Winds will become southerly by tomorrow morning and moisture will begin streaming in, but no incoming systems to monitor attm. Cooper LONG TERM...Saturday Night Through Wednesday Not many changes to the long term portion of the forecast this afternoon. Above normal temperatures will be in place for the first few days of the forecast with H500 ridging in place south of the area and surface high pressure to the southeast. Even as H500 shortwaves traverse the country from west to east in the zonal flow, little interaction will be noted locally thanks the ridging to the south. Even as a front moves into the state, rain chances will largely be confined to northern portions of the forecast area. By mid to late week, it appears mid-level ridging will build again over the western US while troughing will dominate over the east. Temperatures will begin to reflect this change, with below normal readings expected across the area. 67 && .LZK Watches/Warnings/Advisories...NONE. && Aviation...57
