340 PM EDT Thu Oct 3 2024 Weak high pressure will be in place through tonight, and then push slowly offshore Friday.
Highs will be quite a bit cooler today with steady 10 to 15 mph northwest winds. The zonal pattern in place today will change to subtle 500mb ridging by Friday.
Overnight lows will be a bit warmer compared to last night.
While high pressure will keep light winds and clear skies in the forecast for today, a trough of low pressure will dig southward along the West Coast. The low begins to move east through the Pacific Northwest on Friday morning. This system, along with an associated strong cold front, will enter the Northern Rockies by Friday afternoon. High winds will favor the higher terrain, especially along the Continental Divide, where there will be about a 60-70 percent chance for gusts to exceed 50 mph. The lower elevations will also see formidable winds. Chances for precipitation will accompany the cold front, though rain amounts will mostly stay below about 0.
Moisture will continue to filter in as its guided by a trough in the western Caribbean. As this low meanders northeast, rounds of deep tropical convection (with lulls included to recharge the atmosphere) are expected to stream over the Florida Keys and its surrounding waters.
Rain chances will diminish significantly by Friday evening/night as the boundary sags back to the south and high pressure builds back in from the north.
Afternoon temperatures will be warmer. The thermal trough will move inland but will continue to produce strong north winds through this evening.
As a ridge of high pressure builds back over Southern California, the marine layer is expected to become shallower and staying confined to the coast over the weekend. Temperatures at 1 PM this afternoon were running 3 to 7 degrees cooler than 1 PM yesterday.
1228 PM CDT Thu Oct 3 2024 (Today through Friday Night) Dry conditions will persist across the state through the short term portion of the forecast (and beyond) as ridging aloft and at the sfc remain over the region. Temperatures are expected to be warmer than yesterday across the state with Td values bottoming out in the 40s/50s F by this afternoon. Normal highs for early October range from the mid 70s F to the lower 80s F which means daytime highs will be about 10-15 degrees above normal by Friday.
340 PM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
Upper level ridging will continue to expand across the Desert Southwest into portions of the southeastern region through the period which will help keep weather conditions at bay. We will begin to see a slight reprieve from temperatures overnight into tomorrow as the upper level trough translating across northern CONUS pushes a weak cold front through the FA tonight into early tomorrow morning. Post frontal winds will shift out of the north, bringing in a much cooler air mass with overnight lows a few degrees cooler on the Caprock in the upper 40s to upper 50s. Expect a pleasant Friday with daytime highs ranging from the lower 80s across our northwest counties into the lower 90s across our southeastern counties.
1218 PM CDT Thu Oct 3 2024 (Today and tonight) The forecast area will remain underneath a weak mid/upper level trough that is wedged between upper ridging over the desert southwest and the southeastern CONUS. The ridge to the west will begin to expand eastward tonight as a fast-moving trough in the northern stream treks from the Dakotas to the western Great Lakes. This trough will also push a weak cold front into, and possibly through, the forecast area by sunrise Friday and will result in cooler overnight lows, especially across the northwestern third to half of the forecast area.
132 PM EDT Thu Oct 3 2024 Fog this morning, then a dry Thursday under high pressure. Any activity is likely to subside after sundown, then high pressure and weak upper ridging allow for a quiet start to the weekend. Temperatures should hover above normal through the end of the week, with highs ranging from mid 70s to low 80s in the lowlands and mid 60s to upper 70s for the mountains.
1111 AM MDT Thu Oct 3 2024 - A respite in fire weather conditions for Thursday as a cold front sags into the area from the north.
Light winds and warm temperatures will continue today as the ridge of high pressure continues to build into the region. The dry cold front is still anticipated to move in later on Friday evening, with southwest winds sustained at around 20-30 mph with gusts to 30-40 mph across most of the region except for the Treasure Valley.
Main impact in the short term will be the significant wind increase on Friday as a cold front moves through eastern Idaho which will instigate the wind increase. will see much warmer conditions again Friday with highs well into the 80s in low elevations and 60s and 70s mountains.
