High clouds have spread ahead of that wave and they will continue to increase into tonight so lows will be warmer that last night. Conditions will be windy in the high elevations all day and during the afternoon deep mixing will allow gusty winds to reach the valleys especially in southwest Colorado and southeast Utah.
Temperatures have been much cooler across the far north and northeast CWA with early afternoon values only in the low to mid 40s. The remaining snowpack across the north and a cooler SSE wind trajectory, along with a veil of cirrus clouds overhead, has helped to hold temps down. Mild temperatures are expected, staying above freezing for lows (mid 30s to mid 40s).
845 AM MST Sun Mar 7 2021 The forecast period starts out with a ridge over the Central High Plains and northwest flow aloft over the Tri-State area. Average high temperatures for this time of year generally range from the low to mid-50s. Monday afternoon, the ridge moves to the east with the Tri-State area coming under southwest flow aloft. A lee trough is expected to develop over Eastern Colorado through the day with a tightening pressure gradient over Northwestern Kansas.
Water vapour matinee had low amplitude upper ridge building into the northern plains. Main forecast concern is upper low spinning off BC. Surface pressure gradient ahead of low fairly tight so breezy/windy southerly winds foreseen, popping thermal ridge. Trailing cold front enters CWA Monday night.
High pressure will continue to move east of the area with return flow setting up, allowing for a gradual uptick in surface dew points, and SSW winds. Even the lower CONSMOS wasn't low enough today. Went with the lower CONSMOS again.
220 PM EST Sun Mar 7 2021 Chilly high pressure will extend across the central Appalachians and southern mid Atlantic through Monday.
Highs should be around 50 north to the lower 60s south. The cold front is now almost entirely through the forecast area, with only Oakes still reporting southwest winds. The cold front is now approaching the eastern third of third of the state and winds have turned westerly behind it as expected. At the surface, a cold front (really more of a cool front) was located over central North Dakota early this morning. Today will generally be a bit cooler, but less cloud cover may mean that a few areas could see temperatures (especially across the south) a bit warmer than yesterday. Temperatures will rebound on Monday as broad low amplitude ridging builds in. Increasing cloud cover is also likely, as flow turns southwest aloft in advance of a deepening west coast trough.
Dewpoints were in the lower teens across the Bluegrass region while dewpoints were in the upper 20s along and west of I-65. The low dewpoints out in the Bluegrass region are producing low relative humidity values which could be conductive for a quick spread of any wild fire or prescribed burn. Areas east of I-65 could be near freezing by midnight with good radiational cooling expected. Highs tomorrow will range from the lower 60s in the Bluegrass with mid-upper 60s in the remainder of the area.
105 PM EST Sun Mar 7 2021 High pressure through the middle of this week with a warming trend. A high pressure system will provide dry weather for tonight and Monday.
With the dry air mass in place, will hedge lows toward the lower end of guidance to expand diurnal range.
1244 PM EST Sun Mar 7 2021 High pressure in the area through the middle of this week in a warming trend.
Previous discussion: Positively tilted upper trough will move off the coast this afternoon. Although a robust short wave trough will move through the region, moisture will be quite limited. Strong pressure ridge will build southeast from the Tennessee Valley. Strongest advection in the Pee Dee as trough moves east. Expect temperatures a few degrees warmer than yesterday mainly across the CSRA.
1121 AM CST Sun Mar 7 2021 VFR conditions are expected through the period as high pressure continues to dominate the weather pattern. Model forecasts continue to run a little cooler than what is actually being seen and will go a few degrees above guidance. High pressure, both aloft and on the surface will dominate through the period with dry conditions expected. The upper ridge will crest over the area on Monday with low level southerly flow strengthening underneath it just a bit. The result will be highs in the lower to mid 60s today with upper 60s to lower 70s expected on Monday.
