1036 PM EDT Thu Aug 24 2017 Currently - A stubborn low level trough remains near South Florida and the Keys this evening, resulting PWAT's above 2 inches. Forecast - The lower level trough will remain near the Keys through the overnight period and tomorrow. A weak trough near South Florida and the Keys will keep mostly light south to southwest winds across Keys waters.
1146 PM CDT Thu Aug 24 2017 A high pressure center over the Great Lakes and rising heights aloft will ensure quiet weather conditions for tonight and tomorrow. Condensation pressure deficit plots show increasing mid/high clouds streaming in from the west late tonight, which should keep overnight lows slightly warmer compared to last night. Winds will become easterly to southeasterly overnight around the southern edge of the Great Lakes high pressure center. The ECMWF suggests the upper low over the Great Lakes associated with precip earlier in the week, remaining in place due to stronger ridging over the ern U. Tilly VFR flight conditions and light easterly flow will continue across the area through Friday evening under the influence of a large high pressure system centered to the northeast.
The end to this work week into the weekend will be a repeat of today with high temperatures in the mid to upper 80s; however, the low temperatures are going to be higher than this morning with values returning to the low to mid 60s which is just shy of seasonal normal values.
High pressure will spread south across the region through the period, with generally dry/quiet conditions expected and with another cool night of below normal temps likely tonight.
Overnight lows are expected to drop into the lower to mid 60s, but may end up a of degrees warmer. Tomorrow will be mostly dry with highs in the lower to mid 80s.
A line of showers and thunderstorms continues north of Baker City-McCall near a cold front.
647 PM CDT Thu Aug 24 2017 A high pressure center over the Great Lakes and rising heights aloft will ensure quiet weather conditions for tonight and tomorrow. Condensation pressure deficit plots show increasing mid/high clouds streaming in from the west late tonight, which should keep overnight lows slightly warmer compared to last night. Winds will become easterly to southeasterly overnight around the southern edge of the Great Lakes high pressure center. The ECMWF suggests the upper low over the Great Lakes associated with precip earlier in the week, remaining in place due to stronger ridging over the ern U.
1026 PM CDT Thu Aug 24 2017 A very large area of high pressure will be situated east of the area tonight, sprawling from the Great Lakes Region southward to the Ohio Valley. 850mb temperatures are actually quite warm Friday afternoon, therefore trended toward the warmer bias corrected readings for highs.
Low level northerly flow has pushed the surface cold front into northwest Florida. Weaker cold air advection on Friday will allow for warmer afternoon temperatures.
Freezing level was near 16,000 feet, the -20C level near 27,500 feet, and the wet bulb zero at 14,600 feet.
1059 PM MDT Thu Aug 24 2017 Current surface analysis shows weak frontal boundary/trough stretching south across the Black Hills area. Upper level analysis shows weakening ridge centered over the northern high plains. Highs will be in the 80s across the plains, with 70s over the higher Black Hills. Winds will switch to the north-northwest from west to east as the trough moves across the area.
1058 PM EDT Thu Aug 24 2017 An large upper level trough over the Great Lakes will provide our region with cool weather through the end of the work week. before high pressure brings dry weather from Friday afternoon right on through the upcoming weekend. A look at satellite imagery this evening reveals quite a bit of cloud cover across the lower Great Lakes, while regional radar showers a cluster of showers gradually making its way southeastward into far southwestern NY.
For Friday through the weekend, high pressure will build in and provide mainly dry and cool weather. Still think a weak lake response will set up over the higher terrain between ITH/UCA/SYR late tonight. Canadian high pressure at the surface will settle over the area this weekend.
842 PM PDT Thu Aug 24 2017 Drying weather pattern and increasing temps are expected going into the weekend as high pressure builds over the Southwest.
717 PM EDT Thu Aug 24 2017 19z sfc analysis shows high pressure over the region. They all agree that the core of the eastern trough through the Great Lakes will shift east and away from the area tonight with heights rebounding and the mid level northwest flow relaxing.
831 PM EDT Thu Aug 24 2017 An large upper level trough over the Great Lakes will provide our region with cool weather through the end of the work week. before high pressure brings dry weather from Friday afternoon right on through the upcoming weekend. A look at satellite imagery this evening reveals quite a bit of cloud cover across the lower Great Lakes, while regional radar showers a cluster of showers gradually making its way southeastward across Lake Erie.
