MARCH 2015 – Key Weather Developments in 8 weather periods NOTE Timings are uncertain in these Wild-Jet-Stream / Mini-Ice-Age times – around +/-2days

MARCH 1-2/3 Solar Factors: NSF/Q 1-2 MOSTLY QUIETER THAN PREVIOUS PERIOD. PROBABLY LESS ACTIVITY (ESP 1-2) THAN STANDARD FORECASTS WILL EXPECT. High pressure (moving east) over Great Lakes/north-central USA. Low pressure Mexico/SW and NW USA/SW Canada. NE USA very cold, with snow showers, wind decreasing. Great Lakes and mid-west dry, cold, sharp frosts, THICK FOG. SE and Florida dry, variable sky, mildish afternoons, cold nights. West Gulf becoming milder, dry. SW quite warm, some thunder, variable sky. S California warm, variable sky. Rockies thunder and hail at times. NW cold, showers and misty. Snow showers Pacific, NW/Vancouver and NW USA. MARCH 2/3-7 Solar Factors: R5 3-5, R3 6-7, A MORE ACTIVE PERIOD WITH STRONGER WINDS AND HEAVIER SNOW/RAIN THAN STANDARD TV FORECASTS WILL EXPECT. A rapidly changing pattern with major active low pressure moving through central + mid-west and Great Lakes. Higher pressure generally in NW, West Gulf and E/SE coast. Very ferocious snow blizzards/ thundersnow + rain + floods in south over wide area central USA, mid-west & Great Lakes. East coast + SE + Florida variable sky, some showers, turning mild. Gulf becoming mild, with thunderstorms. West Gulf/south Texas probably dry, variable sky, becoming warm, threats of thunder. South California/far SW major snow, thunderstorms, hail + local floods. North half of west USA very cold, snow showers, mostly cloudy, thick fog at times. MARCH 8-10 Solar Factors: NSF/Q BECOMING WARM IN SOUTH AND WEST. Low pressure moving NE over mid-west and Great Lakes. High pressure south and east and NW USA. Low pressure far SW. NE USA, Great Lakes and mid-west extremely cold. South Canada and central N USA widespread heavy snow. Central USA thunderstorms and rain. South/east mild, dry and bright/sunny. SW very warm and mostly dry. South California thundery showers, humid and mild. West coast dry and mild. North of west very cold nights, bright/sunny. MARCH 11-14 Solar Factors: R2 11-12 & 13-14 DRAMATIC SW (WARM)/NE (COLD) CONTRASTS. Low pressure N/E USA moves NE. High pressure north of west linked to largely high pressure south USA. Low (s) in Pacific near SW USA and west coast. Extremely cold north central USA and NW Great Lakes. Heavy snow Great Lakes. Moderate wind rather than blizzards. S/E and most of Florida dry and mostly very fine. West gulf and Texas dry, very warm and sunny. SW USA dry, very warm/hot. Most of Rockies tremendous summery/spring weather. South California dry, warm, variable sky. NW USA dry and warm. North central-West bright and cold and very cold nights.

MARCH 15-18 Solar Factors: R4 15-18(19) VERY ACTIVE PERIOD WITH SW (MILD)/NE (COLD) CONTRASTS. A large active area of low pressure moves over N central parts and Great Lakes/mid-west towards NE. East coast high pressure. Gulf mostly low. Low off S California. North of west USA high pressure. A large area of heavy snow + bitter arctic winds in NE quarter of USA; moving to N/E. East and SE and most of Florida dry, warm and sunny. Gulf states humid and warm, with thunderstorms. S Texas major thunderstorms and giant hail. SW USA mostly dry, sunny and very warm. S California humid with thunderstorms, large hail and flash floods. North of west USA dry and sunny, cold nights. Warm days in NW Pacific areas. MARCH 19-22 Solar Factors: NSF/Q MOST PARTS MUCH WARMER; NE STILL COLD. Persistent low pressure centred in far NE extends across Great Lakes, mid-west and north central parts. High pressure SE quadrant of USA. Rockies and SW generally highish pressure, slack. Low pressure off S California. NE parts from north centre to far NE including mid-west, quite heavy snow and sleet. Thunderstorms in south parts. SE quadrant including Florida dry, fine, sunny, warm, great weather! Rockies and SW dry, very warm and sunny, fabulous weather! S California very warm, humid and some thundery showers. NW coast areas dry, sunny and warm. MARCH 23-28 Solar Factors: R2 24-25 & 26-27 A "west-east, high-low-high sandwich" After a confused change of flow patterns, an elongated WSW to ENE low becomes established sandwiched between highs in Canada and S/SE USA. Great Lakes, NE USA, mid-west and most of band from south Rockies to NE USA becoming showery and thundery in south of area with large hail. Ongoing snow showers Great Lakes + north central parts which are very cold. SE and Florida fine, dry, sunny and warm/very warm. SW USA thunderstorms. S California coolish with thunder and hail. West and NW becoming fine, dry and bright/sunny. North of W USA becoming dry and mostly sunny, with cold nights. MARCH 29-31 Solar Factors: R4 29-31 Change to West => East mobility Active Low North center USA to Great Lakes, High S/E quarter. Low Mexico. High West coast linked to High north of West USA – Canada. Developing area of snow / heavy snow and thundersnow at times from North Centre USA to Great Lakes / NE and , MidWest. Thunder-storms to S of region. NE USA dry and cold. SE + Florida Mostly dry, fine and warm. West Gulf Humid with thunder. SW dry+ Very warm with major thunder esp later. S California Variable / thundery showers. West/NW Snow and sleet. North Rockies Dry, Cold foggy.