This trend of warmer and increasingly above normal temperatures will only continue as we begin the new work week after one more night of rather chilly temperatures. Sunny skies will also continue for one more day before clouds begin to increase on Monday night with temperatures about 10 degrees warmer by comparison tomorrow night compared to tonight.
500 PM CST Sun Mar 7 2021 Despite the fact that a weak cold front will pass through the area late tonight and Monday morning, spring continues to make its presence known with above normal temperatures.
However, for Monday night, lows should be a few degrees warmer ranging between the mid 50s to lower 60s. A weak inverted trough at the surface is expected to trek west across the Gulf tonight, reaching the Middle Texas Coast Monday, bringing a bit more moisture with it along with a less than 20 percent chance for showers across the Gulf waters and possibly right near the coast through Monday night.
737 PM EST Sun Mar 7 2021 High pressure through the middle of this week with a warming trend. However, don't think this will have a big influence on lows so still expecting overnight lows in the low 20s across the lowlands and teens in the mountains. A high pressure system will provide dry weather for tonight and Monday.
236 PM MST Sun Mar 7 2021 Subsident flow under an upper level ridge has been in place today and will continue to be tonight. During the day tomorrow, a weak trough that is associated with the high clouds currently streaming onto the southern California coast will move across Colorado. This trough does not have much cold air aloft or QG ascent associated with it so it is not expected to bring precipitation to the area. It will bring high level cloudiness to the majority of our CWA for much of the day keeping high temperatures close to the same as today despite the warmer 700 mb temperatures.
Center of surface anticyclone has become positioned this afternoon in a lake aggregate fashion over the northern Lake Huron basin. Surface warm front/warm sector is shown to push eastward across all of the area between 9- 12Z with a quasi-stationary front developing along the northern flank of the warm sector across northern Lower Peninsula. The HRRR remains much warmer across the Tri Cities and does not support the same frontal behavior through much of the afternoon.
522 PM CST Sun Mar 7 2021 Dry conditions and warmer than normal temperatures are expected across the area for the beginning of the new week.
Winds will decouple with sunset this evening and weak high pressure will move across the northern plains overnight with light winds and clear skies. Lows tonight will be in the upper 20s to near 30 in the south perhaps a bit cooler where some snowpack still exists. The March 8th high temp records are very much in reach, much lower than the low 60s of the past couple days as the record at Fargo is 54F from 1911. With winds staying up temps again will be warm and most likely above freezing all night Monday.
VFR conditions and light winds as high pressure dominates the forecast for the rest of this week.
955 PM EST Sun Mar 7 2021 Chilly high pressure will extend over the Eastern United States through Monday.
552 PM EST Sun Mar 7 2021 High pressure through the middle of this week with a warming trend. A high pressure system will provide dry weather for tonight and Monday.
800 PM EST Sun Mar 7 2021 High pressure ridging in from the north will allow for some cooler and drier air to filter into the region overnight. Strong high pressure building in from the north will produce gusty northeast winds through late Monday morning.
We can expect to see winds start to die off after sunset as we lose daytime mixing, but also as a sfc trof makes its way across the area into tonight. Couple this with ridging aloft and and we have another good set up for warm temperatures tomorrow, a few degrees warmer than today. Winds will also be rather breezy again tomorrow as we maintain a relatively tight sfc pressure gradient ahead of a midlevel and subsequent sfc trof expected to roll off the Rockies.
822 PM EST Sun Mar 7 2021 High pressure will settle in across the area through Monday, then move off the coast by the middle of the week. As of 610 PM: Latest observations indicate temperatures across the forecast area ranged in the low to mid 50s with dewpoint depressions around 35 degrees. Previous Discussion: The rest of the afternoon will be sunny with gusty northerly winds as high pressure builds into the region and low pressure shifts further east across the Atlantic.
The ridge will continue to shift to the east, keeping return flow in place and bringing a gradual return of low level moisture to the area.
High pressure and warm temperatures will give way to an area of low pressure to our northwest this week. High pressure will shift a little further eastward as a strong low digs down the coast over the next several days.
