214 AM EDT Sat Mar 20 2021 High pressure remains in control through the weekend. Dry weather and clear skies are expected today as high pressure remains in control over the region. Temperatures will be slightly warmer than normal with afternoon highs in the upper 50s to low 60s in the lowlands, and 40s to 50s in the mountains.
Temperatures should top out in the lower 60s this afternoon.
At the surface, high pressure will dominate the region through Saturday, while aloft a ridge of high pressure will build over the region. As the upper ridge pushes east Sunday, we will see some increase in cirrus over the region. Leaned toward the low side of dewpoint guidance Saturday as well. Much, if not all, of the area will freeze tonight, and some locations may briefly touch freezing Saturday night.
/Today through Sunday/ A 700mb trough extending across the Deep South continues to maintain a fairly unbroken stratus deck across northeast Louisiana and south-central Arkansas this morning. Overnight low temperatures forecast to fall into the lower to middle 40s. Otherwise, under the influence of surface and upper-level ridging on Sunday, expect mostly sunny skies with high temperatures in the upper 60s to lower 70s.
Dry and mostly clear conditions continue today as ridging aloft prevails. Ridging aloft will is forecast to slide east tonight and Sunday and a trough swings through CA into the southwest U. High temperatures are forecast to be a few degrees warmer Sunday along with southwest winds becoming breezy in some locations in the afternoon, especially across the western CWA.
SHORT TERM (Today through Sunday): High pressure at the surface and aloft remain over the region today with their respective axes tracking east of the coast Sunday.
Winds shift more southeast midday, into the afternoon, helping to hold the warmer temperatures in place. High pressure continues to dominate the pattern, keeping the dry conditions overhead through the weekend and into early next work week. Looking forward to more sunshine today, as clear skies are forecast with temps climbing slightly warmer than yesterday, with highs in the mid to upper 50s. As the High pressure system works towards the east coast today, this will continue the slow clockwise progression of winds. This trend will ramp temperatures through the 40s and 50s during the morning, topping out in the low 60s during the mid-afternoon. Dry weather remains in place as the High pressure remains off the east coast, and dominate upper level ridging continues from the southern Plains through the Ohio Valley.

A mid/upper ridge will build across the central CONUS through Saturday before translating eastward over the Ohio and Tennessee Valley areas on Sunday.
Showers continue through tonight into Saturday morning as short waves rotate around the upper low over Vancouver Island through the region.
314 AM EDT Sat Mar 20 2021 Very quiet weather expected in the short term thanks to Canadian high pressure currently over the Great Lakes region. Current temperatures are in the 30s for many locations, and we're likely to see most spots dip below freezing briefly this morning before sunrise. Afternoon highs are expected to rise into the low and mid 60s with hardly a cloud in the sky. High pressure will slowly drift eastward into the Appalachians through the day, and as it does so, winds will turn ever so slightly from the northeast to the east by tonight. Models remain in very good agreement within this time frame with ridging at the surface and aloft.
130 AM EDT Sat Mar 20 2021 High pressure remains in control through the weekend. Dry weather and clear skies are expected today as high pressure remains in control over the region. Temperatures will be slightly warmer than normal with afternoon highs in the upper 50s to low 60s in the lowlands, and 40s to 50s in the mountains.
an upper level ridge is forecast to shift east across Colorado tonight. an upper level trough is deepen across the western states during the day, with increasing southwesterly flow spreading across Colorado. Mozley The upper trough will translate across the area Saturday night into Sunday, bringing another round of precipitation to southern Colorado. The GFS and EC have come into decent agreement on this movement, so they were the preferred models of the day in regards to this system, sending the trough south of us and putting most of the snow over the mountains. High temps Sunday are expected to be well above freezing over the area, so without proper instability the lower elevations will likely be seeing mostly rain, while the higher elevations will get snow.
419 AM EDT Sat Mar 20 2021 A high pressure area will bring sunny skies this weekend with highs in the 50s today, warming into the 60s Sunday.
