Dry and generally mild conditions will persist over the next several days under the influence of high pressure. Dry cold fronts are expected to bring slight cooling and some gusty winds on Thursday as well as late in the weekend.
926 AM EDT Wed Apr 7 2021 High pressure remains over the area making for another beautiful morning across west central and southwest Florida. A cool morning will warm up nicely under sunny skies topping out in the low to mid 80's this afternoon. High pressure over the area will produce pleasant weather for boating on the eastern gulf waters for the next few days.
A broad high pressure ridge is in place over central California with just some thin high cloudiness riding across the ridge overhead.
648 AM EDT Wed Apr 7 2021 High pressure remains centered across the southeastern states with a weak stationary front across the area. Another area of low pressure approaches from the west later in the week. Otherwise, partly cloudy with high temps in the lower 80s inland and much cooler at the coast, especially at Ocean City where temps may struggle to reach 60 with onshore flow most of the day. Slightly cooler on Thursday with increasing clouds and stronger onshore flow due to the high from New England ridging down the Atlantic coast.
Boxell (Issued 356 AM CDT Wed Apr 7 2021) Today through Thursday night: Low pressure will gradually approach from the southwest today into tonight, lifting northward just west of the forecast area on Thursday. Moisture will increase from the southwest in advance of the low today, with a chance for a showers and a few storms developing in the afternoon, mainly across the southwest forecast. More rounds of showers and a few storms will be likely this evening into Thursday, spreading farther toward the northeast as the low lifts through the region. It will also be cooler towards Lake Michigan due to onshore winds. It will remain mild tonight away from Lake Michigan, with cooler conditions near the lake. Temperatures Thursday will be cooler largely due to more clouds and lingering showers, though highs will remain above normal.
Meanwhile, in the upper levels, a weak ridge is slowly pivoting through with an upper level trough sitting across the extreme eastern Pacific and Mexico. This upper level trough is streaming high level cirrus across the region from the southwest. Meanwhile, the upper level ridge over the area will slowly slide east. That being said, the upper level trough over the extreme eastern Pacific and Mexico region, will continue to stream in high level cirrus at times. As we get closer to the weekend, expect a new trough to slide southeast from the Pac NW and settle across the central U. This will help to nudge the upper level ridge east just enough to allow for deep layer southerly flow to transport moisture from the NW Caribbean.
833 AM EDT Wed Apr 7 2021 High pressure building south from Eastern Canada will control our weather into the weekend. Temperatures associated with this high will moderate to above normal levels over many inland locations.
648 AM CDT Wed Apr 7 2021 (Today and tonight) As of 3 AM, a weak cold front was entering far northern portions of the Big Country. Temperatures will be cooler today, but still above normal, with highs ranging from the upper 70s across the Big Country, to the lower and middle 80s elsewhere.
638 AM EDT Wed Apr 7 2021 High pressure will cover the southeast United States, as a weak stationary front trailed from the Great Lakes to the Mid Atlantic states.
444 AM MDT Wed Apr 7 2021 Current surface map places low along the NE/IA border with associated upper low moving into western Kansas.
Temperatures will trend seasonably cooler with periods of rain from late week into the weekend. Otherwise, upper ridging building into the region should supply a partly to mostly sunny and warm Wednesday. Any isolated showers over the central mountains should die with loss of heating around sunset, then mild and dry conditions are anticipated the rest of tonight under 500mb ridge. High pressure building south from New England should ensure fair weather Thursday. However, the resulting southeast flow off of the Atlantic should result in a slightly cooler day than those recently with highs between 65-70F.
458 AM CDT Wed Apr 7 2021 Periods of showers and non-severe thunderstorms are expected for the next several days as an area of low pressure slowly moves across the region.
Expect another round of elevated srly winds as the gradient tightens with deepening low pressure over the Plains.
321 AM MDT Wed Apr 7 2021 Latest GOES-16 WV imagery shows the upper level low continuing to move into western KS. WV imagery over the CWA has been drying out over the past few hours with on and off light snow being reported as the upper low continues to propagate to the east. Latest RAP analysis does depict a vort max on the back side of the low that is contributing to additional snowfall along the South Laramie Range early this morning.
601 AM CDT Wed Apr 7 2021 A mid/upper low over the TX/OK Panhandle region will lift to southern Lake Michigan through Thursday. Temperatures will sneak into the 70s for one more day, generally along and east of Interstate 35 as a warm front lifts into the southeastern portion of the area.
1012 AM EDT Wed Apr 7 2021 High pressure will cover the southeast United States, as a weak stationary front trailed from the Great Lakes to the Mid Atlantic states.

