1216 AM EDT Wed Aug 30 2017 High pressure will slowly move east of the region through Wednesday. Low pressure will track well south of Maine Wednesday.
Dry and mild conditions will prevail overnight with just a few patches of clouds rotating around the upper level ridge. High pressure aloft will remain over the Great Basin through Wednesday. Convective activity is sticking mostly to the mountains this afternoon and Cheyenne Ridge this afternoon, heading south in the northerly flow aloft. Expect similar temperatures tomorrow, perhaps a degree or two warmer.
1006 PM EDT Tue Aug 29 2017 Weak high pressure will build into the area through Wednesday. Dewpoints remain in the lower to mid 60s, as low level moisture remain high. Lows will fall to near the current dewpoints, in the lower to mid 60s. However, most of the higher res models are keeping our area mainly dry so will just allow for a 20 pop across northeast portions of our area through the afternoon. Lows Wednesday night will mainly be in the lower 60s.
1054 PM EDT Tue Aug 29 2017 Low pressure, located near Cape Hatteras this evening, will track northeast and out to sea tonight. A ridge of high pressure will build into Pennsylvania late tonight and Wednesday.
Expect a few lingering showers to dissipate by late evening with low temps tonight in the low to mid 60s. This precip is in response to a diffuse surface boundary trailing behind a closed upper low moving slowly across the Great Lakes. A moisture-starved wave in the NW flow swings through on Wednesday, but by Wednesday night all eyes turn to the south as the remnant low of Harvey starts to lift through the lower Mississippi Valley.
1249 AM EDT Wed Aug 30 2017 A weak warm front will linger nearby through mid week before a cold front approaches from the north late in the week. High pressure to the north will give way to some deeper moisture Wednesday north of a stationary front near the Gulf coast, which should push north into or even through the area Wednesday night as low pressure, once Hurricane Harvey, moves northeast from the Lower Mississippi Valley.
711 PM CDT Tue Aug 29 2017 Large upper ridge aloft across the northern US with an upper trough across southeastern Canada into the Great Lakes Region/Northeast.
1051 PM MDT Tue Aug 29 2017 Some clouds and smoke are streaming into the region through northwest flow, as an upper ridge persists over the western CONUS. An upper trough will begin to break down the ridge on Wednesday.
North and northerly flow around Harvey continues to bring a cooler and drier air mass into the region. Lows tonight will drop into the lower 60s for most locations, with even a few upper 50s in a few areas.
755 PM EDT Tue Aug 29 2017 Low pressure, located near Cape Hatteras this evening, will track northeast and out to sea tonight. A ridge of high pressure will build into Pennsylvania late tonight and Wednesday.
546 PM MDT Tue Aug 29 2017 A rinse-and-repeat forecast through Wednesday as a strong ridge of high pressure remains overhead. Moisture lingering under the ridge will continue to be recycled today and tomorrow to produce isolated showers and thunderstorms over the higher terrain. An upper level trough will elongate off the coast of the Pacific Northwest throughout the day on Wednesday. The progression of the trough further inland will help flatten the ridge for the latter half of the week.
1151 PM CDT Tue Aug 29 2017 Large upper ridge aloft across the northern US with an upper trough across southeastern Canada into the Great Lakes Region/Northeast.
High pressure aloft will shift further south and flatten over the next 24 hours.
1134 PM EDT Tue Aug 29 2017 Low pressure, located near Cape Hatteras this evening, will track northeast and out to sea tonight. A ridge of high pressure will build into Pennsylvania late tonight and Wednesday.
951 PM EDT Tue Aug 29 2017 A weak warm front will linger nearby through mid week before a cold front approaches from the north late in the week. High pressure to the north will give way to some deeper moisture Wednesday north of a stationary front near the Gulf coast, which should push north into or even through the area Wednesday night as low pressure, once Hurricane Harvey, moves northeast from the Lower Mississippi Valley.
Drier/more stable air building in from south Florida combined with the weakening surface convergence near the trough resulted in considerably lower coverage of showers and storms this afternoon, especially south of Interstate 4. Trough axis lifts northward with a light and somewhat variable wind flow overnight.
