry as surface ridging moves across Kentucky and West Virginia. A parent low resides to the north of the region for the upcoming weekend, with a ridge building across the midwestern states.
However, a weak cold front remained over the heart of the CWA, and areas of dense fog and low stratus were expanding near this boundary across parts of central and northeast WI. Under partly cloudy skies, temperatures are expected to reach the lower to middle 70s at most locations.
612 AM EDT Thu Jun 9 2022 A cold front exits east this morning yielding mainly dry conditions today and Friday. Farther south, a few showers and thunderstorms linger along convective outflow, with the surface cold front still working in the vicinity of the Ohio River. Aside from some lingering upslope showers, and perhaps a sprinkle or two out of some low-topped more vigorous cumulus (capped around H850-H800 as cold air undercuts the warm airmass in place) across the lowlands. Friday starts off dry as surface ridging moves across Kentucky and West Virginia. A parent low resides to the north of the region for the upcoming weekend, with a ridge building across the midwestern states.
Area is west-northwest flow at 500 mb with 500 mb ridging ongoing into eastern Montana into eastern Saskatchewan. There are a couple of 500 mb short waves that will come over that ridge and then southeast thru the area the next 48 hours. As for temps today, went toward the 75th percentile on temps, a tad warmer than strict NBM.
646 AM EDT Thu Jun 9 2022 High pressure will build across the area today. Clouds will diminish this afternoon as weak high pressure builds in. Highs will be in the lower to mid 70s. Upper level troughing remains entrenched on Friday night while a weak surface wave moves through the Ohio Valley.
936 AM EDT Thu Jun 9 2022 High pressure will return to the area this afternoon into Friday.
High pressure will quickly move east of the area tonight, allowing for remnants of another plains storm complex to advect into west central Illinois late tonight through early tomorrow morning. Rainfall amounts will be quite light with the higher amounts of around 2-3 tenths of an inch along and south of I-74. A large area of high pressure will build into the region with very hot conditions.
Expect overnight lows in the low 70s with daytime highs in the low to mid 90s.
252 PM EDT Thu Jun 9 2022 A cold front stalls across the southeastern states tonight. High pressure builds into the area Friday.
Temperatures are seasonal in the low to mid 80s with comfortable humidity. Aloft, the Lower Mississippi Valley and Southeast remains entrenched in northwest flow.
332 PM EDT Thu Jun 9 2022 High pressure will build overhead tonight into Friday.
213 PM EDT Thu Jun 9 2022 High pressure will result in mainly dry conditions through much of today and Friday. It will be dry for the most part on Friday, but an H500 trough with ripples of vorticity arrive to the Middle Ohio Valley Friday evening, perhaps spreading some showers or storms. Expect below normal temperatures tonight and Friday with lows generally in the lower 50s, and highs in the upper 70s lowlands, ranging into the mid 60s highest elevations.
For today, an area of low pressure to our southwest will bring a chance of showers and thunderstorms to mainly south central and southeastern South Dakota. Abundant low level moisture with dewpoints still in the low to mid 50s and light southerly winds could allow for fog to develop overnight into Friday morning.
156 PM EDT Thu Jun 9 2022 High pressure will build across the area today. There will still be a period of mostly cloudy skies into early afternoon until high pressure begins to build in. Highs will be in the lower to mid 70s. Upper level troughing remains entrenched on Friday night while a weak surface wave moves through the Ohio Valley.
Overnight low temperatures wl fall into the low to mid 70s.
Cold air advection is expected to continue through the day, as an area of high pressure will slide eastward towards the Tennessee Valley. The expected location of more prevalent cloud cover and expected low level cold air advection should help to keep temperatures cooler today. Based on current temperatures, expect highs to reach the lower to mid 80s in locations that see more sunshine, mainly near/north of the TN river.
/issued 1019 AM CDT Thu Jun 9 2022/ Current forecast is on track with temperatures climbing into the low to mid 80s this afternoon. Unlike the past few days, today will be mostly dry and a little cooler across the Mid-South as a brief area of high pressure builds into the area.
133 PM EDT Thu Jun 9 2022 A cold front will pass across the region today into tonight, before stalling in the vicinity into the weekend. Fairly deep W-WSW flow in the low and mid levels will prevent the sea breeze from making much inland progress this afternoon. a little cooler than in recent nights. A cold front will stall in the vicinity on Friday. Highs are forecast to reach around 90 into the lower 90s closer to the Altamaha. A mid level trough will prevail over the eastern U.
Mid to upper level high pressure will remain the dominant feature throughout the short term period, thus, expect hot and humid conditions to prevail. Thus, although some spots could experience high temperatures peaking in the low 100s (mainly areas west of I-45 corridor), the combination of slightly more clouds and somewhat stronger mixing during the afternoon may be enough to keep heat indices just below Heat Advisory criteria.
