KEY MESSAGES

Updated at 729 AM EDT Thu Apr 9 2026

- No rain is expected through Monday with low RH's for at least the next couple of days.

DISCUSSION

Issued at 143 AM EDT Thu Apr 9 2026

Currently, fairly weak flow is in place aloft with a shortwave and upper jet well to our north. High pressure is centered off the New England coast. Dry weather will persist with height rises leading to a continuation of the warming trend. Very low RH's can be expected again, likely dropping well into the 20s or possibly teens. Luckily, 850mb flow is 5 kts or less with a weak MSLP gradient. By Friday, a trough/closed low will move onshore from the Pacific with some expansion of ridging from the southwest. This will lead to a continuation in warming with highs approaching 80 degrees. High pressure will recede some but keep dry conditions in place. Similarly low RH values are expected, but low-level flow and the MSLP gradient remain weak.

By Saturday, troughing to the west will approach the Rockies with more significant expansion of ridging from the southwest. Another surface high will progress to our north, leading to dry northerly flow. The height rises will further expand the warming trend. Sunday to Monday, western troughing will move through the Rockies with high pressure shifting further to the east. With 500mb heights reaching summer normals of 5,840m, temperatures will rise well into the 80s area-wide. The stronger MSLP gradient and southerly flow will lead to increasing winds, combined with low RH values. Rain chances do not return until potentially later in the week, but recent trends have trended downward in recent days. This will further exacerbate the drought with Knoxville and Chattanooga now at their lowest year- to-date rainfall (Jan 1st - Apr 9th) since 2007.

AVIATION

(12Z TAFS) Issued at 729 AM EDT Thu Apr 9 2026
