I am starting to take a look at the possible weather conditions for memorial day. Basically this pattern means that we will see high pressure develop over Greenland which in turn causes the jet stream to dip over our region.This is not the only factor to look at however. This increases the chances for more unsettled cooler conditions over our area. You have to know how to read and interpret the previous results to derive a pattern that can be used in your “prediction.” The higher the perceived probability, the higher are your chances of winning. By the time we get to Wednesday night the chances at decent rain will increase as waves of low pressure will develop and spread more steady rain into our area especially by Friday. As the low pressure center approaches the moderate risk area, a dryline will come out just ahead of the low pressure system.

If skies are clear with calm winds in this area, we will probably see our first morning with temperatures at or just below freezing – so quite a change on the way. Arizona this morning. The main impact of this fast-hitting weather feature will be some gusty east to southeast winds later this morning. The early WRF-NAM forecast from Atmo this morning, shown below, is for 10-m winds valid at 9:00 am this morning. The long term models are hinting at a trough (area of lower pressure and unsettled cooler conditions shown by blue regions) near the east coast shown below. I do not expect a washout for the early part of the week, just partly to mostly cloudy conditions with showers at times. This is so very true for Majorca Weather, which gets little cold due to mountains that are also part of the island. It appears that Monday night could be quite cold here in the north part of Tucson along the Rillito.

For future reference, those two parameters will show up on all model graphics we analyze here today. There is a moderate risk of severe thunderstorms as outlined by the Storm Prediction Center for the Southern Plains today. They instinctively know when winters will be very long and cold or when a storm is coming up. If this image is taken verbatim we would be fine, but I am concerned that we can see that trough more to the west over our region, especially if the model slows down a storm system entering the west coast. Over the winter, I have been using a very wide variety of indices. The relative humidity in the atmosphere must be at least 30 percent for the negatively charged particles to have sufficient moisture available to produce precipitation producing clouds. However, already at this early time of day, the mid levels of the atmosphere are stocked with over 2000 j/kg of instability, and forecasts are for this to increase past 3000 j/kg. The Mummy (1932) a silent picture with horror icon Boris Karloff in the title role, remains a classic, with unforgettable make-up and atmosphere. Home additionally remains disturbing with health of family and relatives.

3. It helps to improve human activities for the betterment of people e.g A society can develop irrigation scheme when finds show that there is food shortage. Elderly people with poor vision and dementia urgently need to be identified as they are at an increased risk of auto accidents and accident-related injuries to themselves and others. The proximity of the front and dry line to the low pressure system lead me to believe that any storms that form may be influenced by the low pressure system’s wind field, thus possibly enhancing the risk for tornadoes. Determine the contribution of a solar system to satisfy a portion of the load. More importantly, the ECMWF global ensemble system has TWICE the resolution of the American system (18 km grid spacing for ECMWF, 35 km for the US GFS). A low pressure system will be stationed in northern Texas, with an occluded front stretching horizontally from central Oklahoma through the Carolinas. There will be a trough of low pressure in east Asia 6-10 days before Memorial Day weekend.

Before anyone says anything, I firmly stand by statements that I meant when I said that there ought to have been more cold and snow this month- some indices were favorable and it just didn’t happen. I’ve always wanted to see this lake – you’d think, since I grew up in Ohio, I’d have been to Lake Superior by now. Looking at the correlation graphic on the left, we see that there is a positive correlation between MJJ MEI values and DJF 50-millibar geopotential heights. There are reasons for crime, but the best methods for stopping it may not simply be targeting individuals – but may instead come from larger social changes. Because there are so many different time zones in the world, it gets hard to track models- much more if some are made in different continents. More western parts of the Mid-Atlantic should see more precip out of this unsettled weather. Needless to say, that will spark a severe weather event. Looks like what you add it all up some decent rainfall will be experienced by some areas especially over PA from this week’s activity.
