1252 AM PDT Sat Jun 4 2022 Cooler afternoon highs today as onshore flow continues. Northwest breeze and cooler conditions prevail this morning as onshore flow continues. This afternoon a light shower or two will be possible around YNP as some of the moisture from the trough to our north and associated lift reach the area. As the Pacific Northwest trough begins to lift out of that area tomorrow, afternoon highs will begin to increase.
329 AM EDT Sat Jun 4 2022 Dry high pressure will build across the region through the weekend. High pressure will slide through the northeastern CONUS, while the tropical system pushes offshore to the east Saturday night. As of 310 am EDT Saturday: Surface ridging will remain in place across the region through the period, albeit in a slowly weakening phase. Clouds have scattered out over much of the mountains and foothills as high pressure over the Great Lakes region continues to pump in drier air. Outlook: Dry high pressure remains over the area Sunday.
Another great day is on top tomorrow and while it'll be a little warmer, the dry air sticks around one more day. This high will very slowly move eastward through the weekend and provide dry and nice weather tonight and through Saturday.
340 AM CDT Sat Jun 4 2022 Warm and dry weather will prevail across central Illinois today as afternoon high temperatures top out in the lower to middle 80s. with readings ranging from the middle to upper 30s along/north of a Bloomington to Champaign line to the lower to middle 50s south of the front. Further south, am expecting a warm/dry day across the KILX CWA with high temperatures once again reaching the lower to middle 80s.
103 AM EDT Sat Jun 4 2022 A seasonably cooler, less humid, and very pleasant stretch of weather will continue across Central PA through Sunday. A weak mid/upper level trough/CFA was drifting SE across the Lower Susq Valley and South-Central PA early this evening accompanied by some alto cu clouds (that earlier produced some light showers across the Laurel Highlands). A weak sfc cold front pushing across Central Lake Erie and Northern Ohio could bring a few clouds across the Northern and Western Mountains overnight, but look for gradual clearing of Alto CU and CS clouds from the SE 1/2 of the CWA late this evening with mainly clear skies to follow for late tonight.
In its wake is much cooler temperatures, and hence very reduced to no instability. TWH Sunday weakening upper level ridging over the area but pattern is a bit blocky as Montana is in between two upper lows.
The higher potential for additional showers/storms will possibly be late this evening into early Sunday. Lows will then fall into the low to mid 60s tonight into early Sunday.
Low temperatures will again run in the lower to mid 50s. This thanks to a stubborn area of upper level low pressure lingering over central and eastern Canada.
A weak area of high pressure sits over WI and lower MI early this morning.
317 AM EDT Sat Jun 4 2022 A cold front will settle further south and east reaching the coast tonight. High pressure will build over the Mid Atlantic region over the weekend.
High pressure at the surface will continue to settle over the region tonight. This will result in a quiet night, with slightly cooler conditions compared to the past few nights. With mostly clear skies expected and possibly some patchy ground fog developing around day break Saturday, particularly across the Pine Belt, lows will fall into the low and middle 60s.
A prominent and persistent upper level closed low pressure system that has been pushing moisture from the Pacific into the northwestern U.
130 AM EDT Sat Jun 4 2022 A weak front will push through the region tonight and Saturday with high pressure settling across the Great Lakes. Warmer Sunday with increasing clouds and a chance of showers north of Route 6.
Temperatures ranged from the mid 70s along the Highway 20 corridor to the lower 80s south of Interstate 80. A sprawling closed low sits on the western side of the Hudson Bay in northern Canada resulting in northwest flow aloft across the Upper Midwest.
Expect lows tonight around 70 with highs tomorrow in the lower 90s. Slightly breezy conditions are possible across inland areas as an elevated pressure gradient from the leftovers of Potential Tropical Cyclone remains in place.
Potential Tropical Cyclone One should have little influence on the area as it tracks across southern/central FL today then off the Carolina coast for Sunday.
