655 PM EDT Sun Apr 27 2025 High pressure moves overhead with sunny skies and warm temperatures on Monday.
A weak and split ridge stretching across the Florida Peninsula is still managing to maintain gentle to moderate northeast to easterly breezes across the Keys and surrounding waters this evening. Mid level ridging is aligned across Florida, while the axis of an upper trough is aligned over the eastern Bahamas and Cuba. Through the overnight period, the previously mentioned ridge will begin to be reinforced by a large high building in from the eastern United States. Stable conditions will remain due to dominant ridging. A split remnant ridge across the Florida Peninsula is resulting in gentle to moderate northeast to easterly breezes across the Keys. The ridge will also begin to be reinforced by an expansive high spreading out across the eastern United States.
540 PM EDT Sun Apr 27 2025 Dry and slightly cooler high pressure continues through Monday.
Otherwise, expect a quiet, warm, and muggy night tonight and again on Monday night with overnight lows in the lower to mid 70s. Moderate winds and elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
Upper air observations have shown some increasing heights across the Gulf, suggesting that the high pressure draped over the region is strengthening. As the high pressure very slowly amplifies and tracks eastward across the country, the pattern should remain dry. Will go ahead and keep the overarching theme of slight chances of showers, but these may need to be adjusted throughout the week while we observe how the high actually evolves. From synopsis, gentle to moderate breezes today will freshen tonight as high pressure over the southeastern U.

Latest satellite imagery shows our region underneath the back side of an upper-level low pressure system that has moved east of our region into the Great Basin. Otherwise, low and mid- level clouds will persist today with cooler than average temperatures.
Mid level high pressure is centered across Mexico with a ridge extending to the north. The high center should shift eastward into the western Gulf with the ridge building northeast into the eastern Gulf states through Tuesday. High pressure is currently across the central Great Lakes. This high will drop southeast this morning and then move off the Delmarva coast by later today. A wedge will build in from the northeast as the high moves offshore.
207 AM EDT Mon Apr 28 2025 Dry, sunny, and much warmer today. Abundant sunshine and developing light S'ly breezes during the day will allow for highs to surge back above normal, into the lower 80s for most lower elevations, with mid-60s to 70s in the mountains. The gentle S'ly breezes will persist overnight, keeping temperatures on the mild side for most of the area, with in the upper 40s for the highest peaks, and the mid to upper 50s for most of the lower elevations. Temperatures will rebound to above normal as area remains in the warm sector of an approaching low pressure system, that will move east across Canada, and its associated surface cold front.

High temperatures today and Tuesday will range from the 80s near the coast to the low to mid 90s along and west of the I-69E corridor. Lows tonight will fall into the low to mid 70s with increasing clouds. Elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
- A cold front moves across central and eastern South Dakota this afternoon. Guidance from the CAMs in the morning shows little overall development however, so while the risk is there, it seems that warmer air aloft will help limit the potential through the morning hours. Another cold front is expected to move across the forecast area in the afternoon, and post-frontal showers and storms will ensue. As the upper level trough progresses eastward, the forecast area will enter a fairly quiet period (with the exception of some light showers midweek).
High pressure will build over the region today with clear skies and warm air advection. There remains some timing concerns as the front moves east so have kept higher POPS near Jackson to account for afternoon convection if the cold front lingers.
Under generally sunny skies, high temperatures later today should rise into the low/mid 80s.
223 AM MDT Mon Apr 28 2025 - Today will be windy and cooler with scattered to numerous showers and scattered thunderstorms in the wake of a passing cold front. - Tuesday will be warmer for most locations, along with drier and less windy conditions.
One of the reasons for the higher temps is there will very little in the way of rain around the area for the next few days.
959 AM EDT Mon Apr 28 2025 Dry high pressure remains in place today.
Dry conditions, with daily breeziness in higher terrain areas, through the week will precede another weather disturbance that is anticipated to bring more elevated winds and cooler temperatures to the region this weekend. This low is part of a longwave trough that's positively tilted across the Desert Southwest, resulting in below normal temperatures for the region today. Near seasonable temperatures will develop by tomorrow as this longwave trough lingers, but will weaken going into the middle of the week.

Lows tonight will fall into the low to mid 70s with increasing clouds. Elevated seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches.
Over the Southeast, the upper ridge remains strong into mid week. The combination of subsidence and tilting of the upper ridge will move dry air in the mid and upper levels over the Lower Mississippi River Valley and western portions of the Southeast Monday night on, even as onshore flow in the lower levels keeps moisture levels in the lower levels high (with precipitable h20 values dropping from around 1. Subsidence from the upper ridge will keep temperatures well above seasonal norms through the Near Term.

