major frost/freeze coming!!!
Comments (12)Forecast by NWS is for this coming morning. I'd better protect my plants when I get home tonight!

EVEN COOLER TEMPERATURES ARE EXPECTED ON WEDNESDAY AS THE COLD LOW PRESSURE SYSTEM CLIPS THE NORTH STATE AND THEN MOVES INTO THE GREAT BASIN. ONLY VERY LIGHT AMOUNTS OF PRECIPITATION ARE EXPECTED WITH THIS DRY SYSTEM WITH MOST SHOWERS OVER THE MOUNTAINS BUT SNOW LEVELS ARE LIKELY TO BE QUITE LOW.

Comments (14)Hey Mike: The forecast on the Weather Channel site was from October when it was believed that an El Nino event would occur. However, it did not. The NWS states that the ocean is in an ENSO neutral condition now which means the water temperature is neither warmer (El Nino) nor colder (La Nina) than average. One forecasting factor that I did not include in the original post is the following statement: "A significant wildcard in the upcoming winter outlook is the uncertainty associated with the phase of the Arctic Oscillation (AO) which the majority of the current literature indicates loses predictability quite rapidly beyond a few weeks." Without getting into a technical description of the AO, if you remember several years ago when we had the freezes here, it was the AO that pulled a significant amount of cold air from Canada into the US due to a change in the location of the Jetstream. Below is a link to a good, relatively non-technical definition and discussion. The broken forecasts of several years ago had significantly understated the impact of the AO on the winter weather. At that time, the AO was "negative" (see graphic below). Anyway, the temperatures and precipitation patterns here in Tucson certainly support the revised NWS forecast. We are between 10-15 degrees above average with very, very little rain. One question to the folks here in Tucson is how much are you watering your trees now? Regards, P. Here is a link that might be useful: Arctic Oscillation...See MoreLatest Arctic Blast Update from Friday Evening
Comments (19)Jay, I don't know what's happening in the rest of Oklahoma, but here at our house, very light rain started falling around 3:45 a.m. when the temperature was 36 degrees. Then, as the temperature fell, the rain transitioned, first and briefly to freezing rain, then to sleet which fell for a while, and then to snow, which has been falling for about an hour-and-a-half. Within the last 5 minutes, the flakes have become huge but also have smaller ice pellets mixed in with them. Our temperatures have been hanging right around and just below freezing all morning. The thermometer on the front porch has dropped from 33 degrees, which is what it was when the snow started falling, to 30 degrees, where it has remained for the last 55 minutes. Tim drove home from work in it this morning, but the temps had stayed higher than initially expected in Dallas, so they were getting rain only and nothing frozen. Of course, the further north he drove the worse the weather became. Overall, our forecast is for slightly colder weather and a little more precip over the next couple of days than initially forecast. However, since the freezing rain was very brief, we don't seem to be in danger of having power outages, which is always my primary concern with weather like this. We are likely to lose internet service at some point. The deer are out there eating the deer corn and the wild birds are eating the seed I put out late yesterday evening. The fact that they came out to eat in the snow tells me they think it will last a while. Generally, they stay under cover and wait for the snow to end and then come to the feeding area to eat. I have coffee in the big thermos bottles and a pot of ham bean soup bubbling away on the stove, so I'm ready to feed the firefighters if we have calls today, except I still need to whip up a couple of batches of corn bread muffins to go with the soup. It is going to be a long, boring stretch of cold days, but it certainly won't be as bad as last year's winter weather that wouldn't end. And, as long as the internet and satellite TV are working, we can at least amuse ourselves with them. The snow is pretty, but after about 3 days without sunshine I start getting cabin fever. We had sunshine in great abundance yesterday, so I shouldn't start feeling sun-deprived for another couple of days. Dawn...See MoreDo Carnations Overwinter in Pacific NW?
Comments (3)They are very closely related and really the only thing that would prevent their overwintering is less than ideal drainage. Dianthus of any kind really prefer fast drainage and often our winter soils just remain too soggy for them to be happy - they are certainly plenty cold hardy. If you are growing them in containers, just make sure you use a good quality, fast draining potting soil (no Miracle Gro!!) and keep the containers out of the worst of the direct weather in winter. And depending on container size, you may want to shift them into the garage during any Arctic blasts that may come our way this winter....See MoreKW PNW Z8
