Frost Advisory for tonight..

Env. Can. Advisory:

2:01 PM EDT Friday 22 May 2015
Frost Advisory in effect for:
  • Ottawa North - Kanata - OrlĂ©ans
  • Ottawa South - Richmond - Metcalfe
Frost may destroy fruit crops, vegetables, and other plants.

Wide spread frost is expected. Under clear skies and calm winds, ground temperatures overnight and early Saturday morning are expected to be at or a few degrees below freezing. The exception is for areas very close to the Great Lakes where temperatures will remain a couple of degrees above freezing.
Take preventative measures to protect frost-sensitive plants and trees.

Weather Advisories for Frost are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.

Texas drought

Extreme drought erased in Texas as rainfall reaches many time normal.

A look ahead

Remaining mild and spring like for the next week or so.  Monday/Tuesday look to be quite wet.  Later next week will have a cooling trend with below normal temps likely.. But not snow.  I think there no more snow this spring...unlike the US front range.  Ouch. (map courtesy of Weather Bell)

Quick post again...

Am I getting out of Dodge just in time?
Maybe.  Total snow over the next 10 days about a foot, according to the ECMWF.

A quick look ahead.

Snow tonight, 2-4cms looking like.
Warmup to rain on Thursday.
Back and forth pattern for the next while but generally cooler than normal.
HOWEVER, it is looking like mid-April for the flip to real spring.

Looking forward...

The next couple days will see us get the coldest air on the planet, relative to normals. It will be about 11 degrees C below normal but will moderate as the week progresses.
Thursday will see a small system coming that will be milder than today, giving more precip of the liquid kind than frozen.   Likely another cold shot next weekend.
Longer term, unfortunately the mean temperatures will continue to be colder than normal, likely until at least mid April, interspersed by warm day teases.
The next two weeks according to GFS Ensembles, maps courtesy of WeatherBell.

Week 1

Week 2

Looking forward...

It's been a nice couple of days and the snow is melting fast.  Yet as I have been twittering (ahem @YFNWG_Ott), winter isn't done.   A cold front is coming through this evening dropping temperature more than 15 degrees from current temperature.   There will be merging of a clipper and a storm coming from the south on Saturday (see pic from A/W)  This will give us 5+ cms of snow Saturday into Sunday.   The GFS and Euro are more enthusiastic about the snow than the Canadian.

Beyond that, after a day or so of mild temps early next week, there will be a period of below normal temps with the obligatory chances for snow.  There is indication on the ensemble models that this will generally be the case into April.

Quick post from TKD

Waiting for the boys at TKD,  admiring the full moon on a crisp evening.  

After the cold in the next couple of days, we will get a few cms of snow on Saturday and a flurry or two on Sunday.  Tuesday through Thursday will be mild, slightly above normal.

Again, I've joined the twitter-sphere @YFNWG_Ott mainly to provide more up to date weather information and news.  And whatever else catches my fancy.   The blog will remain for longer posts.