313 PM CDT Thu Oct 3 2024 - A cold front will trigger scattered showers and a few thunderstorms late tonight into Friday morning. Currently, a cold front stretches southwestward from a Canadian low through SE Wisconsin, to near the SE corner of Colorado, with a weak low migrating northeastward along the front near NE KS.
High pressure has started to weaken across the area this afternoon as an upper level trough approaches the Pacific Northwest. Temperatures in many of the inland areas are running a few degrees cooler than yesterday. Friday this trough moves onshore in the afternoon. This will bring temperatures 5 to 10 degrees cooler. The low levels remain very dry so it is unlikely anything more than a sprinkle or two will make it to the ground. This trough will bring some increased west to northwest winds around midday and into the afternoon. H850 MB winds of 15 to 25 mph are expected and some of these may mix down, especially over the higher terrain of the inland areas.
929 PM CDT Thu Oct 3 2024 - A cold front will trigger scattered showers and a few thunderstorms late tonight into Friday morning. Current forecast has temps falling into the lower to middle 50s overnight and this still looks like a good forecast. Auten Currently, a cold front stretches southwestward from a Canadian low through SE Wisconsin, to near the SE corner of Colorado, with a weak low migrating northeastward along the front near NE KS.
Over eastern AR and the MO bootheel, 9 PM temps were 3-5 degrees warmer than 24 hours ago. Dewpoints across the Midsouth were similarly warmer than 24 hours ago.
Due to both clouds and higher dewpoints, lows will be a few degrees warmer (compared to last night) and generally in the l-m 60s.
738 PM EDT Thu Oct 3 2024 Weak high pressure will be in place through tonight, and then push slowly offshore Friday.
954 PM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
646 PM CDT Thu Oct 3 2024 - A cold front will trigger scattered showers and a few thunderstorms late tonight into Friday morning. Currently, a cold front stretches southwestward from a Canadian low through SE Wisconsin, to near the SE corner of Colorado, with a weak low migrating northeastward along the front near NE KS.
- Frost Advisory for a few northwestern counties tonight into Friday morning (freezing temperatures unlikely, however).
Tomorrow should be a bit cooler to compensate thanks to cloud cover, with highs in the upper 70s and lower 80s in all but east central Georgia, where the mid 80s could be achieved.
805 PM EDT Thu Oct 3 2024 Dry high pressure moves off the East Coast tonight before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms to the mountains. Drier conditions return over the weekend as high pressure builds back into the region.
556 PM MDT Thu Oct 3 2024 - Cold temperatures around freezing are briefly expected tonight across the San Luis Valley, with a Frost Advisory now in effect.
1052 PM EDT Thu Oct 3 2024 Weak high pressure will be in place through tonight, and then push slowly offshore Friday.
816 PM EDT Thu Oct 3 2024 An upper ridge across the southeast today will gradually shift to the east and south overnight into Friday.
By the afternoon a weak trough will develop across the northwest ahead of a front that will remain north of us.
623 PM CDT Thu Oct 3 2024 (This evening through Friday Night) Leading edge of a elongated coastal trof stretching from the Bay of Campeche to the wcntl LA waters will continue to slowly track westward and a bit further into the TX coastal waters tonight into the weekend.
730 PM EDT Thu Oct 3 2024 High pressure will build across the region and allow for dry weather through the end of the week.
929 PM CDT Thu Oct 3 2024 - A few light showers tonight with a cold front.
A large area of high pressure extends from the eastern Pacific to the Desert Southwest region.
600 PM CDT Thu Oct 3 2024 (Tonight through Friday night) Water vapor imagery shows an upper low over north-central Mexico, with ridging over much of central and north Texas. Look for lows to drop into the lower 60s to near 70 degrees.
However, weak upper ridging over the southern Atlantic states will give way to a broad upper trough axis traversing eastward across the TN/OH Valley areas. Weak synoptic lift associated with the upper trough axis may allow for a low chc (20%) of showers/tstms along/east of the I-65 corridor this afternoon. Otherwise, look for another seasonably warm day for the mid TN Valley, as highs climb mainly into the lower/mid 80s for most spots.