Slight change in the weather going into this weekend with cooler temps and damp conditions.
148 PM PDT Mon Apr 28 2025 Dry and warmer weather, with marine layer low clouds each night and morning in the coastal areas and valleys, will continue this week. Cooler, cloudier, breezier, and probably wetter weather is expected this weekend as a low pressure trough arrives. WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO The clouds over the coastal basin are slowly and gradually dissipating under the spring sunshine this afternoon as a low pressure trough takes its sweet time exiting our region. A weak high pressure ridge aloft will bring warmer and sunnier weather Tuesday.
1221 PM CDT Mon Apr 28 2025 (Today through Tuesday) Deep South Texas will remain under the influence of high pressure at the surface and aloft. High temperatures today and Tuesday will range from the 80s near the coast to the low to mid 90s along and west of the I-69E corridor.

312 PM EDT Mon Apr 28 2025 Canadian high pressure will build across and offshore the Middle Atlantic through tonight, then drift toward Bermuda through mid to late week. Otherwise, low-level thicknesses will rise some early Tuesday morning, and given the weak sly flow, expect a bit warmer overnight lows tonight in the upper 40s to lower 50s. By Tuesday afternoon, sswly flow will organize a bit bumping temperatures up into the lower to mid 80s. Moisture return will be limited, however, as dew points mix out into the lower to mid 50s (highest west) Tuesday afternoon. The only caveat is that some of the high-res guidance suggests some upstream convection may traverse the mountains and hold together long enough to drop a few hundreds over the Triad.

353 PM EDT Mon Apr 28 2025 High pressure will slide off of the North Carolina coast tonight into Tuesday, settling between the Carolinas and Bermuda through the remainder of the week.
Upper air models show the upper low over the central ND/SD border, with a positively tilted trough stretching down into the four corners region. The highest elevation Black Hills areas could see an inch or two of snow accumulation through the evening.
- Cooler behind a cold front Tuesday afternoon (mid to upper 60s), with moderating temperatures generally in the 70s for the remainder of the forecast period.
(Tonight) Under mostly clear skies temps have risen into the low to mid 80s across the area. High pressure will continue to dominate through the night promoting clear skies and continues SE flow bringing in warm air from the Gulf Stream.
Strong moisture advection will create a much more unstable atmosphere as a warm front currently draped across southwest WI moves north and east. As the event progresses and a cold front starts to push into the western part of the forecast area storms are forecast to grow upscale into a QLCS. Behind the cold front there may be some lingering thunderstorms Tuesday morning, but the risk for any severe storms at that time will be low. Tuesday Night Through Monday Tuesday-Monday: Cooler conditions are expected on Tuesday in the wake of the surface cold front as Canadian high pressure builds into the area.
1131 AM EDT Mon Apr 28 2025 Drier and somewhat cooler air will remain over the area today.
1125 AM MDT Mon Apr 28 2025 KEY MESSAGES: - A trough Tuesday will bring another round of rain showers to the region.
Water vapor imagery shows a closed low over/near the Great Basin. By late tonight, the cold front will catch up with the dryline, and will likely generate a broken line of showers and storms that should impact the KC Metro terminals between roughly 6z and 9z early Tuesday morning.
Easterly winds are supporting a faint cloud line training west of the Lower Keys, but those clouds will dissipate overnight. Zooming out to country-wide weather, a 1028 mb high building off the Eastern Seaboard will both tighten the pressure gradient and push a shallow plume of moisture associated with a decaying cold front across South Florida and the Keys tomorrow. Note, the Upper Keys are more likely to see rainfall tomorrow than the Lower and Middle Keys. Following the moisture boundary passage tomorrow night, ridging conditions will prevail across South Florida.
Issued by National Weather Service Gray ME 424 PM EDT Mon Apr 28 2025 High pressure will crest south of the area tonight.
The cold front that is currently from Bemidji, MN to Gwinner, ND will push the rest of the way through our forecast area this evening.
(This evening through Tuesday Night) Quiet conditions across the forecast area today, as upper ridging remains over the region. By tonight, the ridge will start to slowly push eastward. At the same time, a closed upper level trough will be digging through the Great Basin Region of the Rockies into the Four Corners Region of the SW CONUS. Ahead of trough and behind the ridge, flow aloft will become southwesterly. Dry weather should return for most of area on Tuesday, as the upper ridging will still try to hang on across the region. But, as we move throughout the day, the ridge will shift east enough to allow southwest flow to setup areawide.
In the wake of this system, high pressure will slide into the forecast area tonight. However, it wouldnât be entirely surprising if a few locations in our traditionally cooler spots drop into the teens.
A weak cold front to our north will be slowly pushing over us during the next two days as it dissipates. This weak cold front will help to increase our moisture over the area.