509 PM MDT Tue Aug 29 2017 Some clouds and smoke are streaming into the region through northwest flow, as an upper ridge persists over the western CONUS. An upper trough will begin to break down the ridge on Wednesday.
838 PM EDT Tue Aug 29 2017 Low pressure will move northeast away from the Virginia coast tonight. Weak high pressure will build over the area Wednesday.
Extensive surface ridging will help keep forecast dry.
Harvey is showing more and more extra-tropical characteristics with an apparent dry slot noted on water vapor imagery that is streaming northward into the lower MS valley.
Partly cloudy VFR conditions are expected Wednesday ahead of an approaching cold front. Could see a few showers/storms move through north to south late afternoon into the evening hours as the cold front drops through the area. Ceilings may drop to MVFR for a time near and behind the cold front. Warmer air will drift into southern WI ahead of an approaching front on Wednesday, so high temperatures will end up warmer than today with values in the upper 70s.
632 PM CDT Tue Aug 29 2017 Weak cold front will continue to slide south through northern North Dakota this evening. A weak cold front across Saskatchewan and into Manitoba was pushing south. For Wednesday, cooler behind the front, 75 to 85, though closer to 90 southwest nearer the thermal ridge.
Weak high pressure will build into the area through Wednesday. However, most of the higher res models are keeping our area mainly dry so will just allow for a 20 pop across northeast portions of our area through the afternoon. Lows Wednesday night will mainly be in the lower 60s.
GAH PREVIOUS SHORT TERM DISCUSSION: An upper ridge parked over the western states will be shift east a bit into Wednesday as a trough off the West Coast moves in. There will be a trough working its way into the Pacific Northwest.
Tonight through Wednesday, A broad upper ridge will remain across the western conus. Upper level ridging across the western CONUS will deamplify by late week as a northern stream trough traverses the northern Plains. The aforementioned trough will absorb the remnants across the Ohio Valley.
Cold front has now made it about a third of the way southward across the area and should be into GFK shortly. Cold front just across the International border along a line from Lake of the Woods to Hallock to Rolla and will continue to slowly drop southward throughout the night. CAMs continue to show most activity east of the forecast area as a cold front moves south out of Manitoba this evening. Less capping with cooler mid level temps to the northeast of the area will allow convection to develop. In its wake winds will be northeasterly tomorrow with 925mb temps 5 to 10C cooler than the today.
657 PM CDT Tue Aug 29 2017 Upper air and satellite data continue to show well amplified north- northwesterly flow across the region, thanks to a large area of high pressure/ridging affecting the western half of the CONUS. At the surface, high pressure is centered over eastern NE up through western WI, keeping winds across the area light/variable to east-southeasterly around 5-10 MPH. At the surface, high pressure is shown by models to be centered a touch further east than it was this morning, but it's still in close proximity. Highs for tomorrow are forecast to be similar to today, reaching the lower to mid 80s.
633 PM CDT Wed Nov 1 2017 Water vapor imagery this afternoon showing a broad upper trof prevailing across the CONUS. unorganized low pressure was situated over WY with attendant warm front extending through NE into northern MO.
Dry, quiet, and warmer weather can be expected tonight. A cold front associated with this low will bring cooler air into northern Oklahoma by 02/2400Z, and some low-level moisture is likely to follow the front into north-central Oklahoma. A weak cold front will move across far northwest Oklahoma early Thursday morning and will continue south during the afternoon and early evening.
745 PM EDT Wed Nov 1 2017 Rain will continue through the night as a warm front lifts north over the area.
Temperatures as of 7pm were in the low to mid 70s and should generally fall into the 60s by midnight, aside for some low 70s across the Miami and Fort Lauderdale metropolitan area.
1210 AM EDT Thu Nov 2 2017 Rain will continue for areas mainly from Pittsburgh north through early morning with a crossing warm front.
This looks like it will slide along the highway 2 corridor, and will likely bring some light accumulations with it. This low has been associated earlier with 1-2 inches of snow accumulation upstream thru SE Saskatchewan and the idea of the forecast is that 1-2 inches of snow will remain possible as it moves through area along the International border. Generally dry but cloudy on Thursday with highs a few degrees either side of freezing.
