1110 PM CDT Fri Aug 9 2024 High pressure will move across the Mid-Mississippi Valley over the weekend bringing dry weather and below normal temperatures for the Mid-South.
(Today through Sunday) Key Messages: - Heat Advisory in effect for the Coastal Bend - Moderate to major risk of heat-related impacts this weekend Water vapor imagery this morning reveals an upper level ridge in place across the Southern Plains and an upper trough moving across the Great Lakes. Upper level ridging remains in control on Sunday. Feel confident in the low risk today but will need to monitor the coast through the day in case we need to bump up to a moderate risk.
Broad sfc ridging sliding up the the Ohio river valley will result in dry conditions today, with highs topping out slightly below normal as an upper trough moves over SE Canada. __________________________________________________________ Mostly dry weather will continue with the mentioned high pressure largely in control. Temperatures will run a couple degrees below average underneath the troughing pattern.
1228 AM CDT Sat Aug 10 2024 (This evening through Sunday night) A very dry and stable deep layer ridge axis will continue to remain just west of the area through Sunday night, and this will keep any rain chances at bay as light northerly flow and dry air advection persists.
Temperatures won't be hot, but they'll return to the Low 80s which is close to normal for Western Michigan this time of year. In general the weather pattern will be dominated by a slowly building upper level ridge to our east, which sets us up under pleasant northwesterly flow. On Sunday there is a steady decrease in the 925/850 mb winds as the low pulls away.
Highs will reach the mid/upper 90s with the higher of that range in the Florida panhandle.
411 AM EDT Sat Aug 10 2024 (Today through Sunday) Upper level low over the Great Lakes Region has absorbed Debby over the NE CONUS (finally) and will continue to slowly meander over the weekend to the south and east towards upstate NY.
(Today through Sunday) Big picture wise, in the upper levels we have a fairly strong low centered over southeast Canada just north of the Great Lakes with a shallow trough over the upper midwest into the Ohio Valley. The remnants of Debby are pretty well gone being absorbed into the front over New England associated with the low. Over the southwest is a and extending across the southern US and down into the Mexico and the Gulf of Mexico is a dome of high pressure. 5 range and Td in the low to mid 70s are indicative of the overall dry atmosphere. While the high pressure will push temperatures into the upper 90s, the lower humidities will keep the apparent temperatures in the low 100s below the threshold for heat headlines.
Temperatures will be near normal, and chances for precipitation will remain in the higher terrain and along the Continental Divide.
A few weak ripples in the flow will slide southeast on the periphery of the closed upper low over Ontario that will slowly move east through the weekend.
1006 PM CDT Fri Aug 9 2024 (This afternoon through Saturday night) The "cold front" has made it to roughly the Pecos River valley with temperatures north of this boundary some 10 to 15 degrees cooler than yesterday. Saturday, look for temperatures to be slightly above normal for this time of year, ranging from the mid 80s at higher elevations to the mid 90s to around 107 across the lowlands.
- Warmer on Sunday with less coverage of showers and storms. With more sunshine, temperatures will be warmer as well, returning to normal levels in much of the area.
Despite a lack of insulation, observation stations along the Keys are clocking in temperatures in the lower to mid 80s with dewpoints in the mid to upper 70s. The ridge axis that influences our winds is currently nosed right over the Keys resulting in our light southerly flow. As this ridge lifts north throughout the day, breezes will back to the southeast before freshening later tonight as it settles over the Florida Peninsula.
1244 AM CDT Sat Aug 10 2024 (This evening through Sunday) Mostly calm and dry conditions are expected through the period as high pressure controls the weather pattern. With that said, NW flow aloft will bring cooler temperatures through the weekend.
1219 AM CDT Sat Aug 10 2024 A stable pattern, characterized by strong upper-level ridging centered over Texas, will maintain dry conditions through tonight. In terms of rain chances, the vast majority of the region will be dry as the center of the upper-level ridge axis just off to our west remains anchored across Texas. The possible exception will be over our far NW zones along the Ouachitas where disturbances in NW flow riding around the top of the ridge may bring isolated showers and a few thunderstorms this weekend.
Easterly and northeasterly surface winds will continue to advect some cooler and drier air into the region. The lower dewpoints and cooler temperatures should keep heat index values well below advisory criteria today.
