Monday doesn't look too different, as the center of the area of high pressure over the northern Gulf of Mexico doesn't move much. With a warmer start to the day though, think highs will top out a few degrees warmer in the 73 to 76 degree range in most locations.
Tonight and tomorrow (Monday) morning a cut-off low pressure system will move across the region causing some cooler temperatures and precipitation. As is typical with these cut-off lows, this one is wobbling about in the forecast models even at 24 hours out. The rest of the week will just have intermittent showers with some warmer days in between.
120 PM EDT Sun Apr 4 2021 High pressure is expected to bring seasonable weather over the next couple of days with the next chance of precipitation coming mid week. Tonight, the atmosphere will have a tough time decoupling so winds will help keep the lower levels mixed.
1241 PM EDT Sun Apr 4 2021 High pressure provides dry weather tonight. High pressure will maintain dry weather through tonight. The sky is expected to initially remain mostly clear, but clouds will begin to increase a bit towards morning as a warm front crosses and clouds spill over an upper ridge centered over the Mississippi Valley.

Temps in the low 70s will settle into the mid to upper 60s this evening, then mid to upper 50s overnight. Some normally cooler locations across the interior may realize upper 40s late tonight, while some coastal locations of south Brevard/Treasure Coast will only drop into the low 60s. Dry and a bit warmer as afternoon temps reach the mid 70s along the coast, and upper 70s inland. As high pressure remains nearby, light winds Monday night and clearer skies could allow for temps to drop into the upper 40s to mid 50s. High pressure well offshore the NE FL Coast Mon will flatten through much of the week ahead. Extension of a ridge across N Fl will keep fair conditions with a continued warming trend early-mid week.

1038 PM EDT Sun Apr 4 2021 Currently - A 1025 mb ridge across northern Florida the adjacent Atlantic and Gulf Coast is producing moderate to fresh easterly breezes across the Keys and surrounding waters. Lower level ridging is centered over the Gulf of Mexico, maintaining a massive subsidence inversion based around 825 mb. Short Term Update - Through the overnight period, the high will remain fairly stationary but spread out southwards some. Due to the proximity and shape of the ridge, the source region of our airmass remains well to the north, but considerably modified by a long maritime streamline. A ridge across north Florida will maintain moderate to fresh easterly breezes with a slight downwards trend.
211 PM PDT Sun Apr 4 2021 Dry weather with temperatures trending cooler through Monday, then trending warmer through the rest of the week. A low pressure area over the Pacific Northwest digs southward and moves through Northern California on Monday. The low does not look as moist as earlier model runs but have left a mention of some showers over the Sierra Nevada near the crest for the afternoon.
High clouds are increasing over the area in advance of a small but potent closed upper low that is approaching. This system will bring precip mainly to the higher elevations tonight and tomorrow. Cold front passage Monday morning will bring showers and breezy winds.

High pressure remains entrenched over the northern Gulf of Mexico northward into Alabama and Georgia. Monday doesn't look too different, as the center of the area of high pressure over the northern Gulf of Mexico doesn't move much. With a warmer start to the day though, think highs will top out a few degrees warmer in the 73 to 76 degree range in most locations.
High pressure over the southeast U. Boating conditions will further improve as broad high pressure over the southeast U.
1009 PM EDT Sun Apr 4 2021 High pressure will prevail through mid-week. A cold front will approach the area near the end of the week. High pressure will remain the dominant surface feature over the region tonight. Lows are forecast to range from the low/mid 40s inland to lower 50s at the immediate coast.