As expected, showers and isolated thunderstorms from Potential Tropical Cyclone (PTC ONE) convection, which was over Cuba and the Straits of Florida last night, affected most of the Keys this morning and produced moderate to heavy rainfall. Potential Tropical Cyclone remains disorganized with multiple centers and dry air entrainment as shown by the GOES-16 lower, middle, and upper water vapor imagery. 35 exhibits a moist plume of showers just south of Cuba that will lift northeast with the broad trough today. At this time, the dry air advecting into the Lower Keys will give the area a brief reprieve to the moderate to heavy rainfall for few hours.
Discussion: The southern Appalachian region will remain beneath broad, weakly cyclonic flow aloft today and tonight, with an H85 ridge just to our north and light northerly flow at the surface. Not really expecting anything beyond some typical summertime CU development there, but also hard to ignore the high res guidance hinting at a few isolated showers. The H85 flow will be easterly thanks to the low level ridge to our north, so there will be an upslope component on the east side of the TN/NC line to assist in CU development or potential showers.
313 AM CDT Sat Jun 4 2022 Western and central North Dakota remains in northwest flow aloft with a ridge axis to our west and a closed low to our northeast over northeastern Manitoba. A weak disturbance will continue to skirt our southwest as it moves through the ridge. The ridge axis will continue to nudge closer through the day, approaching the North Dakota/Montana border tonight as it deamplifies. The next stronger wave then approaches tonight as it flattens the ridge, transitioning our area into zonal flow aloft.
Highs will be a bit cooler, generally in the upper 50s near the International Border, with upper 60s in the southern portions of the Red River Valley.
1245 AM EDT Sat Jun 4 2022 Dry weather is expected through the weekend under high pressure.
130 AM EDT Sat Jun 4 2022 A cold front will settle further south and east reaching the coast tonight. High pressure will build over the Mid Atlantic region over the weekend.
215 AM EDT Sat Jun 4 2022 A cold front will bring thunderstorms tonight. More seasonable weather is slated for the weekend as high pressure builds in from the north. Ongoing thunderstorms ahead of a cold front this evening will continue with elevated instability. With the moisture in the lowest levels of the atmosphere and cool air advection moving into the area, a cloudy start on Saturday seems likely with ground fog possible in areas receiving heavier rain. Temperatures will be much cooler than previous days with highs only in the low to mid 80s. A few isolated showers are possible during the afternoon due to a stationary front offshore holding its position close to the SC coast and a weak mid-level trough parked overhead. High pressure builds from the north behind the near term frontal boundary.
As mentioned in the previous forecast, mid-level ridging will bring warmer temperatures this weekend but the CWA is expected to stay below Heat Advisory criteria. Decided to go with the NBM and have highs in the mid 90s in the RGV and lower 100s out west with highs slightly warmer by 2 to 3 degrees on Sunday.
624 AM EDT Sat Jun 4 2022 High pressure has built in with sunny skies expected today along with dry conditions.
628 AM CDT Sat Jun 4 2022 Northwest flow aloft continues today with high pressure at the surface gradually shifting eastward. This will gradually allow a southerly wind to develop with temperatures warming a degree or two warmer than they were yesterday. Thunderstorm activity today should be confined to areas far to the west where better moisture return exists just east of the dryline in western Kansas as well as along a warm front developing across Nebraska into Iowa. There's an outside chance of a shower developing in the northwest part of our area overnight tonight, but otherwise it should be another quiet night with lows a bit warmer than this morning due to a bit better moisture and low level wind flow. We'll see a bit more cloud cover with highs in the low to mid 80s.
541 AM CDT Sat Jun 4 2022 Warm and dry weather will prevail across central Illinois today as afternoon high temperatures top out in the lower to middle 80s. with readings ranging from the middle to upper 30s along/north of a Bloomington to Champaign line to the lower to middle 50s south of the front. Further south, am expecting a warm/dry day across the KILX CWA with high temperatures once again reaching the lower to middle 80s.
At the sfc, we are under the influence of high pressure across the Mid MS Valley/OH Valley that will keep us dry and provide NE winds 5-10 mph. Aloft, we are in more of a WNW flow that will slide in upper level clouds today, but that should not affect temps reaching the low/mid 80s.
907 AM EDT Sat Jun 4 2022 Dry high pressure will control the weather pattern across the region though the weekend.
358 AM MDT Sat Jun 4 2022 Weak ridging has moved into the area this morning, and the associated subsidence is causing mostly clear skies during the early AM hours. Shear will be weak under the larger scale ridge aloft, so severe storms are not a primary concern, but lightning and small hail are possible for most locations at some point during the afternoon and evening.
