256 AM EDT Tue Aug 3 2021 High pressure ridging from the Midwest to New England will provide us with dry weather and gentle breezes coming in from the northeast today and tonight. Smoke aloft concentrations should be fairly light today, with the highest amounts south of I-64, and steadily diminishing over the course of the day. this afternoon will feel similar to yesterday afternoon with high temperatures in the lower and middle 80s and dew points in the 50s. The period will start out with continued meridional flow over the OH Valley with highly amplified west coast ridging and east coast troughing.
High pressure stays directly overhead keeping winds light and variable through mid-morning. The result will be continued cooler than normal temperatures and dry weather for the remainder of the day given the dry and stable airmass.
Near the end of the work week, temperatures become warmer and a slight chance of showers and storms is also possible. High pressure over the region and dry conditions are expected through this period. Temperatures will remain in the low 50s in some valley locations and across the northern portion of the Finger Lakes Region. Temperatures should be a little bit warmer tomorrow as mid to upper 70s will be common across the region. Overnight lows will also be warmer as mid to upper 50s are expected.
-More showers/thunderstorms east than west today -Decreasing precipitation chances tonight We will remain near the axis of the eastern US longwave upper trough through the period.
However, despite the ample sunshine, the region will remain under the influence of a broad mid/upper-level trough. High temperatures this afternoon will run around 5 to 10 degrees below normal for early August, with most locations peaking in the low to mid 80s.
132 AM CDT Tue Aug 3 2021 An upper level ridge will remain centered over Las Vegas today with a plume of monsoon moisture wrapping around the eastern side of the ridge. A weak short wave rotating around the ridge will aid in the development of scattered thunderstorms off the higher terrain of central and eastern New Mexico.
(06Z TAFS) Region will remain on east side of upper ridge.
Water vapor satellite imagery, heights, and lightning shower a ridge over the Rockies at 500mb and a closed low near James Bay in Canada. deep mid-level moisture extended from Mexico through the Rockies and across the Gulf Coast, in addition to a large area around the closed low in Canada. Lightning was noted with various clusters of storms and along the cold front in Canada. 850mb temperatures increase from 12 deg C Monday to 15 deg C today, thus should see temperatures a touch warmer today with most readings 78 to 85 with hazy conditions.
210 AM MDT Tue Aug 3 2021 Narrow band of Monsoonal moisture will move slowly through central and eastern portions of southern Montana today through tonight, pushed along by a slow moving upper trof. Moisture tapers off overnight with ridging trying to re-establish itself along with stronger zonal downslope winds drying out the atmosphere.
308 AM EDT Tue Aug 3 2021 High pressure with mild temperatures and dry conditions are expected through the middle of the week. Near the end of the work week, temperatures become warmer and a slight chance of showers and storms is also possible. High pressure will remain over the region today and tomorrow.
331 AM CDT Tue Aug 3 2021 Northwest flow aloft remains in place across the Plains with ridging over the Desert Southwest. At the surface, large area of high pressure extends from the eastern Great Lakes, through the Ohio Valley and into Eastern KS/Eastern NE.
A northwest flow and drying trend will spread into the area for tomorrow as the ridge re-builds to the west.
850 AM EDT Tue Aug 3 2021 Expect mainly dry weather today as high pressure moves east across the Great Lakes. Showers and thunderstorms will be possible on Wednesday as humidity increases near a trough of low pressure.
High temperatures will trend up with excessive heat expected across the lower deserts west of Tucson today and from Tucson west and north on Wednesday. Cooler temperatures will accompany this upswing in thunderstorm activity this weekend.
941 AM EDT Tue Aug 3 2021 High pressure with mild temperatures and dry conditions are expected through the middle of the week. Near the end of the work week, temperatures become warmer and a slight chance of showers and storms is also possible. High pressure will remain over the region today and tomorrow.
While the pattern will begin to shift slightly after today, these conditions will generally persist into Wednesday as well, albeit with afternoon temperatures perhaps 1 to 3 degrees warmer.
