several fronts this week will bring wind shifts and chances for
rain, but the warm airmasses will stay in Oklahoma until Thursday.
The first front tomorrow will bring gusty northwest winds and
increased fire danger to western Oklahoma. Relative humidity may
just lower to 20 percent, so a Fire Weather Watch is effective
there tomorrow afternoon. This front is expected to stall tomorrow
night near or south of the Red River. This will be the weather
maker Monday and Tuesday. On Monday weak northwest flow aloft is
expected to impinge on weak southerly winds at the surface for
modest vertical shear. Thunderstorms are possible along and north
of the front in southeast Oklahoma later Monday. A better chance
for thunderstorms comes Tuesday when slightly stronger middle-level
flow is across the area and the front has moved north into more of
Oklahoma. Southern and central Oklahoma have the best chance for
rain. The next front comes Thursday followed by a second, stronger
one Friday. The one on Friday finally brings cooler, more
seasonable weather. A chance for thunderstorms will come with this
front especially in south central and southeast Oklahoma. Middle-
level flow and vertical shear is stronger this day which may lead
to stronger thunderstorms.
