We finally got some much needed rainfall across portions of the area. \u00a0It wasn&#8217;t a lot of rainfall, but at this point, we&#8217;ll take it. \u00a0The past several weeks have been warm and dry. \u00a0Recently, the humidity has increased and even more like summer. \u00a0Looks like that will end on Tuesday as a cold front moves through the region during the evening. \u00a0We may even get some severe weather, which I&#8217;ll discuss below.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">One item I wanted to address here is about our Spring season. \u00a0The last several weeks have been very dry. \u00a0Given the dry conditions, fire weather hazard has increased, so, keep an eye on NWS outlooks. \u00a0The bulk of all the active weather has been over the Central US from Texas north to northern Plains. \u00a0The Jet Stream has been consistently been bring several troughs into the Central US with strong weather systems. \u00a0The persistent pattern, which has kept us dry has brought plenty of severe thunderstorms with strong tornadoes, damaging winds, large hail and heavy rainfall. \u00a0Record breaking rainfall that has led to serious flooding over Texas continues. \u00a0This time last year, that wasn&#8217;t the case for the folks out there. \u00a0Amazing how the weather pattern can vary each year. \u00a0<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">One final note, the current ENSO phase is a weak El Nino, but will get stronger as we get into the summer. \u00a0What this may mean is that our summer could be cooler, but what about precipitation and the hurricane season. Well, typically, the Southern US gets hammered with a lot of precipitation and for the hurricane season, below average activity. \u00a0So, for folks that live along the coast, that is great news, but remember it only takes on major hurricane to hit the US, so you have to always be ready for such a landfall. \u00a0We&#8217;ll definitely have to see how this El Nino plays out the next several months.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">Okay, thats it for some thoughts and now check out my updated outlook below for the next 2 weeks. \u00a0<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><br \/>\nOne final note, for folks that really get into tracking weather, I&#8217;ve now uploaded the model ensemble images. \u00a0You&#8217;ll be able to check that for each forecast period in the Technical Weather. \u00a0<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">\u00a0<\/span><\/p>\n<p><strong><span style=\"font-size: 12pt;\">For official outlooks, please check\u00a0out the following links<\/span><\/strong><br \/>\n<span style=\"font-size: 12pt;\">&#8211;

Checking with the Weather Prediction Center (WPC) precipitation outlook, shows totals about 0.50 inches. \u00a0But given how humid things are, heavy rainfall of an inch can easily occur with any thunderstorm. \u00a0The other threat is severe weather possible on Tuesday evening. \u00a0The best instability appears more to the Northeastern US. \u00a0Confidence on this event is medium for it