At 900 pm temperatures were in the lower 60s to the lower 70s and dew points in the 50s. Temperatures will drop into the 50s to lower 60s by morning as drier air mass from high pressure over Eastern Canada and the Great Lakes settles farther south into the Tennessee Valley.
19z sfc analysis shows high pressure over the region. They all agree that the core of the eastern trough through the Great Lakes will shift east and away from the area tonight with heights rebounding and the mid level northwest flow relaxing.
Dry conditions and another comfortably cool (for latter August) remains in the forecast, as the high to our north exerts its influence southward. As such, night time lows temperatures should range from the upper 50s in the more sheltered spots, mainly across NE Alabama and adjacent southern middle TN, to the low/mid 60s (the warmest temperatures near and just downwind of large bodies of water). After another seasonably cool morning Sat in the lower/mid 60s, moisture/cloud cover will begin to gradually increase over the mid TN Valley, as the high pressure shifts ewd towards the mid Atlantic Basin and the sfc flow veers to the E/SE during the day Sat.
Temperatures will increase in response to the desiccating airmass and strengthening mid-level anti-cyclone, which will have the heart of the positive height anomalies displaced over the PacNW (though the center of the circulation will be anchored over the Great Basin). Temperatures warm enough to start flirting with the High HeatRisk category Sat/Sun, so we'll be keeping an eye on that.
Water vapor imagery indicates an upper level ridge retreating to the west of the region and Hurricane Harvey approaching the southern Texas coastline. (Friday night through Thursday) Expansion of upper ridging from the northwest should keep the main effects of Harvey to the southeast of the region this weekend.
Meanwhile, the main trough axis still lies to our west and is proceeded by a modest mid/upper jet.
Upper level subtropical ridging persists from northern Mexico to Florida with the jet stream across the northern tier of the CONUS and Canada. Water vapor imagery showing this ridge continue to trap good mid level moisture across all of Texas as well as eastern New Mexico.
High pressure building southward across the midwest this afternoon. Current temps are in the upper 70s Plateau to the lower 80s elsewhere. Dry weather to prevail over the next few days as the aforementioned high pressure area moves slowly eastward. Thermal troughing will remain anchored along the mid Atlantic states into the weekend as well.
Instability and shear will be on the low end once again with only about 1500 J/kg with around 10kt of shear.
Temperatures tonight will be a couple degrees milder than this previous morning but still overall cooler than average.
702 PM EDT Thu Aug 24 2017 High pressure and a seasonably cool airmass will be in place across the region through Friday, before it works off to the east over the weekend. With the airmass modification and the lingering cloud cover, went with lows in the lower to mid 50s tonight. Lows Friday night will be a few degrees warmer, in the upper 50s to lower 60s. The center of high pressure over the Great Lakes will move off to the east over the weekend, but it will continue to extend/influence our weather with dry conditions.
/issued 853 PM CDT Thu Aug 24 2017/ High pressure in place over the Mid South will keep dry conditions along with cool temperatures in place tonight. /issued 259 PM CDT Thu Aug 24 2017/ Pleasant weather for late August across the Midsouth with high pressure to our north keeping conditions dry and clear in the short term with temperatures in the low to mid 80's. A nearly identical day is expected tomorrow with high temperatures ranging from the low 80's in northern areas to the upper 80's in north MS.
Overall, lower heights under a flattened ridge, with a series of Pacific disturbances, will bring a period of increased shower and thunderstorm activity over the next 36-48 hours.
628 PM CDT Thu Aug 24 2017 1024 mb high pressure over western Ontario and ridging southward over western IL and mid MS river valley, will drift over the Great Lakes region during tonight and Friday and continue dry and less humid conditions (dewpoints in the 50s) over central/se IL rest of this week. An upper level trof will remain over the Great Lakes and ohio river valley into Friday with upper level ridging into the high plains putting IL in a nw upper level flow. Lows overnight in the low to mid 50s, coolest from I-74 ne where less mid level cloud cover expected. Nearby high pressure will keep winds fairly light generally less than 10 mph.