621 AM EDT Sat Jun 4 2022 Dry high pressure will build across the region through the weekend. High pressure will slide through the northeastern CONUS, while the tropical system pushes further offshore to the east Saturday night. As of 310 am EDT Saturday: Surface ridging will remain in place across the region through the period, albeit in a slowly weakening phase. Clouds have scattered out over much of the area as high pressure over the Great Lakes region continues to pump in drier air. Outlook: Dry high pressure remains over the area Sunday.
539 AM EDT Sat Jun 4 2022 Dry weather is expected through the weekend under high pressure.
906 AM EDT Sat Jun 4 2022 High pressure will result in dry and seasonable conditions through the weekend.
1044 AM EDT Sat Jun 4 2022 Dry high pressure will build across the region through the weekend. As of 1035 AM EDT Saturday: A cooler and drier air mass will be in place over the area today with east to northeast flow as we're between a high pressure center over the Great Lakes region and a tropical system moving east of the southern FL Peninsula. High pressure will slide through the northeastern CONUS, while the tropical system pushes further offshore to the east Saturday night. As of 310 am EDT Saturday: Surface ridging will remain in place across the region through the period, albeit in a slowly weakening phase. At KCLT and elsewhere: High pressure over the Great Lakes region continues to pump drier air into the area. Outlook: Dry high pressure remains over the area Sunday.
Down at the surface, high pressure will build in over the Appalachians through the day today as Potential Tropical Cyclone one moves over the southern Florida Peninsula and out over the western Atlantic. Sunday will also be warm, as highs reach the lower to mid 90s north of I-10 and the upper 80s south of I-10. Lastly, swell associated with Potential Tropical Cyclone One will persist at the Alabama and western Florida Panhandle beaches through Sunday morning. The increased swell will keep the HIGH RISK of rip currents at area beaches through at least Sunday morning.
This will translate to warming temperatures along with the typical afternoon southwest breezes each afternoon with some gusts around 25 to 30 mph, though winds will be stronger in areas influenced by the higher terrain. This will put us under a ridge, which will help to usher in much warmer air and increases our daytime highs.
Massive close low in the eastern Pacific off the OR coast is rotating a trough through eastern OR right now and this will pass through the forecast area from midday onwards until it passes through this evening. There is enough moisture and instability to generate showers and isolated thunderstorms during the afternoon and evening--primarily in the central Idaho mountains, and the highlands against the MT and WY borders. The main low ejects another trough that arrives Sun.
1039 AM EDT Sat Jun 4 2022 High pressure will continue to dominate our weather this afternoon with sunny skies and mild temperatures expected.
A series of weather disturbances continue to rotate around and out of the upper level low pressure system off the coast. This surge of moisture will produce around another quarter of an inch in the low elevations and half to one inch plus in the mountains overnight through early Sunday before it exits.
Today: High pressure will continue to shift off to the east of the area this morning, which will allow a more moist southerly flow to develop into the area. This may be enhanced, to some extent, by a weak trough/frontal boundary sagging southeast into northwest Wisconsin by mid afternoon. The main concern across the north is the potential for gusty winds under the showers or isolated storms as sounding continue to show an inverted-V in the lower levels.
626 AM CDT Sat Jun 4 2022 An upper-level low north of the Minnesota/Canada border and a low- amplitude upper-level ridge across the Rockies will be present through the short term period, and this will result in an unsettled pattern with near to below normal temperatures. Nonetheless, temperatures will climb into the low to mid 70s.
629 AM CDT Sat Jun 4 2022 (Today) Light west-northwest winds aloft will persist across the TN Valley today, within the flow to the south of an elongated mid- level trough extending from eastern Manitoba into western Quebec.
Skies are expected to remain VFR outside of the low clouds this morning and the thunderstorms this afternoon and evening. /Issued 331 AM CDT Sat Jun 4 2022/ Another upper level short wave trough is expected to move across the Panhandles late this afternoon and this evening. The trough/dryline, upper level disturbance, and the possibility of a leftover outflow boundary may all provide enough lift to get some thunderstorms going. Sunday looks dry for now across the Panhandles as the next short wave trough move north of the area.
