An upper trough east of the forecast area is diving south and this has resulted in increasing winds east of the Cascades and the mid slopes and ridges along and west of the Cascades. The thermal trough will be situated along the south Oregon coast, resulting in gusty east to northeast breezes near and at the ridges along the coastal mountains in southwest Oregon. We can expect gusty afternoon and early evening breezes east of the Cascades and the higher terrain west of the Cascades. However, winds are not expected to be as strong as upper ridging builds in and winds aloft become weaker.
/EC/ Today and Tonight: Continued dry and warmer through the period. Early morning satellite imagery/RAP analysis showed a mid level ridge just west of our CWA that is progged to strengthen and shift east over our CWA. This ridging surface and aloft combined with the gusty southerly wind should help temperatures top out warmer than normal and in the 80s. This will help temperatures bottom out warmer than normal as well and from the upper 50s east to the mid 60s west. /22/ Friday through Next Thursday The period will begin with a upper-level ridging across the southeastern states.
340 PM EDT Thu Apr 17 2025 High pressure will move offshore by Friday, leading to a significant warming trend for the weekend. Quiet and seasonable tonight as high pressure to our north progresses eastward. Offshore high pressure keeps lighter SSW flow around, while ridging aloft builds and warms up the airmass in place.
There are only so many ways we can say, again, how beautiful of a day it is across the Florida Keys! High pressure is the dominating feature, and this allows for unremarkable weather conditions to prevail. 74", and most of that moisture is confined to the lower levels. The low level RH was calculated to be 54%, which sounds dry at first, but we compare it to the mid level RH at 9% and we can conclude that there is some low level moisture advection occurring. From synopsis, high pressure building over the Appalachian mountains will define conditions over the Florida Keys for the upcoming weekend.
Low RH is expected again with values in the low to mid 20s expected area-wide. Discussion: Ridging begins to build across the Ohio and Tennessee valleys today, starting what will be a significant warm up as we head into the weekend.
- Active pattern will continue cooler temperatures and chances for precipitation through the forecast period. Current Water Vapor and upper air models show upper low/trough over the central Rockies this afternoon, with southwest flow aloft the FA, and upper ridge over the Great Lakes region. Surface charts depict low pressure over eastern SD. Upper level trough moves over the Rockies and into the plains rest of today into Friday. Deterministic models have come more in line with ensembles on remaining QPF through Friday afternoon, with the higher amounts of 0. 5" over southern part of our northeast WY counties into southwestern SD, as well as the higher elevation Black Hills with upslope enhancement.
An upper-level ridge, currently stretched across the northwestern Gulf, will build into the southeast US through the period. At the surface, high pressure anchored over the western Atlantic will help to provide a persistent onshore flow to the local area. Subsidence from the deep-layer ridging in place will keep rain out of the forecast through Friday night. Lows tonight will range from the low to mid 50s inland to the upper 50s to low 60s closer to the coast.
112 PM EDT Thu Apr 17 2025 A warm front will lift north across the Ohio Valley later today and tonight, leading to a chance for a few light rain showers. It will also usher in a warmer airmass with warm and breezy conditions expected on Friday.
Dry and warmer than normal weather conditions through the rest of the work week across north and central Georgia as a strong mid- level ridge gradually builds over the Southeast US. Temperatures today will climb into the low 70s across far northern GA and upper 70s to low 80s across the rest of central GA. Friday's highs will jump quite a bit from today, reaching the low 80s across far northern areas, with mid to upper 80s elsewhere.
The initial edge of the cold front continues to push southward across central WY this morning, with precipitation beginning to fill in across the north. As the north sfc winds increase later this morning, overrunning precip will begin to build across central Wyoming, and with temperatures steady in the low to mid 30s, precip will be nearly all snow through the day.
Snow accumulations on the order of 1 to 3 inches are possible in the Pine Ridge area.
624 PM CDT Thu Apr 17 2025 - A cold front will bring scattered thunderstorms to central Illinois Friday evening. It's not until the arrival of a cold front Friday evening that guidance begins to erode the cap.

921 PM EDT Thu Apr 17 2025 The forecast is in good shape this evening with quiet weather underneath a building mid/upper level ridge. As the ridge builds over the region, high clouds across NE TN and SW VA will be pushed northeast, and most of tonight and tomorrow will have clear skies. High clouds increase late weekend ahead of a low pressure system.
625 PM CDT Thu Apr 17 2025 An upper-level ridge, currently stretched across the northwestern Gulf, will build into the southeast US through the period. At the surface, high pressure anchored over the western Atlantic will help to provide a persistent onshore flow to the local area. Subsidence from the deep-layer ridging in place will keep rain out of the forecast through Friday night. Lows tonight will range from the low to mid 50s inland to the upper 50s to low 60s closer to the coast.
Lows in the lower to mid 50s expected inland areas tonight, but upper 50s to around 60 closer to the coast due to light onshore flow. This will result in a continuation of clear skies and warmer temperatures than yesterday. Look for afternoon highs in the lower to mid 80s with lows tonight in the 50s.
844 PM EDT Thu Apr 17 2025 High pressure will slowly push off of the Mid Atlantic Coast tonight into Friday.

808 PM EDT Thu Apr 17 2025 High pressure will move offshore by Friday, leading to a significant warming trend for the weekend. Quiet and seasonable tonight as high pressure to our north progresses eastward. Offshore high pressure keeps lighter SSW flow around, while ridging aloft builds and warms up the airmass in place.
From synopsis, high pressure will continue to transverse the region, leading to easterly breezes freshening over the next few days.
The highest snow totals will occur in favored upslope areas of central Wyoming.
600 PM CDT Thu Apr 17 2025 (This evening through Friday Night) Upper-level ridging in place across the region today will begin to shift eastward overnight while an upper-level trough continues to dig through the Intermountain West into the Four Corners region. By this evening, this trough will help to induce lee cyclogenesis east of the Rockies with a cold front slowly edging southward into the Central and Southern Plains. This enhanced southerly flow regime will continue through Friday and Friday night as the cold front advances farther SE into the Ozarks and eventually toward the Middle Red River Valley of North TX and Southern OK by the end of the short-term period. The threat of more showers and thunderstorms will expand slightly farther SE on Friday night as the cold front edges closer but remains just to our NW.
723 PM EDT Thu Apr 17 2025 Dry high pressure lingers over the area through the weekend with temperatures steadily warming each day.
952 PM EDT Thu Apr 17 2025 Dry high pressure lingers over the area through the weekend with temperatures steadily warming each day.
The large amplitude trough is currently stretched generally across western WY this morning, and continues to slowly shift southward across the Rockies. As the trough shifts southward today, the winds sfc and aloft will align better, decreasing the overall lift near the sfc, bringing most precip to an end through the afternoon. With the clear skies and cold pool still in place behind the front, temps tonight will drop considerably, with most areas falling into the lower teens and upper single digits.
1241 AM CDT Fri Apr 18 2025 (Rest of tonight and Friday) Evening analysis indicates the presence of a broad sub-tropical ridge off the SE Coast, extending SWWRD across the FL peninsula and into the eastern/northern Gulf.