457 AM MDT Tue Aug 3 2021 The upper ridge over the western CONUS is expected to remain for much of this week, but begins to break down a bit by Tuesday as the upper trough deepens over the eastern CONUS. With the overall pattern not changing too much over the week, western CONUS ridging continues to keep our temperatures warm and the ground mostly dry, with highs in the 90s all week long through the most of the forecast area, and mid 80s over the black hills.
2) Plenty of clouds and scattered/broken areas of showers and afternoon storms will keep temperatures cooler. Discussion: An upper trough across the Ohio/Tennessee valleys will remain today with a jet streak over the southern Appalachian producing upper divergence. The upper dynamics and surface convergence along the trough will produce scattered convection throughout the day.

High pressure will remain across northern sections of the U. Temperatures will remain below normal with highs in the low to mid 80s. Temperatures tonight will remain below normal with lows Wednesday morning in the low to mid 60s.
534 AM EDT Tue Aug 3 2021 A plume of deep tropical moisture will remain along and just east of the Carolina and Mid Atlantic Coast through the rest of this week, while an upper level trough slides slowly east across the Commonwealth and weakens.
Have the highest confidence at KLVS, although thunderstorms may impact the TAF site for several hours. High pressure centered over Las Vegas, NV will remain stationary through Wednesday. A short wave trough though is on the east side of the high, drifting slowly south to southeast. This trough will destabilize the atmosphere further over NM and combine with existing moisture to produce showers and thunderstorms with torrential rain. The upper low will slowly move out of NM Wednesday as high pressure builds in behind it.
a strengthening upper ridge centered over Utah and an upper level trough moving east into the Mid Atlantic states will allow the monsoonal moisture axis to drift east across the area during the day and out of the area during the night. High temperatures are expected to be in the low to mid 80s in far eastern Colorado with mid 80 to low 90s elsewhere, warmest across the eastern forecast area where sunshine will be more abundant.
958 AM EDT Tue Aug 3 2021 A plume of deep tropical moisture will remain along and just east of the Carolina and Mid Atlantic Coast through the rest of this week, while an upper level trough slides slowly east across the Commonwealth and weakens.
Light and variable winds under the high will continue to promote afternoon lake breezes and slightly cooler onshore winds both afternoons. High temperatures today will be a couple of degrees warmer than those observed yesterday, which should put most inland areas at, or a bit above, 80 degrees.
Have included some haze mention again today though with the high more to the east than recent days would expect lesser particulate concentrations than have been seen recently.
A ridge of high pressure will build across the Northern Rockies today and Wednesday, with a considerable warming trend expected.
Convective models only fire stuff along the higher elevations of southeastern KY (Bell/Harlan/Letcher in JKL's area). High pressure ridging from the Midwest to New England will provide us with dry weather and gentle breezes coming in from the northeast today and tonight. Smoke aloft concentrations should be fairly light today, with the highest amounts south of I-64, and steadily diminishing over the course of the day. this afternoon will feel similar to yesterday afternoon with high temperatures in the lower and middle 80s and dew points in the 50s. The period will start out with continued meridional flow over the OH Valley with highly amplified west coast ridging and east coast troughing.
The deterministic GFS/NAM/ECMWF predict a weak upper low over the CWA today, followed by a slow transition to a building upper ridge over the region Wednesday.
620 AM EDT Tue Aug 3 2021 Dry and seasonable over the next couple of days, with warmer and more humid weather developing this weekend.
/Issued 310 AM CDT Tue Aug 3 2021/ An upper level short wave trough is expected to slowly move southeast across Colorado today and then it will move across the Panhandles on Wednesday. Low level moisture will be lacking somewhat across the Panhandles through Wednesday which will limit the amount of rainfall that may have been realized if the low level moisture was present.
548 AM CDT Tue Aug 3 2021 Northwest flow aloft remains in place across the Plains with ridging over the Desert Southwest. At the surface, large area of high pressure extends from the eastern Great Lakes, through the Ohio Valley and into Eastern KS/Eastern NE.
