836 AM EDT Mon Apr 14 2025 High pressure will continue to move eastward today from the Florida Peninsula into the Western Atlantic Waters. The dry air will also allow for the relative humidity to fall into the lower to mid 30s over the interior areas this afternoon while the metro areas will see humidities fall down into the 40s. As the trough advects through these areas, an attendant frontal boundary will push southeastwards although it is looking to be more of a diffuse boundary as it advects southeastward and is likely not going to arrive into South Florida until further in the middle of the week. High temperatures for today and tomorrow are expected mostly in the mid to upper 80s with only the immediate coastlines experiencing highs in the low 80s.
High pressure aloft and a thermal trough at the surface will keep area skies clear today, and push afternoon temperatures even warmer compared to yesterday, reaching highs more typical of early June than mid April. Tuesday, the upper ridge and surface thermal trough will shift east resulting in slight cooling west of the Cascades. At the same time, we'll be sandwiched in between a weak approaching upper trough from the west and a cut off upper low off the California coast. Mid level moisture will move up from the south ahead of the upper low, providing enough fuel for convective showers in northern California mid to late Tuesday afternoon and evening.
The other area of much lighter precipitation is falling where it is warmer, so it is falling as very light rain. Low pressure is over western Lake Superior at 08z and will track northeast today. Area to be in northwest flow aloft this week and weather more tied to development of 500 mb trough in central Canada Wed-Thu and then how much moisture is brought up from the south with the southern stream jet over the southern Rockies into the central Plains. GFS ensembles are a bit stronger with 500 mb ridge over Michigan vs ECMWF/Canadian global and has higher pops in our forecast.
502 AM EDT Mon Apr 14 2025 (Today through Tuesday) Key messages: - Warmer temperatures today. - Cooler temperatures on Tuesday. Temperatures will continue to warm, with highs ranging from the mid 70s in the NE mountains to the lower to mid 80s elsewhere. A weak cold front will approach the area from the NW this evening, with isolated to low end scattered showers moving into the County Warning Area (CWA) before weakening. The biggest impact of the cold front will be to knock temperatures back down to near or slightly below normal. Minimum relative humidity values will range from 22 to 30 percent this afternoon, with the lowest values generally SE of Macon. Wind gusts near 35 mph will be possible in the higher elevations in N GA.
Any of our neighbors sensitive to relatively cooler temperatures, including this forecaster, may have noticed how cool it has been outside. As of 430 AM, air temperature observations read mostly in the lower 70s, and dew point temperatures are in the lower 60s. This is thanks to deep high pressure aloft that is passing across the southeastern U. These comfortable, and almost brag worthy, conditions will continue as the high track eastward and out over the North Atlantic over the coming days. We do still have our eyes on the end of the week as guidance continues to suggest that a trough over the eastern U. From synopsis, high pressure will settle across the southeastern U.

A Chamber of Commerce day is in store for Tuesday with high pressure settling overhead.
VFR conditions will prevail through the TAF period as high pressure remains in control and very dry air persists in the boundary layer. High pressure aloft and a thermal trough at the surface will keep area skies clear today, and push afternoon temperatures even warmer compared to yesterday, reaching highs more typical of early June than mid April. Tuesday, the upper ridge and surface thermal trough will shift east resulting in slight cooling west of the Cascades. At the same time, we'll be sandwiched in between a weak approaching upper trough from the west and a cut off upper low off the California coast. Mid level moisture will move up from the south ahead of the upper low, providing enough fuel for convective showers in northern California mid to late Tuesday afternoon and evening.

A weather system moving into the Desert Southwest late in the week into the weekend will provide cooler afternoon temperatures and even a slight chance of light precipitation. Water vapor imagery early this morning depicts an eastern Pacific trough with a downstream channel of sub-tropical moisture aloft over northern Sonora and Arizona. This moisture feed has produced widespread upper level clouds, with dry air remaining in the low to mid levels underneath. The previous evening KTWC RAOB depicts a deep mixed layer up past 600mb, an indicator that any features coming off this eastern Pacific trough in its current state will have a difficult time producing precipitation. A series of jet streaks ejecting from the eastern Pacific trough, culminating with the trough crossing the region this weekend, will bring breezy to windy conditions to southeastern Arizona through much of this week.
1211 PM CDT Mon Apr 14 2025 - Cooler and blustery today, with gusts to 40-45 mph possible in stronger showers, mainly in SW MN.
(Rest of Today and Tonight) Upper level ridging will flatten today as an upper trough swings over the Ohio Valley through tonight.