An upper low will meander around southeast Ontario and southwest Quebec during the period, with a broad trough around it over much of the eastern CONUS. The combo of the upper trough and northwest low level flow east of the approaching high will bring relatively cool and dry air to the area by summertime standards. The forecast period starts with the forecast area at the base of a longwave trough that's slowly beginning to exit the region. At the surface, high pressure will be in place and the area will experience dry weather. At the base of the trough, west to northwesterly flow will advect cooler air into the region which will keep temperatures overnight Sunday below average as lows are forecast to be in the lower-50s in the valleys and upper-50s on the ridgetops.
250 AM EDT Sat Aug 10 2024 - Breezy and cooler today with westerly wind gusts around 30 mph. Large upper level low/trough encompassing Central Canada south into the Midwest/Great Lakes region, with at least 3 distinct upper level waves/mid level cold pools rotating around.
Mid-upper level low north of Lake Superior will slowly shift to eastern Canada by early this week. One more cooler and breezy day today (mid 60s north to lower 70s elsewhere) with some lake effect showers over northern WI, then temperatures will return to normal or slightly above normal Sunday through the upcoming week with many days seeing highs in the upper 70s to lower 80s. No widespread rain is expected this week as high pressure that arrives over the areas on Sunday will only slowly depart mid to late week.
However, as far as C AL is concerned, it will generally be stalled just SE of Pike/Barbour with ridging behind the boundary across much of ERN Conus. Temperatures will remain warm during the short term for highs (mid/upper 80s far N to mid/upper 90s far S), but with the lower dew points trickling in, heat indices should remain below that which would require heat advisories.
1213 AM CDT Sat Aug 10 2024 (Tonight through Saturday night) Key Messages: - Heat Advisory in effect this afternoon - Moderate to Major risk of heat related impacts today and tomorrow Mid to upper-level ridging will maintain hot and dry conditions across South Texas. The primary concern is the heat, with highs ranging from the low 90s along the coast to around 105 degrees inland.
121 AM EDT Sat Aug 10 2024 - Dry weather and cooler than normal conditions persist this weekend. Several weak perturbations will continue to rotate around parent upper low centered across northern Great Lakes/south central Ontario. Saturday will feature the coolest conditions of this forecast period with highs only reaching into the low to mid 70s. Great Lakes/southern Ontario negative upper height anomaly will finally push into eastern Great Lakes/southern Quebec by Sunday morning, but upstream omega-blocking pattern across south central Canada will keep any notable low level warm/moist advection return displaced well west and south of the local area.
255 AM EDT Sat Aug 10 2024 * Very pleasant weekend with cooler temperatures and lower humidity. Below normal temperatures and dry weather will continue into the second half of the weekend as an upper level trough will remain over the eastern one-third of North America. With the center of high pressure still slightly NW of the area on Sunday, light NW flow in the low-levels and a lack of significant height increases will keep temperatures fairly similar to Saturday, possibly adding 1 to 2 degrees as CAA wanes.
(Today through Sunday afternoon) WV imagery this morning shows the upper ridge covering the southwest and central CONUS, extending from the eastern Pacific to the ArklaTex and into the Gulf of Mexico. The old inverted trough is now over Baja, bifurcating the ridge somewhat, but this should have negligible effect on weather here, as it will continue decaying and moving west. The ridge will remain in place today, portending a fairly persistent forecast. As yesterday's front permeates the higher terrain, temperatures down south will cool a little, while temperatures in the north recover a little. Sunday, the ridge intensifies a bit, increasing thicknesses and yielding highs 2-3 F warmer than today's.
1227 AM CDT Sat Aug 10 2024 (Now Thru Saturday) A cold front is slowly sinking south across the region today, leading to a well-below average day temp wise with lower humidity. The high based activity to our west has faded as it typically does during this time of the day so the plan is to start the night with no PoPs.
(Today through Sunday) Upper level low over the Great Lakes Region has absorbed Debby over the NE CONUS (finally) and will continue to slowly meander over the weekend to the south and east towards upstate NY.
