not much change in the sensible weather over the next couple of
days as upper ridge remains over the area. Slightly better low
level moisture resulted in isolated convection mainly in the
favored terrain areas of southeast OK Friday and similar results
expected both today and Sunday. Progged low level thermal fields
support a degree or so of warming each day. Heat index values
likely to exceed 100 in many spots but should remain below
advisory threshold.

Ridge will be broken down as series of upper systems in main
westerlies move across northern states. First system will push a
frontal boundary into the Central Plains by late Sunday, with some
potential for storms associated with this boundary to approach
northern OK by early Monday. Model data continues to suggest front
will push farther south Tue night into Wed with higher precip
chances arriving at that time. This will also knock temps down to
slightly below normal levels for the last half of next week. More
significant cold front may arrive prior to next weekend.