Upper level ridge axis will shift offshore today with high pressure at the surface continuing over the area.
142 AM EDT Fri Oct 4 2024 Dry high pressure moves off the East Coast tonight before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms to the mountains. Drier conditions return over the weekend as high pressure builds back into the region.
Main area of less hot conditions behind the front will be across northwest quarter or so of Oklahoma, where highs today are expected to be around 10 degrees cooler than yesterday (but still above average).
(Today and tonight) Upper level high pressure centered over the Four Corners has begun to expand eastward over the Texas and Oklahoma Panhandles with further expansion southward over the forecast area expected today which will displace the weak upper trough that has been overhead to the south of the region. Despite the increase in mid level geopotential heights, highs today will be cooler than those of yesterday as a modest cold front will be moving through the forecast during the early morning hours today. The cooler temperatures will be most pronounced across the northwestern part of the forecast area with the least effect across the southeast.
Low temperatures will mostly range the mid 70s, falling into the low 70s across rural areas.
Discussion: A weak upper trough will move across the region today along with an approaching boundary. For tonight, trough axis and boundary moves east with weak pressure gradient and mostly clear/partly cloudy sky.
313 AM EDT Fri Oct 4 2024 Slightly above normal temperatures and mainly dry weather are expected to continue through the weekend as high pressure dominates the weather pattern across the Carolinas.
1233 AM CDT Fri Oct 4 2024 - Frost Advisory for a few northwestern counties tonight into Friday morning (freezing temperatures unlikely, however).
256 AM EDT Fri Oct 4 2024 - Frost/freeze conditions possible tonight, mainly across typically cooler/inland locations. This trough axis shifts east of the area this afternoon with slowly rising heights for the night ahead.
340 AM CDT Fri Oct 4 2024 Today and Tonight: Looking aloft, the trailing southern end of an upper-level trough axis lies over the Gulf Coast region. A jet streak associated with this trough is centered over Tennessee this morning, and the its right entrance region extends southwest toward the central Gulf Coast.
1149 PM CDT Thu Oct 3 2024 - A cold front will trigger scattered showers and a few thunderstorms late tonight into Friday morning. Current forecast has temps falling into the lower to middle 50s overnight and this still looks like a good forecast. Auten Currently, a cold front stretches southwestward from a Canadian low through SE Wisconsin, to near the SE corner of Colorado, with a weak low migrating northeastward along the front near NE KS.
129 AM EDT Fri Oct 4 2024 Weak high pressure will be in place through tonight, and then push slowly offshore Friday.
A weak cold front will move into the area this morning, becoming diffuse this afternoon.
Patchy dense fog is likely overnight into Friday morning over the higher coastal terrain and on the coastal mesas. An upper level trough moving inland across the Pacific Northwest and the deeper marine layer will help spread some cooling inland, mainly for the mountains westward, while temperatures in the deserts remain similar to today.
212 AM EDT Fri Oct 4 2024 Weak high pressure will extend into the region from the northeast today.
Some drying has taken place since yesterday and will result in overnight lows cooler than they have been, but still close to normal for this time of year. A highly amplified ridge will remain entrenched over the region through the weekend, with temperatures continuing to run about 15 degrees above normal.
1101 PM EDT Thu Oct 3 2024 Dry high pressure moves off the East Coast tonight before a cold front approaches the area on Friday, bringing scattered showers and isolated thunderstorms to the mountains. Drier conditions return over the weekend as high pressure builds back into the region.
High pressure ridging will remain consistent over Central California through the weekend, leading to continued well above normal temperatures for the time of year.
118 AM EDT Fri Oct 4 2024 High pressure will build across the region and allow for dry weather through the end of the week.
239 AM MDT Fri Oct 4 2024 KEY MESSAGES: - High Wind Warning issued as strong but dry cold front brings high W-NW winds.
Instead the waves moving through it are just deforming the large area of high pressure over the mid and lower latitudes of the western CONUS. Today as the next wave moves into the PacNW the high will be nudged out of the Southwest into the S.