Model guidance agrees that the low pressure system to the west will weaken and open into a trough today. Cloud cover and showers will increase in coverage today as the trough approaches. Cooler air in association with today's trough will also cause breezy west and northwest winds for this afternoon. During this evening, the trough is expected to pass to the east and convective allowing models show showers lingering, especially over Lookout Pass and Lolo Pass, so impacts from snow showers cannot be ruled out after sunset.
139 AM EDT Sat Mar 20 2021 High pressure centered over the central Great Lakes will move east across the region over the weekend, reaching the New England coast by Sunday morning.
Excellent flying conditions across South Texas as high pressure remains overhead. /issued 314 AM CDT Sat Mar 20 2021/ SHORT TERM (Today through Sunday): High pressure at the surface and aloft remain over the region today with their respective axes tracking east of the coast Sunday.
501 AM MDT Sat Mar 20 2021 High clouds increased over the forecast area overnight as a deep Pacific mid-level trough made landfall early this morning. Models remained consistent in moving the trough over the Great Basin during the afternoon, driving the surface cold front associated with this system across northeast Utah and extreme northwest Colorado during the latter part of the afternoon.
641 AM EDT Sat Mar 20 2021 High pressure remains in control through the weekend. Dry weather and clear skies are expected today as high pressure remains in control over the region. Temperatures will be slightly warmer than normal with afternoon highs in the upper 50s to low 60s in the lowlands, and 40s to 50s in the mountains.
635 AM CDT Sat Mar 20 2021 For the 12Z TAFs, a surface trof of low pressure will deepen today over eastern CO and eastern NM. /Issued 323 AM CDT Sat Mar 20 2021/ A high pressure ridge will cross over the Panhandles today and bring sunny skies and temps in the 60s and 70s. Sunday will see the ridging aloft move to the east as a trough digs in the western CONUS. At the surface, the low pressure center moves further south. Combine this with the cold front that is extending south of the low in eastern Canada, and this will provide an opportunity for the Panhandles to see showers and isolated thunderstorms.
Data from the Key West morning radiosonde balloon revealed northerly winds in the lower troposphere surmounted by a deep layer of westerlies. A continental anticyclone centered over northern Florida dominates the large-scale weather pattern locally. However, a weak low pressure area has developed along a nearby surface front over the northern Bahmas, supported by strong, modestly cyclonic flow aloft. We adjusted the high temperatures to account for the differing surface wind trajectories (slightly warmer Key Largo-Ocean Reef owing to incoming air rooted in warmer, mainland-heated source air mass).
956 AM EDT Sat Mar 20 2021 High pressure centered over Lake Erie will continue to control the weather over central Indiana for today. Subsidence from the high will keep clear skies in place and light easterly component winds will be the rule. Strong subsidence with high pressure both aloft and at the surface will result in a dry weekend with plenty of sunshine. Early in the forecast period, the ridge axis will be just west of the Mississippi River, gradually shifting directly over Indiana by Sunday. Overnight lows will dip close to the freezing mark tonight.
312 AM MDT Sat Mar 20 2021 Southwest flow aloft will strengthen today as the upper level ridge axis shifts east of the forecast area. For tonight, a short wave and cold front will push east into the area. The cold front will likely arrive by mid to late evening across the northern mountains, bringing a period of moderate to perhaps briefly heavy snowfall.
Sunshine will once again be abundant today with high temperatures reaching the low to mid 60s, with southerly winds increasing a little bit this afternoon. High temperatures will be a degree or two warmer for Sunday, with moisture return increasing out ahead of the next low pressure system entering the western US.
A cooler and drier airmass is moving into the region which will cause morning lows to fall into the mid 40s for coastal areas but interior valleys are set to see lows in the mid 30s. Highs will mostly peak in the upper 50s with a few interior areas breaking into the low 60s. The lowest of the overnight lows will be on higher peaks and withing interior valleys, with sub-freezing temperatures being a high likelihood.
609 AM EDT Sat Mar 20 2021 High pressure centered over the central Great Lakes will move east reaching the New England coast by Sunday morning.
