the stage will be getting set for an active weather day friday as
strong impulses approach an environment that will be becoming
increasing more unstable with modest deep-layer shear. in
addition to the instability, precipitable water values will be
topping out between 1.25 to 1.50 inches. a narrow atmospheric
river will translate over the area friday afternoon, adding to
the potential for locally heavy rainfall in addition to the
damaging wind threat.
the potential for heavy rain will continue early next week as
a strong impulse reaches the area. wpc indicated rainfall amounts
around 1.00 inch across the entire forecast area monday into
monday night. these rainfall amounts will add to the potential
for renewed river flooding. at the present time, 6 of the area
rivers were in "action" stage and 3 of the area rivers were in
"flood" stage.

vfr conditions and southerly winds around 10 knots anticipated
pre-frontal into tonight. a convective outflow does attempt to
survive into northern in after daybreak tomorrow morning with a
non-zero chance for a few lingering showers. better chances for
scattered showers and storms will come in the afternoon if
enough heating is achieved along a cold front. restrictions into
ifr-mvfr will be possible during this time.