Current surface map places low along the NE/IA border with associated upper low moving into western Kansas.
604 AM MDT Wed Apr 7 2021 Latest GOES-16 WV imagery shows the upper level low continuing to move into western KS. WV imagery over the CWA has been drying out over the past few hours with on and off light snow being reported as the upper low continues to propagate to the east. Latest RAP analysis does depict a vort max on the back side of the low that is contributing to additional snowfall along the South Laramie Range early this morning.
High pressure maintains excellent boating conditions.
642 AM EDT Wed Apr 7 2021 High pressure crosses today.
1019 AM EDT Wed Apr 7 2021 High pressure remains centered across the southeastern states with a weak stationary front across the area. Another area of low pressure approaches from the west later in the week. Another warm and sunny day expected as high pressure over the Southeastern US remains in control. This should allow for mainly light southerly to southwesterly flow today, which should allow readings to climb into the upper 70s to lower 80s across VA/NC but slightly cooler over the Delmarva with readings in the lower 70s as they are closer to the next back door front expected late tonight into Thursday. Slightly cooler on Thursday with increasing clouds and stronger onshore flow due to the high from New England ridging down the Atlantic coast.
551 AM CDT Wed Apr 7 2021 12Z TAF issuance A cold front continues to move through with some patchy BLDU and visbys down to 5SM. /issued 404 AM CDT Wed Apr 7 2021/ Latest sfc obs show a weak cold front diving S into our CWA with gusty winds in its wake.
High pressure will prevail resulting in generally benign boating conditions through mid week.
It will be a Summer like day today as the area will be fully in the warm sector behind a warm front currently across north central lower Michigan and under the upper level ridge axis. With plenty of sunshine temperatures will reach around 80 most locations but considerably cooler along and near the shoreline in the Thumb with an onshore breeze.
/Issued 438 AM CDT Wed Apr 7 2021/ A departing closed upper low over the central Plains states in southern Kansas will create strong northwesterly winds of 25 to 35 mph or higher and gusts as high as 55 mph on the backside of the upper low as subsidence prevails. The stronger winds should remain north of the Panhandles and the winds should gradually diminish during the day today as the upper low moves further east away from the forecast area and the gradient relaxes. Cooler and dry conditions through the end of the week with another reinforcing cold front forecast Thursday night.
559 AM MDT Wed Apr 7 2021 Weak H5 ridge builds back across the state today behind the departing trough. This ridging will be brief, as the next in a series of troughs races across the intermountain west. This trough will be accompanied by a cold front racing across the state later in the afternoon Thursday. This trough has enough instability that a clap or two of thunder cannot be ruled out as it passes. An upper-level trough and associated low will drag a cold front across the area Thursday evening. As the trough digs and the jetstreak traverses the area, increased gusty winds will be likely across the southern zones.
715 AM EDT Wed Apr 7 2021 High pressure builds over the area through Thursday, while a slow moving storm system approaches from the Midwest.
/issued 338 AM EDT Wed Apr 7 2021/ High pressure will remain over the region through the end of the week, with gradually warming temperatures and increasing humidity.

Rain chance returns Thursday as low pressure approaches the region. Otherwise, high pres wl cont to build over the Upr OH with the upr ridges axis progged to slide ovr the immediate area this aftn. Rain and the chance for some thunderstorms returns Thursday as a trough in the Great Plains advances east into the Midwest. Rain showers will continue to advance through the region Thursday night as the low pressure pivots and tracks north, just west of the Great Lakes.
High pressure will be the dominate weather feature for the foreseeable future bringing above normal daytime temperatures and typical springtime breezes each afternoon. High pressure building in across the area will bring warming temperatures, clear skies, and continued dry conditions. The strongest winds will be on Thursday, when an area of low pressure passes by well to our north.
Closed upper low moving into the central plains this morning, will push slowly east today/tonight, then up into OH valley on Thu. Once this pcpn moves east, it will not be the end with the main cold front hanging way back. But during that period, a secondary closed upper low will spin down into northern plains and SFC wave will form along the cold front. This SFC wave will move just to our west early Sat morning, with the cold front later in the day. This will bring another round of widespread showers/storms to the area starting late Fri night, lasting at least into Sat evening, until the trailing upper trough passes. After 08/03Z a band of showers and storms ahead of a cold front will move into Middle Tennessee.
Pleasant conditions are expected today as high pressure builds over the region. A cold front will bring gusty winds and cooler temperatures to primarily northeastern Nevada Thursday.
248 PM CDT Wed Apr 7 2021 A cold front was in the process of making its way through the Ozarks this afternoon. Behind the front only a few lingering showers are expected with cooler temperatures and lingering cloud cover. The upper low will linger over the state and swing another piece of energy around the back side of the low.