/issued 300 PM CST Sun Mar 7 2021/ Progressive upper level high pressure ridge will pass east later tonight followed by increasing southwest flow aloft. Also expecting a very modest increase in low level moisture to continue tonight into Monday with surface dewpoints in the lower to middle 40s spreading across much of the area although morning stratus signals for early Monday still look weak. Temperatures expected to be milder tonight and a little warmer Monday.
Surface winds tonight will veer to the east and southeast, and this should help to keep lows above freezing in the mid 30s. A warm thermal ridge at 850mb will be in place Monday morning, which will build eastward and mix down to the surface by afternoon. A south southeast wind will increase to 15 to 30 mph by afternoon with warm afternoon highs in the low to mid 70s. Expecting a pretty strong inversion however, for lows in the low to mid 30s west, to near 45 far eastern areas.
625 PM EST Sun Mar 7 2021 High pressure remains over the area through much of this week. High pres will be ridging into the region overnight. Winds become calm after sunset, and with clr skies and low TD's, strong radiational cooling is expected again, leading to lows in the mid/upr 20s away from the coast, to the low/mid 30s immediate coast. Mostly dry weather expected with high pressure dominating through the period.
Downstream from the low, high level cloudiness was spreading east across NWRN CA.
A broad area of high pressure that extends from southern Canada into Texas is the main weather feature. You can see the circulation around the the high at sfc from fires that are active from Georgia to Texas into Oklahoma on Vsby stlt this aftn. Vsby stlt is also picking up a large cloud field that is moving up from Mexico into deep south Texas around the backside of the high.
This high pressure ridge will continue the dry weather and clear skies through tonight and tomorrow. Tomorrow will also be warmer, and temps reflect the slow warming trend. Given the RHs today dropping to the lower 20s/teens.
/Issued 230 PM EST Sun Mar 7 2021/ The short term period will be ridge-dominated, with large-scale subsidence bringing dry conditions to north and central Georgia. At the upper levels today, the CWA is sandwiched between an exiting longwave trough to the east and a broad ridge building into the central portion of country. Tomorrow, the upper-level ridge axis will shift further east, while at the surface, the high pressure center will shift over the southern Appalachians. Highs tomorrow will generally be several degrees warmer than today --- in the mid- to upper 60s.
Upper level ridging is starting to take hold over the southeastern CONUS as an upper trough progresses over the east coast. This ridge will maintain its hold over the region through the near term period. At the surface, high pressure will settle directly over the southeast today. Much like today, minimum relative humidity values are therefore expected to be in the teens over inland areas and in the lower to mid 20 percent range near the coast on Monday. Current temperatures across the local area are generally in the lower to upper 60s. It will then be a bit warmer on Monday, as highs are forecast to be in the upper 60s at the coast and in the lower 70s inland.
A strong high pressure system is poised to build into Florida overnight and through Mon. Overnight temperatures will be in the M-U40s across the north and across inland counties, perhaps a few L40s in normally cooler locales, and generally 50s from the south Brevard coast southward through Martin County.
830 PM EST Sun Mar 7 2021 A strong area of Canadian high pressure will continue to expand across the area through Monday before drifting offshore during the middle of the week. A cold front is expected to slowly approach from the north toward the end of the week. High pressure is moving directly overhead tonight. The stubborn upper trough that has influenced our weather over the past several days is finally pressing offshore tonight. High pressure at the surface will follow within the zone of subsidence behind it.
615 PM EST Sun Mar 7 2021 Chilly high pressure will extend across the central Appalachians and southern mid Atlantic through Monday.
540 PM CST Sun Mar 7 2021 A warming trend will continue with an upper level ridge over the region coupled with increasing south-southwesterly surface/low level flow. Not only will the daytime highs become warmer, but the nighttime lows will also become quite mild due to rising surface dew points along with more nocturnal boundary layer mixing.