Also, while initially light, surface winds will begin to increase over western portions Monday and further increase moisture in the lower levels.
Cool high pressure builds into the region tonight, with clearing skies will lead to chilly temperatures and the possibility of frost Monday morning.
Mainly clear skies will continue tonight with low temps ranging from the low 30s across the norther tier to around 40F in the Hrb/York/Lanc area. Low temps will also be +5-10F warmer across this area.
This will allow for warmer temps along with increasing moisture across the region. do think chances for SHRA/TSRA will increase starting after midnight Tue night as a SFC cold front begins to push towards AR from the west.
High pressure over the southeastern United States will keep sunny skies across the region. With little change in airmass, temperatures will be similar to their values over the last 24 hours, with highs in the mid 70s and lows in the lower 50s. High pressure will remain across the Southeast, allowing for another dry day. As the N MO upper low drifts NE into MI, northern stream energy from British Columbia dives SE and reloads a new closed low over the Midwest by Sat.
Things will dry out briefly later Thu, but a cold front trailing the pre-frontal boundary with move across Thu night into very early Fri, and additional redevelopment is likely as it passes. The cold front will push well south and at this point the midwest upper low will move up into Canada, bringing only weak upper waves across the mid-south.
The system will move east of the state by 12z Monday with a trailing cold front stalling across southern Wisconsin. The front will is expected to lift northward as a warm front.
/Issued 250 PM EDT Sun Apr 4 2021/ High pressure regime continues, need we really say more? Afternoon temperatures continue to increase with each day with low 70s today giving way to highs in the mid to upper 70s tomorrow. Overnight, radiational cooling will once again be strong with clear skies and calm winds but should stay in the low 40s, which mean no more frost or freeze threat.
453 AM EDT Mon Apr 5 2021 Dry conditions expected today and tomorrow with a stubborn area of high pressure over NY and NE PA.
346 AM EDT Mon Apr 5 2021 Dry conditions expected today and tomorrow with a stubborn area of high pressure over NY and NE PA.
A passing dry trough will create the strongest winds of the week on Monday and Tuesday. Beyond warm temperatures again Monday afternoon, there is also the risk for critical fire weather conditions and driving impacts for high profile vehicles Monday afternoon in the high country. A dry trough passing over the Great Basin will tighten the lower and mid-level gradients by Monday morning. There is good operational agreement the trough will pass over northern Arizona by Tuesday morning and produce slightly cooler temperatures for Tuesday.
-- Pretty warm the next few days and an unsettled wet pattern -- Under an amplifying upper level ridge on Tue into Wed, the warm front and most of the precipitation will be north of us, and there is good ensemble support for temperatures well into the 70s.
249 AM MDT Mon Apr 5 2021 Current surface map shows weak low over western North Dakota with cold front advancing through southeast Montana. Cold front moves through northeast Wyoming/northwest South Dakota early this morning. Upper low tracks crosses Rockies into the central plains Tuesday. Thermal profiles support all snow in the higher Black Hills, with snow/rain mix on the plains. The other area that could see a few inches of snow accumulation would be along the Pine Ridge in southwest South Dakota Tuesday night.
Although a broad ridge of high pressure at the surface (currently centered across southern GA/northern FL) will promote radiational cooling once again, boundary layer dewpoints have crept up into the lower 40s for most of the region. Monday doesn't look too different, as the center of the area of high pressure over the northern Gulf of Mexico doesn't move much. With a warmer start to the day though, think highs will top out a few degrees warmer in the 73 to 76 degree range in most locations. Highs despite some scattered cloud cover on Tuesday look even warmer, as upper level ridging builds over the area.
319 AM EDT Mon Apr 5 2021 High pressure centered south of the region will result in a continuation of dry and warm conditions. A slow moving cold front will bring an increasing chance of rain for mid to late week. A surface warm front, as marked by an isobaric trough, slowly drifts north into northern Ohio into the afternoon hours. Aloft, within northwesterly mid-level flow, a weak disturbance will provide sufficient lift to initiate showers and thunderstorms within the lower Great Lakes. Otherwise, southwesterly flow and mostly sunny skies promote another above average day with afternoon temperatures in the low to mid 70s. For Tuesday, surface warm front has shifted further to the north with higher confidence in dry conditions across the forecast area. Mid-level ridge amplifies over the region as a closed low advances east out of the Rockies.
As of 03Z dewpoint recovery is beginning with the passage of the cold front. One more day of dry and unseasonably warm weather is on tap for today across the region thanks to the recent broad ridge of high pressure along and to our south. That ridge of high pressure begins to break down ahead of an approaching cold front beginning later tonight from the west. By Monday morning, a few of those stronger rain showers are expected to reach the ground, focused along and behind the passage of the cold front as it moves through northeast Montana. The low pressure trough responsible for the cold front stretches out and weakens by Monday afternoon.
This southwesterly flow in the low levels will continue to work to bring in even more humid conditions today, as dew points should soar to around 50 for a good chunk of the area (especially west) by the end of the day. There will be more cloudiness today as the low levels moisten up and this trend will continue into Tuesday.
Surface ridging and dry west to northwest flow aloft will produce another quiet night across the Tennessee valley and southern Appalachians. Some return southwest flow in the boundary layer will allow for mild temperatures across the ridge tops then the lower valleys. High pressure will shift SE today with a clear sky and light WSW/SW winds across the area. High clouds approach the area late in the period ahead of troughing across the Central CONUS.