These conditions will improve by late morning into the early afternoon with VFR conditions returning at most sites with southerly winds increasing to around 15 kts with higher gusts up to 25 kts or more, allowing for more mixing to scatter out the lower clouds. In addition, due to the clear skies across east TX, temperatures were a few degrees cooler than what was initially exhibited in the previous forecast package.
Winds are starting to taper off north of the Missouri River this evening as the low pressure system continues to push off to the southeast. Light shower activity is quickly tapering off this afternoon as low pressure at the surface pushes into North Dakota, allowing cool Canadian high pressure to fill in behind it. Thursday weak ridging will build in as upper level low pressure digs to the west, continuing the dry spell.
1031 PM EDT Wed Nov 1 2017 Currently - High pressure extending down the Atlantic coast and into the Gulf of Mexico is producing gentle to moderate northeast to east breezes across the Florida Keys. Temperatures are in the low to mid 70s with dew points in the mid 60s. Short Term Update - Gentle northeast to east breezes will prevail overnight due to the high pressure to our north. Moderate northeast to east breezes will prevail across Florida Keys waters as high pressure remains across the eastern United States and Gulf of Mexico.
A cold front associated with the low pressure area will also move into northern and central Oklahoma, causing a more abrupt wind shift. Dry, quiet, and warmer weather can be expected tonight. A cold front associated with this low will bring cooler air into northern Oklahoma by 02/2400Z, and some low-level moisture is likely to follow the front into north-central Oklahoma. A weak cold front will move across far northwest Oklahoma early Thursday morning and will continue south during the afternoon and early evening.
1018 PM CDT Wed Nov 1 2017 Snow continued to fall over much of the Northland with some freezing drizzle occurring as the snow diminishes. It's possible some freezing drizzle is occurring there but calls to a few spotters reveal mainly snow or the precipitation was very light. However, the Minnesota North Shore can expect 3 to 6 inches, and possibly up to 8 inches in the higher terrain, because of lake enhancement and terrain effects. There is a very low risk of freezing drizzle or light freezing rain in the wake of the snow late this afternoon and this evening when some drier air moves in aloft.
In addition, due to the clear skies across east TX, temperatures were a few degrees cooler than what was initially exhibited in the previous forecast package. Conditions will improve by late morning into early afternoon with VFR conditions returning at most sites as southerly winds increase to around 15 kts with higher gusts up to 25 kts or more, allowing for more mixing to scatter out the lower clouds. /issued 547 PM CDT Wed Nov 1 2017/ Warm frontal boundary has moved north of I-30, and at the same time overrunning rains are about to move east of the area. A Lake Wind Advisory may be required for western portions of the cwa tomorrow aftn with aftn temps ramping up to the lower to possible middle 80s.
650 PM CDT Wed Nov 1 2017 The evening forecast will be dominated by a persistent low level southerly flow into central Illinois, as a warm frontal circulation develops to our northwest, centered from across NW Missouri and into NW Illinois. There appears to be increasing evidence in the low level thermal and moisture profiles that low clouds, fog, and patchy drizzle will be possible overnight tonight, as synoptic scale lift persists in the warm advection flows. Thursday night will see ongoing showers east of I-55, as a surface wave progresses to the NE along the warm front, and exits into Indiana.
827 PM EDT Wed Nov 1 2017 High pressure northeast of the area will keep a light easterly wind in place with calm conditions expected across most inland locations overnight.
Quite a bit of cloud cover over the Great Valley tonight, but it appears vfr conditions should be maintained as warm and moist air is lifted over relatively cooler air in place across the Southern Appalachian region.
A cold front associated with this low will bring cooler air into northern Oklahoma by 02/2400Z, and some low-level moisture is likely to follow the front into north-central Oklahoma. A weak cold front will move across far northwest Oklahoma early Thursday morning and will continue south during the afternoon and early evening.
/Thursday night through Wednesday/ Ridge of high pressure will remain over Iowa Thursday night resulting in light northerly flow and cool temperatures.
906 PM EDT Wed Nov 1 2017 The warm front continues to lift north at this hour, taking the bulk of the measurable rain with it. Did want to note the the next best chance for measurable rain will be with a secondary surge in the low level jet over south central and east central KY overnight. A warm front is draped across central KY this afternoon, with a widespread area of showers spreading ENE north of the WK/BG parkways. As the warm front surges north of the area tonight, coverage of showers will be spotty at best. The vast majority of the day looks dry, which will allow temperatures to surge into the lower 70s.
