.PREV DISCUSSION... /issued 301 AM CDT Fri Apr 27 2018/

DISCUSSION...
Warm weather will continue into the weekend with the relatively
dry airmass and light winds. The center of the airmass will pass
over Oklahoma today and winds will stay rather light from the
south into Saturday. Changes start Sunday with the development of
a lee surface trough and northward movement of lower level
moisture across western Texas. A long wave trough will be
positioned over the western U.S. by then and remain there through
the middle of the next week. By early Monday, surface moisture
will have increased greatly over much of Oklahoma. This will be in
place for the first and weaker wave later Monday that will move
from northern NM into KS and bring a slim chance for thunderstorms
to western OK. By Tuesday southwest flow increases substantially
and the dryline is forecast to advance into the western half of
Oklahoma. On Wednesday, with the upper low still over the
southwestern U.S. another impulse will help mix the front at least
into western OK by afternoon. Both Tuesday and Wednesday are
potential severe weather days. By Thursday, the upper trough
exits and a front moves southward decreasing rain chances and
bringing modestly drier air.