20z Water vapor imagery picking up on a large upper low spinning east of the Hudson Bay. A "warm" front extends off this low and cuts through northwestern to north- central Iowa. With the longwave troughing through the Ohio Valley, and Harvey over the western Gulf, Iowa will be moisture starved.
expect a pretty decent summer afternoon with a bit more sunshine and slightly warmer temps by the mid to late afternoon hours.
High pressure building south from the Great Lakes will keep the fall like weather going.
High pressure in place over the Mid South will keep dry conditions along with cool temperatures in place tonight. /issued 259 PM CDT Thu Aug 24 2017/ Pleasant weather for late August across the Midsouth with high pressure to our north keeping conditions dry and clear in the short term with temperatures in the low to mid 80's. A nearly identical day is expected tomorrow with high temperatures ranging from the low 80's in northern areas to the upper 80's in north MS.
Tail end of a trough will help to channel moisture and energy into northwest and northern Wyoming as the afternoon and evening wear on. One area of interest will be the far north where a weak cold front will slide south Friday afternoon and evening. High pressure will become firmly entrenched across the Great Basin this weekend. As a result, drier air will filter into the state from the west-northwest on the northern side of the high.
Meanwhile, the main trough axis still lies to our west and is proceeded by a modest mid/upper jet. It will be a bit cooler on Friday with storms exiting the eastern and southern portions of the region.
Sunny skies and tranquil wx conditions prevail across the cntrl TN Valley this Thu afternoon, as afternoon temps again trend slightly below normal with readings mainly in the lower/mid 80s. Strong area of high pressure continues to build ewd into the Midwest/OH Valley states, thereby helping with the nice wx across the local area today. Temp trends should again quickly fall off into the 70s this evening and then into the lower 60s by early Fri morning under predom clr skies. After another seasonably cool morning Sat in the lower/mid 60s, moisture/cloud cover will begin to gradually increase over the mid TN Valley, as the high pressure shifts ewd towards the mid Atlantic Basin and the sfc flow veers to the E/SE during the day Sat.
For Friday through the weekend, high pressure will build in and provide mainly dry and cool weather. Canadian high pressure at the surface will settle over the area this weekend.
650 PM CDT Thu Aug 24 2017 High pressure will remain over Lake MI tonight and Fri. Medium to High Rather cool and dry high pressure building across WI. The high dominates on Friday though shifts a bit to our east. Some increase in mid clouds noted into the western cwa in closer proximity to the return flow around high while Bufkit shows cu potential with lingering influence of the low level thermal trough.
Area of snow showers accompanying this feature in an area of DPVA aloft in the presence of decently steep lapse rates under the cold upper trough.
Current surface analysis places high pressure over southern Saskatchewan with inverted trough/frontal boundary stretching through the northern plains. Upper level analysis places trough stretching from the Canadian plains towards central Idaho. The focus then shifts towards south central North Dakota into the James River Valley as the upper trough axis swoops through the area, providing enhanced lift with rain developing through the morning, continuing into the afternoon. Rain will then taper from west to east later in the afternoon into the early evening as trough slides off to the east and ridging starts to build in. Broad scale ridging over the area will bring dry conditions to the forecast through much of the week.
Area temp / dewpoints all running 3 - 5 degrees higher than this time yesterday continuing the trend of warmer temps and increasing moisture.
A cold front will move into the area after midnight, reaching ABI around 07Z, SJT/BBD around 09Z and SOA/JCT near 12Z. /issued 416 AM CDT Sat Oct 14 2017/ (Today and Tonight) A cold front and associated good chance of thunderstorms are the main concerns for the short term forecast. We should see temperatures climb into the lower 90s, with breezy afternoon conditions. A cold front will then move southward quickly late tonight, bringing a good chance of thunderstorms, with a few marginally severe across the northern Big Country. Behind the front, we will see cloudy skies, strong north winds, and noticeably cooler temperatures in the 50s.
530 AM MDT Sat Oct 14 2017 Positively-tilted upper trough is pushing into the Rockies, and satellite is showing an increase of clouds across the region. Precipitation and gusty winds are expected today as the trough quickly moves through the region. Behind this trough, broad upper ridging will build over the western and central CONUS, and then transition into zonal flow midweek. A cold front will move through the area, bringing gusty northwest winds along with areas MVFR CIGS in -shra that will last through the day today, clearing NW-SE.
