PHILADELPHIA (CBS) — Conditions will be generally nice to start the week, albeit a bit cool as you step out the door on Monday morning. Highs will warm into the mid-60s, under mostly sunny skies with a westerly breeze.

* There will also be an enhanced risk of fire spread late this morning and into this afternoon, due to low relative humidity levels and breezy conditions. *

Monday night will feature some clouds, and a passing shower is possible as a small and week disturbance passes through. These will move out during the overnight period, and with diminishing winds towards daybreak, frost advisories have already been issued for areas to our north. We expect to see a few more as we progress towards Tuesday morning.

Tuesday the sunshine returns, mixed in with a few clouds and temperatures will inch towards the 70 degree mark a few more degrees. By Wednesday we expect to reach it, with continued mostly sunny skies as high pressure remains in control.

Thursday we will be tracking some showers associated with a warm front off to the west. As that front moves north of us, southerly winds will usher in some of the mildest air of the year, and we are likely to reach 80 degrees at some point on Friday. The weekend looks a little unsettled as of right now, but temperatures remain mild.

This Day in Weather History:
Cinco de Mayo celebrates Mexico’s independence. Of course Mexico is known for its often sizzling climate, and ironically there have been some notable warm weather events in the U.S. on the 5th of May.

• In 1930, an exceptional heat wave began in the mid-Atlantic, marked most notably by when the temperature at College Park, VA, soared from 43 degrees to 93 degrees that day.

• In 1987, unseasonably hot weather prevailed in the western U.S. A dozen cities in California reported record high temperatures for the date. Afternoon highs of 93 degrees at San Francisco, 98 degrees at San Jose, 100 degrees at Sacramento, and 101 degrees at Redding, were the warmest of record for so early in the season.