There is some cloud coverage over Iowa, Wisconsin, and Illinois that can be attributed to broader troughing over the Great Lakes region. More specifically, temperatures are forecast to be in the mid to upper 70s for places north of I-70, with temperatures peaking in the low to mid 80s for places south of I-70.
223 AM EDT Fri Oct 4 2024 Weak high pressure will extend into the region from the northeast today.
(Today through Saturday night) A very weak front has pushed through AMA this morning and this will lead to slightly cooler highs today across most of the area.
High pressure continues to weaken as an upper-level trough approaches the area. These could result in a sprinkle or two, but the lower levels remain very dry and any rain that does fall is likely to evaporate before reaching the surface. Gustier westerly wind of 25-30 mph is possible this afternoon, especially along the ridges of Lake, Mendocino, and Trinity Counties. Temperatures rebound again this weekend as the trough moves out.
Drier air returns tonight and Saturday, with surface ridging in place across the region. A mid level trough axis will shift to our south, allowing for cloudiness across southern areas. Lows tonight will be in the low to mid 60s, and highs on Saturday in the 80s.
631 AM CDT Fri Oct 4 2024 (Friday through Saturday) The current streak of above average temperatures will continue on through this short-term period as upper-level ridging maintains a presence across much of the SW and SCntrl CONUS. The ridge should win out farther to the north across Cntrl LA and into the rest of our region so have maintained a dry forecast areawide today. High temperatures will range through the lower 90s across the majority of the region, but a few locations may even reach the middle 90s.
Through Saturday ridging to our north will continue with flow mainly from the east and PW hovering around 2.
An upper trough is over the Midwest and an upper ridge extends from Southern California to the southern Plains. An upper trough will be centered over southern Canada on Saturday and will extend southward over Nebraska and northern Kansas. A cold front associated with the trough will move into the area. Clear skies are expected so low temperatures Saturday night will generally range from the lower 40s to mid 50s.
- A cold front will bring chances for showers and isolated thunderstorms Saturday afternoon into Saturday night, but no significant rainfall is expected. High pressure was in control across the Northland early this morning with some high clouds moving across the Borderlands. An upper low will move from southern Saskatchewan into southern Manitoba on Saturday and drag a cold front across the Northland during the afternoon and evening hours. Ahead of the cold front, a narrow ribbon of CAPE around 500 J/kg is forecast to develop which will lead to about a 10% chance for a few thunderstorms.
403 AM CDT Fri Oct 4 2024 (Today through Saturday afternoon) WV imagery this morning shows an upper trough moving through the MS Valley, trailing a weak cold front moving through the Panhandle, w/fropa at KMAF ~ 11Z or so. Saturday, thicknesses come up a bit as an inconsequential inverted trough moves south. Highs will be very similar to today's, if not maybe a degree warmer.
632 AM CDT Fri Oct 4 2024 (Today through Saturday Night) A broad elongated coastal trough over the south central Gulf is ex- pected to gradually strengthen and drift E/NE through this weekend. Lows will run from the upper 60s over the northern counties to the lower to mid 70s elsewhere tonight and to- morrow night.
Temperatures across the island chain are in the lower 80s.
255 AM PDT Fri Oct 4 2024 The coast and valleys will be warmer over the weekend with high temperatures for inland areas remaining around 12 to 18 degrees above average. There will be greater coverage of night and morning coastal low clouds with the low clouds and fog reaching the western valleys late each night.
1059 AM EDT Fri Oct 4 2024 Broad high pressure will remain across the region today.
620 AM EDT Fri Oct 4 2024 Weak high pressure will extend into the region from the northeast today. A cold front will move east across the area late Saturday.
637 AM EDT Fri Oct 4 2024 Slightly above normal temperatures and mainly dry weather are expected to continue through the weekend as high pressure dominates the weather pattern across the Carolinas.
714 AM CDT Fri Oct 4 2024 Today and Tonight: Looking aloft, the trailing southern end of an upper-level trough axis lies over the Gulf Coast region. A jet streak associated with this trough is centered over Tennessee this morning, and the its right entrance region extends southwest toward the central Gulf Coast.