308 AM MDT Sat Jun 4 2022 Current surface analysis shows one frontal boundary just south of the forecast area, with a weakening cold front to the north across ND. Upper level analysis shows weakening ridge over the northern Rockies, with low pressure off the British Columbia coast. Temps will be cooler across northern and eastern areas with more clouds around, highs ranging from the upper 50s over far northwest SD to the 70s across far southwest SD. The best chance for severe wx will likely be across far southern SD, where more sun and warmer temps later in the afternoon could lead to a more favorable environment for isolated severe storms.
Western and central North Dakota remains in northwest flow aloft with a ridge axis to our west and a closed low to our northeast over northeastern Manitoba. A weak disturbance will continue to skirt our southwest as it moves through the ridge. The ridge axis will continue to nudge closer through the day, approaching the North Dakota/Montana border tonight as it deamplifies. The next stronger wave then approaches tonight as it flattens the ridge, transitioning our area into zonal flow aloft.
552 AM MDT Sat Jun 4 2022 Weak ridging has moved into the area this morning, and the associated subsidence is causing mostly clear skies during the early AM hours. Shear will be weak under the larger scale ridge aloft, so severe storms are not a primary concern, but lightning and small hail are possible for most locations at some point during the afternoon and evening.
(Today) Light west-northwest winds aloft will persist across the TN Valley today, within the flow to the south of an elongated mid- level trough extending from eastern Manitoba into western Quebec.
An upper-level trough and cold front will bring showers to northern Nevada today with more widespread showers and thunderstorms mainly along and north of I-80 Sunday.
447 AM MDT Sat Jun 4 2022 Current surface analysis shows one frontal boundary just south of the forecast area, with a weakening cold front to the north across ND. Upper level analysis shows weakening ridge over the northern Rockies, with low pressure off the British Columbia coast. Temps will be cooler across northern and eastern areas with more clouds around, highs ranging from the upper 50s over far northwest SD to the 70s across far southwest SD. The best chance for severe wx will likely be across far southern SD, where more sun and warmer temps later in the afternoon could lead to a more favorable environment for isolated severe storms.
659 AM EDT Sat Jun 4 2022 Dry high pressure will control the weather pattern across the region though the weekend.
621 AM EDT Sat Jun 4 2022 High pressure will result in dry and seasonable conditions through the weekend.
Models have winds turning offshore near the lake for a time late morning into the afternoon, but wondering if winds might just stay onshore through the day given the cooler lake temps.
Warm air advection combined with weak ridging will help to bring mostly sunny skies and highs into the mid 80s across much of the lower elevations with 60s and 70s expected in the high country. By Saturday evening upper ridging will increase with convection pushing east, with party cloudy conditions and mild overnight temperatures. Sunday will likely be one of the drier days as lee troughing pushes east and scours the theta-e axis into Nebraska and Kansas. We do expect a weak backdoor cold front to move across the plains Sunday night.
300 PM MDT Sat Jun 4 2022 Overall, no major changes to the short term forecast with an upper level low remaining nearly stationary across Ontario, and as a result, zonal flow dominating the upper levels with several short wave disturbances propagating within the flow.
1038 AM CDT Sat Jun 4 2022 Warm and dry weather will prevail across central Illinois today as afternoon high temperatures top out in the lower to middle 80s. with readings ranging from the middle to upper 30s along/north of a Bloomington to Champaign line to the lower to middle 50s south of the front. Further south, am expecting a warm/dry day across the KILX CWA with high temperatures once again reaching the lower to middle 80s.
322 PM EDT Sat Jun 4 2022 Dry high pressure will control the weather pattern across the region through the weekend.
Forecast area appears to remain under the influence of cyclonic shear side of semi-persistent trough extending from Quebec into northern plains.
However, fcst soundings are quite consistent with the presence of a subsidence ridge which would tend to suppress convection. Longitudinally-elongated mid/upper-level ridging will dominate the pattern for the first half of the upcoming work week as flow across Canada and into the polar regions de-amplifies.
