steady and heavy at times and kind of an ominous looking scene but dry condition cans right now in center city philadelphia, those low clouds in place after we did get a couple of rays earlier in the day. our temperature 60 degrees. we are below average but that south wind is pumping in the moisture. temperatures pretty cool across the region, 57 degrees in allentown, 50 in mount pocono. temperatures down the shore even a little bit cooler. 51 right now in ocean city all thanks to that easterly breeze off the ocean. ocean temperature right now 52 degrees. but we are seeing more in the way of sunshine right now down the shore sunshine breaking out sea isle city, atlantic city. where you see that cloud deck still very persistent as close as south jersey up into philly, lehigh valley and into the poconos and then off to the south and west we have harbingers of what's to come as we head into tonight and through the day tomorrow, this wide area of precipitation continuing to advance off the north and east and all of that moisture will be moving into

our backyard as we head into tonight, but we do need the rainfall. our rainfall deficit since march first, over three and a half inches, rainfall deficit so far this month closing in on 2-inches, so we need the april showers to bring in our may flowers with may right around the corner. and overnight tonight areas of rain develop, 48 degrees so a bit chilly tonight. light breezes tomorrow, wind speeds stay under 10 miles per hour. that is the good part of the forecast. temperatures still running below average and rain heavy at times especially as we head into the morning hours. that's when we're going to see the steadiest of the rainfall. so what to expect? a very soggy sunday in store. amounts about a half inch to maybe a quarter of an inch in some spots and not even going rule out an embedded thunderstorm. so, future weather going to show us we are dry into the evening hours. so if you have those saturday evening plans, you're looking all right. but as we head past midnight, the rain starts to build in especially north and west of the city. by tomorrow morning, 8 o'clock, broad street run, that rain is going to be coming down in center city

philadelphia and some pockets of heavier rain. as we head into lunchtime, still dealing with periods of rain, maybe a lull into the afternoon hours but then rain returns as we head into the evening hours a chance of a rumble of thunder. as we head into monday morning, some spotty showers around. kind of have more in the way of hit or miss showers on monday but we could see a few thunderstorms popping as we led into the second half of monday afternoon. future weather showing us that with some bull's eyes of heavier red monday with daytime heating. future weather amounts, as we head into the day tomorrow just giving us about .4 of an inch. i think we'll see more than that. monday even more wet weather in store from with those rainfall totals surpassing an inch in some spots and we'll be dealing with this unsettled weather pattern as we head into next week for a good portion for the first half of may because of this persistent

trough in place and also temperatures are going to be about average but we're not going to be cruising well above average. we do that just a bit on wednesday. 72 degrees, our average right now is in the upper 60's to near 70 degrees. you're going to need your umbrella really every day of the week. the driest day looks like wednesday time before more rain moves in wednesday night. thursday is looking pretty wet. so -- >> seriously rain every day. >> every day dealing with some rain. we'll make up for the deficit at least. >> okay, well, one whole week. thank you lauren. lesley's got sports highlights. draft is over. >> last day of the draft. one local guy getting accident happened up. eagles had five picks today. so far they have picked another offensive lineman running back safety cornerback and defensive lineman. in the fifth round eagles picked running back wendell small wood from west virginia, the wilmington delaware native led the big 12 in rushing last year and ran a 4:46, 40-yard