918 AM EDT Sat Oct 14 2017 From satellite imagery we find a TUTT cell rotating northeast of the Bahamas and high pressure well north of the Keys area over the east coast states.
1102 AM EDT Sat Oct 14 2017 High pressure will continue north of the area through Sunday.
We could see a brief mix of warmer temperatures just ahead of advanced cold front later today, and with a mild start in the 50s, have raised temperatures up a bit today. Broad and transitory ridge/height rises aloft will keep rain chances at bay, and likely until next Saturday at the earliest. Though sunny, temperatures will start coolish Sunday, but the rest of the week is pleasant with highs in the lower/middle 70s in general, or roughly 5-8 degrees above normal afternoon high temperatures on average.
729 AM EDT Sat Oct 14 2017 High pressure will continue north of the area through Sunday.
1134 AM EDT Sat Oct 14 2017 Ridge of high pressure across the area will remain in place providing dry weather through Sunday.
VFR conditions are expected to prevail throughout the day with high pressure over the region. This area of high pressure will result in southeast winds of 5 to 10 knots at all area terminals from mid-morning into the afternoon. Will maintain dry weather today as high pressure at the surface and aloft remains over the region. The approach of a frontal boundary and the shifting of the upper ridge eastward will allow increasing chances of showers and thunderstorms on Sunday.
High pressure ridge north of the area will maintain an easterly flow around 10-15 knots nearshore and around 15 knots offshore.
1125 AM EDT Sat Oct 14 2017 High pressure lies over the east coast and southeast states with an extension west over the Tennessee Valley.
Within the lower area of overall pcpn, will also lower pcpn amounts this morning to less than a tenth of an inch. Strongest forcing will likely remain near and south of the ND/SD border (water vapor imagery indicates upper level trough/circulation over Idaho (09z), propagating eastward). As the main upper level trough progresses eastward Sunday large scale subsidence is expected across the area, giving way to clearing skies from west to east throughout the day.
A weak upper level ridge will persist over the eastern Pacific through tonight.
Cold front will arrive at HOB around 06Z/15 with TSRA and MAF/INK by 08Z and it will be at least briefly be very windy with FROPA. /issued 341 AM CDT Sat Oct 14 2017/ Looking at one more summer-like day before a strong cold front arrives tonight with a chance for showers and thunderstorms. A large upper ridge was centered over the central Gulf Coast this morning with our region on its western periphery. Temperatures will be hot for mid October as a mid level thermal ridge sets up over the area.
A mostly sunny, warm, dry and a times breezy day will be seen ahead of a cold front and system. Behind the cold front later tonight and on Sunday, a cooler and drier air mass will filter into AR, and clear any rain mainly Sunday morning. Today Through Sunday Night One more unseasonably warm day expected acrs AR today as high pressure aloft remains in place over the region. Looking at highs today in the mid 80s to the lower 90s. Much cooler and drier air wl advect into the area to close out the weekend.
725 AM EDT Sat Oct 14 2017 A cold front slowly moves toward the region today.
The morning FG/low stratus just SW of the region has quickly lifted this morning, but should see a good cu field develop by midday/early afternoon as diurnal heating increases beneath the broad ridging aloft that still lingers from S TX ENE across the Gulf Coast region into the Mid-Atlantic area. Did have to update the forecast this morning to remove the patchy FG mention this morning across the Srn zones, and also bumped up max temps 1-2 degrees given the 15Z temps running a little warmer than expected. Our much anticipated cold front remains slated to plow through the region Sunday, offering a good cooldown but unfortunately, very little rainfall.
Based on this, did adjust the higher rain chances accordingly. Strongest forcing will likely remain near and south of the ND/SD border (water vapor imagery indicates upper level trough/circulation over Idaho (09z), propagating eastward). As the main upper level trough progresses eastward Sunday large scale subsidence is expected across the area, giving way to clearing skies from west to east throughout the day.