Added isold showers through the rest of the afternoon based on radar and meso analysis, mainly NE-E of PIT, where convection has developed just ahead of the upper ridge axis. The midday update featured an upward temperature tweak to around the 80 F mark given the strengthening ridge and abundant insolation across the Upr OH. With the upr ridge axis progged to slide ovr the immediate area this aftn.
Visible satellite continues to show high level cirrus streaming in thanks to an upper level trough that lies to our west and southwest. Otherwise, there's hardly a cloud in the lower levels.
Warm air advection combined with the arrival of some mid and high clouds should prevent freezing temperatures from recurring in valleys with susceptible vegetation. A mid-level trough moving across the northern Rockies will drive an increase in winds aloft which will mix to the surface from late morning into the afternoon on Thursday. As the trough moves southeastward across the northern portion of the forecast area on Thursday night, it will drive its associated cold front to the Four Corners region late.

258 PM CDT Wed Apr 7 2021 Showers and thunderstorms are expected to be numerous tonight across central Illinois, as an upper level low moves east out of Kansas.
A few showers will be possible this evening in north central Oklahoma, associated with wrap-around precipitation from the departing low pressure system.
Given the increased sunshine temperatures this afternoon are running a few degrees warmer than yesterday at this time. No precip either as the ridge of high pressure currently over the region builds and retrogrades westward with a blocking pattern feel. The only item of note over the next seven days is an upper low swinging through the region next Tues/Wed. One operational model, the GFS, brings the upper low farthest west, but still doesn't generate any precip. SFO Bridge Approach.
1115 AM MDT Wed Apr 7 2021 Weak H5 ridge builds back across the state today behind the departing trough. This ridging will be brief, as the next in a series of troughs races across the intermountain west.

KSHV 18Z sounding shows this morning's cap has all but been flattened, indicating the anticipated increase in instability as the cold front approaches. A cold front, that is knocking on our CWA border, will bring a line of showers and thunderstorms to the area by this afternoon. /issued 1147 AM CDT Wed Apr 7 2021/ A line of showers have developed along a pre-frontal trough moving across the region this morning. At 1030 AM, a closed upper trough was located across Western Kansas, with a cold front trailing along the I-35 corridor of Oklahoma and Texas. As this trough and associated cold front continues to move eastward today, a line of showers and thunderstorms will initially develop across East Texas and adjacent SE Oklahoma early this afternoon, and eventually move across the remainder of the region.
Warm and breezy conditions this afternoon are common as high pressure flattens with a trough approaching from the west. The cold front associated with the incoming trough is projected to pass through the region overnight. Breezy winds, rain and snow, and lowering snow levels are all expected with the cold front.
1141 AM MDT Wed Apr 7 2021 Latest GOES-16 WV imagery shows the upper level low continuing to move into western KS. WV imagery over the CWA has been drying out over the past few hours with on and off light snow being reported as the upper low continues to propagate to the east. Latest RAP analysis does depict a vort max on the back side of the low that is contributing to additional snowfall along the South Laramie Range early this morning.
High pressure aloft continues over the area through the short term. As the front gets closer, the high will shift a bit south which will allow for increasing southeasterly flow on Thursday compared to today. Temperatures will remain around seasonal averages with upper 70s/lower 80s along the coasts and mid to upper 80s inland for the highs and 60s around the coasts and mid to upper 50s inland. Dry conditions will continue for the end of the week and into the first part of the weekend as a deep layer ridge of high pressure pushes off into the western Atlantic. Highs will rise into the lower to mid 80s across the east coast metro areas to the lower 90s across portions of Glades and Hendry Counties.
