"Sunday night through Tuesday, southwest
flow aloft will usher warmer temperatures into the region along with
moisture and increasing rain chances. Not much has changed with the messaging. Due to expected sub-freezing pavement temperatures and the potential for a wintry mix starting Monday morning, there remains the potential for some freezing rain and
icing conditions. This will be better refined in later forecasts as we get closer to the time and may require the issuance of a weather headline.
Tuesday night through Friday, the forecast blend has predominantly rain chances, which are more focused on our SE half of the
CWA. Temperatures will be in the 33 to 40 range for highs each day, with some areas remaining above freezing overnight as well. A good deal of
snowpack compression and melting will be seen along with the rain. While antecedent unfrozen ground under the
snowpack may absorb the rain and snowmelt, some rises on streams, creeks, and tributary rivers are eventually expected along with
ponding of water in poor drainage areas. With the
rainfall, structures with snow- covered flat roofs will
likely see added stress with the increased weight from the
rainfall being absorbed into the snow on the roof. Some weaker structures may see their roofs collapse in. There are still some uncertainties with this systems including
moisture, timing and track of each system. Stay tuned."