944 PM EST Sun Mar 7 2021 High pressure remains over the area through much of this week. High pres will be ridging into the region overnight. Winds become calm after sunset, and with clr skies and low TD's, strong radiational cooling is expected again, leading to lows in the mid/upr 20s away from the coast, to the low/mid 30s immediate coast. Mostly dry weather expected with high pressure dominating through the period.
217 PM MST Sun Mar 7 2021 Temperatures are running about 5 degrees cooler today then they were yesterday. Other than that, not much effect from the previous cold front.
611 PM EST Sun Mar 7 2021 High pressure will settle in across the area through Monday, then move off the coast by the middle of the week. As of 610 PM: Latest observations indicate temperatures across the forecast area ranged in the low to mid 50s with dewpoint depressions around 35 degrees. Previous Discussion: The rest of the afternoon will be sunny with gusty northerly winds as high pressure builds into the region and low pressure shifts further east across the Atlantic.
956 PM EST Sun Mar 7 2021 We'll have another quiet, cool night with high pressure firmly in control. Dewpoints were in the lower teens across the Bluegrass region while dewpoints were in the upper 20s along and west of I-65. The low dewpoints out in the Bluegrass region are producing low relative humidity values which could be conductive for a quick spread of any wild fire or prescribed burn. Areas east of I-65 could be near freezing by midnight with good radiational cooling expected. Highs tomorrow will range from the lower 60s in the Bluegrass with mid-upper 60s in the remainder of the area.
In the end, morning lows will fall to around freezing areawide thanks to ideal radiational cooling tonight. A few sheltered valley locations may see some freezing fog in the morning, mainly in the Paint Rock Valley in Wrn Jackson County, as well as in a few spots along the TN River. Deterministic model runs continue to struggle in representing warmer temperatures, compared to their ensemble counterparts, and therefore temperatures through the forecast period have been raised a few degrees above suggested guidance. The 850 mb ridge settles over the Deep South, so we shouldn't get a "surprise" breeze from increased mixing, like we did today.
1051 PM CST Sun Mar 7 2021 A warming trend will continue with an upper level ridge over the region coupled with increasing south-southwesterly surface/low level flow. Not only will the daytime highs become warmer, but the nighttime lows will also become quite mild due to rising surface dew points along with more nocturnal boundary layer mixing.
131 AM EST Mon Mar 8 2021 Dry high pressure through the middle of this week with a warming trend.
134 AM EST Mon Mar 8 2021 An exiting longwave trough along the North American East Coast will allow high pressure to build along the Appalachians and Mid Atlantic states. This high pressure system will expand to cover the entire Southeast continue through midweek until it slowly drifts out to sea. This is in response to a longwave trough digs into the West Coast lowering pressures over the Plains. The positively tilted trough in the west slowly drifts east and develops into a Rex Block over the southwest states by the weekend. Winds will veer and lighten today, warmer air and higher moisture will slowly return.
Pressure ridge over the area will move to the coast tonight.
259 AM CST Mon Mar 8 2021 Water vapor imagery depicts a mid-level shrtwv trof INVOF SOCAL with an extremely long fetch of Pacific mid/upper-level mstr entrained within the sw flow aloft. At times minor mid-level jetlets and assocd shrtwv trofs will move thru the sw flow enhancing the lee trof, low-level thermal ridge, and clouds. As a result the general sensible wx will be warmer, drier, and windier through at least Thu, including episodes of high winds in the GDP Mtns (high wind watch/warning likely). There is now better deterministic agreement that a Pacific front will finally move across on Sat bringing a bout of strong dry winds and cooler temps, precip chances are expected to trend down Sat-Sun but there could be wrap around -SHRA.
1220 AM EST Mon Mar 8 2021 High pressure remains over the area through much of this week. High pres will be ridging into the region overnight. Winds become calm after sunset, and with clr skies and low TD's, strong radiational cooling is expected again, leading to lows in the mid/upr 20s away from the coast, to the low/mid 30s immediate coast. Mostly dry weather expected with high pressure dominating through the period.
