Highs are expected to top at least 70 degrees through Saturday, a good 5-10 degrees warmer than normal, but are no longer expected to threaten any records.

Tuesday and Wednesday could be the warmest, with highs reaching the upper 70s or perhaps 80 degrees. Wednesday could come closest to setting a record for October warmth -- the mark for Oct. 24 is 82 degrees, set in 2001.

While warm air from the south pushes up to heat the eastern third of the country, a high pressure system to our southeast is keeping skies mostly sunny and clear.

Thursday, the warm spell could cool slightly, to around 70 degrees through Saturday. But if it warms signficantly more than that, it could threaten a mark of 77 degrees last reached in 1931.

With lows in the 50s, records for highest minimum temperatures are safe, with marks in the 60s. But lows are still well above normal for this time of year; the lower 40s are more typical for late October.
