2:00pm Monday, May 23:
It's been one of the coolest, dampest May's on record here, but the
tables are about to turn on us. After a seasonable start to the week
(today), with a leftover afternoon shower/storm, conditions will
suddenly turn Summer-like with highs near 80 degrees on Tuesday...then
warming into the mid/upper 80s for the second half of the week!
The pesky upper-level low that's plagued us the past few days will
finally exit out to sea tonight, and a jet stream ridge will build
over the East Tuesday through Saturday. A passing warm front may yield
a shower Thursday, otherwise the midweek will be mainly dry. Friday
may then be the warmest day (near 88?), although isolated an isolated
pop-up shower is possible in the afternoon. But again, unlike the
persistently dreary conditions of recent weeks, any shower activity
this week will be short-lived.
The Memorial Day weekend forecast is hard to commit to in a highly
nuanced way as of midday Monday (check back Wednesday, and I'll nail
it down). The reason for the uncertainty is two-fold: 1. a backdoor
cold front may move in from the Northeast late in the weekend--this
would bring a day or two of cooler temps, due to a chilly NE wind off
the Atlantic, 2. a developing low pressure (perhaps a small hybrid
subtropical system) off the southeast US coast may push some rain our way
by Monday...although this is far from a for-sure. If neither of these
concerns come to fruition, then unseasonably warm and mainly dry
conditions will prevail through much of the weekend. Here's hoping!