Another day with mostly sunny skies will also bring the upper 80s and low 90s to the area, most likely a 1 to 3 degrees warmer than yesterday. Highs for the end of the week and the weekend will remain in the low to mid 80s, decreasing into the beginning of the work week after the larger system moves through the region.
Monsoon moisture drops south with upper ridging building in across western Wyoming.
However, despite the ample sunshine, the region will remain under the influence of a broad mid/upper-level trough. High temperatures this afternoon will run around 5 to 10 degrees below normal for early August, with most locations peaking in the low to mid 80s. This will bring another reinforcing shot of "cooler" air and some additional cloud cover by Wednesday afternoon, helping to keep highs in the lower 80s once again.
650 AM EDT Tue Aug 3 2021 Expect mainly dry weather today as high pressure moves east across the Great Lakes. Showers and thunderstorms will be possible on Wednesday as humidity increases near a trough of low pressure.
From synopsis, a weak ridge axis extending across South Florida will maintain light to occasionally moderate southeast to south flow over the Florida Keys coastal waters for the next couple of days and near- to or slightly below-normal rain and thunder chances.
331 AM PDT Tue Aug 3 2021 Strong high pressure over the southwest states will continue dangerously hot conditions for inland areas through Wednesday.
A broad upper trof covers the eastern United States with the trof axis near the AL/MS state line. Extensive mid level clouds were present along and east of the trof axis. The upper trof axis will linger across Alabama on Wednesday. Another impulse will push through the base of the trof on Wednesday and trigger scattered showers and a few thunderstorms across east Alabama.
/issued 132 AM CDT Tue Aug 3 2021/ An upper level ridge will remain centered over Las Vegas today with a plume of monsoon moisture wrapping around the eastern side of the ridge. A weak short wave rotating around the ridge will aid in the development of scattered thunderstorms off the higher terrain of central and eastern New Mexico. The steady increase in geopotential heights heading into this weekend will result in temperatures rising into the middle-upper 90s area-wide, to perhaps the triple-digits across the low Rolling Plains.
/Issued 318 AM EDT Tue Aug 3 2021/ 500mb analysis shows a broad trough digging across the eastern part of the country.
Instability, albeit on the low side, is supportive of thunder inclusion so added that as well.
High temps will be reaching the lower 90s and for areas with early rain activity, these might stay in the upper 80s.
A ridging pattern remains aloft over the western United States and there is a trough to the east. Besides the haze, skies will be sunny with seasonal highs in the low 90s. There should be a slight increase in moisture ahead of the trough with dew points rising to the upper 50s to low 60s. The trough will bring somewhat cooler air to the area, leading to highs in the 80s.
High temperatures trend warmer today and Wednesday as high pressure slowly builds over NV.
(Issued 335 AM CDT Tue Aug 3 2021) Today through Wednesday: We'll remain between an upper level trough to our east and an upper level ridge to our west over the next few days. This will keep high pressure and comfortable conditions over our area which you can't beat for this time of year. Wednesday should be a rinse and repeat of today with highs approaching the low 80s which is normal for this time of year.
An increase in cloud cover is likely Wednesday evening across western MN as a weak cold front approaches from the Dakotas. Ridging in the mid levels will shift east late Wednesday as a short wave approaches from the Dakotas.
911 AM CDT Tue Aug 3 2021 After a rather cool morning with lows in the lower to middle 60s, temperatures are now warming slowly into the upper 60s to middle 70s. A few showers or thunderstorms could develop late this afternoon in the eastern Plateau areas, aided by convergence along an inverted trough near or just east of the AL/GA state line. This may be aided by a weak impulse dropping southeast through the upper trough across the eastern CONUS. This will bring another reinforcing shot of "cooler" air and some additional cloud cover by Wednesday afternoon, helping to keep highs in the lower 80s once again.
Broad upper trough continues to dig southward this morning over the eastern US, and will help keep us a bit cooler with highs in the 80s for the next few days. By this afternoon, the trough axis will be to our west, and some isolated showers and storms may develop on the Plateau, otherwise dry conditions will continue for the rest of the mid state.
