Hot Hot! Mother Nature's Giving It All She's Got; But How Long Will It Last? /updated 3/22/2012/

As I continue work in my yard; I see vegetation growing that is clearly weeks ahead of schedule...Magnolia in full bloom (about a month ahead)...numerous flowering bushes 3-4 weeks ahead (next thing you know; the lilacs will start their flower buds...a good 4-5 weeks ahead as they usually bloom late April into early May). This is insane and the unprecedented summer-like heat continues as once again; temperatures are broaching the 80 degree mark easily today (3/22/2012). All trees, deciduous and fruit, are rapidly budding and growing out now! For more on the unprecedented warm to hot March pattern including agricultural interests; see here for further details.

While it's beautiful summer-like weather now; (unfortunately I have to admit, I cranked on the air-conditioning for a short while yesterday and any money saved on heating bills this past winter will fly out the window with air conditioning) it could prove devastating for garden and agricultural interests were there to be a hard freeze and frost. I'm sorry to say; a frost or freeze is highly likely yet along with even the risk of snow. We still have 3 to 4 weeks we have to squeak through before the risk begins to drop off; precipitately.

Our first real cool-down to watch is expected late in the weekend into early next week! Our latest models (3/22/2012) are disagreeing on the extent of the cool down but this one will definitely have to be watched!  A large polar high pressure system will stick its beak down into the Great Lakes and points east early next week and bring quite a change from the summer-like weather we've recently felt! How far south the colder air is able to infiltrate the area remains to be seen; so stay tuned.

(previous blog from 3/20/2012)
A record, summer-like upper level ridge of high pressure continues to dominate the eastern half of the nation. This is bringing unprecedented warmth to the much of the eastern half of the nation; including the Great Lakes and Southeast Lower Michigan. I first blogged about this system last week on the 12th and the mammoth ridge has indeed come to fruition per numerous model projections.

Since last week; these are the records that have been established.
