The totals were last updated at 3:30pm local time, and haven't been updated since, so maybe this is the last update we'll get today. Looks like it will be at least Monday before a final number comes in, as the reports say they will be counting the question (provisional) ballots on Saturday. Current totals:

Begich   125019

Stevens 125016

Update from the Alaska Board of Elections:

Nate Silver reports:

Prior to today, Stevens' lead over Begich had been 3,257 votes, with the state of Alaska having reported that about 90,000 votes remained to be counted. Although some of those votes will be thrown out (such as duplicate votes when the voter both sent in an absentee ballot and came to the polling place), there are still plenty of votes remaining to be counted, and Begich is making up ground at a sufficient pace that he appears more likely than not to surpass Stevens.

A significant number of additional votes will be counted before close of business today, although approximately 8 of Alaska's 40 house districts won't finalize their counting process until Friday at the earliest. The areas that will report late consist mostly of rural, Begich-friendly districts (contrary to our earlier reporting, Begich performed quite well in rural Alaska; his weaknesses were in the Anchorage Suburbs and the Mat-Su Valley).
