Welcome to 'June-uary'?

Welcome to 'June-uary'?
SEATTLE -- The lore of the great chill of spring 2008 is about to write another chapter.

Another weather system is dropping down from Alaska today, bringing not only another round of chilly rain to the lowlands, but snow to the Cascades -- even down to Snoqualmie Pass level!

Snow levels will drop to 4,000 feet early Monday evening, then to 2,500-3,000 midnight, affecting all mountain passes overnight.

A Heavy Snow Warning is in effect from 6 p.m. Monday through 8 a.m. Tuesday for the North and Central Cascades. As much as 10-12" of snow will fall by Tuesday morning -- especially over the Northern Cascades.

The fact that it is June means road temperature are warm enough that actual accumulations on the roadways are expected to be limited, but the snow itself can make for poor driving conditions with low visibility. And add in the fact that you're probably not really used to driving in snow in June.

Those hiking and camping in the high back country and wilderness areas will face winter-storm like conditions and should prepare accordingly.

Similar conditions are expected in the Olympic Mountains as well, with as much as 4-9" of new snow as low as 3,500 feet. Again, hikers and campers should prepare for winter conditions.

In the lowlands, high temperatures today are only expected to reach the mid 50s with gusty south winds to 35 mph Monday afternoon -- perhaps 40 mph gusts along the coast and in the North Interior.

So far this month, Seattle's average high temperature is 57.2 degrees -- this is a full 5 degrees below the record coldest average for June and over 12 degrees below the normal average high, although it's highly unlikely we'll stay this cool the entire month. So far, we've only had one day this month be over 60 degrees.

Some other records: This is the coldest first 8 days of June in Seattle history. Also, Seattle has never gone the first 12 days of June under 65. That record is in jeopardy, but will be close.

In the meantime, get those Valentine's Day dinner reservations in now...
