<span style='color:red'><span style='font-size:13pt;line-height:100%'>Folks I have added something new to the forecast so please read the whole forecast. The new additions are at the bottom.
Folks after a somewhat so so weekend Troop wise along US. East Coast. It looks like at this point in time that, Monday through Friday, the week will start out Poorly for those of us along the North East U. S. East Coast and Also for those of us along the South East Va Coast and North East NC as well. However When Tues and Wed come rolling in thing will pick up some what along the East Coast with Wed looking to be the best so far. And it looks like the week will end (Friday) as it started, Poorly. #So, don't abandon ship just yet. I suggest you try to make the best of it and Look at the hourly weather forecasts on the Weather Channel Web Site (weather.com) and see when a temp inversion is most likely to take place, Also, if FOG #sets in this could be a temp inversion happening in your area. As the warmer air is overlaying the colder grounder air, so, give it a shot and through out a CQ. Also, #listen for beacons to the North and South. Beacons are usually low power and if you can hear them the there's a good possibility that Troop is about. These are just a few things that you can do help make VHF / UHF SSB Contacts even when the Tropo is not at it's best or is at it's best. Another words give it that old college try.
Troop is currently showing for Monday from Prince Edward Island South to Long Island NY expect Poor Tropo Conditions along the coast. From The Southern part of Long Island South along the coast to the Northern part of the Delmarva conditions will be Poor to Moderate. Looking from the Southern Delmarva along the coast to the NC State Line Tropo Conditions will be Poor. From the Outer Banks South along the coast to the FL Keys conditions will range from Fair to Moderate along the Southern NC Coast to Good along the SC and GA Coasts. And from Jacksonville Fl coast to the Keys expect Moderate to Marginal Conditions. Looking inland North and North West from Long Island NY to Prince Edward Island , Expect Poor conditions to the West and North West. From the Northern Delmarva to Long Island expect Inland conditions to be in the Marginal range to the West and the Poor Range to the North and North West. From the Southern Delmarva to the NC State Line expect Inland conditions towards the West to the Poor with Poor to Marginal conditions to the North and North west. However looking Inland to the South and South West expect conditions to range from Poor to Good the farther South or South West you go. #Looking Inland from the Outerbanks to the FL Keys expect Poor to Good conditions to the South and South West.
For Tuesday from Prince Edward Island South to Cape Cod expect Poor Tropo Conditions along the coast. #From Cap Cod South to Long Island expect Fair conditions along the coast. From Long Island South to the Delmarva expect Poor conditions along the coast. From the Delmarva South along the coast to the FL Keys, expect Fair to Strong Conditions. With the best conditions off the FL coast around COCO Beach FL. #Looking inland North and North West from Long Island NY to Prince Edward Island , Expect Poor conditions to the West and North West. From Long Island South to the Delmarva expect Inland conditions to be Poor to the West, North and North West. Looking Inland to the South and South West from the Delmarva to the FL Keys expect a wide range of conditions from Fair in the Delmarva to Strong in Central Fl and looking to the South West from the Delmarva from Fair to Good.
So, if you are in the State of Virginia you may want to point your beam to the South or South West and through out a CQ. Likewise if you are in the South or South West point your Beam to the North or North East and Through out a CQ.
For Wed from Prince Edward Island South to Cape Cod expect Poor Tropo Conditions along the coast. From Cape Cod South along the coast to the Outerbanks expect Fair to Marginal conditions.

Looking inland North and North West from Cape Cod to Prince Edward Island , Expect Poor conditions to the West and North West. From Cape Cod South to the Delmarva looking Inland expect Poor to Marginal. Looking South West from NC to FL expect conditions to range from Poor to Good along the South West Gulf coast of FL. Looking South from NC to FL expect conditions inland to range from Marginal to Very Strong in central FL.
For Thursday From Prince Edward Island Canada along the coast to the VA/NC State Line expect Marginal to Moderate Conditions. With Moderate conditions fro Long Island to the Delmarva. From the VA / NC State Line along the coast to the NC / SC sate line expect Poor conditions. From Myrtle Beach SC to the FL Keys expect conditions to range from Fair to Good. Looking inland North from Cape Cod to Prince Edward Island Canada expect Fair to Marginal conditions to the North and North West. Looking inland from the Delmarva to Long Island expect conditions to range from Moderate to Fair to the North and North West. Looking inland from the Delmarva to the NC/SC Sate Line expect Poor conditions. Inland from Myrtle Beach to FL expect Fair to Good conditions the farther South you go, and expect conditions to range from Fair to Marginal to the South West from Myrtle Beach SC.
For Friday From Prince Edward Island Canada along the coast to the Jersey coast expect Poor to Marginal Conditions. From the Jersey coast South to the Outerbanks expect Poor Conditions. From the Outerbanks South Along the coast to the FL Keys expect Marginal to Moderate Conditions. Looking inland North and North West from the Jersey coast to Prince Edward Island Canada expect Poor conditions to the North and North West. Looking inland from the Outerbanks to Jersey expect Poor conditions to the North and North West. Looking inland from the SC Sate Line to the FL Keys expect Marginal to Good conditions to the South and South West.

<span style='color:blue'>Each Week I will try to add a little on Tropospheric Dx Modes in an effort to give a better understand as to how this forcast can help you in making 2 meter ssb, 70 cm ssb and 6 meter ssb DX Contacts. I'm not an expert and don't profess to be one. I know what I have studied in class and read. So, here goes. </span>
<span style='color:violet'>Tropospheric Enhancement (TrE)..(akaTropospheric Refraction)</span> <span style='color:blue'>is common under normal conditions. On most clear nights with calm or light winds..the ground radiates and the air near the ground cools. Eventually an inversion is formed and signals begin to refract off the inversion. Stations that normally fade in and out via tropo scatter come in continuously..with increasing strength. Also..weaker tropo scatter stations that are normally not heard (because their signal strengths never cross the background noise threshold signal level) also begin to appear. When the sun comes up..the ground & air heats up..the inversion breaks down..and the enhancement disappears. The enhancement is subtle on some nights..and very obvious on other nights. Distances are no different than your tropo scatter catches..it's just that the signals are stronger. Tropo enhancement is greatly influenced by terrain..with valley and coastal paths favoured. ("Fog-prone" areas are also "DX-prone" areas!!). From a DXers point of view, multiple directions usually are enhanced at the same time.
Here are some things that I do to help me determine when the Tropo might be at it's best:
1. Look at the hourly weather forecasts on the Weather Channel Web Site (weather.com) for my area and see when a inversion is most like to take place.
2. listen for beacons to the North and South. Beacons are usually low power and if you can hear them the there's a good possibility that Tropo is about.
3. if I hear other repeaters coming in on the same repeater frequencies as in my area this is a good sign of Tropo too.
4. Also FM radio broadcasts, anotherwords if you have distant stations interfering with the local broadcast.
5. If Fog starts to set in, this means that a Temp Inversion is taking place, which means that DX could result.
These are just some of the ways you can tell if Tropo is about.</span>
