How can I find historical Alaskan weather?

Here in Juneau, we're constantly talking about the weather, even though it's pretty consistent, especially this summer (read: so.much.rain). But what if you want to know what the weather was in the past?

We recently had a question like this from a patron looking for the weather on the day he was born. He asked that we send him the weather section from the newspaper in the town where he lived. That was a great idea. It worked especially well because there was a big storm on his birthday so there was a full article on the weather. We have one of the most complete Alaska newspaper microfilm collections in the world and our microfilm scanners make it easy to scan an article and send it by email.
Weater Report - 24 hours ending at 3 pm today: Wednesday, September 13th, Maximum 52, Minimum 44. Cloudy - Rain. Precipitation - .63.

You can also find historical weather information from the National Weather Service, although the amount of information may differ depending on the local forecast office. Let's say I wanted to know what the weather was like in Nome fifty years ago. When I looked up Nome, it said that the local forecast office is in Fairbanks, with a link on the right side. Then I went to Climate and Past Weather.

From the Climate and Past Weather page, you can find a tab called NOWData, which stands for NOAA Online Weather Data.

In NOWData, you can select the location and information type. Several of the options will give you historical weather data in various formats, so it's up to you which product type you select. I chose the Daily Almanac for September 13, 1967, which shows the high, low, and average temperature, precipitation, snowfall, and snow depth. It also provides the record highs and lows for the observation period, which goes back to the 1890s for many Alaskan locations.