/issued 958 PM CST Sun Mar 7 2021/ Another quiet night is expected across the forecast area amid dry high pressure. A broad area of high pressure that extends from southern Canada into Texas is the main weather feature. You can see the circulation around the the high at sfc from fires that are active from Georgia to Texas into Oklahoma on Vsby stlt this aftn. Vsby stlt is also picking up a large cloud field that is moving up from Mexico into deep south Texas around the backside of the high.
High pressure will shift southeast of the Appalachians today so expect SW winds to return to KCHA and KTYS during the late morning to early afternoon timeframe.

352 AM EST Mon Mar 8 2021 High pressure traveling from Southeast Ohio to the Carolinas will provide dry weather and milder temperatures today.
1115 PM EST Sun Mar 7 2021 We'll have another quiet, cool night with high pressure firmly in control. Dewpoints were in the lower teens across the Bluegrass region while dewpoints were in the upper 20s along and west of I-65. The low dewpoints out in the Bluegrass region are producing low relative humidity values which could be conductive for a quick spread of any wild fire or prescribed burn. Areas east of I-65 could be near freezing by midnight with good radiational cooling expected. Highs tomorrow will range from the lower 60s in the Bluegrass with mid-upper 60s in the remainder of the area.
The upper level ridge will shift further east overnight with an increasing southwesterly flow aloft. Subsident flow under an upper level ridge has been in place today and will continue to be tonight. During the day tomorrow, a weak trough that is associated with the high clouds currently streaming onto the southern California coast will move across Colorado. This trough does not have much cold air aloft or QG ascent associated with it so it is not expected to bring precipitation to the area. It will bring high level cloudiness to the majority of our CWA for much of the day keeping high temperatures close to the same as today despite the warmer 700 mb temperatures.
330 AM EST Mon Mar 8 2021 It will be warm and breezy today with highs into the lower to middle 60s this afternoon.
242 AM CST Mon Mar 8 2021 Chamber of Commerce weather weather will continue across the Mid- South today as a ridge builds over the central CONUS. The trough over the East Coast will lift out today but a strong trough will dig into the western CONUS through midweek. For our neck of the woods, we're looking at conditions similar to what we saw yesterday, albeit 3-5 degrees warmer. As the trough digs over the west the next few days, a corresponding ridge will build over the east. This will result in southwest flow aloft that will increase through late week as a strong subtropical jet rounds the base of the trough and propagates over the Plains.
1248 AM EST Mon Mar 8 2021 High pressure will settle in across the area through Monday, then move off the coast by the middle of the week. Temperatures will fall to as cold as 27-28F degrees along the northwest tier, the upper 20s and lower 30s most elsewhere near and west of US-17, while barrier islands, downtown Charleston and near Lake Moultrie will be several degrees warmer.
In the low levels, a lee trough currently analyzed over the High Plains will deepen in place with winds increasing from the south. Similar to past days, we will stay on the high side of guidance for afternoon temperatures, though an earlier arrival of the above-mentioned clouds could have an impact on peak readings.
A few locales could briefly drop to the freezing mark near daybreak. 850mb ridge along the northern Gulf coast will shift eastward and settle over the area tonight. Under sunny skies, temperatures will warm into mid to upper 60s to near 70 degrees across the interior and the lower 60s towards the beaches. Overnight lows will be cold once again, with lows in the low to mid 30s across interior southeast Georgia and the Suwannee Valley, and the 40s to lower 50s elsewhere.
1049 PM EST Sun Mar 7 2021 High pressure will settle in across the area through Monday, then move off the coast by the middle of the week. As of 610 PM: Latest observations indicate temperatures across the forecast area ranged in the low to mid 50s with dewpoint depressions around 35 degrees. Previous Discussion: The rest of the afternoon will be sunny with gusty northerly winds as high pressure builds into the region and low pressure shifts further east across the Atlantic.