Warmer temperatures, coupled with upper 60s/low 70s dewpoints will make for a hot and muggy afternoon.
Meanwhile, the low clouds from this morning are slowly continuing lift across the northeast Panhandles, which is allowing for temperatures to quickly warm across the western and southern Panhandles. A weak 850mb trough will push eastward this evening with the low level jet picking up across the eastern and southeastern Panhandles and hodographs showing better low level turning. However, a factor playing against that potential would be the loss of daytime heating and cooler surface temperatures. Tomorrow, the upper ridge starts to build east over the Panhandles with warming temperatures and dry conditions returning to the forecast area.
Showers are beginning to develop across southcentral Colorado/northcentral New Mexico under a weakness in the upper high. The upper high will build to our west over the Four Corners region.
This afternoon, we will continue to watch for convective development along a weak boundary currently sitting across the lower Mississippi River Valley.
Differential anticyclonic vorticity advection with confluent upper level flow will support surface ridging over Southeast Michigan tonight and throughout the day on Friday. Persistence of lowered geopotential heights/troughing and northwest flow bring modest potential for diurnal pop-up shower development Friday afternoon. It'll be difficult to have any sort of duration to convective activity with the background surface ridging. However, models are bullish on a scattershot convective response and the favorable arrival of main vorticity lobe/trough supports potential activity for all of Southeast Michigan. The upper level troughing continues to plague the central Great Lakes into this weekend.
350 PM EDT Thu Jun 9 2022 Once again, the Hudson Bay low and associated troughing over the eastern US is the driver of the weather stories for the short term in the Upper Peninsula. Borderline elevated fire conditions are possible in the west on Friday afternoon when temperatures will be in the low 70s, RHs will be in the mid 20s to 30%, and wind will be less than 15 knots.
1019 AM CDT Thu Jun 9 2022 Current forecast is on track with temperatures climbing into the low to mid 80s this afternoon. Unlike the past few days, today will be mostly dry and a little cooler across the Mid-South as a brief area of high pressure builds into the area.
303 PM EDT Thu Jun 9 2022 High pressure crossing the Ohio Valley tonight will bring nearly calm winds and temperatures about 5 degrees cooler than normal. Clouds will increase on Friday ahead of an upper trough coming in from the west.
The mid level ridge axis from south of the Four Corners region to the Middle Texas coast will generally remain in place through the period. Building high pressure will lead to slightly warmer highs on Friday. Lows will range from the mid 70s inland to the lower 80s coast tonight and Friday night.
1252 PM CDT Thu Jun 9 2022 (Today and tonight) Expect temperatures to be a little cooler today and no heat hazards will be issued.
Dew points have been a bit slow to mix down today and are still in the upper 60s and low 70s as of 18Z, except for in the Hill Country where they're in the low to mid 60s. A Heat Advisory will be in place 1pm-7pm for all areas except the western Hill Country due to slightly cooler temps/heat indices, but also the Rio Grande Plains and Val Verde County due to higher criteria.
Flow will increase in the low to mid levels which should allow for showers and thunderstorms to expand in coverage. While instability will be on the lower side, CAPE values roughly 500-1000 J/kg, there is some decent 0-3km and 0-6km shear which may allow for some short lived stronger updrafts to develop. Confidence is pretty low as the 18z CAPE analysis is running on the lower side.
Temperatures will be mild tonight, with overnight lows in the low to mid 70s, with highs on Friday between 99 and 103 degrees.
Dry high pressure will keep things nice through tonight with most areas dropping into the 50s with decreasing winds.
Ridging at the midlevels will continue to keep warm and dry weather in place through the period across Deep South Texas and the Rio Grande Valley. Highs on Friday will be just a touch warmer in spots than today, rising into the upper 90s to low 100s inland with 80s to low 90s along the coast.
Unfortunately, CAMs donât agree well on location of the highest threat, but there is fairly high confidence that the peak severe timing will be roughly 4pm to 1am. Friday should remain dry as upper ridging moves overhead.
356 PM EDT Thu Jun 9 2022 High pressure will move east across the area tonight. It will be cool with lows in the lower to mid 50s. On Friday, the high will move east. For Friday night, this period should have the highest chance for showers/embedded thunder as available dynamics are the greatest.
1233 PM EDT Thu Jun 9 2022 High pressure will result in mainly dry conditions through much of today and Friday. Farther south, a few showers and thunderstorms linger along convective outflow, with the surface cold front still working in the vicinity of the Ohio River. Aside from some lingering upslope showers, and perhaps a sprinkle or two out of some low-topped more vigorous cumulus (capped around H850-H800 as cold air undercuts the warm airmass in place) across the lowlands. Friday starts off dry as surface ridging moves across Kentucky and West Virginia. A parent low resides to the north of the region for the upcoming weekend, with a ridge building across the midwestern states.
Thus, if showers are less aggressive or stay north or south of the area it is possible temperatures could be warmer. If showers are more widespread across central and southern Wisconsin, it may end up cooler.
