...Potential for Significant Rainfall This Week...

The first round of rain arrives today followed by another rain
system Wednesday into Thursday. Plenty of deep layer moisture
will be available to both of these storm systems, increasing the
potential for significant rainfall amounts. For the first system,
confidence is currently highest in rainfall amounts of 1 to 1.5
inches occurring across the area, with locally higher amounts
around any thunderstorms that may develop this afternoon. For the
mid to late week system, heavy rainfall is possible area wide
depending on the track of the low pressure area. Confidence is
increasing in regards to the track and timing of the second
system, and current indicators suggest much of the area could see
another 1 to 2 inches of additional rainfall. Given the saturated
ground and ongoing minor river flooding from the March 30th event,
these 2 heavy rain events will likely lead to areal flooding and
renewed sharp river rises.
