New AVIATION

SHORT TERM
(Today through Friday)
Issued at 315 AM CDT THU APR 25 2024

A cold front, oriented east to west and bisecting the area in half, is slowly pushing southward this morning. Dewpoints south of the boundary are in the mid to upper 50s, with localized patchy fog now developing. North of the front/I-20, dewpoints have fallen into the 40s. The front will continue slowly pushing southward today before lifting back northward this afternoon, in response to a shortwave within northwesterly flow. It is possible a few showers or storms could develop near the front as it lifts northward. Low moisture, weak wind fields, and limited forcing will keep coverage low and any storms limited in strength. Highs this afternoon will be in the mid 70s to lower 80s.

Upper level ridging builds into the area tonight and Friday. The frontal boundary will pivot and become oriented north to south across the northeast, and reinforced by a weak wedge across north Georgia. Continued weak impulses rotating around the ridge will provide lift along the surface boundary for isolated shower and storm coverage overnight and early Friday morning across the northeast. Increasing heights will limit convection Friday afternoon, with highs in the 80s areawide.

LONG TERM
(Friday night through next Wednesday)
Issued at 315 AM CDT THU APR 25 2024

Two significant shortwave ejections will occur across the Plains and Midwest over the course of the Friday night through Sunday period. Meanwhile a ridge will remain in place over the Southeast CONUS through most of Monday. Eventually the second trough in the Plains should progress eastward on Monday afternoon and Tuesday with increasing rain chances mainly north of I-59. Models continue to indicate a cold front that weakens on approach, and the southern portions of our area may remain dry through Wednesday.

A weak front, currently oriented east to west across the area, will slowly drift south and back north today. Winds will remain variable at less than 6kts. A few showers or storms are possible this afternoon as the front lifts northward, but chances at any terminal are too low to include at this time.