(Now through Sunday) A weak mid level flow pattern will remain in place across our forecast area through the weekend as our region remains located to the south of an upper level trough over the Great Lakes and to the east of a broad upper level ridge of high pressure that will stretch from the southern Plains to the Lower Mississippi Valley region. The highest heat index values between 105-110 degrees will be located along much of the western FL panhandle today where another Heat Advisory will be in effect from 11 AM to 7 PM.
247 AM PDT Sat Aug 10 2024 Strengthening high pressure aloft and increasing monsoonal moisture will bring a hotter weather inland today, with a chance of thunderstorms over the mountains and portions of the deserts. Cooler with continued chances of thunderstorms over the mountains and deserts on Sunday.
441 AM CDT Sat Aug 10 2024 (Today through Sunday afternoon) WV imagery this morning shows the upper ridge covering the southwest and central CONUS, extending from the eastern Pacific to the ArklaTex and into the Gulf of Mexico. The old inverted trough is now over Baja, bifurcating the ridge somewhat, but this should have negligible effect on weather here, as it will continue decaying and moving west. The ridge will remain in place today, portending a fairly persistent forecast. As yesterday's front permeates the higher terrain, temperatures down south will cool a little, while temperatures in the north recover a little. Sunday, the ridge intensifies a bit, increasing thicknesses and yielding highs 2-3 F warmer than today's.
647 AM CDT Sat Aug 10 2024 (Today through Sunday Night) The Natural State rmns under the influence of high pressure that was centered over the Central Plains. An upper low wl meander north of the Great Lakes, while a flat upper ridge axis stays in place over TX and the southwestern U.
50" for the lower elevations according to satellite estimates. The ridge has shifted east into Texas with a weak low over Baja California up into SW Arizona. With this pattern in place today, we expect the higher storm chances to be north and west of the Flagstaff area in western Yavapai & Coconino counties, with only a slight 10-20% chance in the White Mountains.
Warm and muggy conditions will continue today, with afternoon highs in the low to mid 90s. The western Atlantic ridge axis lifts across south Florida this weekend promoting south to southwest winds around 8-12 kts.
620 AM EDT Sat Aug 10 2024 - Breezy and cooler today with westerly wind gusts around 30 mph. Cooler conditions entrenched across the region will offer a favorable background environment for a broad increase in VFR diurnal cumulus, leaning to a window for coverage to become broken. Some perpetuation of a higher based VFR cloud plausible beyond sunset, as pockets of moisture rotate through an existing mid level trough. Large upper level low/trough encompassing Central Canada south into the Midwest/Great Lakes region, with at least 3 distinct upper level waves/mid level cold pools rotating around.
Based on satellite and radar trends, this trough is tracking farther south than most guidance.
620 AM CDT Sat Aug 10 2024 (Today through Sunday) Key Messages: - Heat Advisory in effect for the Coastal Bend - Moderate to major risk of heat-related impacts this weekend Water vapor imagery this morning reveals an upper level ridge in place across the Southern Plains and an upper trough moving across the Great Lakes. Upper level ridging remains in control on Sunday. Feel confident in the low risk today but will need to monitor the coast through the day in case we need to bump up to a moderate risk.
As the high cloud cover moves out, this reveals the lingering low cloud deck over the High Plains. Expect daily chances for showers and thunderstorms as several pieces of energy continue to emanate from the slow moving parent trough in the Pacific Northwest. Areas of fog and/or low-level stratus persist early this morning across the high plains along & east of the Laramie Range, giving way to pockets of MVFR to IFR ceilings & visibilities.
_____________________________________________________________ Broad surface ridging sliding up the the Ohio River Valley will result in dry conditions today with some diurnal cu development as convective temperatures are met this afternoon. Highs will top out slightly below normal as an upper trough moves over SE Canada with weak cold advection, and a very comfortable mid-August day is in store. __________________________________________________________ Mostly dry weather will continue with the mentioned high pressure largely in control. Temperatures will run a couple degrees below average underneath the troughing pattern.
(Rest of Today) Surface analysis this morning shows high pressure well in control and centered to the west over the Central Plains. The cold front from yesterday is now stalled along the Atlantic Coast. On top of the "cooler" temperatures, dew points will only be in the low/mid 60s, making those max temps this afternoon very tolerable.