With plenty of sun, we should warm well into the lower 70s through this afternoon. The clear skies/light winds tonight should be very favorable for efficient radiational cooling with lows falling into the lower/mid 40s inland. As such, the main weather story for tomorrow/Sun will be the slightly warmer temperatures with highs climbing into the lower to mid 70s. with lows ranging from the lower to mid 50s across the northern FA and upper 50s to lower 60s for the southern half.
618 AM EDT Sat Mar 20 2021 High pressure anchored over the region will maintain a dry and stable environment, ensuring clear skies this taf period.
20/12Z TAF CYCLE High pressure will remain in control on Saturday bringing clear skies and light winds. Today Through Sunday Night Lighter winds and a mostly clear sky have allowed some areas to see temps drop into the low to mid 30s early this morning. more ridging aloft will be seen. This will result in warmer condtions as there will be a more SRLY component to the SFC flow.
805 AM EDT Sat Mar 20 2021 High pressure remains in control through the weekend. Dry weather and clear skies are expected today as high pressure remains in control over the region. Temperatures will be slightly warmer than normal with afternoon highs in the upper 50s to low 60s in the lowlands, and 40s to 50s in the mountains.
Expect temperatures to rise even further above normal today with upper ridging and strong warm air advection. Hedged on the warmer side of guidance for areas with little to no snow cover. With a strong 850mb jet building in, will likely see gusts peaking near 40 mph, strongest in the elevated terrain near the Buffalo Ridge. Went with the higher end of guidance for winds but still did not quite reach Wind Advisory criteria, so opted not to issue at this time. Overnight, gusty south winds with a strong inversion and increasing cloud cover will keep temperatures on the warmer side.
Overall pattern begins to transition today as the upper ridge shifts to the east and troughing digs into the Rockies, setting the region up for unsettled weather. With the frontal boundary entering the forecast area Sunday morning, expect to see a bit cooler highs Sunday, though still in the 50s, as well as some hit and miss precipitation in the region.
551 AM CDT Sat Mar 20 2021 Broad upper-level ridging continues to expand east across most of the central and eastern CONUS. Winds will veer out of the southeast by the morning with the ridge axis passing over the region, and diurnal mixing will tick winds up slightly. High pressure remains the dominant factor for our weather tonight and tomorrow, but an amplified mid- level trough will advance east and impinge on the longwave ridge tomorrow. The result will be a stronger pressure gradient in the low/mid levels and more amplified southerly flow.
215 AM PDT Sat Mar 20 2021 A few light snow showers will stick around today as the low pressure system exits the region.
1014 AM EDT Sat Mar 20 2021 High pressure centered over the central Great Lakes will move east reaching the New England coast by Sunday morning.
Today, an upper level trof axis enters the United States and begins its move across the west. Ahead of this trof, a southwesterly flow aloft pulls warm, moist air from the southwest, northeastward to The Treasure State. The afore mentioned upper level trof axis moves across the western U. states, quickly, and a weak ridge becomes the dominant feature on Sunday, favoring dry and mild conditions with highs a bit closer to normal in response to a northerly wind shift. Upstream from the ridge, an upper level closed low resides off of the west coast of British Columbia, with a second upper level low located over the Pacific Ocean at about latitude 30N longitude 130W. The next trof is able to enter the area, quickly.
636 AM CDT Sat Mar 20 2021 The main forecast challenges over the next several days include a big temperature swing with a cold front this weekend and a mid- latitude cyclone affecting the Great Plains early week. This setup will lead to even warmer and windier conditions than yesterday.
A passing weather disturbance will deliver windy conditions and cooler temperatures today followed by breezy and even cooler temperatures on Sunday.
Very quiet weather expected in the short term thanks to Canadian high pressure currently over the Great Lakes region. Current temperatures are in the 30s for many locations, and we're likely to see most spots dip below freezing briefly this morning before sunrise. Afternoon highs are expected to rise into the low and mid 60s with hardly a cloud in the sky. High pressure will slowly drift eastward into the Appalachians through the day, and as it does so, winds will turn ever so slightly from the northeast to the east by tonight. Models remain in very good agreement within this time frame with ridging at the surface and aloft.
