onset of this precipitation until around 20Z based on trends in
the latest models. Will include slight mention of thunder with
strong shear, forecast LIs -1 to -2 and SPC indicating a general
thunder outlook although lapse rates are weak. Precipitation
amounts that occur with this system should be very light, mainly
a tenth of an inch or less in most areas.