Additionally, there will likely be storms that form in the high plains of southwestern NE and western KS near the front and dry line.
The "center" of Potential Tropical Cyclone One (PTC 1) moved onshore near Naples, FL around 7 AM this morning. Due to the cloudy rainy conditions, temperatures today will be below normal for this time of year, with highs in the low 80s.
However, upper level ridge is starting to build into the area and inhibition has increased. Still suspect that we will see some storms west of the Pecos in the higher elevations and perhaps a few along a developing dryline across the Permian Basin, with the convection shifting east or southeast into the western Concho Valley and Big Country. Ridge builds into the area in earnest tomorrow and temperatures begin to soar.
pleasant weather abounds across the CWA with temps in the low 80s and dew points in the low to mid 50s. Otherwise the Massie Rose 1000-850 mb thickness technique yields mid 80s for highs, cooler in NE Bluegrass, and warmest from Beaver Dam to Russellville. looks to be a active period with zonal, progressive upper level flow from Great Plains to the Ohio Valley with 588 dm upper ridge over the Lone Star State.
148 PM PDT Sat Jun 4 2022 Cooler afternoon highs today as onshore flow continues.
232 PM MDT Sat Jun 4 2022 The weak ridge axis is slowly shifting east across eastern WY this afternoon, putting western WY in a better overall position for lift. Vorts trying to crest the minimal ridge, along with diffluence, are providing enough midlevel lift to bring another day of scattered showers and thunderstorms.
1229 PM CDT Sat Jun 4 2022 Warm and dry weather will prevail across central Illinois today as afternoon high temperatures top out in the lower to middle 80s. with readings ranging from the middle to upper 30s along/north of a Bloomington to Champaign line to the lower to middle 50s south of the front. Further south, am expecting a warm/dry day across the KILX CWA with high temperatures once again reaching the lower to middle 80s.
This is a result of a combination of shifting winds due to an incoming trough, surface ridging moving away from the East Coast, and an quasi-stationary frontal boundary that will slowly wander northeastward. By Sunday night, moist southerly flow, along with a stationary front over the area, will bring dew points back over the mid-60s area wide, ensuring milder minimum temperatures in the lower 70s.
1133 AM MDT Sat Jun 4 2022 Current surface analysis shows one frontal boundary just south of the forecast area, with a weakening cold front to the north across ND. Upper level analysis shows weakening ridge over the northern Rockies, with low pressure off the British Columbia coast. Temps will be cooler across northern and eastern areas with more clouds around, highs ranging from the upper 50s over far northwest SD to the 70s across far southwest SD. The best chance for severe wx will likely be across far southern SD, where more sun and warmer temps later in the afternoon could lead to a more favorable environment for isolated severe storms.
245 PM EDT Sat Jun 4 2022 Latest surface analysis shows Potential Tropical Cyclone One moving across South Florida this afternoon, a stationary front across the northern Gulf over to the SE coast, and another stationary front north of our area over portions of the OH valley. At the upper levels, there are a couple areas of low pressure over central and eastern Canada, with nearly zonal flow aloft locally. Low temps will be in the lower to middle 50s, with some patchy river valley fog developing towards morning.
1008 AM MDT Sat Jun 4 2022 Synoptic Setup: A closed low of modified Arctic air currently lies over central Manitoba. A ridge anchored over the Desert Southwest runs north through western Montana and the Front Range of Alberta and British Columbia. To the West, another closed low lies over the coast of British Columbia. The ridge is currently pinched around northwestern Montana providing a weak point for disturbances to break off of the BC low and run along the International Border into northeast Montana where they can provide brief shots at lift and rain. In addition the low over northern Manitoba has a significant influence from it's airmass reaching southwest all the way over the high plains of Montana at times.
(Tonight) At the sfc, we will be under the influence of high pressure, slacking NE winds and keeping conditions dry. Overnight lows will still be a little cool, in the lower 60s with a few spots reaching the upper 50s.
231 PM CDT Sat Jun 4 2022 An upper low remains off to the north, with ridging over the Rockies. Underneath the low there remains a relatively active fast flow over the forecast area during the short range. Temperatures on Sunday will be cooler than normal given all the clouds and pcpn.