Nudged this afternoon's high temperatures upward just a notch in the western counties, where some locations will climb into the lower 70s. Cooler readings in the lower to middle 60s will still be the norm across the eastern zones, where a light northeast to east fetch will persist for much of the day.
931 AM EDT Sat Mar 20 2021 All is quiet across our Northwoods this late March Saturday thanks to a large area of strong high pressure centered over the Great Lakes region. Highs today will range from the lower 50s in eastern upper (south winds coming off cold Great Lakes), to well into the 50s and perhaps some lower 60s in nrn lower. Lows tonight will likely not fall out of the low to mid 30s.
Strong subsidence with high pressure both aloft and at the surface will result in a dry weekend with plenty of sunshine. Early in the forecast period, the ridge axis will be just west of the Mississippi River, gradually shifting directly over Indiana by Sunday. Overnight lows will dip close to the freezing mark tonight.
/issued 319 AM CDT Sat Mar 20 2021/ Crisp clear skies overnight across southeast Texas with temperatures falling into the low to mid 40s. low pressure troughs were covering east and west coasts and in the mid section of the country a ridge of high pressure could be found. that will signal the beginnings of the western US coast trough moving eastward with southwest flow developing aloft over the area.
An upper level ridge over the plains this morning will gradually slide east through the day with and upper level trough moving into the region on Sunday. There is good model agreement that an upper level low at 500mb will close off and strengthen as it tracks southeast of our forecast area.
A cold front will push through the area this morning, bringing breezy winds to the region.
503 AM EDT Sat Mar 20 2021 High pressure remains in control through the weekend. Dry weather and clear skies are expected today as high pressure remains in control over the region. Temperatures will be slightly warmer than normal with afternoon highs in the upper 50s to low 60s in the lowlands, and 40s to 50s in the mountains.
531 AM MDT Sat Mar 20 2021 High clouds increased over the forecast area overnight as a deep Pacific mid-level trough made landfall early this morning. Models remained consistent in moving the trough over the Great Basin during the afternoon, driving the surface cold front associated with this system across northeast Utah and extreme northwest Colorado during the latter part of the afternoon.
603 AM EDT Sat Mar 20 2021 A high pressure area will bring sunny skies this weekend with highs in the 50s today, warming into the 60s Sunday.
634 AM EDT Sat Mar 20 2021 [Through 12Z Sunday] Northeast winds 10 to 15 kts and gusting over 20 kts at times today in the wake of a cold frontal passage early this morning. A wedge of high pressure will build down into our area through tonight with an inverted trough developing off the northeast Florida coast. The passage of the front along with limited sunshine should hold max temps only in the lower to mid 60s for most locations.
412 AM CDT Sat Mar 20 2021 An upper level ridge over the plains this morning will gradually slide east through the day with and upper level trough moving into the region on Sunday. There is good model agreement that an upper level low at 500mb will close off and strengthen as it tracks southeast of our forecast area.
625 AM CDT Sat Mar 20 2021 A weak low-level trough across the region will maintain low VFR ceilings across the MLU/ELD terminal sites, possibly extending westward across the SHV/TXK sites through 20/20Z before conditions gradually improve thereafter. /Today through Sunday/ A 700mb trough extending across the Deep South continues to maintain a fairly unbroken stratus deck across northeast Louisiana and south-central Arkansas this morning. Overnight low temperatures forecast to fall into the lower to middle 40s. Otherwise, under the influence of surface and upper-level ridging on Sunday, expect mostly sunny skies with high temperatures in the upper 60s to lower 70s.
Currently watching the speed and timing of the cold front as it crosses the divide. Models depict the cold front and first round of precipitation through the area by late tonight. However, the upper- level trough will continue to provide support for scattered snow showers, especially east of the divide, through the day Sunday. Behind the departing trough, northwest flow sets up and allows for the development of orographic snow showers across the western mountains for an active end to an active period.
Despite the low confidence, included a brief MVFR tempo for both sites. Very quiet weather in the short term as high pressure drifts across the region. Ridging tracks off to the east tonight, allowing return flow to resume and moisture to begin to build back into the Coastal Bend.