257 PM EDT Thu Jun 9 2022 Quiet weather was across central Indiana this afternoon with high pressure briefly building into the area. The upper trough and upper energy will move through this afternoon into early evening. On Friday, the upper trough will move into the area. Isentropic lift will ramp up as the trough moves in, and the area will be in the left exit region of an upper jet streak.
MCS will shift south across northeast Louisiana as it rides along the eastern periphery of the established upper-ridge. Temperatures across much of southeast Oklahoma, southwest Arkansas, and north Louisiana will experience much cooler temperatures in the upper 80s due to an ambient cooler airmass in place north and east of the frontal boundary along with increased cloud cover from the remnant MCS.
A cold front continues to drift southward through the forecast area this afternoon with the impetus for isolated to scattered convective development ahead of this front. Drier air will filter southward across the area tonight behind the cold front, with dewpoints dipping into the 50s across the area and persisting through the day Friday. For Friday night, opted to continue to indicate a return of low-end PoPs as an MCS works southeastward into the Lower Mississippi Valley, though confidence is low regarding any impact locally.
This afternoon through Friday night The ridge will begin to rebuild over the region today, with the axis being centered over eastern ID into MT.
The frontal passage that dried us out will give us Friday morning lows a few degrees below normal to pair with the lower dewpoints, as northwest flow controls the area.
As the upper-level wave departs, weak high pressure will build into the area at the surface. Any lingering storms should not be severe, but given the steep low-mid level lapse rates and low freezing level (about 8200 ft), small hail has been reported and is still possible with the stronger storms.
Upper ridge remains in place with weak warming trend continuing over East Idaho. Breakdown of the upper ridge begins on Friday, with potential for a few showers to creep into the Frank Church regions of the central mountains late Friday afternoon.
Northwesterly flow aloft will continue over our region through the period as an upper-level ridge remains anchored over the Southwestern US and upper-level troughing remains over the Northeast US. At the surface, low pressure over the Northeast US will continue lifting northeast. Highs will generally be in the low to mid 90s across the region with heat indices likely approaching the upper 90s to lower 100s for many locations. Lows tonight will be in the upper 60s north and the low to mid 70s for points south.
The low clouds from this morning are just above out of GUY, which will put all three sites in VFR conditions.
A cold front that is pushing through the southeast has caused the upper level ridging south of our area.
Tonight and Friday will be dry with variable mid and high clouds, as flat ridge remains in place and moisture streams thru the PacNW and northern Rockies. Temps tomorrow, clouds permitting, should reach the low-mid 80s most places.
Friday is shaping up to be a pleasantly warm and dry day with an upper level ridge building to our west. This ridge remains in place over the weekend, bringing with it warm and dry conditions.
Upper level heights will be on the rise this weekend as upper ridging overspreads the Central US.
221 PM CDT Thu Jun 9 2022 High pressure slides across the FA tonight, with its clear/dry airmass and dew points nicely in the 50s. With the ridge axis to the east tmrw, a soon-to-follow northwest flow short wave dives out of the southern Plains, and beelines toward its consistently modeled track into the Lower Mississippi River Valley during the day.
248 PM EDT Thu Jun 9 2022 Water vapor highlights an upper-level low slowly sliding to the south of western Cuba, as well as an extensive mid-latitude trough stretching across the eastern United States. This trough is blocking the ridge extending across the western Atlantic from lifting northward, which has put the Florida Keys along the ridge axis.
151 PM EDT Thu Jun 9 2022 Low pressure will exit across northern New England this evening, with some showers lingering across the region. High pressure will build in from the Ohio valley and promote the return to fair dry weather during Friday.
340 PM EDT Thu Jun 9 2022 Discussion/Marine -- Showers/storms over Central Lower Michigan this evening -- Showers and storms have initiated this afternoon near a cold front with instability pooled near it.
High temperatures for this afternoon will reach into the lower 90s with overnight low temps expected to drop down into the lower 70s over inland areas and in the mid 70s for coastal areas and locations nearer to north central Florida.
927 AM PDT Thu Jun 9 2022 Warming will continue into the weekend with hot weather for inland areas while coastal areas remain cooler and cloudier.
140 PM EDT Thu Jun 9 2022 High pressure will return to the area this afternoon into Friday.
To start the period, the area sits under the northern extent of a lowly amplified southwest CONUS ridge.
Latest CAMs continue to indicate more organized storm development over central Nebraska after 00z in association with a surface cold front and expand these storms, which should remain elevated across our area, eastward into portions of eastern Nebraska through the overnight hours. Mostly dry conditions are expected through the weekend as a midlevel ridge builds into the central Plains.
801 PM EDT Thu Jun 9 2022 Aviation -- Showers/storms over Central Lower Michigan this evening -- Showers and storms have initiated this afternoon near a cold front with instability pooled near it.
