...no thunderstorm areas forecast...
...summary...
thunderstorm and severe potential are low tuesday.
...synopsis...
broad troughing over the eastern us is forecast to weaken and shift
into the atlantic tuesday ahead of a deepening pacific trough
approaching the west coast early wednesday. persistent ridging over
the southwest will favor strong but largely zonal mid-level flow
over much of the central conus.
a dry and cool airmass is expected with surface high pressure over
the southwest and southeastern us the primary feature. as a result,
large-scale subsidence and continued dry offshore flow will suppress
buoyancy and thunderstorm development over much of the country. the
only exception to this may be near the or/northern ca coasts into
early wednesday morning. here, cool mid-level temperatures and
onshore flow could support a sporadic thunderstorm in the early
morning hours ahead of a strong cold front expected to move onshore
wednesday.