Record warmth is possible again today and Saturday, especially at KJLN (see climate section below for records), with highs ranging from the mid 80s east to the low 90s west of Highway 65.
Rain will likely relax this evening as the upper trough pushes out and the front drifts a little further south putting the rain focus over our coastal waters.
Trough energy approaching the Washington and Oregon coastlines early this morning will move onshore and center over the Pacific NW this afternoon. This evening and overnight the Pacific NW trough will eject east into Idaho and beyond, which will allow high pressure to build in from the south.
(Rest of Today) Dry conditions have persisted this morning as an upper ridge remains centered over the western Atlantic and weak upper troughing shifts east through the Great Lakes. Will be on the warmer side of seasonal norms today, with afternoon highs climbing into the low to mid 80s. Have maintained a low chance (10-20%) for showers and thunderstorms along and east of I-65 where weak convergence associated with the upper trough may generate enough lift to support a few storms.
VAD wind profiler data at DSM reveals a strongly veered low-level wind profile in the lowest 2000 meters, with magnitudes between 40 to 50 knots. Expect more seasonal temperatures today and tonight, with highs in the lower to mid 70s and lows tonight in the 50s.
A strong Pacific cold front, associated with a quickly moving trough of low pressure, will bring the risk of damaging winds and areas of power outages. In most areas, the highest winds will occur along and just behind the frontal passage. The highest gusts will focus along the divide, where peak gusts may approach 65 mph.
610 AM CDT Fri Oct 4 2024 (Today and tonight) Upper level high pressure centered over the Four Corners has begun to expand eastward over the Texas and Oklahoma Panhandles with further expansion southward over the forecast area expected today which will displace the weak upper trough that has been overhead to the south of the region. Despite the increase in mid level geopotential heights, highs today will be cooler than those of yesterday as a modest cold front will be moving through the forecast during the early morning hours today. The cooler temperatures will be most pronounced across the northwestern part of the forecast area with the least effect across the southeast.
531 AM EDT Fri Oct 4 2024 High pressure will remain to our south today. Low pressure will approach tonight then cross the region Saturday.
and Saturday A weak cold front moved across the region last night and managed to produce a hundredth of an inch of rain in a few places despite a very dry atmosphere. Saturday will be breezy and warm, with south winds increasing ahead of a cold front and strong upper level trough.
929 AM CDT Fri Oct 4 2024 - Breezy and warmer Saturday ahead of another front, which will bring a chance of showers and thunderstorms Saturday night.
WV imagery indicates a weak upper level trough of low pressure pushing east out of the Northern Plains into the Upper Midwest. Meanwhile, ridging aloft is shifting east through the Pacific Northwest. Near the surface, a weak cold front is moving slowly southeast into northwest Oklahoma. An ongoing dry pattern will continue through the weekend as the SREF indicates weak ridging aloft shifting east through the Western High Plains today, and on into the Central Plains Saturday. An upper level trough of low pressure is projected to swing through the Northern Plains early in the weekend, sending an attendant cold front into western Kansas by Saturday evening.
There is some cloud coverage over Iowa, Wisconsin, and Illinois that can be attributed to broader troughing over the Great Lakes region. More specifically, temperatures are forecast to be in the mid to upper 70s for places north of I-70, with temperatures peaking in the low to mid 80s for places south of I-70. With a heat dome persisting over the desert southwest due to ridging in the mid to upper-levels, our region's temperatures will be raised for tomorrow. Saturday night, an amplified low pressure centered along the Canada/Minnesota border will lower geopotential heights across the northern tier of the midwest, with no real weather impacts for our area anticipated at this time.
942 AM EDT Fri Oct 4 2024 Weak high pressure will extend into the region from the northeast today. A cold front will move east across the area late Saturday.
(Today through Saturday) An upper level low, noted on GOES 16 water vapor imagery, has settled in over northern Mexico early this morning. Otherwise, the rest of us will likely stay dry and continue with the warmer than normal pattern we've been stuck in for the better part of the past month. We will most certainly take the increased cloud cover and perhaps slightly cooler temperatures, but most of us will miss out on rain.