/issued 345 PM CDT Wed Nov 1 2017/ (Tonight and Thursday) Lee trough will continue to bring breezy southwest winds, especially in the Concho Valley and Big County Thursday.
1141 PM CDT Wed Nov 1 2017 Water vapor imagery this afternoon showing a broad upper trof prevailing across the CONUS. unorganized low pressure was situated over WY with attendant warm front extending through NE into northern MO.
Zonal flow aloft with high pressure centered near Apalachicola with easterly low level flow beneath a strong temperatures inversion around 5,000 ft. High pressure will continue to ridge across the area through the weekend allowing temperatures and moisture to moderate, with highs returning into the lower to mid 80s and lows in the 60s.
/issued 848 PM CDT Wed Nov 1 2017/ Broad upper level troughing remains in place as much of the Mid South is now positioned within a warm and moist maritime tropical airmass. Overnight low temperatures should remain quite warm with most locations remaining in the lower 60s with unseasonably humid conditions. /issued 319 PM CDT Wed Nov 1 2017/ A warm front has lifted into Kentucky and Missouri resulting in strengthening southerly flow across the Midsouth. Despite widespread cloud cover, strong warm advection will keep temperatures trending warmer tomorrow.
Otherwise, high pressure will extend across the area through the end of the week. The moist S-SW return flow was mainly confined to areas along and west of the Appalachians, with the ridge axis located over the Piedmont. There may be a sprinkle or two later tonight, but essentially only trace amounts expected with ridging east of the Appalachians. Accordingly, humidities will be a bit higher tomorrow as dew points climb to the mid and even upper 50s to complement highs climbing to the low to mid 70s.
718 PM EDT Wed Nov 1 2017 Light rain will taper off across the region overnight as a warm frontal boundary lifts north. Shower activity had really decreased after the warm front went through, so lowered PoP across much of the region, but added a slight chance in the mountains. A surface warm front continues to lift northward, causing surface winds to shift out of the south. This will bring in warmer air through the overnight period, likely resulting in early evening minimum temperatures before gradually rising through the remainder of the night. Towards the surface, high pressure settled over the southeastern CONUS will set up return flow with moisture flowing northward into the OH Valley region.
1216 AM EDT Thu Nov 2 2017 A warm front slowly approaches from the south tonight into Thursday morning.
515 PM MDT Wed Nov 1 2017 Upper level analysis shows a broad trough covering the CONUS, with a 110-kt jet in northwest flow pushing into the northern plains. Behind the cold front, winds are northwesterly around 10 to 15 kts. Forecast soundings indicate the potential for some light freezing rain east of the Hills and also across northwestern SD, as well as a little snow.
953 PM CDT Wed Nov 1 2017 Currently, low pressure was located along the ND/SD border near Ashley. An inverted trough extended from the low northwest to near Watford City. Upper level analysis places a broad trough over the central United States, with a compact wave zipping through our area which is leading to an area of light rain and snow now sliding mainly through central North Dakota from west to east. For Thursday, weak ridge passes on over bringing a relatively quiet day to most locations.
1143 PM CDT Wed Nov 1 2017 The steady band of snow is shifting into northwest Minnesota now, but mainly staying along the highway 2 corridor. This low has been associated earlier with 1-2 inches of snow accumulation upstream thru SE Saskatchewan and the idea of the forecast is that 1-2 inches of snow will remain possible as it moves through area along the International border. Generally dry but cloudy on Thursday with highs a few degrees either side of freezing.
Conditions will improve by late morning into early afternoon with VFR conditions returning at most sites as southerly winds increase to around 15 kts with higher gusts up to 25 kts or more, allowing for more mixing to scatter out the lower clouds. /issued 547 PM CDT Wed Nov 1 2017/ Warm frontal boundary has moved north of I-30, and at the same time overrunning rains are about to move east of the area. A Lake Wind Advisory may be required for western portions of the cwa tomorrow aftn with aftn temps ramping up to the lower to possible middle 80s.
1047 PM EDT Wed Nov 1 2017 High pressure will ridge into the forecast area through the rest of the week. Temps will continue above normal, especially during the afternoon hours, where highs will be 10 degrees or so warmer than usual for early November.