Have kept temperatures on the slightly cooler side of the 50th percentile to account for this, but that still leaves rather pleasant afternoon temperatures in the 80s. By Wednesday morning, the ridge aloft will have flattened as an elongated vorticity maximum moves through western South Dakota.
Temperatures will continue to run above normal through Wednesday across the area due to a strong ridge of high pressure aloft.
320 AM MDT Tue Aug 3 2021 The upper ridge over the western CONUS is expected to remain for much of this week, but begins to break down a bit by Tuesday as the upper trough deepens over the eastern CONUS. With the overall pattern not changing too much over the week, western CONUS ridging continues to keep our temperatures warm and the ground mostly dry, with highs in the 90s all week long through the most of the forecast area, and mid 80s over the black hills.
655 AM EDT Tue Aug 3 2021 A plume of deep tropical moisture will remain along and just east of the Carolina and Mid Atlantic Coast through the rest of this week, while an upper level trough slides slowly east across the Commonwealth and weakens.
and maybe just a few deg warmer for Wed afternoon. where highs will be in the low 80s to around 90.
A building upper ridge should bring mainly dry conditions tonight into Wednesday.
High pressure ridging from the Midwest to New England will provide us with dry weather and gentle breezes coming in from the northeast today and tonight. Smoke aloft concentrations should be fairly light today, with the highest amounts south of I-64, and steadily diminishing over the course of the day. this afternoon will feel similar to yesterday afternoon with high temperatures in the lower and middle 80s and dew points in the 50s. The period will start out with continued meridional flow over the OH Valley with highly amplified west coast ridging and east coast troughing.
642 AM EDT Tue Aug 3 2021 High pressure with mild temperatures and dry conditions are expected through the middle of the week. Near the end of the work week, temperatures become warmer and a slight chance of showers and storms is also possible. High pressure will remain over the region today and tomorrow.
After a rather cool morning with lows in the lower to middle 60s, temperatures are now warming slowly into the upper 60s to middle 70s. A few showers or thunderstorms could develop late this afternoon in the eastern Plateau areas, aided by convergence along an inverted trough near or just east of the AL/GA state line. This may be aided by a weak impulse dropping southeast through the upper trough across the eastern CONUS. This will bring another reinforcing shot of "cooler" air and some additional cloud cover by Wednesday afternoon, helping to keep highs in the lower 80s once again.
The lee trough will be slightly deeper today, so as a result, slightly stronger southerly winds of 10 to 20 mph will prevail throughout the daylight hours. Convection looks to still develop on the higher terrain of Colorado. Dewpoints are expected to run in the lower 50s by morning. On Wednesday, a weak warm front/trof axis will bisect the FA. Will continue with the highest pops across the far western zones Wednesday evening.
148 PM EDT Tue Aug 3 2021 High pressure with mild temperatures and dry conditions are expected through the middle of the week. Near the end of the work week, temperatures become warmer and a slight chance of showers and storms is also possible. High pressure will remain over the region today and tomorrow.
Temperatures will cool into the lower 60s for most areas. Otherwise, expect a mostly sunny sky and highs in the lower to middle 80s.
At the surface, a trough stretches over our region, with high pressure pushing in from the west.
330 PM EDT Tue Aug 3 2021 Latest analysis shows an upper level trough across the area with one short wave moving across the area this afternoon into tonight, and another wave is expected to move across the area Wednesday into Wednesday night. At the surface, a stationary front remains over the SE and deep south states, with multiple areas of low pressure along the front. Areas of high pressure continue to our N/NW.
Our pattern with the trough to our east and the ridge to our west will hold steady over the next few days with E to SE flow. Dry air in the low and mid levels will result in all but nil precipitation chances for the entire region Tuesday and Tuesday evening. Some clearing overnight in the Permian Basin will help us cool down into the low to mid 60s Wednesday morning.
