chance of scattered showers throughout our forecast area. The upper
level trough driving the surface front will move over our region
later in the day Saturday into Sunday. As the upper level trough
shifts further eastward, a strong surface high pressure system will
build into the region from the upper midwest and the great lakes
region on Sunday. Temperatures looks to rise into the upper 60s to
low 70s on Saturday along with some light winds.

Sunday through early next week, a strong high pressure system will
remain over the region. Skies are expected to remain mostly clear
with temperatures starting below average for the end of april in the
low to mid 60s and slowly rising into the 70s by Tuesday. Average
temperatures for the beginning of may are normally in the low 70s
which means that temperatures will likely reach average range or
higher for this time of the year next week. Winds look to remain
light and skies mostly clear through the long term.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