253 PM EDT Sat Mar 20 2021 Current surface analysis displays broad area of high pressure centered over the Lower Great Lakes region and expanding across much of the eastern half of the CONUS. Overnight low temperatures are expected to fall into the lower to mid 30s, a touch warmer than this morning but still a bit cooler than normals. Tomorrow, high pressure will continue to slowly glide off to the east, with winds shifting to the southeast throughout the day. Upper level ridging will remain over KY and southern IN Sunday night with plenty of dry air still in place.
/Issued 635 AM CDT Sat Mar 20 2021/ For the 12Z TAFs, a surface trof of low pressure will deepen today over eastern CO and eastern NM. /Issued 323 AM CDT Sat Mar 20 2021/ A high pressure ridge will cross over the Panhandles today and bring sunny skies and temps in the 60s and 70s. Sunday will see the ridging aloft move to the east as a trough digs in the western CONUS. At the surface, the low pressure center moves further south. Combine this with the cold front that is extending south of the low in eastern Canada, and this will provide an opportunity for the Panhandles to see showers and isolated thunderstorms.
but have kept the low pops from generally east and south of KCSG to KAHN tonight into Sunday morning. The trough gradually drifts off the GA coast by late Sunday afternoon.
111 PM EDT Sat Mar 20 2021 All is quiet across our Northwoods this late March Saturday thanks to a large area of strong high pressure centered over the Great Lakes region. Highs today will range from the lower 50s in eastern upper (south winds coming off cold Great Lakes), to well into the 50s and perhaps some lower 60s in nrn lower. Lows tonight will likely not fall out of the low to mid 30s.
All this is due to an upper level trough that will move over the area today.
302 PM CDT Sat Mar 20 2021 Clear skies today with slightly warmer temperatures and breezy conditions as southerly flow reestablishes. The lower humidity and breezy conditions will also increase fire weather concerns today, especially across far northeast Kansas and northwest Missouri where the stronger winds will reside. The low-level jet will weaken near sunrise and winds will slacken before diurnal mixing and more gradient driven winds take over. As the main upper level trough ejects out into the Plains, increasing isentropic lift will allow scattered showers to develop across eastern kansas and gradually spread into western Missouri.
Winds have increased through the day as low pressure deepens in the high plains. The mid level trough this afternoon was located across the western states while a mid level ridge was across the eastern Plains. Tonight through Sunday, the mid level trough will continue to advance eastward into the Rockies with southwest flow across the Plains. Low pressure develops in the lee of the Rockies with a frontal boundary extending northeast into north central Kansas Sunday evening. Tonight the lower boundary layer will remain mixed through the night with lows in the mid 40s forecast with southerly winds of 10 to 25 mph expected with gusts over 30 mph in north central Kansas.
1034 AM CDT Sat Mar 20 2021 An upper trough currently located over the Mid-South will continue to move east this afternoon. Highs should reach into the lower to mid 60s. Temperatures should top out in the lower 60s this afternoon.
Departing high pressure continues to provide an abundance of sunshine, with breezy southerly winds in its wake courtesy of a tightening pressure gradient.
Temps are in the low 60s across the area. In the eastern portions of the area where winds will stay stronger, temperatures will remain warmer for Sunday, with cooler temperatures behind the front.
However, with steady south winds through the night this will keep temps warmer than last night with lows in the middle 30s expected.
Large area of strong high pressure producing mostly sunny skies and quiet wx for the entire Great Lakes region. Surface winds have shifted to the SW in response to high pressure center shifting just east of our state. advecting warmer air into our region. High pressure centered will continue to slowly shift eastward away from our state. Pattern synopsis/forecast: Early Sunday morning, amplified ridging is expected to be positioned across the eastern half of the CONUS with troughing digging across the Intermountain West. Primary focus through early this week will revolve around two separate areas of low pressure - one across northern Canada and another developing lee of the Rockies that's expected to trek northeastward through the Plains into the Upper Mississippi by midweek.