Afternoon temperatures were in the upper 70s to the lower 80s. The typical cool spots will see lows in the mid-upper 50s with the urban corridors remaining in the lower 60s. Inverted trough axis across eastern KY may result in some scattered afternoon/evening showers and thunderstorms. Highs on the day will top out again in the upper 70s to the lower 80s. Wednesday night, upper flow becomes more progressive and moves a mid- level trough, that brought earlier rain showers to the CWA, off to the east.
Some of the high-resolution models suggest that isolated showers/storms could also develop to the northeast and sneak in to our area. Tomorrow's high temperatures will be a few degrees warmer than today with values in the upper 80s to mid 90s and light east winds.
High temperatures will trend up with excessive heat expected across the lower deserts west of Tucson today and from Tucson west and north on Wednesday. Cooler temperatures will accompany this upswing in thunderstorm activity this weekend. Heat remains the primary concern for today and tomorrow as a strong ridge sets up over the Desert Southwest.
Overall, the visibilities should remain on the high end of MVFR, although the potential for further localized reductions will exist overnight similar to what FYV saw last night.
Showers and thunderstorms are expected to develop over the higher terrain of CO and NM later this afternoon and tonight, with some of the showers and storms possibly moving into the far western and northwestern counties through tonight.
For tomorrow afternoon, mid-level ridging builds in from the west and as a result temperatures will be slightly higher than today by a degree or two.
1242 PM CDT Tue Aug 3 2021 Reduced visibilities due to smoke persist, although the lowest readings in the forecast area at the moment are six miles in a few locations.
327 PM EDT Tue Aug 3 2021 Mississippi Valley Upper trough slowly but steadily de-amplifies and lifts northeast through the short-term forecast period. Region remains in line to see some influence from short waves moving through the flow ahead of the trough. Moisture somewhat limited as the original frontal boundary associated with this trough remains suppressed into south Georgia by surface ridging down the east side of the Appalachians.
Surface pressure gradient on Wednesday will tighten in advance of an approaching trough, allowing southerly winds to increase somewhat with some afternoon gusts up to 25 mph. perhaps a degree or two warmer, especially west of the I-29 corridor.
Dry weather is expected through the short term period with a continued pattern of troughing across much of the Midwestern States and ridging across the West. Could see afternoon temperatures a degree or two higher compared to today as the upper level trough finally begins to lose its hold on the region but not expecting any significant weather pattern changes until later this week. Expect highs in the low 80s tomorrow with lows dropping into the upper 50s to low 60s tomorrow night as surface dew points gradually creep higher due to the loss of northerly to northeasterly flow.
An upper level trough will contribute to much cooler temperatures than normal today and tomorrow. The highest totals will be located east of the forecast area.
Afternoon temperatures will generally be in the lower to middle 80s. Looking at CAMs models for precipitation it really doesn/t look like the trough retrogrades westward that much today so the POPs for the Plateau may not happen.
Light and variable winds under the high will continue to promote afternoon lake breezes and slightly cooler onshore winds both afternoons. High temperatures today will be a couple of degrees warmer than those observed yesterday, which should put most inland areas at, or a bit above, 80 degrees. KJB 225 PM CDT The high pressure will move southeast of the area by the start of the forecast period, with return flow starting to pump warm, moist air into our region.
High pressure and light winds are keeping smoke and haze trapped across the region. and maybe just a few deg warmer for Wed afternoon. where highs will be in the low 80s to around 90.
Some of the high-resolution models suggest that isolated showers/storms could also develop to the northeast and sneak in to our area. Tomorrow's high temperatures will be a few degrees warmer than today with values in the upper 80s to mid 90s and light east winds. /Issued 256 AM CDT Tue Aug 3 2021/ /Wednesday Onward/ Through the middle and end of this week, North Texas will remain positioned between upper troughing to the east and an amplified ridge to the west, allowing weak northwesterly flow aloft to persist. Meanwhile, southerly flow will resume through the low levels while the remnant frontal zone lifts back northward.
The high will gradually work its way off to our southeast with another lake breeze day looking likely for Wednesday.
