It’s going to rain/freezing rain/snow today

Ottawa’s currently under a freezing rain warning.  School buses are cancelled, so there’ll be a lot of parents who are either going to be late to work or stuck at home today.

The TAF (terminal area forecast) for CYOW has 13 time periods on it, including the TEMPO and PROB sections, which makes it one of the longest ones I’ve seen:

TAF CYOW 091147Z 091212 07008KT P6SM OVC060

FM0800Z 18008KT P6SM OVC060
FM1000Z 18010KT 3SM -SHRA BR OVC010

One of the rules of thumb I use when scanning TAFs is the longer they are, the less hospitible the weather is.  It doesn’t always work, but for a forecast like this one it does.  At least there’s no SG, PL or GR (to name a few) in it.

I really can’t wait for summer to arrive.
