Better convection chances will take place tonight with a number of
better factors in place across the region.

We will see more of our typical northwest flow summer time
thunderstorms this evening through early Monday morning. The upper
ridge will continue to buckle with the ridge axis shifting east. A
more pronounced short wave aloft rotating around the upper ridge
will dive down east-southeast tonight promoting increased
overnight convection. Convection was already developing in central
New Mexico this afternoon in response to this short wave.
Clearing low stratus in eastern New Mexico will give way to
healthy surface based instability this afternoon. During the
evening and overnight hours locally, elevated instability will
continue amidst continued moist southeasterly flow. Given a very
unstable atmosphere, storms entering the region from the west will
be capable of becoming severe with large hail and wind the
primary threats.

Monday and Tuesday continue to remain more questionable in terms
of thunderstorm chances. An upper level low in southwestern Canada
will continue to flatten the ridge. We will lose much of our upper
level support with a decrease in jet level winds. After midweek,
we will see mostly zonal flow aloft but rising heights/thickness
values will boost temperatures back above seasonal averages. The
upper low over southwest Canada will move into the Northern Plains
and upper Midwest by late week sending a cold front down close to
the region. However, models have been backing off with this front
for Friday night/Saturday morning.
