DAYS 1-5 (MAY 7-11)
Not making any significant forecast changes on this update. Quick warm day today but clouds move in and eventually a shower and potential thunderstorm threat as a cold front approaches, then passes through the region tonight. This sets up another nice but cooler day tomorrow. Broad low pressure approaches Thursday, which starts dry and ends wet, and makes Friday another wet day, but it is gone by the start of the weekend when another area of cool high pressure will move in.

DAYS 6-10 (MAY 12-16)
High pressure brings fair weather May 12. Low pressure brings rain May 13. High pressure brings fair weather May 14. A system passing to the north sends clouds and a rain shower threat into the region May 15 into May 16 before clearing.
DAYS 11-15 (MAY 17-21)
The forecast remains low confidence, but one change I am starting to see is that low pressure may evolve away from the region and high pressure closer to this area bringing a greater chance of prolonged fair weather. Still have to figure this out.