626 AM CDT Sat Aug 10 2024 (Today through Sunday) Big picture wise, in the upper levels we have a fairly strong low centered over southeast Canada just north of the Great Lakes with a shallow trough over the upper midwest into the Ohio Valley. The remnants of Debby are pretty well gone being absorbed into the front over New England associated with the low. Over the southwest is a and extending across the southern US and down into the Mexico and the Gulf of Mexico is a dome of high pressure. 5 range and Td in the low to mid 70s are indicative of the overall dry atmosphere. While the high pressure will push temperatures into the upper 90s, the lower humidities will keep the apparent temperatures in the low 100s below the threshold for heat headlines.
* Very pleasant weekend with cooler temperatures and lower humidity. Below normal temperatures and dry weather will continue into the second half of the weekend as an upper level trough will remain over the eastern one-third of North America. With the center of high pressure still slightly NW of the area on Sunday, light NW flow in the low-levels and a lack of significant height increases will keep temperatures fairly similar to Saturday, possibly adding 1 to 2 degrees as CAA wanes.
555 AM CDT Sat Aug 10 2024 (Today through Sunday) The Subtropical Ridge remains nearly overhead in the short term.
1007 AM EDT Sat Aug 10 2024 * Very pleasant weekend with cooler temperatures and lower humidity. These conditions will continue as high pressure is overhead. Dew points will remain in the low 60s through the day and high temperatures will reach the upper 70s and low 80s in the afternoon (still below normal). Below normal temperatures and dry weather will continue into the second half of the weekend as an upper level trough will remain over the eastern one-third of North America. With the center of high pressure still slightly NW of the area on Sunday, light NW flow in the low-levels and a lack of significant height increases will keep temperatures fairly similar to Saturday, possibly adding 1 to 2 degrees as CAA wanes.
516 AM CDT Sat Aug 10 2024 (Today through Sunday Night) Today is National Lazy Day, which works out perfectly because today will be a fantastic day to stay curled up indoors in the AC and out of the heat! Ridging aloft continues to prevail with mid level high pressure continuing to sit overhead. We'll have slightly warmer 850mb temperatures (increasing from 19- 21Â°C on Saturday to 20-22Â°C on Sunday) and slightly drier air. It'll allow for a few spots in the Piney Woods to drop into the low 70s overnight, but the rest of us will be stuck with lows in the upper 70s to low 80s.
629 AM CDT Sat Aug 10 2024 (Today through Sunday) Cooler temps and beautiful weather is in store for this weekend, with dewpoints in the 50s it will feel much cooler outdoors. High temps look to be in the low to mid 80s both for today and Sunday, with very low chances for rain. Northerly winds around 5 to 10 mph with some higher gusts may help low level mixing and bring dewpoints down a few more degrees, but the cooler northerly flow should keep high temps in the 80s through the weekend despite the drier air mixing down to the surface.
Low temperatures tonight will range from the lower 70s in the Hill Country to the lower 80s along the Rio Grande. On Sunday, mid and upper level high pressure will likely result in dry weather along with temperatures at or just above climatological normals for this time of year.
1157 AM CDT Sat Aug 10 2024 (Today through Sunday afternoon) WV imagery this morning shows the upper ridge covering the southwest and central CONUS, extending from the eastern Pacific to the ArklaTex and into the Gulf of Mexico. The old inverted trough is now over Baja, bifurcating the ridge somewhat, but this should have negligible effect on weather here, as it will continue decaying and moving west. The ridge will remain in place today, portending a fairly persistent forecast. As yesterday's front permeates the higher terrain, temperatures down south will cool a little, while temperatures in the north recover a little. Sunday, the ridge intensifies a bit, increasing thicknesses and yielding highs 2-3 F warmer than today's.
Mid level ridging will generally remain in control of the weather through Sunday with the bulk of any additional convection tonight remaining to our north.
217 PM MDT Sat Aug 10 2024 Satellite imagery shows a low amplitude ridge axis through central MT while a Pacific NW trough was moving into the northern Rockies. Sunday will be cooler with highs ranging from the lower 70s east to lower 80s west.