Temps for this afternoon expected to reach into the mid to upper 70s, with tomorrow flirting with temps into the low 80s over central GA.
1153 PM CDT Sun Apr 4 2021 06Z TAFS VFR conditions will prevail through the period as high pressure over the southeastern U.
Trend continues into mid week with temps warming into the mid/upper 80s for afternoon highs with overnight lows in the mid 50s/lower 60s, further warming with highs in the mid 80s/around 90 late week with lows in the low/mid 60s.
241 AM EDT Mon Apr 5 2021 Dry weather continues with high pressure into Monday. During this period, an upper low will spin offshore of New England, while ridging very slowly moves eastward into the Ohio Valley.
Low temperatures through the period will stay relatively mild getting down into the low to mid 50s.
116 AM EDT Mon Apr 5 2021 Dry weather continues into Monday as high pressure remains in place. Seasonable weather is expected through Monday night with high pressure in place. Weak high pressure to our north will keep light northerly flow in place on Tuesday.
118 AM EDT Mon Apr 5 2021 High pressure centered south of the region will result in a continuation of dry and warm conditions. A slow moving cold front will bring an increasing chance of rain for mid to late week. Otherwise, skies will be mainly clear with temperatures slightly warmer than today. Moist pattern then develops in the southerly flow ahead of a slow moving low pressure system advancing from the west.
The persistent, east-west oriented area of high pressure centered over north Florida and the Gulf coast region to well into the Western Atlantic Ocean today, will slowly drop equatorward and weaken over the Florida Peninsula and the adjacent Atlantic and Gulf waters.
Large scale lift is probable given increasingly diffluent upper flow ahead of approaching upper low, but depth/quality of moisture is a bit weak.
Upper level ridging continues to nose in from the west today. Upper level ridging continues to build overhead through Tuesday resulting in another idyllic day across southern Indiana and central Kentucky.
332 AM EDT Mon Apr 5 2021 High pressure will prevail through mid-week. A cold front will approach the area near the end of the week. At the surface, high pressure will be centered south of the forecast area which will result in westerly flow this morning. Tonight: The tranquil pattern will persist as high pressure remains the primary weather feature. Inland locations will likely dip in to the upper 40s while the coastal corridor falls into the low to mid 50s.
It has been a very warm Easter with highs reaching the lower to mid 80s today. And humidity was down into the lower 20% range across south central NE near the KS border, and while winds have been gusty 25-30 mph, probably just short of red flag conditions there. Chances overnight will only be about 20% within a confined corridor along the nose of the low level jet. This will again help to boost temps into the lower 80s for most areas. This brings another chance of showers and storms to the area, but mostly to northeast NE, and then along an advancing cold front moving into the area. We'll see rain chances increase through the day Tuesday as we begin to experience increased forcing for ascent due to the diffluent flow aloft associated with the closed upper low across the Rockies.
Meanwhile, large upper trough moving through the Pacific northwest will cause pressure falls through the high Plains, tightening the pressure gradient and increasing south winds across the area. Although cloud cover may keep portions of southeast Oklahoma in the 70s today, much of the remainder of the state and western north Texas will climb into the low to mid 80s this afternoon.
our next low pressure system moving onshore. with low pressure analyzed near Spokane. Trailing cold front into western Oregon into extreme northern California. More to speak to as we enter the work week as an upper level trough drops out of the Pacific Northwest and dives just south of the WY-CO border. The upper closed low will slide across the region Tuesday, with better chances for precip, though still light, and thunderstorms once again. By Tuesday night, all locations will drop into the low 30s/upper 20s, and with ongoing precip, looks like most locations will see a dusting of snow. Expect about 1-2 inches across the highest mountain elevations.