952 AM EDT Sat Oct 14 2017 Forecast on track as classic E-NE flow and coastal trof in the Atlc Waters will continue to help develop coastal showers in the convergence along the coast and push them onshore at times through the day.
Meanwhile partly to mostly sunny skies over southeast IL to warm temperatures (currently in the lower 70s), into the mid 80s by mid afternoon. Then as the low continues by late evening, moving into southern WI, it will pull cold front east over southeast IA and MO. High pressure will be in control of weather pattern through the week.
226 PM MST Mon Sep 11 2017 Dry air moving into the region will end rain chances starting today while also bringing warmer temperatures through the middle of this week.
Upper ridge of high pressure remains parked over Colorado with light flow aloft but a bit of a westerly flow over northern Colorado. Temperatures will be a bit cooler today with cloud cover and slightly cooler low levels.
Otherwise, temps today ended up trending warmer in many areas, especially coastal sites, despite a 3mb onshore trend and humidities that are actually higher than yesterday. Temps Tuesday expected to trend cooler with the increase in onshore flow, drier air aloft, and some increase in marine lyr clouds. With the upper low remaining well offshore not expecting much in the way of convective development Tuesday except for some afternoon cumulus over the interior.
A cold front was crossing through the far southeast part of the forecast area early this Monday morning and pushing south and east. A bit cooler today, post frontal, and then comfortably cool tonight. Hot Tuesday, 90s, normal highs in the 70s for the second week of September, as a thermal ridge axis / 24 to 27 degrees C at H8/ pokes into the southwest. Ahead of a low pressure trough dew points increase enough, 60 Bismarck through Jamestown, that it might feel a bit on the sticky side.
114 PM EDT Mon Sep 11 2017 High pressure over the eastern Great Lakes today, will bring fair and mild weather through Tuesday as it move across our area towards the mid Atlantic coast.
/Tonight through Tuesday/ Little change in the weather over the next 24 hrs as high pressure ridge remains in place. Light winds and persistent temperatures with low temperatures tonight generally in the 50s and highs on Tuesday in the low to mid 80s.
This will lift a warm front northward through North Carolina later tonight through Tuesday. The northward surging warmer air will push a warm frontal boundary across the area ahead of onshore plume of moisture.
253 PM PDT Mon Sep 11 2017 Ridge of upper level high pressure across Southern Oregon and Idaho will gradually break down over the next several days. A trough of low pressure will deepen and drop south out of Northern BC through central Washington by late this week.
Seeing temperatures mainly in the low 80s while dewpoints remain in a very pleasant 55-60 range.
Tonight and Tuesday The latest RAP analysis and satellite/radar imagery show high pressure centered over the eastern Great Lakes, but extending west into the mid-Mississippi Valley. Meanwhile, a weak cold front is moving southeast over northern Minnesota and remains void of any precip early this afternoon due to a dry and stable airmass in place over the western Great Lakes. But low level moisture will increase along the front, which is already evident by dewpoints rising into the low to mid 50s across the area this afternoon. Low level temps will continue to warm, which should bring highs into the upper 70s to lower 80s, but cooler near the Lake. Tuesday Night Through Monday With the westerlies to the north and an upper low to the south, upper ridging is forecast to continue across Wisconsin through the end of the week.
Winds will become more southerly drawing up warmer air at 850mb between 6z and 18z. The trough is not expected to trigger any showers through Tuesday afternoon.
125 PM MDT Mon Sep 11 2017 The latest water vapor images and short-term model analyses showed high pressure covering much of the western into central CONUS with an upper low just southwest of CA and tropical storm Irma moving across the Southeast as it starts to make its extratropical transition. There were some weak cumulus clouds over the highest BLKHLS this afternoon where MLCAPE was 100-200 J/kg.
645 PM EDT Mon Sep 11 2017 High pressure will keep clear conditions over Central NY and Northeast PA through Tuesday evening. As is typical when our region is affected by strong high pressure close to the autumnal equinox, we will see huge temperature swings between day and night and deep valley fog during the early morning. High pressure will yield a picture-perfect sunny day. Ridging, both surface and aloft, is expected to nudge eastward and off the east coast during the mid-week period. This is expected to allow an upper-level trough (the remnants of Irma) to move into the mid-Atlantic states.