1258 PM CDT Sat Aug 10 2024 (Today through Sunday Night) Today is National Lazy Day, which works out perfectly because today will be a fantastic day to stay curled up indoors in the AC and out of the heat! Ridging aloft continues to prevail with mid level high pressure continuing to sit overhead. We'll have slightly warmer 850mb temperatures (increasing from 19- 21Â°C on Saturday to 20-22Â°C on Sunday) and slightly drier air. It'll allow for a few spots in the Piney Woods to drop into the low 70s overnight, but the rest of us will be stuck with lows in the upper 70s to low 80s.
(This evening through Sunday) We can now wave goodbye to those slightly cooler temperatures we had today as the upper-level ridge begins to build back across West Central Texas, bringing more hot and dry conditions back to the area.
1227 PM CDT Sat Aug 10 2024 (Today through Sunday) Big picture wise, in the upper levels we have a fairly strong low centered over southeast Canada just north of the Great Lakes with a shallow trough over the upper midwest into the Ohio Valley. The remnants of Debby are pretty well gone being absorbed into the front over New England associated with the low. Over the southwest is a and extending across the southern US and down into the Mexico and the Gulf of Mexico is a dome of high pressure. 5 range and Td in the low to mid 70s are indicative of the overall dry atmosphere. While the high pressure will push temperatures into the upper 90s, the lower humidities will keep the apparent temperatures in the low 100s below the threshold for heat headlines.
SCT-BKN VFR cumulus this afternoon is being supported by the cooler air associated with troughing over the Great Lakes. Gusts subside after sunset with some degree of clouds holding through the overnight with the trough overhead. It remains possible for a stray shower towards MBS, but will keep mention out given the low probability. Large upper level low/trough encompassing Central Canada south into the Midwest/Great Lakes region, with at least 3 distinct upper level waves/mid level cold pools rotating around.
245 PM CDT Sat Aug 10 2024 - Temperatures will remain below average through the weekend, with lows tonight in the lower 40s to lower 50s and High Sunday in the 70s except for mid to upper 60s southwest.
The dry conditions will favor cooler than normal temperatures tonight with lows falling into the 60s, with low 60s in northern areas.
High pressure over Texas has nosed into east-central and southeast Arizona this morning. Storm motion will be in a circular pattern across northern Arizona as we are on the western edge of the high pressure. 50" for the lower elevations according to satellite estimates. The ridge has shifted east into Texas with a weak low over Baja California up into SW Arizona. With this pattern in place today, we expect the higher storm chances to be north and west of the Flagstaff area in western Yavapai & Coconino counties, with only a slight 10-20% chance in the White Mountains.
The main threat during this period will be some locally heavy rainers, and flash flooding over the higher terrain, along with mud and rock slides in the mtns, will be a concern. Max temps tomorrow will continue to increase, and we should see temps about 3 to 6 degrees warmer than today.
242 PM EDT Sat Aug 10 2024 High pressure will cover the Tennessee Valley and much of the Mid Atlantic states tonight through Sunday while a front drifts from eastern Virginia to the Carolina coast.
The frontal boundary will likely hang around the far southern portions of the forecast area until the upper low across the NE state pushes further east.
(Tonight through Sunday night) Key Messages: - Heat Advisory in effect for the Coastal Bend - Moderate to major risk of heat-related impacts this weekend Not much change to the forecast as a hot and humid weather pattern continues across South Texas due to the influence of a persistent subtropical ridge. Temperatures today and tomorrow will range in the mid-90s along the coast to the low 100s inland. Tomorrow is less likely to need a Heat Advisory as slightly cooler dew points and surface temperatures are expected as the mid-level ridge flattens out.
859 AM PDT Sat Aug 10 2024 Strengthening high pressure aloft and increasing monsoonal moisture will bring a hotter weather inland today, with a chance of thunderstorms over the mountains and portions of the deserts. Cooler with continued chances of thunderstorms over the mountains and deserts on Sunday.
(This afternoon through Sunday) A large but flattened ridge extends across much of the southern half of the CONUS while a broad upper-level low is centered over Ontario. Overall, conditions will be seasonably pleasant for the next couple of days as the ridge maintains control across the region.
Today's weather is being brought to us by an upper high centered over SE New Mexico and Texas, and a weak upper low floating over Baja California.