Broad upper level troughing remains in place as much of the Mid South is now positioned within a warm and moist maritime tropical airmass. Overnight low temperatures should remain quite warm with most locations remaining in the lower 60s with unseasonably humid condiitons. /issued 319 PM CDT Wed Nov 1 2017/ A warm front has lifted into Kentucky and Missouri resulting in strengthening southerly flow across the Midsouth. Despite widespread cloud cover, strong warm advection will keep temperatures trending warmer tomorrow.
848 PM MDT Wed Nov 1 2017 Have updated the zones to cancel the High Wind Warning for the Front Range mountains and foothills. This will continue to bring high winds to the higher elevations through the evening hours. The High Wind Warning will continue until midnight but could be ended earlier if speeds drop below threshold. Models have a weak back door cold front entering the eastern plains by Thursday afternoon. Temperatures for Thursday will be slightly cooler given the lack of warming from downsloping and the weak frontal passage with highs in the mid to upper 60s.
The low cloud deck should break up around noon or shortly thereafter and return again in the late evening hours Thursday.
Hickford Winds are starting to taper off north of the Missouri River this evening as the low pressure system continues to push off to the southeast. Light shower activity is quickly tapering off this afternoon as low pressure at the surface pushes into North Dakota, allowing cool Canadian high pressure to fill in behind it. Thursday weak ridging will build in as upper level low pressure digs to the west, continuing the dry spell.
Visible satellite shows the low stratus over eastern Kansas most of the morning and afternoon slowly progressing eastward. With the slow moving cloud cover, high temperatures today (especially in very eastern Kansas) have been lowered slightly into the low 60s to mid- 50s. A few sprinkles cannot be ruled out early morning as well as the front passes through as decent vertical motion at the low levels is seen, although have kept this mention out of the forecast for now as coverage would be sporadic with how shallow the saturated layer looks at this time.
903 PM EDT Wed Nov 1 2017 Rain will continue through the night as a warm front lifts north over the area.
A warm front is situated north of Middle Tennessee this afternoon, with warm, moist air advecting from the south and driving temperatures and dew points higher, and patches of light rain still moving across the mid state.
/issued 319 PM CDT Wed Nov 1 2017/ A warm front has lifted into Kentucky and Missouri resulting in strengthening southerly flow across the Midsouth. Despite widespread cloud cover, strong warm advection will keep temperatures trending warmer tomorrow.
/issued 236 PM CDT Wed Nov 1 2017/ A broad upper level trough is over the northern part of the country and westerly flow is over the CWA. A more zonal flow pattern will take shape for Thursday; otherwise, conditions will be similar to today with temperatures perhaps a degree or two warmer.
1000 PM CDT Wed Nov 1 2017 The band of steadier snow continues to work east along the highway 2 corridor. Bumped up snowfall amounts more into the 1 to 2 inch range for most areas along the highway 2 corridor. This low has been associated earlier with 1-2 inches of snow accumulation upstream thru SE Saskatchewan and the idea of the forecast is that 1-2 inches of snow will remain possible as it moves through area along the International border. Generally dry but cloudy on Thursday with highs a few degrees either side of freezing.
Surface wet- bulb temepratures will be a few degrees above freezing across southern MN so precipitation tomorrow morning around sunrise will be light rain.
Low temperatures look decent tonight in the low to mid 50s.
At the surface, low pressure was centered over the central High Plains, with a warm front extending east from the low across northern OK and then northeast into the Ozarks and central MO. Another warm front, separating a modified CP airmass from a more moisture rich Gulf airmass, was located from southeast TX up into the Arklatex. The latest hi-res models develop widespread dense fog across KS to the north of the warm front. The HRRR maintain low cloud and fog only over the ridge tops of the Boston and Ouachita Mountains and shows very little outside of that. The southern warm front is not making much progress to the northwest, with the better surge of moisture lifting north over LA and into southern AR.
620 PM CDT Wed Nov 1 2017 Moisture levels and warmer air will continue to lift north across the state overnight.
750 PM EDT Wed Nov 1 2017 Weak high pressure will re-establish over the Mid-Atlantic tonight into Thursday.
