Area Forecast Discussion
National Weather Service Tulsa OK
223 AM CDT Sun Apr 23 2023

...New SHORT TERM, LONG TERM...

.SHORT TERM...
(Today and Tonight)
Issued at 222 AM CDT Sun Apr 23 2023

The main item of interest will be frost/freeze potential this
morning and again tonight with this unseasonably cool airmass in
place.

Clearing skies across the north has already allowed temps to drop
off into the mid 30s near the KS border, so a frost and possibly a
freeze at the typical cooler valley spots is most likely there. Some
lingering light rain is forecast down near the Red River this
morning, ending by midday. Cloud cover will clear from north to
south as the day wears on, so most of us see some sun today,
unlike yesterday. This will yield warmer high temps for most.

A surface ridge will be overhead tonight with mostly clear skies.
It is these situations where the blended guidance (NBM) tends to
be too warm. For the forecast lows tonight, a blend of the colder
NBM 25th %ile and CONSMOS, which typically handle radiational
cooling better, is preferred and will be used. As such, another
frost advisory was posted and it's not out of the question that
the colder valley sites, such as KFYV and KBVO, dip down to
freezing.

.LONG TERM...
(Monday through Saturday)
Issued at 222 AM CDT Sun Apr 23 2023

In what has been a dry April so far (aren't April showers supposed
to bring May flowers?), we're finally going to see some widespread
rain this upcoming week, without the penalty of higher impact
severe weather which is what we come to expect from the April 20s
around here.

Rain and storm chances ramp up Monday night into Tuesday in a
warm/moist advection regime north of a warm front over TX and in
advance of an approaching shortwave trough from the W/NW. After a
relative lull in the action Tuesday night, we should see another
round of showers and storms Wednesday and Wednesday with the upper
system, tapering off Thursday. After all is said and done,
widespread 1 to 2 inch rains are expected across the forecast
area, which will be welcome for most. The warm sector is expected
to stay south of the Red River thru the event, suggesting that
severe potential will be pretty low, quite unusual for this time
of year. The ongoing stretch of cooler than average temps will be
the rule for this entire upcoming week.

The upper pattern amplifies toward the end of the week, as a
strong upper system dives south out of Canada down thru the
central CONUS. This will drive another front south thru the region
Friday into Saturday, bringing another chance for rain and a few
storms. Thus, expect cooler than average temps once again for next
weekend.
